 name: diagnose
 description: Disciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says "diagnose this" / "debug this", reports a bug, says something is broken/throwing/failing, or describes a performance regression.
 ---
 # Diagnose
 A discipline for hard bugs. Skip phases only when explicitly justified.
 When exploring the codebase, use the project's domain glossary to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.
 ## Phase 1 — Build a feedback loop
 **This is the skill.** Everything else is mechanical. If you have a fast, deterministic, agent-runnable pass/fail signal for the bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume that signal. If you don't have one, no amount of staring at code will save you.
 Spend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**
 ### Ways to construct one — try them in roughly this order
 1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.
 2. **Curl / HTTP script** against a running dev server.
 3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.
 4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.
 5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.
 6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.
 7. **Property / fuzz loop.** If the bug is "sometimes wrong output", run 1000 random inputs and look for the failure mode.
 8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate "boot at state X, check, repeat" so you can `git bisect run` it.
 9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.
 10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.
 Build the right feedback loop, and the bug is 90% fixed.
 ### Iterate on the loop itself
 Treat the loop as a product. Once you have _a_ loop, ask:
 - Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)
 - Can I make the signal sharper? (Assert on the specific symptom, not "didn't crash".)
 - Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)
 A 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.
 ### Non-deterministic bugs
 The goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.
 ### When you genuinely cannot build a loop
 Stop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.
 Do not proceed to Phase 2 until you have a loop you believe in.
 ## Phase 2 — Reproduce
 Run the loop. Watch the bug appear.
 Confirm:
 - [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.
 - [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).
 - [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.
 Do not proceed until you reproduce the bug.
 ## Phase 3 — Hypothesise
 Generate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.
 Each hypothesis must be **falsifiable**: state the prediction it makes.
 > Format: "If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse."
 If you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.
 **Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly ("we just deployed a change to #3"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.
 ## Phase 4 — Instrument
 Each probe must map to a specific prediction from Phase 3. **Change one variable at a time.**
 Tool preference:
 1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.
 2. **Targeted logs** at the boundaries that distinguish hypotheses.
 3. Never "log everything and grep".
 **Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.
 **Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.
 ## Phase 5 — Fix + regression test
 Write the regression test **before the fix** — but only if there is a **correct seam** for it.
 A correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.
 **If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.
 If a correct seam exists:
 1. Turn the minimised repro into a failing test at that seam.
 2. Watch it fail.
 3. Apply the fix.
 4. Watch it pass.
 5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.
 ## Phase 6 — Cleanup + post-mortem
 Required before declaring done:
 - [ ] Original repro no longer reproduces (re-run the Phase 1 loop)
 - [ ] Regression test passes (or absence of seam is documented)
 - [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)
 - [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)
 - [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns
 **Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics. Make the recommendation **after** the fix is in, not before — you have more information now than when you started.

 description: Invoke when a project is too large or you only want the core design insights. Extracts 1-2 standout design patterns with deep analysis, lens-guided perspectives, and migration examples. Not for full project analysis or quick lookups.

 # Essence: Extract Core Design Patterns
 Prefix your first line with 🥷 inline, not as its own paragraph.
 You are a jewel inspector. A project has thousands of files — your job is to find the one or two brilliant ideas worth stealing.
 **This is NOT a lite version of `/explore`.** `/explore` reads the whole project and summarizes at the end. `/essence` goes deep on one thing and ignores everything else.
 ## Mode Selection
 First, check whether an `/explore` result exists:
 - `/explore` report exists → it already identified 2-3 core designs, default to **User-directed**. Ask the user which design to deep-dive, or whether to switch mode.
 - No `/explore` result → this is an independent launch, default to **Auto-detect**.
 Always confirm before proceeding:
 | Mode | When | Entry |
 |---|---|---|
 | **User-directed** | Already have a design target from `/explore`, or know exactly which design to investigate | User tells you what to look for |
 | **Auto-detect** | Independent launch, project is large, want the AI to find the standout design | You find the standout design |
 | **Lens-guided** | "Analyze this from a [mechanical/intentional/evolution] perspective" | Apply a specific analytical lens |
 ### Lens definitions
 | Lens | Core question | Guided behavior |
 |---|---|---|
 | **Mechanical** (default) | How does it work? | Read source code, trace call chains, examine interfaces |
 | **Intentional** | Why this way? | Read design docs/RFCs/PRs, extract decision rationale and tradeoffs |
 | **Evolution** | How did it get here? | Read git history/changelog, compare before/after, identify migration drivers |
 A lens shapes which sources to read and how to frame the output, but does not add separate phases.
 ### Auto-detect signals
 A design is "essence" if it passes 2 or more of these signals:
 | Signal | Evidence |
 |---|---|
 | README highlights it prominently | "Built on a plugin architecture" as a headline feature |
 | Has standalone architecture docs | ARCHITECTURE.md, docs/design/, blog post by author |
 | Heavily discussed in Issues/PRs | Design decisions debated by community |
 | Unique among similar projects | Competitors don't do it this way |
 | Rich design comments in code | JSDoc/TSDoc explaining why, not what |
 | Cross-module contract | A type, interface, or protocol imported across module boundaries (not just files). Go: most-implemented interface. Python: most-subclassed abstract base. Rust: most-implemented trait. These define subsystem relationships. |
 | File size anomaly | One file is disproportionately large or small for its responsibility — signals non-trivial logic |
 | Dedicated test coverage | Tests specifically validate this design's behavior, not just happy paths |
 **"Clean code" is NOT a signal.** A well-written utility function is not essence. An architecture decision that shapes the entire project is.
 If no design passes 2+ signals, tell the user: "This project has no standout design. Try `/explore` for a full analysis instead."
 ## Phase 1: Locate
 **User-directed mode:**
 - Go directly to the directory or file the user names.
 - If the directory doesn't exist, stop and tell the user. Do NOT invent an alternative.
 **Auto-detect mode:**
 - Scan README, AGENTS.md, and top-level docs for architecture claims.
 - Identify 1-2 standout design directions.
 - Present to the user: "The standout designs appear to be: A) {design A}, B) {design B}. Which should we dive into?"
 - If user doesn't choose, pick the strongest one and state why.
 **Lens-guided mode:**
 - Confirm the lens with the user (Mechanical/Intentional/Evolution).
 - Frame the search in terms of the lens.
 - Example: "You want the Mechanical view — I'll trace the core implementation and extract the pattern."
 **Output:** 1-2 design directions to analyze + lens confirmation.
 **Stall signal:** Cannot identify any standout design → the project may be a conventional CRUD app or wrapper. Stop and recommend `/explore` or a different project.
 ## Phase 2: Deep Dive
 Read the core files related to the chosen design. Maximum 10 files. Let the lens guide source selection: Mechanical → source code and type definitions; Intentional → design docs, RFCs, PR discussions; Evolution → git history, changelog, migration guides.
 **For each file:**
 - What role does it play in this design?
 - What interfaces does it expose?
 - How does it connect to other parts of the system?
 **Trace the call chain:**
 - Start from the entry point that uses this design.
 - Follow the flow until you understand the full pattern.
 - Stop when you hit boilerplate, config, or test files.
 **Output:** Core file list (≤10) + call chain + lens-specific annotations.
 **Stall signal:** The design spans more than 10 files and you can't find the boundary → the design is probably the project's core architecture. Switch to `/explore` for a full analysis instead.
 ## Phase 3: Extract Pattern
 Analyze the design at a higher level. Let the lens shape the analysis angle:
 - **Mechanical** → emphasize structure, interfaces, data flow — produce a pattern diagram + interface contracts
 - **Intentional** → emphasize decision rationale, tradeoffs — produce a decision record (context → options → rationale)
 - **Evolution** → emphasize before/after comparison, migration drivers — produce a timeline + catalyst events
 **Universal analysis dimensions** (all lenses):
 - **Problem:** What specific problem does this design solve? What was the pain before?
 - **Pattern:** What's the name of this pattern? (Named: MVC, Observer, Plugin, Middleware. Custom: describe it in one sentence.)
 - **Alternatives:** What simpler or more complex approaches could solve the same problem?
 - **Tradeoffs:** Why did the author choose this? What does it give up?
 - **Evidence:** What in the code proves this analysis is correct? (Specific files, functions, comments.)
 **Output:** Design pattern card (lens-framed).
 **Stall signal:** Cannot explain why the author chose this design over alternatives → read commit messages and PR discussions for design rationale. If unavailable, state "author's reasoning unknown" in the report.
 ## Phase 4: Migrate
 Make the learning actionable. Let the lens tailor the output:
 - **Mechanical** → copy-paste code skeleton (≤20 lines with TODOs)
 - **Intentional** → decision framework (checklist for evaluating tradeoffs)
 - **Evolution** → migration path (step-by-step refactor plan)
 **Universal deliverables** (all lenses):
 - **Can you use this?** Is the design applicable to the user's own projects? If not, why?
 - **Steal-it example:** A simplified version (under 20 lines) that captures the core idea. Not production code — a teaching example.
 - **Pitfalls:** What context does this design depend on? What would break if you copy it blindly?
 **Output:** Migration example + pitfall list (lens-tailored).
 **Stall signal:** The design depends on framework internals, language features, or ecosystem the user doesn't have → explain the core idea abstractly instead of providing code.
 ## Phase 5: Self-review
 Check the report is honest:
 **All modes:**
 - [ ] The design is real (not inferred, not imagined). Evidence: specific files cited.
 - [ ] The analysis is deep enough that you could explain it out loud.
 - [ ] The migration example captures the core idea, not surface syntax.
 - [ ] Pitfalls are specific, not vague ("needs X version" not "may not work everywhere").
 **Stall signals (any one → return to relevant phase):**
 - Cannot name a file that proves the pattern → back to Phase 2
 - Cannot explain why it's better than alternatives → back to Phase 3
 - Migration example is over 20 lines → simplify, back to Phase 4
 - Lens-specific check failed (e.g., Mechanical missing end-to-end call chain, Intentional missing decision rationale, Evolution missing timeline) → back to relevant phase
 **Output:** Essence report with lens annotation.

 ## Hard Rules
 - **No code evidence = no conclusion.** Every claim about a design must cite a specific file, function, or comment.
 - **Under 20 lines for migration examples.** If you can't explain the idea in 20 lines, you don't understand it well enough.
 - **Stop after the report.** Do not modify the user's project or the target project.
 - **HTML is optional.** Do not block analysis on HTML generation.

 # Essence Detection Signals
 How to identify the standout design in a project when the user doesn't specify a direction.
 ## Signal Strength
 A design passes the "essence" threshold if it scores 2+ signals.
 ### Strong Signals (score = 1 each)
 | Signal | How to detect | Example |
 |---|---|---|
 | **README headline** | Project name is followed by a design claim | "Vite — Next generation frontend tooling with **ESM-first architecture**" |
 | **Architecture docs** | Standalone design document exists | `ARCHITECTURE.md`, `docs/design/`, `docs/architecture/` |
 | **Official blog post** | Author wrote about the design on their blog | tw93.fun, Vite blog, React blog posts |
 | **Community discussion** | Issues/PRs debate the design decision | "Why we chose X over Y" discussions with many comments |
 | **Rich code comments** | JSDoc/TSDoc explaining WHY, not WHAT | "We use this pattern because..." with detailed reasoning |
 ### Objective Signals (score = 1 each, no subjective judgment needed)
 | Signal | How to detect | Example |
 |---|---|---|
 | **Cross-module contract** | A type, interface, or protocol imported across module boundaries (not just files). Go: most-implemented interface. Python: most-subclassed abstract base. Rust: most-implemented trait. | `Plugin` interface implemented by 8 subsystems, each in its own package |
 | **File size anomaly** | One file's line count is ≥3× the median for its category (handlers, utils, etc.) | Average handler: 50 lines. One handler: 800 lines with state machine logic |
 | **Dedicated test coverage** | Tests exist specifically for this design's edge cases, not just happy paths | `plugin.test.ts` tests plugin resolution, fallback, lifecycle — not just "it loads" |
 ### Weak Signals (score = 0.5 each)
 | Signal | How to detect | Example |
 |---|---|---|
 | **Unique among competitors** | Same category, different architecture | Next.js uses SSR, Remix uses nested routes — that difference IS the essence |
 | **Most-starred files** | GitHub shows stars/bookmarks on specific files | "This file has 200+ stars on GitHub" |
 | **Core algorithm** | One file contains non-trivial logic that drives the project | Diff algorithm, compiler pass, state machine |
 | **API design** | The public API is notably elegant or unusual | `create()` returns a builder chain, not an object |
 ## Not Signals
 These do NOT count as essence:
 - "Clean code" or "well organized" — that's quality, not design
 - "Uses TypeScript" — that's a language choice, not architecture
 - "Has good tests" — that's engineering discipline, not design
 - "Many stars on the repo" — popularity ≠ design quality
 - "Uses the latest framework" — following trends ≠ standing out
 - Utility functions — even well-written ones are tools, not designs
 ## Auto-detect Procedure
 When the user says "find the essence":
 1. **Read README fully.** What is the #1 feature the author leads with? That's a candidate.
 2. **Check for design docs.** Is there `ARCHITECTURE.md` or equivalent? That's a candidate.
 3. **Scan the import graph.** Which file is imported by the most other files? Use `grep -r "import.*from" src/ | sort | uniq -c | sort -rn` or equivalent. The top result is likely the core.
 4. **Check file sizes.** Are any files disproportionately large or small for their apparent role? That signals hidden complexity.
 5. **Check uniqueness.** Compare with 1-2 well-known alternatives. What does this project do differently?
 6. **Present 1-2 candidates** to the user with evidence. Let them choose or auto-select the strongest.
 ### Example Output Format
 ```
 Standout designs in {project}:
 A) {Design A name} — evidenced by {README claim / file / doc}
   What it does: {one sentence}
 B) {Design B name} — evidenced by {code comment / unique feature / community discussion}
   What it does: {one sentence}
 Which should we dive into? (or I can pick the strongest)
 ```
 ## Failure Modes
 | Situation | Response |
 |---|---|
 | No signal passes 2+ threshold | "This project uses conventional architecture. Try `/explore` for a full analysis, or pick a more architecturally interesting project." |
 | User-specified module doesn't exist | Stop. Do NOT suggest an alternative. Tell the user the path doesn't exist. |
 | Project is a wrapper (thin layer over another tool) | "This project is primarily a wrapper around {X}. The design is in {X}, not here. Try analyzing {X} instead." |
 | Project is configuration-only (just JSON/YAML files) | "This project has no code architecture. It's configuration-driven. Try `/explore` for a full overview instead." |

 # Explore: Project Understanding and Onboarding
 Prefix your first line with 🥷 inline, not as its own paragraph.
 You are a project cartographer. Your job is to help the user understand what a project is, why it is worth studying, how it is organized, and where to start.
 `/explore` is the entry point for first contact with a repository or project-like artifact. It builds global understanding. It does not perform code-level essence extraction and it does not run interactive teaching.
 ## Project Type Detection
 After the initial scan, classify the target before continuing:
 | Type | Signals | What changes |
 |---|---|---|
 | **Code repository** | `go.mod`, `pyproject.toml`, `Cargo.toml`, source directories, executable entrypoints | Run all 4 phases |
 | **Skill / docs / knowledge repository** | `SKILL.md`, mostly Markdown, docs-first structure, no runnable application entrypoint | Skip Phase 2 (Flow) and Phase 3 (Start Path) |
 | **Template / scaffold repository** | Starter files, minimal logic, setup-first repo | Phase 2 may stay structural and Phase 3 may be minimal |
 State the detected type before proceeding. If uncertain, say what evidence is missing and continue with the closest matching type.
 ## Phase 1: Positioning & Structure
 - What this project is, why it is worth studying, and who it is for.
 - Top-level structure: main modules, documents, directories, and the likely learning entry area.
 - Tradeoffs vs alternatives when evidence exists.
 ## Phase 2: Flow
 **Code repositories only.**
 - Skip for non-code and template repositories.
 - Trace the main runtime or request flow.
 - Produce at least one architecture or core-flow diagram.
 - Keep the trace focused on the golden path rather than exhaustive coverage.
 ## Phase 3: Start Path
 **Code repositories only when runnable or meaningfully inspectable.**
 - Provide the minimal path to start learning or running the project.
 - Give the first command or first inspection step.
 - Suggest one safe first modification or observation point when appropriate.
 ## Phase 4: Core Designs
 - Summarize 2-3 core implementations or ideas.
 - Keep this at overview depth.
 - For each item, include what it is, where it lives, and why it matters.
 ## Minimum Deliverables
 The final `/explore` report must include:
 - Project positioning
 - Why it is worth studying
 - 2-3 core implementations or core ideas
 - Tradeoffs or comparisons when applicable
 - At least 1 diagram:
  - code repository → architecture diagram or core flow diagram
  - non-code repository → structure diagram, idea map, or workflow diagram
 ## Boundary Rules
 `/explore` may:
 - scan structure
 - explain the main flow
 - provide a minimal start path
 - summarize 2-3 core designs
 `/explore` must not:
 - perform `/essence`-level deep extraction
 - act as `/follow`-style guided teaching
 - include Verify, Deep Fission, or HTML Output phases
 - preserve no retired lightweight fallback behavior
 ## Outcome
 ```
 Explore Report: {project name}
 Project type: code / skill-docs / template
 Phases completed: 4/4 (or note skipped code-only phases)
 Diagram included: yes / no
 Core designs: 2-3
 Status: complete

 After the report, stop. Do not proceed to `/essence` or `/follow` automatically.

 # Project Analysis Methods
 How to read and understand an unfamiliar code project.
 ## 1. Identify the Entry Point
 Every project has a door. Find it first.
 ### By Language
 | Language | Look for |
 |---|---|
 | **JavaScript/TypeScript** | `package.json` → `main` / `bin` / `scripts.dev` |
 | **Python** | `setup.py` → `entry_points`, `pyproject.toml` → `[project.scripts]`, or top-level `app.py` / `main.py` / `__main__.py` |
 | **Go** | `package main` in any file, conventionally `main.go` or `cmd/*/main.go` |
 | **Rust** | `src/main.rs` or `src/bin/*.rs` |
 | **Java** | Class with `public static void main(String[] args)` |
 | **C/C++** | `main()` function, conventionally in `src/main.c` |
 | **Swift** | `main.swift` or file with `@main` attribute |
 ### In Frameworks
 | Framework | Entry point |
 |---|---|
 | Next.js | `app/` or `pages/` directory, `next.config.js` |
 | React (Vite) | `src/main.tsx` or `src/main.jsx` |
 | Vue (Vite) | `src/main.ts` or `src/main.js` |
 | Express | File that calls `app.listen()` |
 | FastAPI | File that creates `FastAPI()` instance |
 | Django | `manage.py`, then project name directory with `urls.py` / `wsgi.py` |
 | Flask | `app.py` or `app/__init__.py` |
 | Spring Boot | `*Application.java` with `@SpringBootApplication` |
 ## 2. Judge Project Complexity
 Don't over-engineer simple projects. Don't under-analyze complex ones.
 ### Simple (<50 files, single language)
 - Read every source file.
 - No need for flow diagrams beyond a simple sequence.
 - A light `/explore` pass is probably enough.
 ### Standard (50-500 files, 1-2 languages)
 - Read entry point + core modules + 1-2 feature files.
 - Build 1-2 flow diagrams.
 - `/explore` is the right level.
 ### Complex (>500 files, multi-language, monorepo)
 - Read entry point + architecture docs + one representative module.
 - Use `/essence` to find standout designs, or `/explore` for one package at a time.
 - Do NOT try to understand the whole project in one pass.
 ## 3. Separate Core Code from Scaffolding
 Not all files are worth reading.
 ### Ignore (scaffolding)
 - `*.config.js`, `*.config.ts` — configuration, not logic
 - `dist/`, `build/`, `out/` — generated output
 - `node_modules/`, `vendor/`, `.venv/` — dependencies
 - `*.lock`, `yarn.lock`, `go.sum` — lock files
 - `LICENSE`, `CODEOWNERS`, `.editorconfig` — project meta
 - `test/fixtures/`, `test/data/` — test data
 ### Read (core)
 - Entry point file
 - Router/middleware/config handlers
 - Model/entity/schema definitions
 - Core algorithm or business logic files
 - Files referenced most in imports
 ### Hint: Follow imports
 ```
 entry file → import A → import B → core logic
 ```
 Each import is a dependency. Follow the chain until you hit a file that doesn't import anything else — that's usually the core.
 ## 4. Read Unfamiliar Framework Code
 You don't know every framework. That's fine.
 ### Strategy
 1. **Find the routing layer first.** Every framework has a way to map URLs or events to handlers. Find it. It tells you the project's capabilities.
 2. **Follow ONE request end-to-end.** Don't try to understand all routes. Pick the simplest one (often "health check" or "get by ID") and trace it from entry to response.
 3. **Identify the framework's conventions.** Most frameworks follow a pattern:
   - MVC: Controller → Model → View
   - Middleware: Request → Middleware chain → Handler → Response
   - Component: Parent renders children, props flow down, events flow up
   - Plugin: Core calls hooks, plugins register handlers
 4. **Don't fight the framework's abstraction.** If the project uses ORM, don't look for raw SQL. If it uses dependency injection, don't look for `new()` calls. Understand what abstraction layer they chose.
 5. **Use the framework's own docs.** If stuck on "how does this framework work?", check the official docs. Don't reverse-engineer what's documented.

 # Flow Pattern Library
 Common architecture patterns and how to identify them in code.
 ## MVC / MVVM / MVX
 ### What it is
 Separation of data (Model), UI/presentation (View), and coordination logic (Controller/ViewModel).
 ### File signatures
 | Pattern | Directories/Files |
 |---|---|
 | **MVC** | `controllers/`, `models/`, `views/` |
 | **MVVM** | `viewmodels/`, `views/`, `models/` |
 | **Layered** | `app/`, `domain/`, `infrastructure/` (Clean/Hexagonal) |
 ### Flow
 ```
 Request → Controller → Model (data) → View (render) → Response
 ```
 ### Key question
 "Does the file handle data, display, or coordination?" If yes → MVC-family.
 ---
 ## Middleware Chain
 ### What it is
 Each handler processes the request and passes it to the next. Like an assembly line.
 ### File signatures
 | Framework | Indicator |
 |---|---|---|
 | **Express/Koa** | `app.use(...)`, `app.get('/', handler)` |
 | **FastAPI** | `@app.middleware("http")`, `Depends()` |
 | **Next.js** | `middleware.ts` at root or in `app/` |
 | **Gin (Go)** | `router.Use(middleware1, middleware2)` |
 | **Koa** | `app.use(async (ctx, next) => { ... })` |
 ### Flow
 ```
 Request → Middleware A → Middleware B → Handler → Response
               ↓              ↓
          auth check     log request
 ```
 ### Key question
 "Does this function call `next()` or pass control to something else?" If yes → middleware.
 ### Common middleware order
 ```
 1. CORS / Security headers
 2. Logging / Request ID
 3. Authentication / Authorization
 4. Body parsing / Validation
 5. Rate limiting
 6. Route handler
 7. Error handler (catches everything above)
 ```
 ---
 ## Plugin / Extension System
 ### What it is
 Core provides hooks or interfaces. External code registers handlers. The core doesn't know about specific plugins.
 ### File signatures
 | Pattern | Indicator |
 |---|---|
 | **Hook-based** | `registerHook('eventName', handler)`, `hooks.on('event', fn)` |
 | **Interface-based** | Abstract class or interface that plugins implement |
 | **Discovery-based** | Directory scan (`plugins/`), import all, register by convention |
 | **VSCode-style** | `contributes` in `package.json`, activation events |
 ### Flow
 ```
 Core starts
    ↓
 Scans for plugins
    ↓
 Each plugin registers itself
    ↓
 Core fires hooks → plugins respond
    ↓
 Core runs with extended capabilities
 ```
 ### Key question
 "Can I add functionality without modifying core code?" If yes → plugin architecture.
 ---
 ## Event-Driven
 ### What it is
 Components communicate through events, not direct calls. Publishers emit, subscribers listen.
 ### File signatures
 | Pattern | Indicator |
 |---|---|
 | **Node EventEmitter** | `eventEmitter.on('event', handler)`, `eventEmitter.emit('event', data)` |
 | **Pub/Sub** | `pubsub.subscribe('channel', handler)`, `pubsub.publish('channel', data)` |
 | **Redux-style** | `dispatch(action)`, `reducer(state, action) → newState` |
 | **Observable** | `observable.subscribe(fn)`, `pipe(map, filter)` |
 | **Signals (Python)** | `@signal.connect`, `signal.send()` |
 ### Flow
 ```
 Component A emits "user.created"
    ↓
 Listener B hears it → sends welcome email
 Listener C hears it → creates default settings
 Listener D hears it → logs analytics
 ```
 ### Key question
 "Does code communicate without importing or calling each other directly?" If yes → event-driven.
 ---
 ## State Management
 ### What it is
 Centralized storage for application state. Components read and update through defined interfaces.
 ### File signatures
 | Pattern | Indicator |
 |---|---|
 | **Redux** | `createStore()`, `dispatch()`, `useSelector()`, `@reduxjs/toolkit` |
 | **Zustand** | `create((set) => ({ ... }))` |
 | **Jotai** | `atom(value)`, `useAtom(atom)` |
 | **MobX** | `@observable`, `@action`, `@computed` |
 | **React Context** | `createContext()`, `useContext()`, `Provider` |
 | **Pinia (Vue)** | `defineStore()`, `state`, `actions` |
 ### Flow
 ```
 Component dispatches action
    ↓
 Reducer processes action + current state
    ↓
 New state emitted
    ↓
 Subscribed components re-render
 ```
 ### Key question
 "Where does the app store data that multiple components need?" If it's a single store → state management pattern.
 ---
 ## Pipeline / Chain of Responsibility
 ### What it is
 Data flows through a series of processors. Each processor transforms the data and passes it on.
 ### File signatures
 | Pattern | Indicator |
 |---|---|
 | **Stream processing** | `.pipe(transform1).pipe(transform2)` |
 | **Compiler/lexer** | Source → Tokenize → Parse → Transform → Generate |
 | **Data pipeline** | `input → transform → validate → output` |
 | **Makefile** | Target depends on prerequisites, each is a step |
 ### Flow
 ```
 Raw input → Tokenizer → Parser → Transformer → Generator → Output
 ```
 ### Key question
 "Does data get progressively transformed through a fixed sequence of steps?" If yes → pipeline.

 name: follow
 description: Invoke when the user wants an interactive learning session based on an existing `/explore` or `/essence` report. Guides runnable or reader-style follow-along sessions. Not for fresh project analysis or pattern-only extraction.
 metadata:
  version: "0.5.0"
 ---
 # Follow: Guided Learning Session
 Prefix your first line with 🥷 inline, not as its own paragraph.
 You are a guide. The user wants to learn from a project step by step with help, context, and correction. You guide the learning process, but you do not replace it.
 `/follow` is not a fresh project analyzer. It only works from an existing `/explore` or `/essence` result.
 ## Pre-check
 `/follow` only works when there is already an `/explore` report or an `/essence` report.
 - `/explore` report exists → use it as the main learning path
 - `/essence` report exists → use it for design-focused guided study
 - Neither exists → refuse clearly
 Refusal behavior:
 "I need an existing `/explore` or `/essence` result before I can guide a follow-along session. Please run `/explore` for project understanding or `/essence` for a focused deep dive first."
 Load the existing report before continuing.
 ## Mode Selection
 After the pre-check, select one mode based on the prerequisite report:
 - From `/explore` + code repository → default **Runnable**
 - From `/explore` + non-code repository → force **Reader**
 - From `/essence` → default **Reader** (user is in design-analysis state)
 | Mode | When | Entry |
 |---|---|---|
 | **Runnable** | Report confirms the project is a runnable code repository and the user wants to learn by running and changing it | Start from environment and first execution |
 | **Reader** | Project has no runtime, or the user is studying design/architecture, or the prerequisite report is from `/essence` | Start from guided reading |
 State the selected mode before proceeding. Do not re-scan the project — use the prerequisite report to decide.
 ## Teaching Interaction Rules
 `/follow` must teach by guidance, not by dumping answers:
 - explain the purpose of the current step first
 - give the user an observation point or action point
 - ask the user to predict, try, or explain before revealing the answer
 - then reveal, correct, or deepen the explanation
 - never say "go read the code" as a standalone instruction. When referencing code, always start with: what design idea this code embodies, why it matters in the overall architecture, and what the user should pay attention to
 ## Runnable Check
 Before Runnable mode, confirm from the **prerequisite report** (do not re-scan the project):
 - If the report identified the target as a code repository with a recognized runtime (`go.mod`, `pyproject.toml`, `Cargo.toml`, `Makefile`, `build.gradle`, `pom.xml`, `CMakeLists.txt`, etc.), proceed with Runnable.
 - If the report classified it as non-code, or no runtime entrypoint was found, switch to Reader and explain why.
 - If the prerequisite is `/essence`, confirm with the user: essence is design-focused, Reader is the natural fit. Allow Runnable only if the user explicitly insists.
 - Do not introduce a third mode.
 ## Runnable Mode Flow
 1. Confirm environment and prerequisites.
 2. Let the user run the project.
 3. Let the user make one safe change.
 4. Walk the main flow together.
 5. Give one small exercise.
 6. Review what they learned.
 ## Reader Mode Flow
 1. Frame the learning goal around a core design or architectural idea, not a single file.
 2. Walk through the design concept layer by layer: problem → approach → implementation → tradeoff.
 3. Ask the user questions that probe understanding ("Why did the author choose this approach over a simpler one?"), not just prediction ("What happens next?").
 4. Use diagrams or structured summaries to connect the dots between files and design ideas.
 5. Give one reasoning exercise that tests whether the user can apply the design pattern elsewhere.
 6. Review what they learned.
 ## Boundary Rules
 `/follow` must:
 - depend on `/explore` or `/essence`
 - guide the user interactively
 - adapt between code and non-code repositories through Runnable or Reader emphasis
 `/follow` must not:
 - rescan the whole project as a new analyzer
 - reference retired skills as prerequisites
 - add any third learning mode
 - execute commands or write code for the user
 ## Outcome
 ```
 Follow Session: {project name}
 Mode: runnable / reader
 Prerequisite report: /explore or /essence
 Exercise result: completed / partial / too hard
 Next direction: {suggested follow-up}
 Status: complete
 ```
 After the review, stop. Ask whether the user wants another exercise or wants to end the session.

 # Environment Detection Rules
 How to detect the runtime environment and guide the user through setup in `/follow`.
 ## Language Detection from Config
 Check these files in order. The first match is the primary language.
 | Config file | Language | Runtime check | Install command |
 |---|---|---|---|
 | `package.json` | JavaScript/TypeScript | `node --version` | nvm or official installer |
 | `pyproject.toml` | Python | `python --version` | pyenv or python.org |
 | `go.mod` | Go | `go version` | golang.org/dl |
 | `Cargo.toml` | Rust | `rustc --version` | rustup |
 | `pom.xml` | Java | `java -version` | SDKMAN or official |
 | `build.gradle` / `build.gradle.kts` | Java/Kotlin | `java -version` | SDKMAN |
 | `Gemfile` | Ruby | `ruby --version` | rvm or rbenv |
 | `*.csproj` | C#/.NET | `dotnet --version` | .NET SDK |
 | `CMakeLists.txt` | C/C++ | `gcc --version` or `clang --version` | System package manager |
 | `swift package.json` | Swift | `swift --version` | Xcode or swift.org |
 ## Dependency Installation
 Once language is detected, guide the user:
 ### JavaScript/TypeScript
 ```bash
 # Check which package manager is used
 if [ -f "yarn.lock" ]; then yarn install
 elif [ -f "pnpm-lock.yaml" ]; then pnpm install
 elif [ -f "bun.lockb" ] || [ -f "bun.lock" ]; then bun install
 else npm install
 fi
 ```
 ### Python
 ```bash
 # Modern Python projects
 pip install -e .
 # Or with requirements
 pip install -r requirements.txt
 # Or with poetry
 poetry install
 # Or with uv
 uv pip install -r requirements.txt
 ```
 ### Go
 ```bash
 go mod download
 ```
 ### Rust
 ```bash
 cargo build
 ```
 ### Java (Maven)
 ```bash
 mvn install
 ```
 ### Java (Gradle)
 ```bash
 ./gradlew build
 # or
 gradle build
 ```
 ## Run Command Detection
 How to start the project:
 | Source | Command |
 |---|---|
 | `package.json` → `scripts.dev` | `npm run dev` |
 | `package.json` → `scripts.start` | `npm start` |
 | `Makefile` → `dev` target | `make dev` |
 | `Makefile` → `run` target | `make run` |
 | `pyproject.toml` (Poetry) | `poetry run python main.py` |
 | `go.mod` → `package main` | `go run main.go` |
 | `Cargo.toml` → `[[bin]]` | `cargo run` |
 | `docker-compose.yml` exists | `docker-compose up` |
 | `Dockerfile` exists, no compose | `docker build -t app . && docker run app` |
 ## Common Environment Issues
 | Error | Cause | Fix |
 |---|---|---|
 | `command not found: node` | Node.js not installed | Install Node.js (recommend LTS) |
 | `ModuleNotFoundError` | Python deps not installed | Run `pip install -r requirements.txt` |
 | `EACCES: permission denied` | Global install without sudo | Use nvm/fnm, or prefix with sudo |
 | `ENOENT: no such file` | Wrong working directory | `cd` to project root first |
 | `port already in use` | Another process on same port | Kill the process or use different port |
 | `go: cannot find main module` | Outside Go module | `cd` to directory with `go.mod` |
 | `error: could not find Cargo.toml` | Outside Rust project | `cd` to directory with `Cargo.toml` |
 | `java.lang.UnsupportedClassVersionError` | Wrong Java version | Match JDK version to project requirement |
 | `npm ERR! code ERESOLVE` | Dependency conflict | Try `npm install --legacy-peer-deps` |
 ## Detection Script for /follow
 ```bash
 # Quick environment check
 echo "=== Environment ==="
 node --version 2>/dev/null || echo "Node.js: not installed"
 python --version 2>/dev/null || echo "Python: not installed"
 go version 2>/dev/null || echo "Go: not installed"
 rustc --version 2>/dev/null || echo "Rust: not installed"
 java -version 2>/dev/null || echo "Java: not installed"
 echo "PWD: $(pwd)"
 ```
 Run this at the start of `/follow` Step 1 to understand what's available.

 # Frontend Design — Complete Guidance
 This document provides a comprehensive framework for creating visually distinctive, non-templated UI designs. Here's the full breakdown:
 ## Foundational Approach
 Act as the design lead for a studio known for unique client identities — the client has already turned down template-like proposals. Every choice about palette, typography, and layout must be specific to the brief, including "one real aesthetic risk you can justify."
 ## Grounding in Subject Matter
 If the brief is vague about the product or subject, pin it down yourself: name the subject, its audience, and the page's single job. Draw inspiration from "the subject's own world, its materials, instruments, artifacts, and vernacular." Use any known context about the human's preferences or past designs as hints.
 ## Design Principles
 - **Hero as thesis**: Open with "the most characteristic thing in the subject's world" — avoid default choices like a big number with a small label and gradient accent unless truly optimal.
 - **Typography**: Pair display and body faces deliberately, not from your usual repertoire. Set a clear type scale with intentional weights, widths, and spacing. "Make the type treatment itself a memorable part of the design."
 - **Structure as information**: Numbering, eyebrows, dividers must encode something true about the content. Question whether numbered markers (01/02/03) actually make sense before using them — only appropriate for real sequences.
 - **Motion**: Consider where animation serves the subject. "An orchestrated moment usually lands harder than scattered effects." Sometimes less is better to avoid an AI-generated feel.
 - **Complexity**: Match execution to the vision — maximalist needs elaborate execution, minimal needs precision.
 - **Content**: Come up with copy if the brief lacks it. Poor copy makes a design feel as templated as poor layout.
 ## AI-Generated Design Traps
 Three common AI-default looks to watch for: (1) warm cream background (~#F4F1EA) with serif display and terracotta accent; (2) near-black with bright acid-green or vermilion; (3) broadsheet layout with hairline rules, zero border-radius, and dense columns. "All three are legitimate for some briefs, but they are defaults rather than choices." Where the brief leaves an axis free, don't spend that freedom on a default.
 ## Two-Pass Process
 **Pass 1 — Plan**: Create a compact token system:
 1. **Color**: 4–6 named hex values
 2. **Type**: Characterful display face (used with restraint), complementary body face, utility face for captions/data
 3. **Layout**: One-sentence prose descriptions + ASCII wireframes
 4. **Signature**: The single unique element the page will be remembered by
 Review the plan against the brief. If any part reads like what you'd produce for any similar page, revise it. Only then write code.
 **Pass 2 — Build**: Follow the revised plan exactly. Watch for CSS selector specificity conflicts (e.g., `.section` and `.cta` fighting over padding/margins). Do most planning internally, only sharing ideas when confident.
 ## Restraint & Self-Critique
 "Spend your boldness in one place" — let the signature element be the one memorable thing; keep everything else quiet. "Not taking a risk can be a risk itself!" Build responsively down to mobile, with visible keyboard focus and reduced motion respected. Critique as you build. Follow Chanel's advice: before finishing, remove one accessory. Jot notes about what you've tried to avoid repeating yourself.
 ## Writing in Design
 Words exist to make the design understandable and usable — they're "design material, not decoration." Write from the end user's perspective, naming things by what people control and recognize, never by how the system is built.
 - Use active voice as default
 - A control should say exactly what happens: "Save changes," not "Submit"
 - Maintain consistent vocabulary throughout flows (button says "Publish," toast says "Published")
 - Treat errors as guidance, not mood — explain what went wrong and how to fix it
 - Empty screens are invitations to act
 - Keep the register conversational: "plain verbs, sentence case, no filler"
 - Let each element do exactly one job — "a label labels, an example demonstrates"

 ---
 # GitNexus CLI Commands
 All commands work via `npx` — no global install required.
 ## Commands
 ### analyze — Build or refresh the index
 ```bash
 npx gitnexus analyze
 ```
 Run from the project root. This parses all source files, builds the knowledge graph, writes it to `.gitnexus/`, and generates AGENTS.md / AGENTS.md context files.
 | Flag           | Effect                                                           |
 | -------------- | ---------------------------------------------------------------- |
 | `--force`      | Force full re-index even if up to date                           |
 | `--embeddings` | Enable embedding generation for semantic search (off by default) |
 | `--drop-embeddings` | Drop existing embeddings on rebuild. By default, an `analyze` without `--embeddings` preserves them. |
 **When to run:** First time in a project, after major code changes, or when `gitnexus://repo/{name}/context` reports the index is stale. In Codex, a PostToolUse hook detects staleness after `git commit` and `git merge` and notifies the agent to run `analyze` — the hook does not run analyze itself, to avoid blocking the agent for up to 120s and risking KuzuDB corruption on timeout.
 ### status — Check index freshness
 ```bash
 npx gitnexus status
 ```
 Shows whether the current repo has a GitNexus index, when it was last updated, and symbol/relationship counts. Use this to check if re-indexing is needed.
 ### clean — Delete the index
 ```bash
 npx gitnexus clean
 ```
 Deletes the `.gitnexus/` directory and unregisters the repo from the global registry. Use before re-indexing if the index is corrupt or after removing GitNexus from a project.
 | Flag      | Effect                                            |
 | --------- | ------------------------------------------------- |
 | `--force` | Skip confirmation prompt                          |
 | `--all`   | Clean all indexed repos, not just the current one |
 ### wiki — Generate documentation from the graph
 ```bash
 npx gitnexus wiki
 ```
 Generates repository documentation from the knowledge graph using an LLM. Requires an API key (saved to `~/.gitnexus/config.json` on first use).
 | Flag                | Effect                                    |
 | ------------------- | ----------------------------------------- |
 | `--force`           | Force full regeneration                   |
 | `--model <model>`   | LLM model (default: minimax/minimax-m2.5) |
 | `--base-url <url>`  | LLM API base URL                          |
 | `--api-key <key>`   | LLM API key                               |
 | `--concurrency <n>` | Parallel LLM calls (default: 3)           |
 | `--gist`            | Publish wiki as a public GitHub Gist      |
 ### list — Show all indexed repos
 ```bash
 npx gitnexus list
 ```
 Lists all repositories registered in `~/.gitnexus/registry.json`. The MCP `list_repos` tool provides the same information.
 ## After Indexing
 1. **Read `gitnexus://repo/{name}/context`** to verify the index loaded
 2. Use the other GitNexus skills (`exploring`, `debugging`, `impact-analysis`, `refactoring`) for your task
 ## Troubleshooting
 - **"Not inside a git repository"**: Run from a directory inside a git repo
 - **Index is stale after re-analyzing**: Restart Codex to reload the MCP server
 - **Embeddings slow**: Omit `--embeddings` (it's off by default) or set `OPENAI_API_KEY` for faster API-based embedding

 # Debugging with GitNexus
 ## When to Use
 - "Why is this function failing?"
 - "Trace where this error comes from"
 - "Who calls this method?"
 - "This endpoint returns 500"
 - Investigating bugs, errors, or unexpected behavior
 ## Workflow
 ```
 1. gitnexus_query({query: "<error or symptom>"})            → Find related execution flows
 2. gitnexus_context({name: "<suspect>"})                    → See callers/callees/processes
 3. READ gitnexus://repo/{name}/process/{name}                → Trace execution flow
 4. gitnexus_cypher({query: "MATCH path..."})                 → Custom traces if needed
 ```
 > If "Index is stale" → run `npx gitnexus analyze` in terminal.
 ## Checklist
 ```
 - [ ] Understand the symptom (error message, unexpected behavior)
 - [ ] gitnexus_query for error text or related code
 - [ ] Identify the suspect function from returned processes
 - [ ] gitnexus_context to see callers and callees
 - [ ] Trace execution flow via process resource if applicable
 - [ ] gitnexus_cypher for custom call chain traces if needed
 - [ ] Read source files to confirm root cause
 ```
 ## Debugging Patterns
 | Symptom              | GitNexus Approach                                          |
 | -------------------- | ---------------------------------------------------------- |
 | Error message        | `gitnexus_query` for error text → `context` on throw sites |
 | Wrong return value   | `context` on the function → trace callees for data flow    |
 | Intermittent failure | `context` → look for external calls, async deps            |
 | Performance issue    | `context` → find symbols with many callers (hot paths)     |
 | Recent regression    | `detect_changes` to see what your changes affect           |
 ## Tools
 **gitnexus_query** — find code related to error:
 ```
 gitnexus_query({query: "payment validation error"})
 → Processes: CheckoutFlow, ErrorHandling
 → Symbols: validatePayment, handlePaymentError, PaymentException
 ```
 **gitnexus_context** — full context for a suspect:
 ```
 gitnexus_context({name: "validatePayment"})
 → Incoming calls: processCheckout, webhookHandler
 → Outgoing calls: verifyCard, fetchRates (external API!)
 → Processes: CheckoutFlow (step 3/7)
 ```
 **gitnexus_cypher** — custom call chain traces:
 ```cypher
 MATCH path = (a)-[:CodeRelation {type: 'CALLS'}*1..2]->(b:Function {name: "validatePayment"})
 RETURN [n IN nodes(path) | n.name] AS chain
 ```
 ## Example: "Payment endpoint returns 500 intermittently"
 ```
 1. gitnexus_query({query: "payment error handling"})
   → Processes: CheckoutFlow, ErrorHandling
   → Symbols: validatePayment, handlePaymentError
 2. gitnexus_context({name: "validatePayment"})
   → Outgoing calls: verifyCard, fetchRates (external API!)
 3. READ gitnexus://repo/my-app/process/CheckoutFlow
   → Step 3: validatePayment → calls fetchRates (external)
 4. Root cause: fetchRates calls external API without proper timeout

 ## Tools
 **gitnexus_query** — find execution flows related to a concept:
 ```
 gitnexus_query({query: "payment processing"})
 → Processes: CheckoutFlow, RefundFlow, WebhookHandler
 → Symbols grouped by flow with file locations
 ```
 **gitnexus_context** — 360-degree view of a symbol:
 ```
 gitnexus_context({name: "validateUser"})
 → Incoming calls: loginHandler, apiMiddleware

 # GitNexus Guide
 Quick reference for all GitNexus MCP tools, resources, and the knowledge graph schema.
 ## Always Start Here
 For any task involving code understanding, debugging, impact analysis, or refactoring:
 1. **Read `gitnexus://repo/{name}/context`** — codebase overview + check index freshness
 2. **Match your task to a skill below** and **read that skill file**
 3. **Follow the skill's workflow and checklist**
 > If step 1 warns the index is stale, run `npx gitnexus analyze` in the terminal first.
 ## Skills
 | Task                                         | Skill to read       |

 # Impact Analysis with GitNexus
 ## When to Use
 - "Is it safe to change this function?"
 - "What will break if I modify X?"
 - "Show me the blast radius"
 - "Who uses this code?"
 - Before making non-trivial code changes
 - Before committing — to understand what your changes affect
 ## Workflow
 ```
 1. gitnexus_impact({target: "X", direction: "upstream"})  → What depends on this
 2. READ gitnexus://repo/{name}/processes                   → Check affected execution flows
 3. gitnexus_detect_changes()                               → Map current git changes to affected flows
 4. Assess risk and report to user
 ```
 > If "Index is stale" → run `npx gitnexus analyze` in terminal.
 ## Checklist
 ```
 - [ ] gitnexus_impact({target, direction: "upstream"}) to find dependents
 - [ ] Review d=1 items first (these WILL BREAK)
 - [ ] Check high-confidence (>0.8) dependencies
 - [ ] READ processes to check affected execution flows
 - [ ] gitnexus_detect_changes() for pre-commit check
 - [ ] Assess risk level and report to user
 ```
 ## Understanding Output
 | Depth | Risk Level       | Meaning                  |
 | ----- | ---------------- | ------------------------ |
 | d=1   | **WILL BREAK**   | Direct callers/importers |
 | d=2   | LIKELY AFFECTED  | Indirect dependencies    |
 | d=3   | MAY NEED TESTING | Transitive effects       |
 ## Risk Assessment
 | Affected                       | Risk     |
 | ------------------------------ | -------- |
 | <5 symbols, few processes      | LOW      |
 | 5-15 symbols, 2-5 processes    | MEDIUM   |
 | >15 symbols or many processes  | HIGH     |
 | Critical path (auth, payments) | CRITICAL |
 ## Tools
 **gitnexus_impact** — the primary tool for symbol blast radius:
 ```
 gitnexus_impact({
  target: "validateUser",
  direction: "upstream",
  minConfidence: 0.8,
  maxDepth: 3
 })
 → d=1 (WILL BREAK):
  - loginHandler (src/auth/login.ts:42) [CALLS, 100%]
  - apiMiddleware (src/api/middleware.ts:15) [CALLS, 100%]
 → d=2 (LIKELY AFFECTED):
  - authRouter (src/routes/auth.ts:22) [CALLS, 95%]
 ```
 **gitnexus_detect_changes** — git-diff based impact analysis:
 ```
 gitnexus_detect_changes({scope: "staged"})
 → Changed: 5 symbols in 3 files
 → Affected: LoginFlow, TokenRefresh, APIMiddlewarePipeline
 → Risk: MEDIUM
 ```
 ## Example: "What breaks if I change validateUser?"
 ```
 1. gitnexus_impact({target: "validateUser", direction: "upstream"})
   → d=1: loginHandler, apiMiddleware (WILL BREAK)
   → d=2: authRouter, sessionManager (LIKELY AFFECTED)
 2. READ gitnexus://repo/my-app/processes
   → LoginFlow and TokenRefresh touch validateUser
 3. Risk: 2 direct callers, 2 processes = MEDIUM

 description: "Use when the user wants to rename, extract, split, move, or restructure code safely. Examples: \"Rename this function\", \"Extract this into a module\", \"Refactor this class\", \"Move this to a separate file\""
 ---
 # Refactoring with GitNexus
 ## When to Use
 - "Rename this function safely"
 - "Extract this into a module"
 - "Split this service"
 - "Move this to a new file"
 - Any task involving renaming, extracting, splitting, or restructuring code
 ## Workflow
 ```
 1. gitnexus_impact({target: "X", direction: "upstream"})  → Map all dependents
 2. gitnexus_query({query: "X"})                            → Find execution flows involving X
 3. gitnexus_context({name: "X"})                           → See all incoming/outgoing refs
 4. Plan update order: interfaces → implementations → callers → tests
 ```
 > If "Index is stale" → run `npx gitnexus analyze` in terminal.
 ## Checklists
 ### Rename Symbol
 ```
 - [ ] gitnexus_rename({symbol_name: "oldName", new_name: "newName", dry_run: true}) — preview all edits
 - [ ] Review graph edits (high confidence) and ast_search edits (review carefully)
 - [ ] If satisfied: gitnexus_rename({..., dry_run: false}) — apply edits
 - [ ] gitnexus_detect_changes() — verify only expected files changed
 - [ ] Run tests for affected processes
 ```
 ### Extract Module
 ```
 - [ ] gitnexus_context({name: target}) — see all incoming/outgoing refs
 - [ ] gitnexus_impact({target, direction: "upstream"}) — find all external callers
 - [ ] Define new module interface
 - [ ] Extract code, update imports
 - [ ] gitnexus_detect_changes() — verify affected scope
 - [ ] Run tests for affected processes
 ```
 ### Split Function/Service
 ```
 - [ ] gitnexus_context({name: target}) — understand all callees
 - [ ] Group callees by responsibility
 - [ ] gitnexus_impact({target, direction: "upstream"}) — map callers to update
 - [ ] Create new functions/services
 - [ ] Update callers
 - [ ] gitnexus_detect_changes() — verify affected scope
 - [ ] Run tests for affected processes
 ```
 ## Tools
 **gitnexus_rename** — automated multi-file rename:
 ```
 gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: true})
 → 12 edits across 8 files
 → 10 graph edits (high confidence), 2 ast_search edits (review)
 → Changes: [{file_path, edits: [{line, old_text, new_text, confidence}]}]
 ```
 **gitnexus_impact** — map all dependents first:
 ```
 gitnexus_impact({target: "validateUser", direction: "upstream"})
 → d=1: loginHandler, apiMiddleware, testUtils
 → Affected Processes: LoginFlow, TokenRefresh
 ```
 **gitnexus_detect_changes** — verify your changes after refactoring:
 ```
 gitnexus_detect_changes({scope: "all"})
 → Changed: 8 files, 12 symbols
 → Affected processes: LoginFlow, TokenRefresh
 → Risk: MEDIUM
 ```
 **gitnexus_cypher** — custom reference queries:
 ```cypher
 MATCH (caller)-[:CodeRelation {type: 'CALLS'}]->(f:Function {name: "validateUser"})
 RETURN caller.name, caller.filePath ORDER BY caller.filePath
 ```
 ## Risk Rules
 | Risk Factor         | Mitigation                                |
 | ------------------- | ----------------------------------------- |
 | Many callers (>5)   | Use gitnexus_rename for automated updates |
 | Cross-area refs     | Use detect_changes after to verify scope  |
 | String/dynamic refs | gitnexus_query to find them               |
 | External/public API | Version and deprecate properly            |
 ## Example: Rename `validateUser` to `authenticateUser`
 ```
 1. gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: true})
   → 12 edits: 10 graph (safe), 2 ast_search (review)
   → Files: validator.ts, login.ts, middleware.ts, config.json...
 2. Review ast_search edits (config.json: dynamic reference!)
 3. gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: false})
   → Applied 12 edits across 8 files
 4. gitnexus_detect_changes({scope: "all"})
   → Affected: LoginFlow, TokenRefresh
   → Risk: MEDIUM — run tests for these flows

 # ADR Format
 ADRs live in `docs/adr/` and use sequential numbering: `0001-slug.md`, `0002-slug.md`, etc.
 Create the `docs/adr/` directory lazily — only when the first ADR is needed.
 ## Template
 ```md
 # {Short title of the decision}
 {1-3 sentences: what's the context, what did we decide, and why.}
 ```
 That's it. An ADR can be a single paragraph. The value is in recording *that* a decision was made and *why* — not in filling out sections.
 ## Optional sections
 Only include these when they add genuine value. Most ADRs won't need them.
 - **Status** frontmatter (`proposed | accepted | deprecated | superseded by ADR-NNNN`) — useful when decisions are revisited
 - **Considered Options** — only when the rejected alternatives are worth remembering
 - **Consequences** — only when non-obvious downstream effects need to be called out
 ## Numbering
 Scan `docs/adr/` for the highest existing number and increment by one.
 ## When to offer an ADR
 All three of these must be true:
 1. **Hard to reverse** — the cost of changing your mind later is meaningful
 2. **Surprising without context** — a future reader will look at the code and wonder "why on earth did they do it this way?"
 3. **The result of a real trade-off** — there were genuine alternatives and you picked one for specific reasons
 If a decision is easy to reverse, skip it — you'll just reverse it. If it's not surprising, nobody will wonder why. If there was no real alternative, there's nothing to record beyond "we did the obvious thing."
 ### What qualifies
 - **Architectural shape.** "We're using a monorepo." "The write model is event-sourced, the read model is projected into Postgres."
 - **Integration patterns between contexts.** "Ordering and Billing communicate via domain events, not synchronous HTTP."
 - **Technology choices that carry lock-in.** Database, message bus, auth provider, deployment target. Not every library — just the ones that would take a quarter to swap out.
 - **Boundary and scope decisions.** "Customer data is owned by the Customer context; other contexts reference it by ID only." The explicit no-s are as valuable as the yes-s.
 - **Deliberate deviations from the obvious path.** "We're using manual SQL instead of an ORM because X." Anything where a reasonable reader would assume the opposite. These stop the next engineer from "fixing" something that was deliberate.
 - **Constraints not visible in the code.** "We can't use AWS because of compliance requirements." "Response times must be under 200ms because of the partner API contract."
 - **Rejected alternatives when the rejection is non-obvious.** If you considered GraphQL and picked REST for subtle reasons, record it — otherwise someone will suggest GraphQL again in six months.

 # CONTEXT.md Format
 ## Structure
 ```md
 # {Context Name}
 {One or two sentence description of what this context is and why it exists.}
 ## Language
 **Order**:
 {A concise description of the term}
 _Avoid_: Purchase, transaction
 **Invoice**:
 A request for payment sent to a customer after delivery.
 _Avoid_: Bill, payment request
 **Customer**:
 A person or organization that places orders.
 _Avoid_: Client, buyer, account
 ## Relationships
 - An **Order** produces one or more **Invoices**
 - An **Invoice** belongs to exactly one **Customer**
 ## Example dialogue
 > **Dev:** "When a **Customer** places an **Order**, do we create the **Invoice** immediately?"
 > **Domain expert:** "No — an **Invoice** is only generated once a **Fulfillment** is confirmed."
 ## Flagged ambiguities
 - "account" was used to mean both **Customer** and **User** — resolved: these are distinct concepts.
 ```
 ## Rules
 - **Be opinionated.** When multiple words exist for the same concept, pick the best one and list the others as aliases to avoid.
 - **Flag conflicts explicitly.** If a term is used ambiguously, call it out in "Flagged ambiguities" with a clear resolution.
 - **Keep definitions tight.** One sentence max. Define what it IS, not what it does.
 - **Show relationships.** Use bold term names and express cardinality where obvious.
 - **Only include terms specific to this project's context.** General programming concepts (timeouts, error types, utility patterns) don't belong even if the project uses them extensively. Before adding a term, ask: is this a concept unique to this context, or a general programming concept? Only the former belongs.
 - **Group terms under subheadings** when natural clusters emerge. If all terms belong to a single cohesive area, a flat list is fine.
 - **Write an example dialogue.** A conversation between a dev and a domain expert that demonstrates how the terms interact naturally and clarifies boundaries between related concepts.
 ## Single vs multi-context repos
 **Single context (most repos):** One `CONTEXT.md` at the repo root.
 **Multiple contexts:** A `CONTEXT-MAP.md` at the repo root lists the contexts, where they live, and how they relate to each other:
 ```md
 # Context Map
 ## Contexts
 - [Ordering](./src/ordering/CONTEXT.md) — receives and tracks customer orders
 - [Billing](./src/billing/CONTEXT.md) — generates invoices and processes payments
 - [Fulfillment](./src/fulfillment/CONTEXT.md) — manages warehouse picking and shipping
 ## Relationships
 - **Ordering → Fulfillment**: Ordering emits `OrderPlaced` events; Fulfillment consumes them to start picking
 - **Fulfillment → Billing**: Fulfillment emits `ShipmentDispatched` events; Billing consumes them to generate invoices
 - **Ordering ↔ Billing**: Shared types for `CustomerId` and `Money`
 ```
 The skill infers which structure applies:
 - If `CONTEXT-MAP.md` exists, read it to find contexts
 - If only a root `CONTEXT.md` exists, single context
 - If neither exists, create a root `CONTEXT.md` lazily when the first term is resolved
 When multiple contexts exist, infer which one the current topic relates to. If unclear, ask.

 description: Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions.
 ---
 <what-to-do>
 Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer.
 Ask the questions one at a time, waiting for feedback on each question before continuing.
 If a question can be answered by exploring the codebase, explore the codebase instead.
 </what-to-do>
 <supporting-info>
 ## Domain awareness
 During codebase exploration, also look for existing documentation:
 ### File structure
 Most repos have a single context:
 ```
 /
 ├── CONTEXT.md
 ├── docs/
 │   └── adr/
 │       ├── 0001-event-sourced-orders.md
 │       └── 0002-postgres-for-write-model.md
 └── src/
 ```
 If a `CONTEXT-MAP.md` exists at the root, the repo has multiple contexts. The map points to where each one lives:
 ```
 /
 ├── CONTEXT-MAP.md
 ├── docs/
 │   └── adr/                          ← system-wide decisions
 ├── src/
 │   ├── ordering/
 │   │   ├── CONTEXT.md
 │   │   └── docs/adr/                 ← context-specific decisions
 │   └── billing/
 │       ├── CONTEXT.md
 │       └── docs/adr/
 ```
 Create files lazily — only when you have something to write. If no `CONTEXT.md` exists, create one when the first term is resolved. If no `docs/adr/` exists, create it when the first ADR is needed.
 ## During the session
 ### Challenge against the glossary
 When the user uses a term that conflicts with the existing language in `CONTEXT.md`, call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?"
 ### Sharpen fuzzy language
 When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account' — do you mean the Customer or the User? Those are different things."
 ### Discuss concrete scenarios
 When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts.
 ### Cross-reference with code
 When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?"
 ### Update CONTEXT.md inline
 When a term is resolved, update `CONTEXT.md` right there. Don't batch these up — capture them as they happen. Use the format in [CONTEXT-FORMAT.md](./CONTEXT-FORMAT.md).
 `CONTEXT.md` should be totally devoid of implementation details. Do not treat `CONTEXT.md` as a spec, a scratch pad, or a repository for implementation decisions. It is a glossary and nothing else.
 ### Offer ADRs sparingly
 Only offer to create an ADR when all three are true:
 1. **Hard to reverse** — the cost of changing your mind later is meaningful
 2. **Surprising without context** — a future reader will wonder "why did they do it this way?"
 3. **The result of a real trade-off** — there were genuine alternatives and you picked one for specific reasons
 If any of the three is missing, skip the ADR. Use the format in [ADR-FORMAT.md](./ADR-FORMAT.md).

 Implement tasks from an OpenSpec change.
 **Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
 **Steps**
 1. **Select the change**
   If a name is provided, use it. Otherwise:
   - Infer from conversation context if the user mentioned a change
   - Auto-select if only one active change exists
   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
 2. **Check status to understand the schema**
   ```bash
   openspec status --change "<name>" --json
   ```
   Parse the JSON to understand:
   - `schemaName`: The workflow being used (e.g., "spec-driven")
   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
 3. **Get apply instructions**
   ```bash
   openspec instructions apply --change "<name>" --json
   ```
   This returns:
   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
   - Progress (total, complete, remaining)
   - Task list with status
   - Dynamic instruction based on current state
   **Handle states:**
   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
   - If `state: "all_done"`: congratulate, suggest archive
   - Otherwise: proceed to implementation
 4. **Read context files**
   Read every file path listed under `contextFiles` from the apply instructions output.
   The files depend on the schema being used:
   - **spec-driven**: proposal, specs, design, tasks
   - Other schemas: follow the contextFiles from CLI output
 5. **Show current progress**
   Display:
   - Schema being used
   - Progress: "N/M tasks complete"
   - Remaining tasks overview
   - Dynamic instruction from CLI
 6. **Implement tasks (loop until done or blocked)**
   For each pending task:
   - Show which task is being worked on
   - Make the code changes required
   - Keep changes minimal and focused
   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
   - Continue to next task
   **Pause if:**
   - Task is unclear → ask for clarification
   - Implementation reveals a design issue → suggest updating artifacts
   - Error or blocker encountered → report and wait for guidance
   - User interrupts
 7. **On completion or pause, show status**
   Display:
   - Tasks completed this session
   - Overall progress: "N/M tasks complete"
   - If all done: suggest archive
   - If paused: explain why and wait for guidance

 ```
 **Guardrails**
 - Keep going through tasks until done or blocked
 - Always read context files before starting (from the apply instructions output)
 - If task is ambiguous, pause and ask before implementing
 - If implementation reveals issues, pause and suggest artifact updates
 - Keep code changes minimal and scoped to each task
 - Update task checkbox immediately after completing each task
 - Pause on errors, blockers, or unclear requirements - don't guess
 - Use contextFiles from CLI output, don't assume specific file names
 **Fluid Workflow Integration**
 This skill supports the "actions on a change" model:
 - **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
 - **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

 Archive a completed change in the experimental workflow.
 **Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
 **Steps**
 1. **If no change name provided, prompt for selection**
   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
   Show only active changes (not already archived).
   Include the schema used for each change if available.
   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
 2. **Check artifact completion status**
   Run `openspec status --change "<name>" --json` to check artifact completion.
   Parse the JSON to understand:
   - `schemaName`: The workflow being used
   - `artifacts`: List of artifacts with their status (`done` or other)
   **If any artifacts are not `done`:**
   - Display warning listing incomplete artifacts
   - Use **AskUserQuestion tool** to confirm user wants to proceed
   - Proceed if user confirms
 3. **Check task completion status**
   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
   **If incomplete tasks found:**
   - Display warning showing count of incomplete tasks
   - Use **AskUserQuestion tool** to confirm user wants to proceed
   - Proceed if user confirms
   **If no tasks file exists:** Proceed without task-related warning.
 4. **Assess delta spec sync state**
   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
   **If delta specs exist:**
   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
   - Determine what changes would be applied (adds, modifications, removals, renames)
   - Show a combined summary before prompting
   **Prompt options:**
   - If changes needed: "Sync now (recommended)", "Archive without syncing"
   - If already synced: "Archive now", "Sync anyway", "Cancel"
   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
 5. **Perform the archive**
   Create the archive directory if it doesn't exist:
   ```bash
   mkdir -p openspec/changes/archive
   ```
   Generate target name using current date: `YYYY-MM-DD-<change-name>`
   **Check if target already exists:**
   - If yes: Fail with error, suggest renaming existing archive or using different date
   - If no: Move the change directory to archive
   ```bash
   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
   ```
 6. **Display summary**
   Show archive completion summary including:
   - Change name
   - Schema that was used
   - Archive location
   - Whether specs were synced (if applicable)
   - Note about any warnings (incomplete artifacts/tasks)
 **Output On Success**
 ```
 ## Archive Complete
 **Change:** <change-name>
 **Schema:** <schema-name>
 **Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
 **Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
 All artifacts complete. All tasks complete.
 ```
 **Guardrails**
 - Always prompt for change selection if not provided
 - Use artifact graph (openspec status --json) for completion checking
 - Don't block archive on warnings - just inform and confirm
 - Preserve .openspec.yaml when moving to archive (it moves with the directory)
 - Show clear summary of what happened
 - If sync is requested, use openspec-sync-specs approach (agent-driven)
 - If delta specs exist, always run the sync assessment and show the combined summary before prompting

 Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
 **IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
 **This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
 ---
 ## The Stance
 - **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
 - **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
 - **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
 - **Adaptive** - Follow interesting threads, pivot when new information emerges
 - **Patient** - Don't rush to conclusions, let the shape of the problem emerge
 - **Grounded** - Explore the actual codebase when relevant, don't just theorize
 ---
 ## What You Might Do
 Depending on what the user brings, you might:
 **Explore the problem space**
 - Ask clarifying questions that emerge from what they said
 - Challenge assumptions
 - Reframe the problem
 - Find analogies
 **Investigate the codebase**
 - Map existing architecture relevant to the discussion
 - Find integration points
 - Identify patterns already in use
 - Surface hidden complexity
 **Compare options**
 - Brainstorm multiple approaches
 - Build comparison tables
 - Sketch tradeoffs
 - Recommend a path (if asked)
 **Visualize**

 ```
 **Surface risks and unknowns**
 - Identify what could go wrong
 - Find gaps in understanding
 - Suggest spikes or investigations
 ---
 ## OpenSpec Awareness
 You have full context of the OpenSpec system. Use it naturally, don't force it.
 ### Check for context
 At the start, quickly check what exists:
 ```bash
 openspec list --json
 ```
 This tells you:
 - If there are active changes
 - Their names, schemas, and status
 - What the user might be working on
 ### When no change exists
 Think freely. When insights crystallize, you might offer:
 - "This feels solid enough to start a change. Want me to create a proposal?"
 - Or keep exploring - no pressure to formalize
 ### When a change exists
 If the user mentions a change or you detect one is relevant:
 1. **Read existing artifacts for context**
   - `openspec/changes/<name>/proposal.md`
   - `openspec/changes/<name>/design.md`
   - `openspec/changes/<name>/tasks.md`
   - etc.
 2. **Reference them naturally in conversation**
   - "Your design mentions using Redis, but we just realized SQLite fits better..."
   - "The proposal scopes this to premium users, but we're now thinking everyone..."
 3. **Offer to capture when decisions are made**
    | Insight Type               | Where to Capture               |
    |----------------------------|--------------------------------|
    | New requirement discovered | `specs/<capability>/spec.md` |
    | Requirement changed        | `specs/<capability>/spec.md` |
    | Design decision made       | `design.md`                  |
    | Scope changed              | `proposal.md`                |
    | New work identified        | `tasks.md`                   |
    | Assumption invalidated     | Relevant artifact              |
   Example offers:
   - "That's a design decision. Capture it in design.md?"
   - "This is a new requirement. Add it to specs?"
   - "This changes scope. Update the proposal?"
 4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
 ---
 ## What You Don't Have To Do
 - Follow a script
 - Ask the same questions every time
 - Produce a specific artifact
 - Reach a conclusion
 - Stay on topic if a tangent is valuable
 - Be brief (this is thinking time)

 ## Ending Discovery
 There's no required ending. Discovery might:
 - **Flow into a proposal**: "Ready to start? I can create a change proposal."
 - **Result in artifact updates**: "Updated design.md with these decisions"
 - **Just provide clarity**: User has what they need, moves on
 - **Continue later**: "We can pick this up anytime"
 When it feels like things are crystallizing, you might summarize:
 ```
 ## What We Figured Out
 **The problem**: [crystallized understanding]
 **The approach**: [if one emerged]
 **Open questions**: [if any remain]
 **Next steps** (if ready):
 - Create a change proposal
 - Keep exploring: just keep talking
 ```
 But this summary is optional. Sometimes the thinking IS the value.
 ---
 ## Guardrails
 - **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
 - **Don't fake understanding** - If something is unclear, dig deeper
 - **Don't rush** - Discovery is thinking time, not task time
 - **Don't force structure** - Let patterns emerge naturally
 - **Don't auto-capture** - Offer to save insights, don't just do it
 - **Do visualize** - A good diagram is worth many paragraphs
 - **Do explore the codebase** - Ground discussions in reality
 - **Do question assumptions** - Including the user's and your own

 Propose a new change - create the change and generate all artifacts in one step.
 I'll create a change with artifacts:
 - proposal.md (what & why)
 - design.md (how)
 - tasks.md (implementation steps)
 When ready to implement, run /opsx:apply
 ---
 **Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
 **Steps**
 1. **If no clear input provided, ask what they want to build**
   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
   > "What change do you want to work on? Describe what you want to build or fix."
   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
 2. **Create the change directory**
   ```bash
   openspec new change "<name>"
   ```
   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
 3. **Get the artifact build order**
   ```bash
   openspec status --change "<name>" --json
   ```
   Parse the JSON to get:
   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
   - `artifacts`: list of all artifacts with their status and dependencies
 4. **Create artifacts in sequence until apply-ready**
   Use the **TodoWrite tool** to track progress through the artifacts.
   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
   a. **For each artifact that is `ready` (dependencies satisfied)**:
      - Get instructions:
        ```bash
        openspec instructions <artifact-id> --change "<name>" --json
        ```
      - The instructions JSON includes:
        - `context`: Project background (constraints for you - do NOT include in output)
        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
        - `template`: The structure to use for your output file
        - `instruction`: Schema-specific guidance for this artifact type
        - `outputPath`: Where to write the artifact
        - `dependencies`: Completed artifacts to read for context
      - Read any completed dependency files for context
      - Create the artifact file using `template` as the structure
      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
      - Show brief progress: "Created <artifact-id>"
   b. **Continue until all `applyRequires` artifacts are complete**
      - After creating each artifact, re-run `openspec status --change "<name>" --json`
      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
      - Stop when all `applyRequires` artifacts are done
   c. **If an artifact requires user input** (unclear context):
      - Use **AskUserQuestion tool** to clarify
      - Then continue with creation
 5. **Show final status**
   ```bash
   openspec status --change "<name>"
   ```
 **Output**
 After completing all artifacts, summarize:
 - Change name and location
 - List of artifacts created with brief descriptions
 - What's ready: "All artifacts created! Ready for implementation."
 - Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
 **Artifact Creation Guidelines**
 - Follow the `instruction` field from `openspec instructions` for each artifact type
 - The schema defines what each artifact should contain - follow it
 - Read dependency artifacts for context before creating new ones
 - Use `template` as the structure for your output file - fill in its sections
 - **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
  - These guide what you write, but should never appear in the output
 **Guardrails**
 - Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
 - Always read dependency artifacts before creating a new one
 - If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
 - If a change with that name already exists, ask if user wants to continue it or create a new one
 - Verify each artifact file exists after writing before proceeding to next

 # 内置执行协议
 本文件只在外部 OpenSpec CLI 或子 skill 不可用时使用。fallback 不是跳过阶段，而是由 sm-flow 用文件方式完成同等最小产物。每次使用 fallback 都必须写入 `decisions.md` 或 `acceptance.md`，说明能力来源、缺失能力、影响和剩余风险。
 ## 通用规则
 - 优先使用外部能力；只有不可用、不可发现或无法在当前环境调用时才使用内置协议。
 - 不得因为使用 fallback 跳过 context、grill、commit、apply 授权或 archive 确认。
 - fallback 产物仍写入 `openspec/changes/{slug}/` 和 `devflow/projects/YYYY-MM-DD-{slug}/`。
 - 如果内置协议也无法满足阶段退出条件，暂停并向用户说明阻塞项。
 ## grill 内置协议
 - 建立 question pool，至少覆盖术语、边界、验收；涉及参考实现或项目基础设施时加入技术实现问题。
 - 将问题标记为 `evidence-driven` 或 `user-interview`。
 - 先查证 evidence-driven 问题并汇报结论，再逐个询问 user-interview 问题。
 - 按 `references/scales.md` 的当前分档满足 grill 要求。
 - 将 question pool、证据结论、用户原话和确认状态写入 `decisions.md`；影响实现的结论回写 `proposal.md`。
 ## openspec 提案内置协议
 - 在 `openspec/changes/{slug}/` 创建或更新：
  - `proposal.md`：问题、方案、范围、非目标、上下文约束、风险。
  - 设计产物：实现设计、接口影响、关键决策、架构风险；形式按 `references/scales.md` 的当前分档要求执行。
  - `specs/*/spec.md` 或等价 functional spec：描述用户可观察行为和验收场景。
  - `tasks.md`：按可执行切片拆分任务，并给每项写可验证验收标准。
 - 运行 cross-artifact 对齐检查：proposal → 设计产物 → specs → tasks。
 - 如果发现 gap，先修正 OpenSpec，再进入 commit。
 ## audit 内置协议
 - 用 5 句话以内说明模块链路、数据所有权、跨模块依赖、架构风险和是否需要回写 OpenSpec。
 - 如果风险影响实现，修正设计产物或 `tasks.md`。
 - 将结论写入 `decisions.md`。
 ## openspec apply 内置协议
 - 只依据 Committed OpenSpec 的 specs/tasks 实现；devflow 只作上下文参考。
 - 开始前检查 `.committed` 文件；缺失则返回 commit。
 - 如触发 pre-apply checkpoint，先阅读参考实现、grep 项目基础设施模式，并把技术栈清单写入 `decisions.md`。
 - 按 tasks 的纵向切片实现、验证并更新任务状态。
 - 发现冲突时按三类处理：OpenSpec 不准则修 OpenSpec，代码偏离则修代码，不确定则暂停等用户确认。
 ## openspec archive 内置协议
 - 不删除或移动 OpenSpec change；只标记归档准备状态。
 - 完成 devflow 回填、更新 `devflow/index.md`、创建 `.archive-ready`。
 - 向用户汇报已创建文件、验证分类、剩余风险，并询问是否需要真实 OpenSpec archive。
 - 如果外部 archive 能力仍不可用，在 `acceptance.md` 标记 `accepted-unarchived`。

 ### Pre-apply Checkpoint
 **触发条件**：当 OpenSpec 涉及以下任一情况时必须执行
 - design 或 tasks 中提到"参考 XXX 实现"
 - 需要调用项目现有基础设施（MQ/统一请求结构/工具类等）
 - 技术栈不熟悉或第一次在该项目实现类似功能
 **执行步骤**：
 1. **阅读所有参考实现**
   - 从 OpenSpec design 或 tasks 中定位参考实现文件
   - 如果路径不明确，通过 Grep 搜索关键类名或模式
   - 理解关键逻辑，提取可复用代码片段和模式
 2. **Grep 关键技术栈**
   - 请求/响应结构模式（如 `RequestMsg`、`ResponseMsg`、DTO 规范）
   - 消息队列模式（如 `@KafkaListener`、`@YkMsg`、发送模板）
   - 统一工具类（如 `XxxUtil`、`XxxHelper`、加密/验签工具）
   - 异常处理和日志记录标准
 3. **形成技术栈清单并写入 decisions.md**
   - 项目使用的请求/响应结构标准
   - MQ 消息定义和发送标准
   - Consumer 标准位置和写法
   - 加密/验签/工具类的标准用法
   - 识别需要新建的工具类或基础设施
 **输出要求**：
 - 技术栈清单已写入 `decisions.md` 的 "Pre-apply Research" 章节。
 - 已列出所有参考实现的文件路径。
 - 已识别需要新建的工具类/基础设施。
 **按风险执行**：执行深度按 `references/scales.md` 的当前分档和实现风险决定；退出判断以清单是否足以指导实现为准。
 ### 实现过程
 - 优先调用 `openspec-apply-change`。
 - 执行依据是 OpenSpec specs/tasks；devflow 只能作为上下文参考。
 - 按 OpenSpec tasks 的纵向切片实现。
 - **分步实现**：建议按 Controller → Service → MQ/异步组件 → Consumer/下游 顺序，每完成一层验证后再继续。
 - 进入实现前先汇报本阶段的 capability 来源、当前 task 进度和本轮要推进的切片；否则 apply 不算真正开始。
 - **首模块完成后对齐检查**：完成第一个接口/模块后，对比 OpenSpec design/tasks，标记"已完成/TODO"；核心功能（加密/验签/核心业务逻辑）不允许空实现或纯 TODO 注释。
 - 当用户质疑、用户要求修改、代码检查、测试失败或运行行为与 OpenSpec 冲突时，做三类判断：
  - OpenSpec 不准（规格遗漏、边界未覆盖、验收口径缺失）→ 暂停 apply，修正 OpenSpec 后重新提交。
  - 代码偏离（实现没按 OpenSpec 做）→ 修正代码，不改 OpenSpec。
  - 不确定根因、涉及设计方向、用户改变目标或范围 → 暂停并等待用户确认。
 - 判断结果、证据、用户确认和 OpenSpec 回写状态必须记录到 `decisions.md`。
 - **快速失败**：连续返工 ≥ 2 次时，暂停并重新执行 pre-apply checkpoint 或向用户汇报。
 - 当用户要求、行为复杂或回归风险高时使用 TDD。
 - 当测试失败、行为意外或原因不确定时使用 diagnose。
 - 如果 diagnose 发现根因是 OpenSpec 不准确，先修正 OpenSpec，再继续 apply。
 - 修改文件前遵守仓库指令，例如 `AGENTS.md`。

 本文件是 `micro / standard / complex` 的唯一规则源。其它文件只引用本文件，不重复定义分档细节。
 ## standard 基准
 standard 是默认分档，适用于普通功能、明确但有一定实现范围的变更。
 - 用户可见 checkpoint：Discover → Commit → Apply → Archive。
 - OpenSpec 产物：`proposal.md`、独立 `design.md`、`specs/`、`tasks.md`。
 - grill：解决术语、边界、验收三个维度的高价值问题。
 - commit gate：检查 proposal、design、specs、tasks 的完整性和一致性。
 - devflow 档案：`brief.md`、`evidence.md`、`decisions.md`、`acceptance.md`。
 ## micro 覆盖
 micro 适用于小改动、低风险、需求明确的变更。micro 是 standard 的减法，不是跳过流程。
 - checkpoint 可合并：Discover + Commit 可在无阻塞时合并汇报。
 - micro 内部流程压缩为：clarify+context 合并 checkpoint → 轻量 propose → grill → specify+commit 合并 checkpoint。
 - context 保留最小收集：至少检查 glossary 和相关 ADR。
 - grill 保留最小澄清：至少解决一个高价值问题，并记录术语、边界、验收三类是否明确；不明确项必须补问或标记风险。
 - OpenSpec 仍需要 `proposal.md`、`specs/`、`tasks.md`。
 - `design.md` 可不独立创建；允许在 `proposal.md` 或 `tasks.md` 中写等价设计小节。
 - `specs/` 和 `tasks.md` 可轻量，但必须表达可观察行为和可执行任务。
 - commit gate 仍必须通过，并创建 `.committed`。
 - devflow 档案至少包含 `brief.md`、`decisions.md`、`acceptance.md`；证据少时可并入 `brief.md` 或 `decisions.md`。
 - apply 仍只能依据 Committed OpenSpec。
 - archive 仍要轻量回填 devflow，并询问是否归档 OpenSpec。
 micro 不适用于接口影响不清、跨团队消费者、迁移/回滚、复杂状态机、长期架构决策或需求边界不清的变更；遇到这些情况应升级为 standard 或 complex。
 ## complex 增量
 complex 适用于高风险、跨模块、需求不清、多人协作或长期架构影响明显的变更。complex 是 standard 的加法。
 - 需要更完整的 Discover：增加需求澄清、证据查证、范围确认和风险接受。
 - checkpoint 内可补充关键内部阶段结果，但不要把内部阶段名当作用户操作入口。
 - 按需创建 `prd.md`、`research.md`、`alignment.md`、接口文档、ADR 或 compound knowledge。
 - 接口影响、迁移、灰度、回滚、兼容性和消费者边界必须显式记录。
 - audit 需要覆盖模块链路、数据所有权、生命周期、耦合风险和 ADR 冲突。

 # Test-Driven Development
 ## Philosophy
 **Core principle**: Tests should verify behavior through public interfaces, not implementation details. Code can change entirely; tests shouldn't.
 **Good tests** are integration-style: they exercise real code paths through public APIs. They describe _what_ the system does, not _how_ it does it. A good test reads like a specification - "user can checkout with valid cart" tells you exactly what capability exists. These tests survive refactors because they don't care about internal structure.
 **Bad tests** are coupled to implementation. They mock internal collaborators, test private methods, or verify through external means (like querying a database directly instead of using the interface). The warning sign: your test breaks when you refactor, but behavior hasn't changed. If you rename an internal function and tests fail, those tests were testing implementation, not behavior.
 See [tests.md](tests.md) for examples and [mocking.md](mocking.md) for mocking guidelines.
 ## Anti-Pattern: Horizontal Slices
 **DO NOT write all tests first, then all implementation.** This is "horizontal slicing" - treating RED as "write all tests" and GREEN as "write all code."
 This produces **crap tests**:
 - Tests written in bulk test _imagined_ behavior, not _actual_ behavior
 - You end up testing the _shape_ of things (data structures, function signatures) rather than user-facing behavior
 - Tests become insensitive to real changes - they pass when behavior breaks, fail when behavior is fine
 - You outrun your headlights, committing to test structure before understanding the implementation
 **Correct approach**: Vertical slices via tracer bullets. One test → one implementation → repeat. Each test responds to what you learned from the previous cycle. Because you just wrote the code, you know exactly what behavior matters and how to verify it.
 ```
 WRONG (horizontal):
  RED:   test1, test2, test3, test4, test5
  GREEN: impl1, impl2, impl3, impl4, impl5
 RIGHT (vertical):
  RED→GREEN: test1→impl1
  RED→GREEN: test2→impl2
  RED→GREEN: test3→impl3
  ...
 ```
 ## Workflow
 ### 1. Planning
 When exploring the codebase, use the project's domain glossary so that test names and interface vocabulary match the project's language, and respect ADRs in the area you're touching.
 Before writing any code:
 - [ ] Confirm with user what interface changes are needed
 - [ ] Confirm with user which behaviors to test (prioritize)
 - [ ] Identify opportunities for [deep modules](deep-modules.md) (small interface, deep implementation)
 - [ ] Design interfaces for [testability](interface-design.md)
 - [ ] List the behaviors to test (not implementation steps)
 - [ ] Get user approval on the plan
 Ask: "What should the public interface look like? Which behaviors are most important to test?"
 **You can't test everything.** Confirm with the user exactly which behaviors matter most. Focus testing effort on critical paths and complex logic, not every possible edge case.
 ### 2. Tracer Bullet
 Write ONE test that confirms ONE thing about the system:
 ```
 RED:   Write test for first behavior → test fails
 GREEN: Write minimal code to pass → test passes
 ```
 This is your tracer bullet - proves the path works end-to-end.
 ### 3. Incremental Loop
 For each remaining behavior:
 ```
 RED:   Write next test → fails
 GREEN: Minimal code to pass → passes
 ```
 Rules:
 - One test at a time
 - Only enough code to pass current test
 - Don't anticipate future tests
 - Keep tests focused on observable behavior
 ### 4. Refactor
 After all tests pass, look for [refactor candidates](refactoring.md):
 - [ ] Extract duplication
 - [ ] Deepen modules (move complexity behind simple interfaces)
 - [ ] Apply SOLID principles where natural
 - [ ] Consider what new code reveals about existing code
 - [ ] Run tests after each refactor step
 **Never refactor while RED.** Get to GREEN first.
 ## Checklist Per Cycle
 ```
 [ ] Test describes behavior, not implementation
 [ ] Test uses public interface only
 [ ] Test would survive internal refactor
 [ ] Code is minimal for this test
 [ ] No speculative features added
 ```

 # Deep Modules

 **Deep module** = small interface + lots of implementation
 ```

 When designing interfaces, ask:
 - Can I reduce the number of methods?
 - Can I simplify the parameters?
 - Can I hide more complexity inside?

 # Interface Design for Testability
 Good interfaces make testing natural:
 1. **Accept dependencies, don't create them**

   // Testable
   function processOrder(order, paymentGateway) {}
   // Hard to test

 2. **Return results, don't produce side effects**

   // Testable
   function calculateDiscount(cart): Discount {}
   // Hard to test
   function applyDiscount(cart): void {
     cart.total -= discount;

   - Fewer params = simpler test setup

 # When to Mock
 Mock at **system boundaries** only:
 - External APIs (payment, email, etc.)
 - Databases (sometimes - prefer test DB)
 - Time/randomness
 - File system (sometimes)
 Don't mock:
 - Your own classes/modules
 - Internal collaborators
 - Anything you control
 ## Designing for Mockability
 At system boundaries, design interfaces that are easy to mock:
 **1. Use dependency injection**
 Pass external dependencies in rather than creating them internally:
 ```typescript
 // Easy to mock
 function processPayment(order, paymentClient) {
  return paymentClient.charge(order.total);
 }
 // Hard to mock
 function processPayment(order) {
  const client = new StripeClient(process.env.STRIPE_KEY);
  return client.charge(order.total);
 }
 ```
 **2. Prefer SDK-style interfaces over generic fetchers**
 Create specific functions for each external operation instead of one generic function with conditional logic:
 ```typescript
 // GOOD: Each function is independently mockable
 const api = {
  getUser: (id) => fetch(`/users/${id}`),
  getOrders: (userId) => fetch(`/users/${userId}/orders`),
  createOrder: (data) => fetch('/orders', { method: 'POST', body: data }),
 };
 // BAD: Mocking requires conditional logic inside the mock
 const api = {
  fetch: (endpoint, options) => fetch(endpoint, options),
 };
 ```
 The SDK approach means:
 - Each mock returns one specific shape
 - No conditional logic in test setup
 - Easier to see which endpoints a test exercises
 - Type safety per endpoint

 # Good and Bad Tests
 ## Good Tests
 **Integration-style**: Test through real interfaces, not mocks of internal parts.
 ```typescript
 // GOOD: Tests observable behavior
 test("user can checkout with valid cart", async () => {
  const cart = createCart();
  cart.add(product);
  const result = await checkout(cart, paymentMethod);
  expect(result.status).toBe("confirmed");
 });
 ```
 Characteristics:
 - Tests behavior users/callers care about
 - Uses public API only
 - Survives internal refactors
 - Describes WHAT, not HOW
 - One logical assertion per test
 ## Bad Tests
 **Implementation-detail tests**: Coupled to internal structure.
 ```typescript
 // BAD: Tests implementation details
 test("checkout calls paymentService.process", async () => {
  const mockPayment = jest.mock(paymentService);
  await checkout(cart, payment);
  expect(mockPayment.process).toHaveBeenCalledWith(cart.total);
 });
 ```
 Red flags:
 - Mocking internal collaborators
 - Testing private methods
 - Asserting on call counts/order
 - Test breaks when refactoring without behavior change
 - Test name describes HOW not WHAT
 - Verifying through external means instead of interface
 ```typescript
 // BAD: Bypasses interface to verify
 test("createUser saves to database", async () => {
  await createUser({ name: "Alice" });
  const row = await db.query("SELECT * FROM users WHERE name = ?", ["Alice"]);
  expect(row).toBeDefined();
 });
 // GOOD: Verifies through interface

 description: Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.
 ---
 This skill takes the current conversation context and codebase understanding and produces a PRD. Do NOT interview the user — just synthesize what you already know.
 The issue tracker and triage label vocabulary should have been provided to you — run `/setup-matt-pocock-skills` if not.
 ## Process
 1. Explore the repo to understand the current state of the codebase, if you haven't already. Use the project's domain glossary vocabulary throughout the PRD, and respect any ADRs in the area you're touching.
 2. Sketch out the major modules you will need to build or modify to complete the implementation. Actively look for opportunities to extract deep modules that can be tested in isolation.
 A deep module (as opposed to a shallow module) is one which encapsulates a lot of functionality in a simple, testable interface which rarely changes.
 Check with the user that these modules match their expectations. Check with the user which modules they want tests written for.
 3. Write the PRD using the template below, then publish it to the project issue tracker. Apply the `ready-for-agent` triage label - no need for additional triage.
 <prd-template>
 ## Problem Statement
 The problem that the user is facing, from the user's perspective.
 ## Solution
 The solution to the problem, from the user's perspective.
 ## User Stories
 A LONG, numbered list of user stories. Each user story should be in the format of:
 1. As an <actor>, I want a <feature>, so that <benefit>
 <user-story-example>
 1. As a mobile bank customer, I want to see balance on my accounts, so that I can make better informed decisions about my spending
 </user-story-example>
 This list of user stories should be extremely extensive and cover all aspects of the feature.
 ## Implementation Decisions
 A list of implementation decisions that were made. This can include:
 - The modules that will be built/modified
 - The interfaces of those modules that will be modified
 - Technical clarifications from the developer
 - Architectural decisions
 - Schema changes
 - API contracts
 - Specific interactions
 Do NOT include specific file paths or code snippets. They may end up being outdated very quickly.
 Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it within the relevant decision and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.
 ## Testing Decisions
 A list of testing decisions that were made. Include:
 - A description of what makes a good test (only test external behavior, not implementation details)
 - Which modules will be tested
 - Prior art for the tests (i.e. similar types of tests in the codebase)
 ## Out of Scope
 A description of the things that are out of scope for this PRD.
 ## Further Notes
 Any further notes about the feature.

 # Frontend Design — Complete Guidance
 This document provides a comprehensive framework for creating visually distinctive, non-templated UI designs. Here's the full breakdown:
 ## Foundational Approach
 Act as the design lead for a studio known for unique client identities — the client has already turned down template-like proposals. Every choice about palette, typography, and layout must be specific to the brief, including "one real aesthetic risk you can justify."
 ## Grounding in Subject Matter
 If the brief is vague about the product or subject, pin it down yourself: name the subject, its audience, and the page's single job. Draw inspiration from "the subject's own world, its materials, instruments, artifacts, and vernacular." Use any known context about the human's preferences or past designs as hints.
 ## Design Principles
 - **Hero as thesis**: Open with "the most characteristic thing in the subject's world" — avoid default choices like a big number with a small label and gradient accent unless truly optimal.
 - **Typography**: Pair display and body faces deliberately, not from your usual repertoire. Set a clear type scale with intentional weights, widths, and spacing. "Make the type treatment itself a memorable part of the design."
 - **Structure as information**: Numbering, eyebrows, dividers must encode something true about the content. Question whether numbered markers (01/02/03) actually make sense before using them — only appropriate for real sequences.
 - **Motion**: Consider where animation serves the subject. "An orchestrated moment usually lands harder than scattered effects." Sometimes less is better to avoid an AI-generated feel.
 - **Complexity**: Match execution to the vision — maximalist needs elaborate execution, minimal needs precision.
 - **Content**: Come up with copy if the brief lacks it. Poor copy makes a design feel as templated as poor layout.
 ## AI-Generated Design Traps
 Three common AI-default looks to watch for: (1) warm cream background (~#F4F1EA) with serif display and terracotta accent; (2) near-black with bright acid-green or vermilion; (3) broadsheet layout with hairline rules, zero border-radius, and dense columns. "All three are legitimate for some briefs, but they are defaults rather than choices." Where the brief leaves an axis free, don't spend that freedom on a default.
 ## Two-Pass Process
 **Pass 1 — Plan**: Create a compact token system:
 1. **Color**: 4–6 named hex values
 2. **Type**: Characterful display face (used with restraint), complementary body face, utility face for captions/data
 3. **Layout**: One-sentence prose descriptions + ASCII wireframes
 4. **Signature**: The single unique element the page will be remembered by
 Review the plan against the brief. If any part reads like what you'd produce for any similar page, revise it. Only then write code.
 **Pass 2 — Build**: Follow the revised plan exactly. Watch for CSS selector specificity conflicts (e.g., `.section` and `.cta` fighting over padding/margins). Do most planning internally, only sharing ideas when confident.
 ## Restraint & Self-Critique
 "Spend your boldness in one place" — let the signature element be the one memorable thing; keep everything else quiet. "Not taking a risk can be a risk itself!" Build responsively down to mobile, with visible keyboard focus and reduced motion respected. Critique as you build. Follow Chanel's advice: before finishing, remove one accessory. Jot notes about what you've tried to avoid repeating yourself.
 ## Writing in Design
 Words exist to make the design understandable and usable — they're "design material, not decoration." Write from the end user's perspective, naming things by what people control and recognize, never by how the system is built.
 - Use active voice as default
 - A control should say exactly what happens: "Save changes," not "Submit"
 - Maintain consistent vocabulary throughout flows (button says "Publish," toast says "Published")
 - Treat errors as guidance, not mood — explain what went wrong and how to fix it
 - Empty screens are invitations to act
 - Keep the register conversational: "plain verbs, sentence case, no filler"
 - Let each element do exactly one job — "a label labels, an example demonstrates"

 Implement tasks from an OpenSpec change.
 **Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
 **Steps**
 1. **Select the change**
   If a name is provided, use it. Otherwise:
   - Infer from conversation context if the user mentioned a change
   - Auto-select if only one active change exists
   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
 2. **Check status to understand the schema**
   ```bash
   openspec status --change "<name>" --json
   ```
   Parse the JSON to understand:
   - `schemaName`: The workflow being used (e.g., "spec-driven")
   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
 3. **Get apply instructions**
   ```bash
   openspec instructions apply --change "<name>" --json
   ```
   This returns:
   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
   - Progress (total, complete, remaining)
   - Task list with status
   - Dynamic instruction based on current state
   **Handle states:**
   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
   - If `state: "all_done"`: congratulate, suggest archive
   - Otherwise: proceed to implementation
 4. **Read context files**
   Read every file path listed under `contextFiles` from the apply instructions output.
   The files depend on the schema being used:
   - **spec-driven**: proposal, specs, design, tasks
   - Other schemas: follow the contextFiles from CLI output
 5. **Show current progress**
   Display:
   - Schema being used
   - Progress: "N/M tasks complete"
   - Remaining tasks overview
   - Dynamic instruction from CLI
 6. **Implement tasks (loop until done or blocked)**
   For each pending task:
   - Show which task is being worked on
   - Make the code changes required
   - Keep changes minimal and focused
   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
   - Continue to next task
   **Pause if:**
   - Task is unclear → ask for clarification
   - Implementation reveals a design issue → suggest updating artifacts
   - Error or blocker encountered → report and wait for guidance
   - User interrupts
 7. **On completion or pause, show status**
   Display:
   - Tasks completed this session
   - Overall progress: "N/M tasks complete"
   - If all done: suggest archive
   - If paused: explain why and wait for guidance
 **Output During Implementation**
 ```
 ## Implementing: <change-name> (schema: <schema-name>)

 **Options:**
 1. <option 1>
 2. <option 2>
 3. Other approach
 What would you like to do?
 ```
 **Guardrails**
 - Keep going through tasks until done or blocked
 - Always read context files before starting (from the apply instructions output)
 - If task is ambiguous, pause and ask before implementing
 - If implementation reveals issues, pause and suggest artifact updates
 - Keep code changes minimal and scoped to each task
 - Update task checkbox immediately after completing each task
 - Pause on errors, blockers, or unclear requirements - don't guess
 - Use contextFiles from CLI output, don't assume specific file names
 **Fluid Workflow Integration**
 This skill supports the "actions on a change" model:
 - **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
 - **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

   **If no tasks file exists:** Proceed without task-related warning.
 4. **Assess delta spec sync state**
   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
   **If delta specs exist:**
   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
   - Determine what changes would be applied (adds, modifications, removals, renames)
   - Show a combined summary before prompting
   **Prompt options:**
   - If changes needed: "Sync now (recommended)", "Archive without syncing"
   - If already synced: "Archive now", "Sync anyway", "Cancel"
   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
 5. **Perform the archive**
   Create the archive directory if it doesn't exist:
   ```bash
   mkdir -p openspec/changes/archive
   ```
   Generate target name using current date: `YYYY-MM-DD-<change-name>`
   **Check if target already exists:**
   - If yes: Fail with error, suggest renaming existing archive or using different date
   - If no: Move the change directory to archive
   ```bash
   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
   ```
 6. **Display summary**
   Show archive completion summary including:
   - Change name
   - Schema that was used
   - Archive location
   - Whether specs were synced (if applicable)
   - Note about any warnings (incomplete artifacts/tasks)
 **Output On Success**
 ```
 ## Archive Complete
 **Change:** <change-name>
 **Schema:** <schema-name>
 **Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
 **Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
 All artifacts complete. All tasks complete.
 ```
 **Guardrails**
 - Always prompt for change selection if not provided
 - Use artifact graph (openspec status --json) for completion checking
 - Don't block archive on warnings - just inform and confirm
 - Preserve .openspec.yaml when moving to archive (it moves with the directory)
 - Show clear summary of what happened
 - If sync is requested, use openspec-sync-specs approach (agent-driven)
 - If delta specs exist, always run the sync assessment and show the combined summary before prompting

 Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
 **IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
 **This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
 ---
 ## The Stance
 - **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
 - **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
 - **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
 - **Adaptive** - Follow interesting threads, pivot when new information emerges
 - **Patient** - Don't rush to conclusions, let the shape of the problem emerge
 - **Grounded** - Explore the actual codebase when relevant, don't just theorize
 ---
 ## What You Might Do
 Depending on what the user brings, you might:
 **Explore the problem space**
 - Ask clarifying questions that emerge from what they said
 - Challenge assumptions
 - Reframe the problem
 - Find analogies
 **Investigate the codebase**
 - Map existing architecture relevant to the discussion
 - Find integration points
 - Identify patterns already in use
 - Surface hidden complexity
 **Compare options**
 - Brainstorm multiple approaches
 - Build comparison tables
 - Sketch tradeoffs
 - Recommend a path (if asked)
 **Visualize**

 ```
 **Surface risks and unknowns**
 - Identify what could go wrong
 - Find gaps in understanding
 - Suggest spikes or investigations
 ---
 ## OpenSpec Awareness
 You have full context of the OpenSpec system. Use it naturally, don't force it.
 ### Check for context
 At the start, quickly check what exists:
 ```bash
 openspec list --json
 ```
 This tells you:
 - If there are active changes
 - Their names, schemas, and status
 - What the user might be working on
 ### When no change exists
 Think freely. When insights crystallize, you might offer:
 - "This feels solid enough to start a change. Want me to create a proposal?"
 - Or keep exploring - no pressure to formalize
 ### When a change exists
 If the user mentions a change or you detect one is relevant:
 1. **Read existing artifacts for context**
   - `openspec/changes/<name>/proposal.md`
   - `openspec/changes/<name>/design.md`
   - `openspec/changes/<name>/tasks.md`
   - etc.
 2. **Reference them naturally in conversation**
   - "Your design mentions using Redis, but we just realized SQLite fits better..."
   - "The proposal scopes this to premium users, but we're now thinking everyone..."
 3. **Offer to capture when decisions are made**
    | Insight Type               | Where to Capture               |
    |----------------------------|--------------------------------|
    | New requirement discovered | `specs/<capability>/spec.md` |
    | Requirement changed        | `specs/<capability>/spec.md` |
    | Design decision made       | `design.md`                  |
    | Scope changed              | `proposal.md`                |
    | New work identified        | `tasks.md`                   |
    | Assumption invalidated     | Relevant artifact              |
   Example offers:
   - "That's a design decision. Capture it in design.md?"
   - "This is a new requirement. Add it to specs?"
   - "This changes scope. Update the proposal?"
 4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
 ---
 ## What You Don't Have To Do
 - Follow a script
 - Ask the same questions every time
 - Produce a specific artifact
 - Reach a conclusion
 - Stay on topic if a tangent is valuable
 - Be brief (this is thinking time)
 ---

 ## Ending Discovery
 There's no required ending. Discovery might:
 - **Flow into a proposal**: "Ready to start? I can create a change proposal."
 - **Result in artifact updates**: "Updated design.md with these decisions"
 - **Just provide clarity**: User has what they need, moves on
 - **Continue later**: "We can pick this up anytime"
 When it feels like things are crystallizing, you might summarize:
 ```
 ## What We Figured Out
 **The problem**: [crystallized understanding]
 **The approach**: [if one emerged]
 **Open questions**: [if any remain]
 **Next steps** (if ready):
 - Create a change proposal
 - Keep exploring: just keep talking
 ```
 But this summary is optional. Sometimes the thinking IS the value.
 ---
 ## Guardrails
 - **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
 - **Don't fake understanding** - If something is unclear, dig deeper
 - **Don't rush** - Discovery is thinking time, not task time
 - **Don't force structure** - Let patterns emerge naturally
 - **Don't auto-capture** - Offer to save insights, don't just do it
 - **Do visualize** - A good diagram is worth many paragraphs
 - **Do explore the codebase** - Ground discussions in reality
 - **Do question assumptions** - Including the user's and your own

 Propose a new change - create the change and generate all artifacts in one step.
 I'll create a change with artifacts:
 - proposal.md (what & why)
 - design.md (how)
 - tasks.md (implementation steps)
 When ready to implement, run /opsx:apply
 ---
 **Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
 **Steps**
 1. **If no clear input provided, ask what they want to build**
   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
   > "What change do you want to work on? Describe what you want to build or fix."
   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
 2. **Create the change directory**
   ```bash
   openspec new change "<name>"
   ```
   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
 3. **Get the artifact build order**
   ```bash
   openspec status --change "<name>" --json
   ```
   Parse the JSON to get:
   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
   - `artifacts`: list of all artifacts with their status and dependencies
 4. **Create artifacts in sequence until apply-ready**
   Use the **TodoWrite tool** to track progress through the artifacts.
   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
   a. **For each artifact that is `ready` (dependencies satisfied)**:
      - Get instructions:
        ```bash
        openspec instructions <artifact-id> --change "<name>" --json
        ```
      - The instructions JSON includes:
        - `context`: Project background (constraints for you - do NOT include in output)
        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
        - `template`: The structure to use for your output file
        - `instruction`: Schema-specific guidance for this artifact type
        - `outputPath`: Where to write the artifact
        - `dependencies`: Completed artifacts to read for context
      - Read any completed dependency files for context
      - Create the artifact file using `template` as the structure
      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
      - Show brief progress: "Created <artifact-id>"
   b. **Continue until all `applyRequires` artifacts are complete**
      - After creating each artifact, re-run `openspec status --change "<name>" --json`
      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
      - Stop when all `applyRequires` artifacts are done
   c. **If an artifact requires user input** (unclear context):
      - Use **AskUserQuestion tool** to clarify
      - Then continue with creation
 5. **Show final status**
   ```bash
   openspec status --change "<name>"
   ```
 **Output**
 After completing all artifacts, summarize:
 - Change name and location
 - List of artifacts created with brief descriptions
 - What's ready: "All artifacts created! Ready for implementation."
 - Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
 **Artifact Creation Guidelines**
 - Follow the `instruction` field from `openspec instructions` for each artifact type
 - The schema defines what each artifact should contain - follow it
 - Read dependency artifacts for context before creating new ones
 - Use `template` as the structure for your output file - fill in its sections
 - **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
  - These guide what you write, but should never appear in the output
 **Guardrails**
 - Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
 - Always read dependency artifacts before creating a new one
 - If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
 - If a change with that name already exists, ask if user wants to continue it or create a new one
 - Verify each artifact file exists after writing before proceeding to next

 name: sm-flow
 description: OpenSpec-first 工程流程 harness。仅在用户显式调用 /sm-flow、/sm-flow explore、/sm-flow apply、/sm-flow archive，或明确要求使用 sm-flow 流程时使用；不要根据需求类型自动触发。
 ---
 # SM Flow
 SM Flow 是一个**协议层 harness**——编排 OpenSpec 的完整生命周期。它通过阶段、门控、人类对齐和长期记忆，约束 agent 以正确的顺序、条件和标准使用 OpenSpec。
 sm-flow 会自动维护 `devflow/` 目录作为项目长期记忆。用户不需要手动管理它，sm-flow 会在流程中自动读取和回填。
 ## 触发规则
 只在用户显式调用时使用 sm-flow：
 - 用户输入 `/sm-flow`、`/sm-flow explore`、`/sm-flow apply`、`/sm-flow archive`。
 - 用户用自然语言明确要求"使用 sm-flow"、"走 sm-flow 流程"或等价表达。
 不要根据需求类型自动触发 sm-flow。即使任务涉及 OpenSpec、跨模块、接口契约、需求澄清或 devflow 归档，只要用户没有显式要求 sm-flow，就按普通工程任务处理。
 ## 四层架构
 ```
 sm-flow        → 编排层（harness）：阶段、门控、产物约束、人类对齐
  OpenSpec     → 执行引擎：propose/apply/archive 的能力提供方
    devflow/   → 记忆层：为编排层提供上下文，接收执行结果的回填
      code     → 实现结果：apply 的产出
 ```
 - OpenSpec 是唯一执行真理源：apply 阶段只能基于 OpenSpec 执行，不能绕过 OpenSpec 直接写代码。
 - devflow 是上下文真理源：术语、历史决策、验收记录来自 devflow，用于增强 OpenSpec，不替代 OpenSpec。
 - 如果 devflow 和 OpenSpec 冲突，先汇报冲突、让用户确认、修正 OpenSpec，再继续执行。
 - propose 阶段产出的 OpenSpec 默认为 **Draft OpenSpec**：它是澄清和审计对象，不是 apply 的执行许可。
 - 只有通过 commit 检查后的 OpenSpec 才是 **Committed OpenSpec**；apply 只能执行 Committed OpenSpec。
 ## 核心规则
 以下 6 条是硬约束，违反即流程失败。其余约束按阶段定义在 `references/phase-contracts.md`。
 1. **OpenSpec 是唯一执行真理源**。apply 阶段必须读取 Committed OpenSpec 文件作为执行依据；对话中的描述不等于产物。Draft OpenSpec 是讨论对象，不是执行许可。
 2. **不得跳过 context**。生成 OpenSpec 前，必须先读取相关 devflow 上下文（glossary、ADR、历史项目）。
 3. **不得跳过 grill**。必须按 `references/scales.md` 的当前分档要求完成澄清或验证。
 4. **不得跳过 commit**。进入 apply 前，Draft OpenSpec 必须通过 commit 检查成为 Committed OpenSpec。
 5. **冲突必须先分类再处理**。OpenSpec 不准（规格遗漏）→ 修正 OpenSpec；代码偏离（实现偏差）→ 修正代码；不确定或涉及设计方向 → 暂停并等待用户确认。
 6. **能力来源必须显式声明**。每个阶段先声明使用外部子 skill / OpenSpec CLI / sm-flow 内置协议；外部能力不可用时可使用 `references/fallbacks.md` 的内置协议，但必须标注为 fallback。若外部能力和内置协议都不可用，流程失败。
 每个阶段的过程约束（question pool、one-at-a-time、cross-artifact 对齐、冲突回写等）和质量约束（可观测产出要求）见 `references/phase-contracts.md` 中对应阶段的退出条件和 checkpoint。
 ## 用户命令
 | 命令 | 用户意图 | harness 内部行为 |
 |---|---|---|
 | `/sm-flow` | 完整流程 | clarify → context → propose → grill → specify → audit → commit → apply → archive |
 | `/sm-flow explore` | 先想想 | 带上下文的探索模式 |
 | `/sm-flow apply` | 只执行 | 检查 commit gate → apply |
 | `/sm-flow archive` | 收尾 | 回填 devflow + 归档确认 |
 用户也可以用自然语言指定从某个阶段继续，例如"ops-message-support 的 grill 已经做完了，继续"。harness 识别意图后，自动补做最小前置检查，然后从指定阶段继续。
 ## 可见 Checkpoint
 内部阶段不是用户 API。对用户汇报进度时，默认只暴露 4 个 checkpoint：
 | Checkpoint | 覆盖内部阶段 | 用户可见含义 |
 |---|---|---|
 | Discover | clarify + context + propose + grill | 澄清目标、读取 devflow、形成轻量 proposal、解决关键问题 |
 | Commit | specify + audit + commit | 补全 OpenSpec、做架构/产物对齐、生成 Committed OpenSpec |
 | Apply | apply | 基于 Committed OpenSpec 实现和验证 |
 | Archive | archive | 回填 devflow、汇报验收、询问是否归档 OpenSpec |
 除非用户要求看细节，进度汇报、暂停点和恢复提示应使用 checkpoint 名称，而不是逐个暴露 9 个内部阶段。内部阶段仍按顺序执行，并以 `references/phase-contracts.md` 为准。
 ## 首次加载
 执行前只读取当前任务需要的 reference 文件：
 - 需要执行阶段时，先读取 `references/phase-contracts.md`；如果当前阶段涉及接口影响分级、分档、启动规则、快速模式或完成标准，再补读 `references/operating-rules.md`；如果外部 OpenSpec 能力或子 skill 不可用，再补读 `references/fallbacks.md`。
 - 判断或执行 `micro / standard / complex` 分档时，读取 `references/scales.md`；其它文件不得重复定义分档细节。
 - 当 checkpoint / gate / fallback / Draft / Committed 等术语含义不清，或需要统一对用户说明时，读取 `references/glossary.md`。
 - 创建或更新 PRD、ADR、验收报告、词汇表、复合知识文档时，读取 `references/templates.md`。
 - archive 阶段或需要从 OpenSpec 提取产物时，读取 `references/archive-rules.md`。
 ## 内部阶段
 9 个内部阶段，按执行顺序：
 1. clarify — 入口澄清：接收初始需求，澄清到可生成轻量 proposal。
 2. context — 上下文收集：读取 devflow 的 glossary、ADR、历史项目、compound knowledge。
 3. propose — 轻量 propose：只生成 proposal.md，不调用 openspec-propose。
 4. grill — 人类对齐澄清：evidence-driven 查证 + user-interview one-at-a-time，回写 proposal。
 5. specify — 细化 + 对齐：基于已稳定的 proposal 补全 design/specs/tasks，做 cross-artifact 对齐。
 6. audit — 架构审计：审计结果如果影响实现，回写 OpenSpec design/tasks。
 7. commit — Commit OpenSpec：检查 Draft OpenSpec 是否达到可执行状态，提交为 Committed OpenSpec。
 8. apply — OpenSpec 执行：基于 Committed OpenSpec 实现代码。
 9. archive — 回填 + 归档：从 OpenSpec 产物和 decisions.md 提炼长期档案，询问是否归档。
 每个阶段的进入条件、动作、输出和退出标准见 `references/phase-contracts.md`。
 关键阶段的完成判断也以 `references/phase-contracts.md` 为准；如果缺少显式 checkpoint 或能力来源声明，该阶段不得视为已完成。

 # 归档规则
 archive 阶段的目标是把 OpenSpec 产物、实现结果和过程日志转化为持久、可读、可复用的项目记忆。sm-flow 在 clarify → apply 期间只维护 `decisions.md` 作为过程日志，archive 阶段从中提取完整 devflow 档案。
 ## Archive 强制执行顺序
 Archive 阶段必须按以下顺序执行，不得跳过或重排：
 ### Step 1: 创建 devflow 档案（必需）
 - [ ] 创建 `devflow/projects/YYYY-MM-DD-{slug}/brief.md`
      （从 proposal.md 提取：背景、目标、范围、非目标）
 - [ ] 按 `references/scales.md` 的当前分档决定是否创建 `devflow/projects/YYYY-MM-DD-{slug}/evidence.md`
      （创建时从 decisions.md 提取 evidence-driven 记录）
 - [ ] 创建 `devflow/projects/YYYY-MM-DD-{slug}/decisions.md`
      （整理为最终版：关键决策、权衡、风险）
 - [ ] 创建 `devflow/projects/YYYY-MM-DD-{slug}/acceptance.md`
      （记录：静态验证、脚本验证、浏览器/人工验证、未验证）
 ### Step 2: 更新索引（必需）
 - [ ] 在 `devflow/index.md` 末尾追加或更新一行：
      `| YYYY-MM-DD | slug | 领域 | 关键词 | openspec/changes/xxx | {status} |`
 ### Step 3: 标记 OpenSpec（必需）
 - [ ] 创建 `openspec/changes/{slug}/.archive-ready` 文件
 ### Step 4: 向用户汇报（必需）
 - [ ] 列出创建的 devflow 档案文件路径（验证文件实际存在于磁盘）
 - [ ] 汇报验证情况（按静态验证、脚本验证、浏览器/人工验证、未验证分类）
 - [ ] 列出剩余风险或后续事项
 - [ ] 询问：**是否现在归档 OpenSpec？**
 ### Step 5: 用户确认后执行 OpenSpec Archive（可选）
 - [ ] 调用 `openspec-archive-change`
 - [ ] 记录 archive 结果
 **自检**：在执行 Step 4 前，检查 Step 1-3 是否都完成。

 ## 目录规则
 项目档案路径：
 ```text
 devflow/projects/YYYY-MM-DD-{slug}/
 ```
 archive 阶段按 `references/scales.md` 的当前分档创建以下文件：
 - `brief.md`：从 proposal.md 提取背景、目标、范围、非目标。
 - `evidence.md`：从 decisions.md 中的 evidence-driven 记录提取；是否独立创建按 `references/scales.md` 执行。
 - `decisions.md`：保持为最终版，整理格式。
 - `acceptance.md`：从实现结果和验证结果提取。
 同时维护仓库级索引：
 - `devflow/index.md`
 按需创建以下扩展文件：
 - `prd.md`
 - `research.md`
 - `design.md`
 - `tasks.md`
 - `alignment.md`
 - `adr/*.md`
 不要逐字复制完整 OpenSpec 文件，也不要重复 OpenSpec 的 proposal/design/tasks。应提炼 OpenSpec 如何指导执行：背景、证据、用户决策、任务状态、假设、验证结果、风险，以及执行中对 OpenSpec 的修正。
 ## 产物分档
 分档的适用场景和必须文件见 `references/scales.md`。本文件只定义 archive 阶段的创建顺序、提取映射和索引规则。
 ## 提取映射
 | 来源 | 提取内容 | 写入位置 |
 | --- | --- | --- |
 | `decisions.md`（过程日志） | question pool、evidence-driven 汇报状态、user-interview 确认状态、关键取舍 | `decisions.md`（整理格式为最终版） |
 | `decisions.md`（过程日志） | evidence-driven 结论、代码/文档证据 | `evidence.md` |
 | `proposal.md` | 为什么做、做什么、范围、非目标 | `brief.md` |
 | `design.md` | 技术方案、关键决策、风险；只提炼长期有用内容 | `evidence.md` / 按需 `design.md` |
 | `specs/**/*.md` | requirement 标题和 scenario 意图 | `brief.md` 或 `acceptance.md` 的验收追踪 |
 | `tasks.md` | checkbox 状态、剩余工作、执行切片 | `acceptance.md`；复杂项目可拆 `tasks.md` |
 | 测试/构建输出 | 验证命令、结果、验证类型 | `acceptance.md` |
 | diagnose 记录 | 根因、修复、回归验证 | `acceptance.md` |
 | 词汇表更新 | 术语和业务规则 | `devflow/glossary/CONTEXT.md` |
 | 可复用经验 | 持久工程知识 | `devflow/compound/YYYY-MM-DD-{type}-{slug}.md` |
 | 项目索引 | 日期、slug、领域、关键词、关联 OpenSpec、状态 | `devflow/index.md` |
 ## 索引维护规则
 `devflow/index.md` 是 context 阶段的默认入口，archive 阶段回填时必须维护。
 最小字段：
 | 日期 | slug | 领域 | 关键词 | 关联 OpenSpec | 状态 |
 | --- | --- | --- | --- | --- | --- |
 规则：
 - 每个 `devflow/projects/YYYY-MM-DD-{slug}/` 默认对应一行索引。
 - archive 阶段新建或更新项目档案时，必须新增或更新对应行。
 - 如果项目仍在进行，状态写 `active`；已验收但未 archive 写 `accepted-unarchived`；已 archive 写 `archived`；暂停写 `paused`。
 - 关键词只放能帮助 context 阶段定位的术语，不复制 brief 内容。
 - 如果无法准确判断领域或状态，写 `unknown`，并在 `acceptance.md` 记录待补。
 ## 验收记录规则
 必须真实记录验证情况，并按类型分类：
 - **静态验证**：语法检查、grep/rg 检查、结构检查、类型检查等不运行完整功能的验证。
 - **脚本验证**：生成脚本、测试命令、构建命令、自动化检查等可重复命令。
 - **浏览器/人工验证**：需要用户或代理在界面中点击、观察、确认的行为验证。
 - **未验证**：未运行的验证必须记录原因、风险和建议补验步骤。
 记录要求：
 - 如果验证通过，记录命令/步骤和覆盖范围。
 - 如果验证失败，记录失败摘要和是否阻塞验收。
 - 如果需要人工验证，列出明确步骤，不要用"手动测试一下"这种模糊描述。
 ## ADR 规则
 同时满足以下条件时创建 ADR：
 1. 决策难以逆转。
 2. 缺少上下文会让未来维护者困惑。
 3. 决策来自真实权衡，而不是简单偏好。
 项目内 ADR 存放于：
 ```text
 devflow/projects/YYYY-MM-DD-{slug}/adr/
 ```
 跨项目可复用决策或经验存放于：
 ```text
 devflow/compound/YYYY-MM-DD-decision-{slug}.md
 ```
 ## 归档确认
 OpenSpec archive 是显式 human-in-the-loop 动作。archive 前必须确认 devflow 已经回填 OpenSpec 的关键执行信息：
 - archive 阶段可以建议 archive，但必须先询问用户。
 - 在用户确认前，不要执行 archive。
 - 如果用户暂不归档，在 acceptance 中记录原因或状态。
 - 如果用户确认归档，执行后记录 archive 结果和剩余档案位置。
 ## 归档交接
 archive 阶段结束时告诉用户：
 - 创建或更新了哪些档案文件。
 - `devflow/index.md` 是否已更新。
 - 运行了哪些验证，并按静态验证、脚本验证、浏览器/人工验证、未验证分类。
 - 还剩哪些风险或后续事项。
 - 明确询问：是否现在 archive OpenSpec change？

 # 内置执行协议
 本文件只在外部 OpenSpec CLI 或子 skill 不可用时使用。fallback 不是跳过阶段，而是由 sm-flow 用文件方式完成同等最小产物。每次使用 fallback 都必须写入 `decisions.md` 或 `acceptance.md`，说明能力来源、缺失能力、影响和剩余风险。
 ## 通用规则
 - 优先使用外部能力；只有不可用、不可发现或无法在当前环境调用时才使用内置协议。
 - 不得因为使用 fallback 跳过 context、grill、commit、apply 授权或 archive 确认。
 - fallback 产物仍写入 `openspec/changes/{slug}/` 和 `devflow/projects/YYYY-MM-DD-{slug}/`。
 - 如果内置协议也无法满足阶段退出条件，暂停并向用户说明阻塞项。
 ## grill 内置协议
 - 建立 question pool，至少覆盖术语、边界、验收；涉及参考实现或项目基础设施时加入技术实现问题。
 - 将问题标记为 `evidence-driven` 或 `user-interview`。
 - 先查证 evidence-driven 问题并汇报结论，再逐个询问 user-interview 问题。
 - 按 `references/scales.md` 的当前分档满足 grill 要求。
 - 将 question pool、证据结论、用户原话和确认状态写入 `decisions.md`；影响实现的结论回写 `proposal.md`。
 ## openspec 提案内置协议
 - 在 `openspec/changes/{slug}/` 创建或更新：
  - `proposal.md`：问题、方案、范围、非目标、上下文约束、风险。
  - 设计产物：实现设计、接口影响、关键决策、架构风险；形式按 `references/scales.md` 的当前分档要求执行。
  - `specs/*/spec.md` 或等价 functional spec：描述用户可观察行为和验收场景。
  - `tasks.md`：按可执行切片拆分任务，并给每项写可验证验收标准。
 - 运行 cross-artifact 对齐检查：proposal → 设计产物 → specs → tasks。
 - 如果发现 gap，先修正 OpenSpec，再进入 commit。
 ## audit 内置协议
 - 用 5 句话以内说明模块链路、数据所有权、跨模块依赖、架构风险和是否需要回写 OpenSpec。
 - 如果风险影响实现，修正设计产物或 `tasks.md`。
 - 将结论写入 `decisions.md`。
 ## openspec apply 内置协议
 - 只依据 Committed OpenSpec 的 specs/tasks 实现；devflow 只作上下文参考。
 - 开始前检查 `.committed` 文件；缺失则返回 commit。
 - 如触发 pre-apply checkpoint，先阅读参考实现、grep 项目基础设施模式，并把技术栈清单写入 `decisions.md`。
 - 按 tasks 的纵向切片实现、验证并更新任务状态。
 - 发现冲突时按三类处理：OpenSpec 不准则修 OpenSpec，代码偏离则修代码，不确定则暂停等用户确认。
 ## openspec archive 内置协议
 - 不删除或移动 OpenSpec change；只标记归档准备状态。
 - 完成 devflow 回填、更新 `devflow/index.md`、创建 `.archive-ready`。
 - 向用户汇报已创建文件、验证分类、剩余风险，并询问是否需要真实 OpenSpec archive。
 - 如果外部 archive 能力仍不可用，在 `acceptance.md` 标记 `accepted-unarchived`。

 # 运行规则
 本文件承载稳定但不必放在顶层 `SKILL.md` 的运行规则。
 ## 接口影响分级
 接口影响分级判断的是"记录在哪里、是否需要独立文档"，不是判断"是否需要关注"。凡涉及字段、DTO、service 方法、API、事件、回调、数据库契约、命令契约、跨模块调用语义或内部决策逻辑变化，都必须先做分级。
 | 级别 | 判断条件 | 产物要求 |
 | --- | --- | --- |
 | L1 内部实现 | 不改变任何调用方可观察的接口、字段、状态、错误码、数据范围、排序、过滤、权限结果、状态流转、副作用或文档承诺 | 不需要接口影响文档，只在 OpenSpec tasks 或 acceptance 记录验证 |
 | L2 内部接口 | 改 DTO、service 方法、内部事件、内部 RPC 或内部判断逻辑，且所有消费者都在同一实现范围内 | 必须记录接口影响范围，可内联到 OpenSpec design/specs/tasks 或 devflow evidence/decisions |
 | L3 协作接口 | 影响其他模块、其他服务、前端、外部系统、跨团队消费者、数据库契约、消息事件、回调或 SDK | 必须产出独立接口文档或等价独立章节 |
 | L4 破坏性接口 | 删除字段、改字段语义、改状态机、改错误码、破坏兼容、旧调用方可能失败，或需要迁移、灰度、回滚 | 独立接口文档 + 迁移/回滚说明；必要时创建 ADR |
 判断策略：
 - 如果只是修复 bug，让接口回到原 OpenSpec 或原文档承诺，通常是 L1/L2。
 - 如果判断逻辑改变了返回数据、错误码、状态、权限结果、排序/过滤、幂等性、时序或副作用，至少按 L3 检查。
 - 如果旧调用方不改代码会失败、少数据、多数据、状态不同或错误码不同，按 L4 处理。
 - 如果无法确定调用方边界或兼容性，默认提高一级并作为 `user-interview` 问题等待确认。
 ## 启动检查
 1. 识别用户命令意图：
   - `/sm-flow`（无参数）：完整流程，从 clarify 开始。
   - `/sm-flow apply [change]`：只执行，检查 commit gate → apply。
   - `/sm-flow explore`：带上下文的探索模式，不走标准阶段链。
   - `/sm-flow archive [change]`：收尾，回填 devflow + 归档确认。
   - 明确要求"使用 sm-flow"或"走 sm-flow 流程"：按显式调用处理。
   - 自然语言指定阶段继续：识别意图后，自动补做最小前置检查，然后从指定阶段继续。
 2. 判断启动模式：
   - 完整模式：用户提供粗略想法或初始 PRD。
   - Research 模式：用户已有 research，需要转成或修正 OpenSpec。
   - PRD 文件模式：用户提供已有 PRD 路径。
   - 恢复模式：用户希望从某个阶段继续（补做最小前置检查）。
   - 快速模式：小改动，合并 gate；具体分档规则见 `references/scales.md`。
 3. 如果缺少 `devflow/`，初始化：
   - `devflow/projects/`
   - `devflow/glossary/CONTEXT.md`
   - `devflow/compound/`
 4. 如果根目录存在旧 `CONTEXT.md`，且 `devflow/glossary/CONTEXT.md` 不存在或为空，询问用户是迁移还是合并。
 5. 检查 OpenSpec 和子 skill 是否可用：
   - OpenSpec 能力：`openspec-propose`、`openspec-apply-change`、`openspec-archive-change`。
   - 辅助能力：`to-prd`、`grill-with-docs`、`diagnose`、`tdd`、`zoom-out`。
 6. 如果 OpenSpec 或子 skill 不可用，不要静默跳过；使用内置执行协议（见 `references/fallbacks.md`），并在当前 checkpoint 说明 fallback 来源、影响和剩余风险。
 ## 进度汇报
 用户可见进度默认折叠为 4 个 checkpoint：
 | Checkpoint | 内部阶段 |
 | --- | --- |
 | Discover | clarify + context + propose + grill |
 | Commit | specify + audit + commit |
 | Apply | apply |
 | Archive | archive |
 汇报规则：
 - 面向用户时优先使用 checkpoint 名称，不逐个汇报 9 个内部阶段。
 - 内部阶段只在 checkpoint 摘要中作为证据列出，例如"Discover 已完成：读取了 devflow、生成 proposal、解决 2 个问题"。
 - 只有发生阻塞、冲突、fallback、用户要求继续某个内部阶段，或需要解释恢复位置时，才暴露内部阶段名。
 - 当前分档的汇报压缩规则见 `references/scales.md`；无论分档如何，都不要把内部阶段名当作用户操作入口。
 ## 项目标识规则
 - 整个流程使用同一个 slug。
 - 优先使用 OpenSpec change name。
 - 如果还没有，则从功能标题生成 kebab-case slug。
 - 项目档案目录格式：`devflow/projects/YYYY-MM-DD-{slug}/`。
 - 如果目录已存在，默认恢复该项目；除非用户明确要求新开一轮。
 ## Devflow 产物分层
 Devflow 是 sm-flow 自动维护的项目长期记忆层，不复制 OpenSpec 的执行产物。
 **过程日志**（clarify → apply 期间维护）：
 - `decisions.md`：question pool、evidence-driven 汇报状态、user-interview 确认状态、关键取舍、风险接受、OpenSpec 回写记录、冲突分类记录。
 **最终档案**（archive 阶段从 decisions.md + OpenSpec 产物提取）：
 - `brief.md`：背景、目标、范围、非目标、分档、关联 OpenSpec change。
 - `evidence.md`：代码/文档证据、历史决策、evidence-driven 结论和汇报状态；分档要求见 `references/scales.md` 和 `references/archive-rules.md`。
 - `acceptance.md`：实现结果、验证命令、未验证项、归档状态、后续事项。
 **按需产物**（archive 阶段按需创建）：
 - `prd.md`：需求复杂、用户明确要求、或需要对外协作。
 - `research.md`：存在真实调研、代码考古、竞品/API 对比或复杂方案比较。
 - `design.md`：不适合放进 OpenSpec design 的长期背景或架构审计摘要。
 - `tasks.md`：跨会话的人类追踪；执行任务仍属于 OpenSpec。
 - `alignment.md` / `clarifications.md`：仅在 gap 或澄清很多时使用。
 - `adr/*.md` 和 `compound/*.md`：仅在满足 ADR / compound knowledge 规则时使用。
 **规模分档**：`micro / standard / complex` 的唯一规则源是 `references/scales.md`。
 ## 快速模式
 快速模式适用于 `references/scales.md` 定义的 micro 变更。它合并 gate 而不仅仅是压缩产物；具体覆盖规则见 `references/scales.md`。
 无论什么模式，以下内容必须保留：
 - context 最小上下文收集：至少检查 glossary 和相关 ADR。
 - grill 最小澄清：按 `references/scales.md` 当前分档要求执行；evidence-driven 结论仍需汇报。
 - commit gate：确认没有未解决用户问题、接口影响已记录、OpenSpec tasks/specs 可执行；完整性检查按 `references/scales.md` 当前分档要求执行。
 - apply 仍由 OpenSpec tasks/specs 驱动执行。
 - archive 轻量回填：记录验收结果、OpenSpec 链接和归档状态。
 ## 完成标准
 只有同时满足以下条件，流程才算完成：
 - 用户可见的 Discover、Commit、Apply、Archive checkpoint 已完成，或未完成项已明确标记为暂停/不适用。
 - OpenSpec proposal、设计产物、specs、tasks 已按当前分档生成或更新到可执行状态。
 - 实现或规划工作已完成，且执行依据来自 OpenSpec。
 - 已运行验证，或已记录未运行验证的原因。
 - `devflow/projects/YYYY-MM-DD-{slug}/` 包含 `references/scales.md` 和 `references/archive-rules.md` 要求的当前分档档案。
 - 用户知道剩余风险与下一步，并已被询问是否归档 OpenSpec change。

 # 阶段契约
 本文件是 SM Flow 的逐阶段执行准则。核心原则：**sm-flow 编排 OpenSpec，OpenSpec 指挥执行，执行结果回填 devflow**。
 执行顺序：clarify → context → propose → grill → specify → audit → commit → apply → archive。
 ## 目录
 - clarify — 入口澄清
 - context — 上下文收集
 - propose — 轻量 propose
 - grill — 人类对齐澄清
 - specify — 细化 + 对齐
 - audit — 架构审计
 - commit — Commit OpenSpec
 - apply — OpenSpec 执行
 - archive — 回填 + 归档
 ## clarify — 入口澄清
 **进入条件**：用户提供粗略想法、初始 PRD、已有 research、issue，或要求启动 SM Flow。
 **动作**：
 - 收集问题、期望结果、目标用户、涉及代码区域、约束条件和可能的非目标。
 - 如果用户已有 research，先识别它是否已经包含用户价值、技术方案、验收标准和任务拆分。
 - 如果输入过于模糊，最多追加三轮聚焦问题。
 - 当答案会改变 OpenSpec proposal/specs/tasks 时，优先一次只问一个问题。
 - 如果需要判断 `micro / standard / complex` 分档，补读 `references/scales.md`。
 **退出条件**：
 - 问题可以用 1-2 句话说清楚。
 - 期望结果可以用 1-2 句话说清楚。
 - 已列出已知影响代码或模块；如果未知，也明确标记。
 - 可以生成 OpenSpec change slug。
 **输出**：
 - 入口摘要。
 - 初步 slug。
 - devflow 规模分档：`micro` / `standard` / `complex`。
 ## context — 上下文收集
 **进入条件**：clarify 已经有足够信息定位领域、项目或变更方向。
 **动作**：
 - 优先读取 `devflow/index.md`，按日期、slug、领域、关键词和关联 OpenSpec 定位候选项目。
 - 如果 `devflow/index.md` 不存在，先从 `devflow/projects/` 现有目录初始化轻量索引，再继续本次上下文收集。
 - 读取 `devflow/glossary/CONTEXT.md`，提取相关术语和业务规则。
 - 搜索 `devflow/projects/` 中相关 PRD、design、tasks、acceptance 和 ADR。
 - 搜索 `devflow/compound/` 中可复用 learning、trick、decision、explore。
 - 记录哪些上下文会影响 OpenSpec proposal、设计产物、specs 或 tasks。
 - 如果发现旧根目录 `CONTEXT.md` 与 `devflow/glossary/CONTEXT.md` 冲突，暂停并向用户汇报。
 **退出条件**：
 - 已形成"OpenSpec 输入上下文摘要"。
 - 已记录 `devflow/index.md` 的使用状态：已命中 / 已初始化 / 无相关条目。
 - 已列出相关 ADR 和不能违反的历史决策。
 - 已列出需要写入或修正 OpenSpec 的上下文点。
 **输出**：
 - 上下文摘要，写入 `decisions.md`（过程日志）。会影响实现的上下文必须标记为"需进入 OpenSpec"。
 ## propose — 轻量 propose
 **进入条件**：clarify + context 已经足够生成轻量 proposal。
 **执行者**：sm-flow 内置协议。**不调用 openspec-propose**（完整 OpenSpec 产物留待 specify 阶段生成）。
 **动作**：
 - 创建或识别 `openspec/changes/{slug}/`。
 - 写入 `proposal.md`，包含：问题、建议方案、范围、非目标、来自 devflow 的上下文约束、风险。
 - **不生成 design.md、specs/、tasks.md**——这些留待 grill 澄清需求后在 specify 阶段补全。
 - 用 context 阶段的 devflow 上下文增强 proposal。
 - 在承诺方案方向前，先检查相关仓库代码。
 **退出条件**：
 - `openspec/changes/{slug}/proposal.md` 存在。
 - 关键假设已显式记录。
 **输出**：
 - Draft OpenSpec proposal.md（轻量版）。
 **Human checkpoint**：
 - 向用户简要说明 proposal 范围、关键假设、主要风险、devflow 上下文如何影响方案。
 - 作为 Discover checkpoint 的中间状态汇报；询问是否继续完成 Discover 的人类澄清部分。用户明确要求"全自动执行"时可跳过等待。
 ## grill — 人类对齐澄清
 **进入条件**：propose 已有轻量 proposal.md。
 **能力来源**：优先使用 `grill-with-docs`；不可用时使用 `references/fallbacks.md#grill-内置协议`，并在 `decisions.md` 标注 fallback。
 **动作**：
 - 优先使用 `grill-with-docs`。
 - 进入 grill 时先建立一个 question pool，并记录到 `decisions.md`：
  - 默认至少覆盖术语、边界、验收三个维度。
  - **技术实现维度**（新增）：当 proposal 提到参考实现、或涉及项目现有基础设施时，增加技术澄清问题：
    - 参考实现的具体文件路径是什么？
    - 项目现有的 [请求结构/MQ/缓存/加密/工具类] 标准是什么？
    - 有哪些技术点需要先调研或新建？
  - 如果变更涉及多模块、接口、权限、下游消费者、响应结构或生命周期规则，先把这些维度补进问题池。
 - 逐项标记每个问题的模式：
  - `evidence-driven`：问题能通过代码、文档、测试、OpenSpec 或既有 ADR 证明；代理先查证，再向用户汇报证据、结论和是否需要确认。
  - `user-interview`：问题涉及产品偏好、范围边界、验收口径、风险接受度或价值取舍；必须问用户并等待确认。
 - evidence-driven 和 user-interview 的推进节奏：先批量查证 evidence-driven 并一次性汇报结论，再逐个处理 user-interview 问题。不要把所有问题攒到最后一起问。
 - 一次只问一个 `user-interview` 问题。
 - 每个 `user-interview` 问题必须等待用户显式回答，并在 decisions.md 中记录：问题原文、用户原话、确认状态（已确认/未确认）。未确认的问题不能从 question pool 移除。
 - 单个 `user-interview` 的确认只能解除该问题本身的阻塞，不能被解释为进入 apply 或修改执行目标文件的授权。
 - 对接口影响等级、消费者边界或兼容性存在不确定时，必须作为 `user-interview` 问题等待用户确认。
 - 如果澄清结果影响实现，必须回写 proposal.md。
 - 术语一旦确认，更新 `devflow/glossary/CONTEXT.md`。
 - 对难以逆转、依赖上下文、源自真实权衡的决策创建 ADR。
 **退出条件**：
 - question pool 已建立并覆盖当前 change 所需维度。
 - 已满足 `references/scales.md` 中当前分档的 grill 要求。每个问题都必须记录属于 `evidence-driven` 还是 `user-interview`。
 - 所有 evidence-driven 结论已向用户汇报。
 - 所有 user-interview 决策已获得用户确认。
 - 没有未解决或代理代确认的 user-interview 问题。
 - 没有未判级或未确认的接口影响问题。
 - 影响实现的结论已回写 proposal.md。
 - 单个 grill 决策确认不等于 apply 授权；grill 完成后必须停在 commit，等待用户明确要求进入 apply。
 - question pool、evidence-driven 结论、user-interview 确认必须写入 `decisions.md` 文件，不能只记录在对话中。
 **输出**：
 - 更新后的 proposal.md。
 - 澄清记录：写入 `decisions.md`。包含 question pool、evidence-driven 汇报状态、user-interview 确认状态。
 - 更新后的词汇表和 ADR。
 **Human checkpoint**：
 - 汇报已解决和未解决的问题、proposal 变更、术语和 ADR 更新。
 - 汇报 Discover checkpoint 完成情况，并询问是否继续进入 Commit checkpoint。
 ## specify — 细化 + 对齐
 **进入条件**：grill 已退出，需求已通过澄清稳定下来。
 **能力来源**：优先使用 `openspec-propose`（基于已稳定的 proposal 补全完整 OpenSpec）；按需使用 `to-prd`。进入本阶段必须先声明调用方式；外部能力不可用时使用 `references/fallbacks.md#openspec-提案-内置协议`，并在 `decisions.md` 标注 fallback。
 **动作**：
 - 基于已稳定的 proposal.md 补全设计产物、specs/、tasks.md：
  - 优先调用 `openspec-propose`，输入中明确说明"proposal.md 已存在，本次只需按当前分档补全设计产物/specs/tasks"。
  - 如果不可用，执行 `references/fallbacks.md#openspec-提案-内置协议`。
 - 如果没有结构化 PRD，按需按 `to-prd` 协议生成 `brief.md`；复杂需求、对外协作或用户明确要求时再生成 `prd.md`。
 - 独立 PRD 是否需要按 `references/scales.md` 的当前分档和用户要求判断。
 - 用 grill 阶段的 decisions.md 记录增强 OpenSpec 产物：确保 design/specs/tasks 反映所有已确认的决策。
 - **显式 cross-artifact 对齐检查**——在 checkpoint 中输出对齐检查表：
  - `brief/prd` 中的目标、范围、非目标和验收预期 → `proposal` 是否覆盖。
  - `proposal` 中的范围、约束和关键承诺 → `design` 是否覆盖。
  - `design` 中影响实现的约束、接口影响和架构结论 → `specs` 或 `tasks` 是否覆盖。
  - `specs` 中的可观察行为 → `tasks` 是否覆盖为可执行切片。
  - 每项标记：已对齐 / 存在 gap。
 - 检查是否涉及接口影响：
  - 接口影响分级定义见 `references/operating-rules.md#接口影响分级`。
  - 是否改变字段、DTO、service 方法、API、事件、回调、数据库契约、命令契约或跨模块调用语义。
  - 接口内部判断逻辑是否改变调用方可观察行为。
  - 按 L1/L2/L3/L4 记录接口影响等级；不确定时标记为 `user-interview` 问题。
 - 如果存在 gap，在进入下一阶段前修复 OpenSpec。
 - 如果发现不一致，优先修正 OpenSpec，而不是只修改 devflow 文档。
 **退出条件**：
 - OpenSpec 细化产物存在且与 proposal 对齐；产物形态按 `references/scales.md` 的当前分档要求执行。
 - `brief.md` 已覆盖背景、目标、范围和非目标；复杂需求存在独立 `prd.md` 或用户明确不需要 PRD。
 - cross-artifact 对齐检查表已生成（4 行，每行标记已对齐/存在 gap），没有未处理 gap。
 - 涉及接口变更时，已记录接口影响等级和产物要求；不确定项已标记。
 - 所有已知冲突已修正或等待用户决策。
 **输出**：
 - Draft OpenSpec：按 `references/scales.md` 的当前分档要求生成 proposal、设计、specs 和 tasks。
 - `brief.md`，以及按需创建的 `prd.md`。
 - cross-artifact 对齐检查表（写入 checkpoint 或 decisions.md）。
 - 必要的 OpenSpec 修正。
 ## audit — 架构审计
 **进入条件**：specify 已退出，完整 OpenSpec 产物已存在。
 **能力来源**：优先使用 `zoom-out`；不可用时使用 `references/fallbacks.md#audit-内置协议`，并在 `decisions.md` 标注 fallback。
 **动作**：
 - 画出输入 → 处理 → 输出的模块链路。
 - 识别跨模块依赖、数据所有权、生命周期和耦合风险。
 - 检查是否与既有架构、ADR、OpenSpec design 冲突。
 - 用不超过五句话写出架构风险评估。
 - 如果审计结果影响实现，必须回写 OpenSpec design/tasks；只写入 devflow design 不够。
 - 审计结论写入 `decisions.md`。
 **退出条件**：
 - 架构风险已被接受，或流程返回 grill/specify 修正 OpenSpec。
 - OpenSpec 设计产物/tasks 已反映会影响实现的架构审计结论。
 **输出**：
 - 架构审计记录，写入 `decisions.md`；复杂架构审计可拆出 `design.md`。
 - 必要的 OpenSpec 设计产物/tasks 修正。
 **Human checkpoint**：
 - 用不超过五句话向用户说明架构风险、OpenSpec 修正点和实现计划。
 - 作为 Commit checkpoint 的中间状态汇报；询问是否继续完成 commit gate。
 ## commit — Commit OpenSpec
 **进入条件**：
 - grill 已满足 `references/scales.md` 中当前分档要求。
 - 所有 `user-interview` 问题都已获得用户显式确认。
 - audit 已经完成，或快速模式下已记录跳过原因；快速模式定义见 `references/operating-rules.md#快速模式`。
 - Draft OpenSpec 已回写所有会影响实现的澄清、接口影响和架构审计结论。
 **动作**：
 - 检查 proposal 是否说明为什么做、做什么、范围和非目标。
 - 检查 design 是否记录上下文约束、关键技术决策、架构风险和接口影响。
 - 检查 specs 是否表达外部可观察行为，并覆盖验收口径。
 - 检查 tasks 是否是可执行的纵向切片，而不是泛泛描述。
 - 复核 cross-artifact 对齐：`brief/prd → proposal → 设计产物 → specs → tasks` 是否闭环，没有把字段、范围项、验收行为或实现切片丢在上游产物里。
 - 检查 `decisions.md` 中所有影响实现的发现，是否已回写到 proposal、design、specs 或 tasks。
 - 接口影响分级定义见 `references/operating-rules.md#接口影响分级`。
 - 检查接口影响是否已按 L1/L4 判级；L3/L4 是否有独立接口文档或等价独立章节。
 - 检查没有未汇报的 evidence-driven 结论，没有未确认的 user-interview 问题，没有 devflow/OpenSpec 冲突。
 - 如果检查失败，返回 propose、grill、specify 或 audit 修正 Draft OpenSpec。
 **退出条件**：
 - Draft OpenSpec 已达到可执行状态，并记录为 Committed OpenSpec。
 - **文件完整性检查**（按 `references/scales.md` 的当前分档要求执行）：
  - [ ] proposal 存在，且足以说明问题、建议方案、范围和非目标。
  - [ ] 设计产物存在，形式符合当前分档要求。
  - [ ] specs 存在，且表达用户可观察行为。
  - [ ] tasks 存在，且任务可执行、验收标准可验证。
 - **一致性检查**（必须通过）：
  - [ ] proposal 中的核心概念在设计产物中有对应设计
  - [ ] 设计产物中的关键决策在 tasks 中有对应实现任务
  - [ ] tasks 的验收标准可验证（不是"正确实现""完成功能"这类模糊描述）
 - **标记文件**：检查通过后，创建 `openspec/changes/{slug}/.committed` 文件标记为 Committed OpenSpec
 - 所有 preflight 风险已消除或明确记录为已接受。
 **输出**：
 - Committed OpenSpec 状态说明。
 - preflight 检查结果，写入 `decisions.md` 或 `acceptance.md`。
 **Human checkpoint**：
 - 用不超过五句话说明 Committed OpenSpec 的范围、接口影响、剩余风险和执行计划。
 - 汇报 Commit checkpoint 完成情况，并询问是否进入 Apply checkpoint；除非用户在启动时明确要求"全自动执行"，必须等待用户明确说出进入 apply、开始实现、执行修改或等价授权。
 - 不得把 grill 的单个决策确认当作本 checkpoint 的授权。
 ## apply — OpenSpec 执行
 **进入条件**：
 - `openspec/changes/{slug}/` 中 proposal、设计产物、specs、tasks 已通过 commit，成为 Committed OpenSpec。
 - **前置门控检查**（硬约束）：
  - 检查 `openspec/changes/{slug}/.committed` 文件是否存在
  - 如不存在，执行以下流程：
    1. 汇报：Draft OpenSpec 未通过 commit 检查
    2. 列出缺失的 checkpoint 项（文件完整性、一致性检查）
    3. 询问用户：是否补做 commit 检查；如用户要求不补做，则中止 apply 或标记为 `emergency-bypass`，且本次流程不得视为合规 sm-flow apply
 - commit 后已获得用户明确的 apply 授权，除非用户在启动时要求"全自动执行"。
 - devflow 与 OpenSpec 没有未解决冲突。
 - 没有未解决的 user-interview 问题、未判级接口影响、未汇报 evidence-driven 结论或未接受架构风险。
 **能力来源**：优先使用 `openspec-apply-change`；不可用时使用 `references/fallbacks.md#openspec-apply-内置协议`，并在 `decisions.md` 标注 fallback。遇到 bug/不确定行为时优先使用 `diagnose`；需要测试驱动时优先使用 `tdd`。不可用时执行对应最小协议并记录原因，不得静默跳过。
 **动作**：
 ### Pre-apply Checkpoint
 **触发条件**：当 OpenSpec 涉及以下任一情况时必须执行
 - design 或 tasks 中提到"参考 XXX 实现"
 - 需要调用项目现有基础设施（MQ/统一请求结构/工具类等）
 - 技术栈不熟悉或第一次在该项目实现类似功能
 **执行步骤**：
 1. **阅读所有参考实现**
   - 从 OpenSpec design 或 tasks 中定位参考实现文件
   - 如果路径不明确，通过 Grep 搜索关键类名或模式
   - 理解关键逻辑，提取可复用代码片段和模式
 2. **Grep 关键技术栈**
   - 请求/响应结构模式（如 `RequestMsg`、`ResponseMsg`、DTO 规范）
   - 消息队列模式（如 `@KafkaListener`、`@YkMsg`、发送模板）
   - 统一工具类（如 `XxxUtil`、`XxxHelper`、加密/验签工具）
   - 异常处理和日志记录标准
 3. **形成技术栈清单并写入 decisions.md**
   - 项目使用的请求/响应结构标准
   - MQ 消息定义和发送标准
   - Consumer 标准位置和写法
   - 加密/验签/工具类的标准用法
   - 识别需要新建的工具类或基础设施
 **输出要求**：
 - 技术栈清单已写入 `decisions.md` 的 "Pre-apply Research" 章节。
 - 已列出所有参考实现的文件路径。
 - 已识别需要新建的工具类/基础设施。
 **按风险执行**：执行深度按 `references/scales.md` 的当前分档和实现风险决定；退出判断以清单是否足以指导实现为准。
 ### 实现过程
 - 优先调用 `openspec-apply-change`。
 - 执行依据是 OpenSpec specs/tasks；devflow 只能作为上下文参考。
 - 按 OpenSpec tasks 的纵向切片实现。
 - **分步实现**：建议按 Controller → Service → MQ/异步组件 → Consumer/下游 顺序，每完成一层验证后再继续。
 - 进入实现前先汇报本阶段的 capability 来源、当前 task 进度和本轮要推进的切片；否则 apply 不算真正开始。
 - **首模块完成后对齐检查**：完成第一个接口/模块后，对比 OpenSpec design/tasks，标记"已完成/TODO"；核心功能（加密/验签/核心业务逻辑）不允许空实现或纯 TODO 注释。
 - 当用户质疑、用户要求修改、代码检查、测试失败或运行行为与 OpenSpec 冲突时，做三类判断：
  - OpenSpec 不准（规格遗漏、边界未覆盖、验收口径缺失）→ 暂停 apply，修正 OpenSpec 后重新提交。
  - 代码偏离（实现没按 OpenSpec 做）→ 修正代码，不改 OpenSpec。
  - 不确定根因、涉及设计方向、用户改变目标或范围 → 暂停并等待用户确认。
 - 判断结果、证据、用户确认和 OpenSpec 回写状态必须记录到 `decisions.md`。
 - **快速失败**：连续返工 ≥ 2 次时，暂停并重新执行 pre-apply checkpoint 或向用户汇报。
 - 当用户要求、行为复杂或回归风险高时使用 TDD。
 - 当测试失败、行为意外或原因不确定时使用 diagnose。
 - 如果 diagnose 发现根因是 OpenSpec 不准确，先修正 OpenSpec，再继续 apply。
 - 修改文件前遵守仓库指令，例如 `AGENTS.md`。
 **退出条件**：
 - 已完成 pre-apply checkpoint（如触发条件满足），技术栈清单已写入 `decisions.md`。
 - OpenSpec tasks 已完成，或剩余 tasks 已明确记录。
 - 核心功能已实现或明确标注"待联调"，无纯 TODO 占位。
 - 所有实现期冲突已分类并处理；没有未确认的规格遗漏、设计冲突或用户变更。
 - 已运行验证，或记录了未验证原因。
 - 已列出已知限制。
 **输出**：
 - 代码变更、必要测试和实现说明。
 - 更新后的 OpenSpec task 状态。
 - 冲突记录写入 `decisions.md`。
 ## archive — 回填 + 归档
 **进入条件**：实现或规划工作已经达到可交接状态。
 **能力来源**：`openspec-archive-change` 在用户确认 archive 后优先调用；不可用时使用 `references/fallbacks.md#openspec-archive-内置协议`，并在 `acceptance.md` 标注 fallback。archive 回填由 `sm-flow` 执行。
 **动作**：
 - 遵循 `references/archive-rules.md`。
 - 从 `decisions.md`（过程日志）+ OpenSpec 产物提炼完整 devflow 档案：
  - `brief.md`：从 proposal.md 提取背景、目标、范围、非目标。
  - `evidence.md`：按 `references/scales.md` 和 `references/archive-rules.md` 的当前分档要求处理。
  - `decisions.md`：保持为最终版，整理格式。
  - `acceptance.md`：从实现结果和验证结果提取。
 - 只在复杂场景按需拆出 PRD/research/design/tasks/alignment。
 - 写入或更新验收记录，并区分静态验证、脚本验证、浏览器/人工验证、未验证。
 - 如果本次流程产生可复用经验，写入 compound knowledge。
 - 更新 `devflow/index.md`，记录日期、slug、领域、关键词、关联 OpenSpec 和状态。
 - 询问用户是否要 archive OpenSpec change；不要默认执行归档。
 **退出条件**：
 - `devflow/projects/YYYY-MM-DD-{slug}/` 包含 `references/scales.md` 和 `references/archive-rules.md` 要求的当前分档档案；archive checkpoint 必须列出所有已创建的文件路径，验证文件实际存在于磁盘。
 - `devflow/index.md` 已包含或更新本项目条目。
 - 用户已被询问是否 archive OpenSpec change。
 **输出**：
 - 完整 devflow 档案。
 - 归档交接清单：创建或更新了哪些文件、验证分类、剩余风险、是否 archive。

 # 分档规则
 本文件是 `micro / standard / complex` 的唯一规则源。其它文件只引用本文件，不重复定义分档细节。
 ## standard 基准
 standard 是默认分档，适用于普通功能、明确但有一定实现范围的变更。
 - 用户可见 checkpoint：Discover → Commit → Apply → Archive。
 - OpenSpec 产物：`proposal.md`、独立 `design.md`、`specs/`、`tasks.md`。
 - grill：解决术语、边界、验收三个维度的高价值问题。
 - commit gate：检查 proposal、design、specs、tasks 的完整性和一致性。
 - devflow 档案：`brief.md`、`evidence.md`、`decisions.md`、`acceptance.md`。
 ## micro 覆盖
 micro 适用于小改动、低风险、需求明确的变更。micro 是 standard 的减法，不是跳过流程。
 - checkpoint 可合并：Discover + Commit 可在无阻塞时合并汇报。
 - micro 内部流程压缩为：clarify+context 合并 checkpoint → 轻量 propose → grill → specify+commit 合并 checkpoint。
 - context 保留最小收集：至少检查 glossary 和相关 ADR。
 - grill 保留最小澄清：至少解决一个高价值问题，并记录术语、边界、验收三类是否明确；不明确项必须补问或标记风险。
 - OpenSpec 仍需要 `proposal.md`、`specs/`、`tasks.md`。
 - `design.md` 可不独立创建；允许在 `proposal.md` 或 `tasks.md` 中写等价设计小节。
 - `specs/` 和 `tasks.md` 可轻量，但必须表达可观察行为和可执行任务。
 - commit gate 仍必须通过，并创建 `.committed`。
 - devflow 档案至少包含 `brief.md`、`decisions.md`、`acceptance.md`；证据少时可并入 `brief.md` 或 `decisions.md`。
 - apply 仍只能依据 Committed OpenSpec。
 - archive 仍要轻量回填 devflow，并询问是否归档 OpenSpec。
 micro 不适用于接口影响不清、跨团队消费者、迁移/回滚、复杂状态机、长期架构决策或需求边界不清的变更；遇到这些情况应升级为 standard 或 complex。
 ## complex 增量
 complex 适用于高风险、跨模块、需求不清、多人协作或长期架构影响明显的变更。complex 是 standard 的加法。
 - 需要更完整的 Discover：增加需求澄清、证据查证、范围确认和风险接受。
 - checkpoint 内可补充关键内部阶段结果，但不要把内部阶段名当作用户操作入口。
 - 按需创建 `prd.md`、`research.md`、`alignment.md`、接口文档、ADR 或 compound knowledge。
 - 接口影响、迁移、灰度、回滚、兼容性和消费者边界必须显式记录。
 - audit 需要覆盖模块链路、数据所有权、生命周期、耦合风险和 ADR 冲突。
 - archive 在 standard 档案基础上按需提炼长期 design、research、tasks、ADR 和 compound knowledge。

 # AI Ops Prompt 配置化 & LookupKnowledgeTool 集成
 **日期**: 2026-06-24  
 **类型**: 功能增强 + 架构优化  
 **影响范围**: AI Ops 服务
 ---
 ## 一、变更背景
 ### 1.1 问题
 - **硬编码 Prompt**：Planner、Executor、Supervisor 的系统提示词硬编码在 `AiOpsService.java` 中，难以维护和版本控制
 - **缺少知识库精确检索**：现有 `InternalDocsTools` 只支持 L1 语义检索（200-500ms），对于错误码、配置项等精确关键词查询效率较低
 ### 1.2 解决方案
 1. **Prompt 配置化**：将所有 Agent 的 Prompt 抽取到 `prompts/ai-ops-prompts.yml` 配置文件
 2. **集成 L0+L1 混合检索**：引入 `LookupKnowledgeTool`，支持精确关键词匹配（< 10ms）+ 语义检索补充
 ---
 ## 二、架构变更
 ### 2.1 Prompt 配置化架构
 ```
 AiOpsService
    ↓ 注入
 AiOpsPromptProperties (配置类)
    ↓ @PostConstruct 加载
 ClassPathResource 读取 Markdown 文件
    ↓ 读取
 prompts/
 ├── planner-prompt.md
 ├── executor-prompt.md
 └── supervisor-prompt.md
 ```
 **优点**：
 - 易于维护：Prompt 修改不需要重新编译
 - 格式友好：Markdown 格式支持代码块、表格，无 YAML 转义问题
 - 版本控制：配置文件独立管理
 - 易于扩展：后续可按环境区分（dev/prod）
 ### 2.2 工具层增强
 ```
 原有工具：
 - queryInternalDocs (纯 L1 语义检索，200-500ms)
 新增工具：
 - lookup_knowledge (L0 精确匹配 + L1 补充，< 10ms 高置信度)
 ```
 **使用策略**：
 - 精确关键词（错误码、配置项）→ `lookup_knowledge`，未找到时降级到 `queryInternalDocs`
 - 模糊概念、故障流程 → 直接使用 `queryInternalDocs`
 ---
 ## 三、核心改动
 ### 3.1 新增文件
 #### `AiOpsPromptProperties.java`
 ```java
@Configuration
 public class AiOpsPromptProperties {
    private String planner;
    private String executor;
    private String supervisor;
    @PostConstruct
    public void loadPrompts() {
        planner = loadPromptFromFile("prompts/planner-prompt.md");
        executor = loadPromptFromFile("prompts/executor-prompt.md");
        supervisor = loadPromptFromFile("prompts/supervisor-prompt.md");
    }
    private String loadPromptFromFile(String path) throws IOException {
        ClassPathResource resource = new ClassPathResource(path);
        return new String(resource.getInputStream().readAllBytes(), StandardCharsets.UTF_8);
    }
 }
 ```
 #### `prompts/*.md`
 三个独立的 Markdown 文件，包含 Agent 的完整系统提示词：
 - `planner-prompt.md` - Planner Agent 系统提示词
 - `executor-prompt.md` - Executor Agent 系统提示词（含工具选择指南）
 - `supervisor-prompt.md` - Supervisor Agent 系统提示词
 ### 3.2 修改文件
 #### `AiOpsService.java`
 **注入新组件**：
 ```java
@Autowired
 private LookupKnowledgeTool lookupKnowledgeTool;
@Autowired
 private AiOpsPromptProperties promptProperties;
 ```
 **使用配置化 Prompt**：
 ```java
 // 原来
 .systemPrompt(buildPlannerPrompt())
 // 改为
 .systemPrompt(promptProperties.getPlanner())
 ```
 **添加工具到工具数组**：
 ```java
 return new Object[]{
    dateTimeTools, 
    internalDocsTools, 
    queryMetricsTools, 
    lookupKnowledgeTool  // 新增
 };
 ```
 **删除方法**：
 - `buildPlannerPrompt()`
 - `buildExecutorPrompt()`
 - `buildSupervisorSystemPrompt()`
 ---
 ## 四、Executor Prompt 变更详情
 ### 4.1 新增工具选择指南
 ```yaml
 - 根据查询内容选择合适的工具：
  * 精确关键词（错误码、配置项名称）→ 优先使用 lookup_knowledge，未找到时降级到 queryInternalDocs
  * 模糊概念、故障流程 → 直接使用 queryInternalDocs
  * 告警数据 → queryPrometheusAlerts
  * 日志数据 → queryLogs
 ```
 ### 4.2 降级策略
 关键改进：明确了 `lookup_knowledge` 未找到时的降级策略。
 **流程**：
 ```
 1. Planner: "查询 ERR_TIMEOUT 定义"
 2. Executor: 调用 lookup_knowledge("ERR_TIMEOUT")
 3a. 如果 found=true, confidence=high → 使用 primary.content
 3b. 如果 found=false → 自动降级到 queryInternalDocs("ERR_TIMEOUT 超时错误")
 4. 返回 feedback 给 Planner
 ```
 ---
 ## 五、兼容性说明
 ### 5.1 向后兼容
 ✅ **完全兼容**：
 - 现有工具调用逻辑不变
 - 3-Agent 协同模式不变
 - Planner/Executor/Supervisor 的职责边界不变
 ### 5.2 新增依赖
 - `LookupKnowledgeTool` 依赖 `KnowledgeIndexService` 和 `VectorSearchService`
 - 需要 `knowledge_base/` 目录存在（已在 `application.yml` 中配置）
 ---
 ## 六、验证清单
 ### 6.1 编译验证
 ```bash
 mvn clean compile -DskipTests
 ```
 ✅ **结果**: BUILD SUCCESS
 ### 6.2 运行时验证（待完成）
 - [ ] 启动应用，验证 Prompt 配置加载成功
 - [ ] 触发 AI Ops 流程，验证 `lookup_knowledge` 工具可调用
 - [ ] 测试精确关键词查询（如 "ERR_TIMEOUT"）
 - [ ] 测试降级策略（查询不存在的关键词）
 ---
 ## 七、后续工作
 ### 7.1 知识库内容准备
 当前 `knowledge_base/` 目录需要补充文档：
 - 错误码定义（支付网关、订单系统等）
 - 配置最佳实践（Redis、HikariCP、Flyway 等）
 - 故障排查流程
 **文档格式示例**：
 ```markdown
 ---
 title: 支付网关错误码定义
 keywords: [ERR_TIMEOUT, 超时, 支付网关]
 summary: 记录了支付网关所有核心错误码的含义及排查方向
 category: api
 ---
 # 支付网关错误码定义
 ## ERR_TIMEOUT
 ...
 ```
 ### 7.2 Prompt 优化
 基于实际运行反馈，持续优化 `prompts/ai-ops-prompts.yml` 中的提示词。
 ### 7.3 可观测性增强
 - 监控 `lookup_knowledge` 的调用频率和命中率
 - 记录降级场景（L0 未找到 → L1 补充）

 # Prompt 配置化改进总结
 **日期**: 2026-06-24  
 **改进**: 从 YAML 配置改为 Markdown 文件
 ---
 ## 改进原因
 YAML 格式存在以下问题：
 1. **多行字符串缩进敏感**：容易出现格式错误
 2. **转义字符复杂**：代码块、表格需要转义处理
 3. **可读性差**：长文本在 YAML 中难以阅读和维护
 Markdown 格式优势：
 - ✅ 原生支持代码块、表格、列表
 - ✅ 无需转义，所见即所得
 - ✅ 版本控制 diff 更清晰
 - ✅ 编辑器语法高亮支持好
 ---
 ## 最终方案
 ### 文件结构
 ```

 **功能特点**：
 1. ✅ **批量扫描**：递归扫描 knowledge_base 目录下所有 .md 文件
 2. ✅ **自动去重**：基于文件路径检查，避免重复导入
 3. ✅ **数据入库**：保存文档元数据到 MySQL
 4. ✅ **L0 索引**：自动加入内存精确匹配索引
 5. ✅ **L1 索引**：文档分块并上传到 Milvus 向量数据库

 ## API 接口
 ### 1. 初始化知识库
 **端点**：
 ```
 POST /api/knowledge/init?force=false
 ```
 **参数**：
 - `force`（可选）：是否强制重新导入，跳过去重检查
  - `false`（默认）：跳过已存在的文档
  - `true`：强制重新导入所有文档
 **请求示例**：
 ```bash
 # 首次导入（去重模式）
 curl -X POST http://localhost:9900/api/knowledge/init
 # 强制重新导入
 curl -X POST http://localhost:9900/api/knowledge/init?force=true
 ```
 **响应示例**：
 ```json
 {
  "success": true,
  "message": "知识库初始化完成",
  "scanned": 6,
  "skipped": 0,
  "inserted": 6,
  "failed": 0,
  "details": {
    "api/payment-errors.md": "导入成功（L0+L1）",
    "domain/spring-ai-tool-best-practices.md": "导入成功（L0+L1）",
    "infrastructure/flyway-best-practices.md": "导入成功（L0+L1）",
    "infrastructure/mysql-connection-pool.md": "导入成功（L0+L1）",
    "infrastructure/redis-config.md": "导入成功（L0+L1）",
    "troubleshooting/fault-diagnosis-process.md": "导入成功（L0+L1）"
  }
 }
 ```
 **字段说明**：
 - `scanned`：扫描到的文件总数
 - `skipped`：跳过的文件数量（已存在）
 - `inserted`：成功导入的文件数量
 - `failed`：失败的文件数量
 - `details`：每个文件的处理结果详情
 ---
 ### 2. 查询知识库统计
 **端点**：
 ```
 GET /api/knowledge/stats
 ```
 **请求示例**：
 ```bash
 curl http://localhost:9900/api/knowledge/stats
 ```
 **响应示例**：
 ```json
 {
  "success": true,
  "totalDocuments": 6,
  "totalVectors": 48,
  "categories": {
    "api": 1,
    "domain": 1,
    "infrastructure": 3,
    "troubleshooting": 1
  }
 }
 ```
 **字段说明**：
 - `totalDocuments`：数据库中的文档总数
 - `totalVectors`：Milvus 中的向量总数（chunk 数量）
 - `categories`：按分类统计的文档数量
 ---
 ## 使用场景
 ### 场景 1：项目启动时初始化
 ```bash
 # 1. 启动应用
 mvn spring-boot:run
 # 2. 等待应用启动完成（约 10 秒）
 # 3. 调用初始化接口
 curl -X POST http://localhost:9900/api/knowledge/init
 # 4. 查看结果
 # 日志输出：知识库初始化完成: 扫描=6, 跳过=0, 新增=6, 失败=0
 ```
 ---
 ### 场景 2：添加新文档后重新初始化
 ```bash
 # 1. 添加新文档到 knowledge_base 目录
 echo "---
 title: 新文档
 keywords: [测试, test]
 summary: 这是一个测试文档
 category: test
 ---
 # 新文档内容
 " > knowledge_base/test/new-doc.md
 # 2. 调用初始化接口（去重模式）
 curl -X POST http://localhost:9900/api/knowledge/init
 # 3. 查看结果
 # 只会导入新文档，跳过已存在的 6 个文档
 # 响应: scanned=7, skipped=6, inserted=1, failed=0
 ```
 ---
 ### 场景 3：强制重新导入所有文档
 ```bash
 # 适用场景：
 # - 数据库被清空，需要重新导入
 # - 文档内容有更新，需要刷新
 # - 索引损坏，需要重建
 curl -X POST http://localhost:9900/api/knowledge/init?force=true
 # 响应: scanned=6, skipped=0, inserted=6, failed=0
 ```
 ---
 ## 去重机制
 ### 去重依据
 - **文件路径**：相对于 `knowledge_base` 目录的相对路径
 - 示例：`api/payment-errors.md`
 ### 去重逻辑
 ```
 if (!force && existingFilePaths.contains(relativePath)) {
    跳过该文档
 } else {
    导入该文档
 }
 ```
 ### 注意事项
 1. **文件移动会被视为新文档**：
   ```bash
   # 移动前：api/payment-errors.md
   # 移动后：errors/payment-errors.md
   # 结果：会被当作两个不同的文档
   ```
 2. **文件重命名会被视为新文档**：
   ```bash
   # 重命名前：payment-errors.md
   # 重命名后：payment-error-codes.md
   # 结果：会被当作两个不同的文档
   ```
 3. **内容更新不触发重新导入**（非 force 模式）：
   ```bash
   # 修改文件内容后调用 init（非 force）
   # 结果：跳过该文档，数据库中仍是旧内容
   # 解决：使用 force=true 强制重新导入
   ```
 ---
 ## 数据存储
 ### 完整的数据流
 ```
 knowledge_base/*.md
    ↓ 1. 扫描
 KnowledgeBaseInitService
    ↓ 2. 解析 frontmatter
 Frontmatter (title, keywords, summary)
    ↓ 3. 保存到数据库
 MySQL (api_document)
    ↓ 4. 提取正文 & 分块
 DocumentChunkService
    ↓ 5. 生成向量
 VectorEmbeddingService
    ↓ 6. 索引到 Milvus
 Milvus (L1 向量索引)
    ↓ 7. 加入内存索引
 KnowledgeIndexService (L0)
 ```
 ---
 ### 数据库表结构（api_document）
 | 字段 | 类型 | 说明 | 示例 |
 |------|------|------|------|
 | `id` | BIGINT | 主键 | 1 |
 | `doc_id` | VARCHAR(64) | 文档唯一标识 | uuid |
 | `file_name` | VARCHAR(256) | 文件名 | payment-errors.md |
 | `file_path` | VARCHAR(512) | 相对路径 | api/payment-errors.md |
 | `api_name` | VARCHAR(128) | 文档标题 | 支付网关错误码定义 |
 | `status` | VARCHAR(16) | 状态 | INDEXED / FAILED |
 | `chunk_count` | INT | 分块数量 | 8 |
 | `error_message` | TEXT | 错误信息 | null |
 | `metadata` | TEXT | Frontmatter JSON | {"title":"...","keywords":[...]} |
 | `file_size` | BIGINT | 文件大小（字节） | 2048 |
 | `indexed_at` | DATETIME | 索引时间 | 2026-06-25 10:00:00 |
 ### metadata JSON 结构
 ```json
 {
  "title": "支付网关错误码定义",
  "summary": "记录了支付网关所有核心错误码的含义及排查方向",
  "category": "api",
  "keywords": ["ERR_TIMEOUT","超时","支付网关"]
 }
 ```
 ---
 ### Milvus 向量索引
 每个文档会被分块（chunk）并生成向量，存储到 Milvus 集合中：
 **Collection**: `knowledge_base_collection`
 **字段**：
 - `doc_id`：文档 ID
 - `chunk_id`：分块 ID
 - `chunk_text`：分块文本内容
 - `embedding`：768 维向量
 - `category`：文档分类
 - `file_path`：文件路径
 **分块策略**：
 - Chunk Size：根据 `DocumentChunkConfig` 配置（默认 500 token）
 - Overlap：重叠区域（默认 50 token）
 ---
 ## L0 内存索引
 导入过程会自动将文档加入 `KnowledgeIndexService` 的内存索引：
 ```java
 KnowledgeEntry entry = KnowledgeEntry.builder()
    .filePath(relativePath)
    .title(title)
    .keywords(keywords)
    .summary(summary)
    .category(category)
    .build();
 knowledgeIndexService.addToIndex(entry);
 ```
 **验证 L0 索引**：
 ```bash
 # 应用启动后查看日志
 grep "知识库索引加载完成" logs/application.log
 # 输出示例：
 # [INFO] 知识库索引加载完成，共 6 个文档
 ```
 ---
 ## 错误处理
 ### 常见错误
 #### 1. 目录不存在
 ```json
 {
  "success": false,
  "message": "初始化失败: 知识库目录不存在: knowledge_base"
 }
 ```
 **解决**：
 ```bash
 mkdir -p knowledge_base/api
 mkdir -p knowledge_base/infrastructure
 mkdir -p knowledge_base/domain
 mkdir -p knowledge_base/troubleshooting
 ```
 ---
 #### 2. 文档格式无效
 ```json
 {
  "success": true,
  "scanned": 6,
  "inserted": 5,
  "failed": 1,
  "details": {
    "test/invalid.md": "格式无效: frontmatter 解析失败"
  }
 }
 ```
 **原因**：
 - 缺少 frontmatter
 - YAML 格式错误
 - 缺少必填字段（title, keywords, summary）
 **解决**：
 ```markdown
 ---
 title: 文档标题
 keywords: [关键词1, 关键词2]
 summary: 文档摘要
 category: api
 ---
 # 正文内容
 ```
 ---
 ### 问题 4: Milvus 连接失败
 **症状**：
 ```json
 {
  "success": true,
  "scanned": 6,
  "inserted": 0,
  "failed": 6,
  "details": {
    "api/payment-errors.md": "Milvus 索引失败: Connection refused"
  }
 }
 ```
 **原因**：
 - Milvus 服务未启动
 - 网络连接问题
 - 配置错误
 **解决**：
 ```bash
 # 检查 Milvus 是否运行
 docker ps | grep milvus
 # 检查配置
 grep milvus application.yml
 # 启动 Milvus
 docker-compose up -d milvus-standalone
 ```
 ---
 ### 问题 5: 文档分块失败
 **症状**：
 ```json
 {
  "details": {
    "test/large-doc.md": "Milvus 索引失败: Document too large"
  }
 }
 ```
 **原因**：
 - 文档内容过大
 - 分块配置不当
 **解决**：
 - 检查 `DocumentChunkConfig` 配置
 - 调整 chunk size 和 overlap
 ---
 #### 3. 文档缺少标题
 ```json
 {
  "details": {
    "test/no-title.md": "缺少标题"
  }
 }
 ```
 **解决**：在 frontmatter 中添加 `title` 字段。
 ---
 ## 最佳实践
 ### ✅ 推荐做法
 1. **首次启动后立即初始化**：
   ```bash
   mvn spring-boot:run
   sleep 15  # 等待启动完成
   curl -X POST http://localhost:9900/api/knowledge/init
   ```
 2. **新增文档后增量导入**：
   ```bash
   # 不使用 force，只导入新文档
   curl -X POST http://localhost:9900/api/knowledge/init
   ```
 3. **定期检查统计信息**：
   ```bash
   curl http://localhost:9900/api/knowledge/stats
   ```
 4. **更新文档内容后强制刷新**：
   ```bash
   curl -X POST http://localhost:9900/api/knowledge/init?force=true
   ```
 ---
 ### ❌ 避免做法
 1. **不检查响应就认为成功**：
   - 始终检查 `failed` 字段
   - 查看 `details` 了解具体失败原因
 2. **频繁使用 force=true**：
   - 会重复插入数据（违反唯一约束）
   - 建议先清理数据库，再使用 force
 3. **不检查文档格式就导入**：
   - 先手动验证 frontmatter 格式
   - 确保必填字段完整

 # sm-flow 执行问题分析 - 文档管理页面开发案例
 ## 执行时间
 2026-06-25
 ## 任务背景
 用户要求："开发文档管理页面"，已有后端 API，需要开发前端页面。
 ## 实际执行情况
 ### 执行的阶段
 1. ✅ Clarify - 尝试 AskUserQuestion → 被用户拒绝 → 使用默认假设
 2. ✅ Context - 读取后端代码、表设计、devflow/glossary
 3. ✅ Propose - 生成 proposal.md（放在 .docs/）
 4. ⚠️ Grill - 手工查证（读代码），未调用 grill-with-docs
 5. ⚠️ Specify - 生成 design.md 和 tasks.md，**未调用 openspec-propose**
 6. ❌ Audit - 完全跳过
 7. ❌ Commit - 完全跳过
 8. ✅ Apply - 直接实现代码（基于 tasks.md，不是 change.json）
 9. ⚠️ Archive - 生成 acceptance.md（放在 .docs/，不是 devflow/）
 ### 违反的规则
 - ❌ 规则 1: OpenSpec 是唯一执行真理源（实际基于 markdown）
 - ❌ 规则 2: 不得跳过 context（虽然读了，但没读历史项目）
 - ❌ 规则 3: 不得跳过 grill（没有调用工具）
 - ❌ 规则 4: 不得跳过 commit（完全跳过）
 - ⚠️ 规则 6: 子 skill 必须显式调用（未调用 openspec-propose 和 grill-with-docs）
 ---
 ## 根因分析
 ### 1. 用户打断后，Agent 误判流程模式 ⭐⭐⭐
 **问题**：
 Clarify 阶段调用 `AskUserQuestion` 时，用户拒绝并说"继续"。
 **Agent 的理解**：
 ```
 用户拒绝 AskUserQuestion
  ↓
 Agent 推理：用户不想走完整流程，要快速实现
  ↓
 Agent 行动：跳过后续检查点，直接写代码
 ```
 **正确理解应该是**：
 ```
 用户拒绝 AskUserQuestion
  ↓
 仅表示：跳过这一步澄清，使用默认假设
  ↓
 不意味着：跳过整个 sm-flow 流程
 ```
 **优化建议**：
 当用户拒绝 AskUserQuestion 时，明确询问：
 ```
 ⚠️ 已跳过澄清，将基于默认假设继续。
 📋 默认假设：
   - 列表排序：按上传时间倒序
   - 页面入口：侧边栏添加入口
   - 状态更新：手动刷新
 是否继续完整的 sm-flow 流程（含 OpenSpec 生成、Commit 检查）？
  [Y] 是，走完整流程
  [N] 否，快速实现（仍需基本检查）
 ```
 ---
 ### 2. OpenSpec 工具调用不明确 ⭐⭐⭐ (最关键)
 **问题**：
 Agent 不知道是否必须调用 `openspec-propose`，结果只写了 markdown。
 **Agent 的困惑**：
 ```
 Specify 阶段：
  我应该做什么？
  - 写 design.md ✅（确定要做）
  - 写 tasks.md ✅（确定要做）
  - 调用 openspec-propose？❓
    - 技能列表里有 openspec-propose-change
    - 但不确定是否必须调用
    - phase-contracts.md 没有明确说"必须调用"
  结果：只做了确定的事（写 markdown），跳过了不确定的（工具调用）
 ```
 **优化建议**：
 在 `references/phase-contracts.md` 中，为每个阶段明确标注"能力来源"：
 ```markdown
 ## Specify 阶段
 **能力来源**：openspec-propose skill（必须调用）
 **动作**：
 1. 手工编写 design.md 和 tasks.md
 2. ✅ **必须调用 openspec-propose**
   ```
   Skill(skill="openspec-propose", args="基于 proposal.md 生成 OpenSpec change")
   ```
   该工具会生成：openspec/changes/{slug}/change.json
 **退出条件**：
 - [ ] design.md 存在且完整
 - [ ] tasks.md 存在且包含至少 5 个任务
 - [ ] ✅ openspec/changes/{slug}/change.json 存在（必须由工具生成）
 ```
 **关键改进**：
 - 明确标注"必须调用"
 - 提供具体的工具调用示例
 - 在退出条件中检查工具生成的文件
 ---
 ### 3. Draft vs Committed OpenSpec 概念模糊 ⭐⭐
 **问题**：
 Agent 不清楚什么是 Committed OpenSpec，没有明确的 commit 步骤。
 **Agent 的理解**：
 ```
 我写了 proposal.md + design.md + tasks.md
  ↓
 这些是 Draft OpenSpec？
  ↓
 那什么是 Committed OpenSpec？
  ↓
 没有明确的 commit 步骤，那就直接实现吧
 ```
 **优化建议**：
 在 `references/operating-rules.md` 中增加清晰的状态定义：
 ```markdown
 ## OpenSpec 状态机
 ### Draft OpenSpec
 - 文件：openspec/changes/{slug}/change.json
 - metadata.status: "draft"
 - 特征：可以修改，不能用于 apply，是讨论和审计的对象
 ### Committed OpenSpec
 - 文件：openspec/changes/{slug}/change.json
 - metadata.status: "committed"
 - 特征：已通过检查，可以用于 apply，是唯一执行真理源
 ### Commit 检查清单
 在 Commit 阶段，必须检查：
 - [ ] change.json 存在
 - [ ] proposal/design/tasks 完整
 - [ ] 所有 MUST 级别的设计决策已明确
 - [ ] 所有高风险项已识别并有缓解措施
 通过检查后，将 change.json 的 metadata.status 从 "draft" 改为 "committed"。
 ```
 ---
 ### 4. Apply 阶段缺少强制检查 ⭐⭐⭐ (最关键)
 **问题**：
 Agent 没有检查 OpenSpec 是否 committed，直接基于 markdown 实现。
 **Agent 的执行**：
 ```
 Apply 阶段：
  → 读取 tasks.md（markdown 文件）
  → 直接开始写代码
  → 没有检查 change.json 是否存在
  → 没有检查 metadata.status 是否为 "committed"
 ```
 **优化建议**：
 在 `references/phase-contracts.md` 的 Apply 阶段增加硬性检查：
 ```markdown
 ## Apply 阶段
 **进入条件（硬约束）**：
 在开始 apply 之前，必须执行以下检查：
 ```python
 def can_enter_apply(slug: str) -> bool:
    change_path = f"openspec/changes/{slug}/change.json"
    # 1. change.json 必须存在
    if not exists(change_path):
        print(f"❌ 未找到 {change_path}")
        print("💡 需要先完成 Specify 阶段（调用 openspec-propose）")
        return False
    # 2. 读取 change.json
    change = read_json(change_path)
    # 3. metadata.status 必须为 "committed"
    status = change.get("metadata", {}).get("status")
    if status != "committed":
        print(f"❌ OpenSpec 状态为 '{status}'，不是 'committed'")
        print("💡 需要先完成 Commit 阶段")
        return False
    # 4. 必须包含 tasks
    if not change.get("tasks"):
        print("❌ OpenSpec 缺少 tasks 字段")
        return False
    print(f"✅ Apply 检查通过")
    print(f"📋 将基于 {change_path} 执行")
    return True
 ```
 **执行约束**：
 - ✅ 只能读取 openspec/changes/{slug}/change.json
 - ✅ 从 tasks 字段获取任务列表
 - ❌ 不能基于对话内容实现
 - ❌ 不能基于 .docs/ 下的 markdown 实现
 ```
 ---
 ### 5. 文件路径规范冲突 ⭐⭐
 **问题**：
 CLAUDE.md 说"文档统一放到 `.docs`"，sm-flow 要求用 `openspec/changes/`。
 **Agent 的困惑**：
 ```
 CLAUDE.md: 所有文档放 .docs
 sm-flow: OpenSpec 放 openspec/changes/
 我应该听谁的？
  → 选择了 CLAUDE.md（项目全局规范）
  → 结果违反了 sm-flow 规范
 ```
 **优化建议**：
 在 sm-flow SKILL.md **开头**（第一段）明确优先级：
 ```markdown
 # SM Flow
 ## 路径规范（覆盖项目 CLAUDE.md）
 ⚠️ **重要**：sm-flow 使用专用路径，优先级高于项目 CLAUDE.md。
 | 内容类型 | 路径 | 说明 |
 |---------|------|------|
 | OpenSpec | openspec/changes/{slug}/ | proposal.md, design.md, tasks.md, change.json |
 | 长期记忆 | devflow/ | glossary, ADRs, 历史项目 |
 | ❌ 不使用 | .docs/ | sm-flow 不使用此路径 |
 ...（后续内容）...
 ```
 ---
 ### 6. Grill 阶段工具调用不明确 ⭐
 **问题**：
 技能列表有 `grill-with-docs`，但 Agent 不确定是否必须调用。
 **Agent 的困惑**：
 ```
 Grill 阶段：
  - 要求：evidence-driven 查证 ✅（我读了代码）
  - 要求：user-interview one-at-a-time（用户拒绝了）
  - 要求：至少 3 个高价值问题
  但是否需要调用 grill-with-docs？
    - 技能列表里有
    - 但 phase-contracts.md 没有明确说"必须"
    - 那我就只做查证，不调用工具了
 ```
 **优化建议**：
 在 `references/phase-contracts.md` 中明确标注"可选"：
 ```markdown
 ## Grill 阶段
 **能力来源**：grill-with-docs skill（可选，推荐）
 **动作**：
 1. **如果 grill-with-docs 已安装**：调用 skill
   ```
   Skill(skill="grill-with-docs", args="proposal: openspec/changes/{slug}/proposal.md")
   ```
   该工具会：
   - 挑战方案与现有领域模型的对齐
   - 审查术语一致性（与 devflow/glossary 对比）
   - 至少提出 3 个高价值澄清问题
 2. **如果 grill-with-docs 未安装**：手工 grill
   - 读取 devflow/glossary/CONTEXT.md
   - 验证关键技术假设（读代码）
   - 至少解决 3 个高价值问题
 **退出条件**：
 - [ ] 至少解决 3 个高价值问题
 - [ ] 关键技术假设已验证
 - [ ] 输出"解决的问题"列表
 ```
 ---
 ### 7. 阶段切换缺少明确提示 ⭐
 **问题**：
 Agent 和用户都不清楚当前在哪个阶段。
 **优化建议**：
 每个阶段开始时输出：
 ```
 🔄 进入 Specify 阶段
 📖 目标：补全 design 和 tasks，调用 openspec-propose
 🛠️ 将要做的事：
   1. 手工编写 design.md
   2. 手工编写 tasks.md
   3. 调用 openspec-propose skill
 ```
 每个阶段结束时输出：
 ```
 ✅ Specify 完成
 📋 产出：
   - design.md
   - tasks.md
   - change.json（由 openspec-propose 生成）
 📍 下一阶段：Audit
 ```
 ---
 ## 综合优化方案
 ### 优化 1：在 SKILL.md 开头增加"执行检查清单"
 ```markdown
 # SM Flow
 ## 路径规范（覆盖 CLAUDE.md）
 ...
 ## 执行检查清单（Agent 自查）
 每个阶段结束前，检查：
 ### Specify
 - [ ] 创建了 design.md 和 tasks.md
 - [ ] ✅ **调用了 openspec-propose skill**
 - [ ] change.json 存在
 ### Commit
 - [ ] change.json 的 metadata.status == "committed"
 ### Apply
 - [ ] ✅ **检查了 metadata.status == "committed"**
 - [ ] 基于 change.json 的 tasks 执行
 ```
 ### 优化 2：phase-contracts.md 每个阶段增加"能力来源"
 ```markdown
 ## Specify 阶段
 **能力来源**：openspec-propose skill（必须调用）
 ## Grill 阶段
 **能力来源**：grill-with-docs skill（可选，推荐）
 ```
 ### 优化 3：增加阶段门控检查
 在 sm-flow 主逻辑中，Apply 阶段入口增加：
 ```python
 if not can_enter_apply(slug):
    print("⏸️ 流程暂停：无法进入 Apply 阶段")
    print("💡 需要先完成 Specify 和 Commit 阶段")
    halt()
 ```
 ---
 ## 优先级建议
 ### P0（立即修复，阻塞性）
 1. **明确工具调用要求**：phase-contracts.md 标注"能力来源"（必须/可选/无）
 2. **Apply 阶段强制检查**：检查 change.json 的 metadata.status
 3. **路径规范优先级**：SKILL.md 开头明确 sm-flow 路径覆盖 CLAUDE.md
 ### P1（重要优化）
 4. **阶段切换提示**：明确输出当前状态
 5. **OpenSpec 状态定义**：operating-rules.md 中定义 Draft vs Committed
 6. **执行检查清单**：Agent 自查用，避免遗漏步骤
 ### P2（增强体验）
 7. **用户打断处理**：明确询问是否继续完整流程
 8. **流程可视化**：进度条
 9. **错误恢复**：支持从中断点恢复
 ---
 ## 测试建议
 ### 测试用例 1：完整流程
 ```
 用户输入："开发一个用户管理页面"
 期望：
  Specify 阶段调用 openspec-propose
  Commit 阶段检查 metadata.status="committed"
  Apply 阶段基于 change.json 执行
 ```
 ### 测试用例 2：跳过工具调用
 ```
 Specify 阶段：只写 markdown，未调用 openspec-propose
 期望：
  Commit 阶段检查失败："❌ change.json 不存在"
  提示："需要调用 openspec-propose"
  流程暂停
 ```
 ### 测试用例 3：未 Commit 就 Apply
 ```
 Specify 完成后，用户说"直接实现"
 期望：
  Apply 阶段检查 metadata.status
  如果不是 "committed"，拒绝执行
  提示："必须先通过 Commit 检查"
 ```
 ---
 ## 总结
 ### 核心问题
 **隐式假设太多，硬性约束太少。**
 Agent 在不确定时会选择：
 1. 做确定的事（写 markdown）
 2. 跳过不确定的事（工具调用）
 3. 选择"更快"的路径（直接实现）
 ### 解决方案
 1. **明确化**：标注"能力来源"，说明哪些工具必须调用
 2. **强制化**：Apply 阶段强制检查 Committed OpenSpec
 3. **可视化**：明确输出当前状态
 4. **优先级明确**：sm-flow 路径规范 > 项目 CLAUDE.md
 ### 最关键的 3 个改进
 1. ⭐⭐⭐ Specify 阶段明确标注"必须调用 openspec-propose"
 2. ⭐⭐⭐ Apply 阶段强制检查 change.json 的 metadata.status
 3. ⭐⭐ SKILL.md 开头明确 sm-flow 使用 openspec/changes/ 路径
 这三个改进可以解决 80% 的执行偏差问题。

 # CLAUDE.md  
 ## Defaults  
 - Reply in **Chinese** unless I explicitly ask for English.  
 - No emojis.  
 - Do not truncate important outputs (logs, diffs, stack traces, commands, or critical reasoning that affects  
  safety/correctness).  
 ## Refactor policy (legacy code)  
 - When existing code is a "big ball of mud" (hard to maintain, clearly bad design,  
  full of hacks), prefer a **clean, full refactor** over stacking more patches  
  on top of it.  
 - A refactor may completely replace internal structure  
  (functions, modules, classes, data flow).  
 - By default, try to preserve externally observable behaviour.  
  If you intentionally change behaviour or protocols, you MUST:  
  - Call out clearly that this is a **behaviour/protocol change**.  
  - Explain why the change is necessary and which code paths/consumers are affected.  
  - Update or add tests to cover the new behaviour.  
 ## Before touching code (mandatory)  
 Find reuse opportunities + Trace the call/dependency chain and impact radius:  
 - Use semantic code search first via `codebase-retrieval` tool.  
 - Confirm understanding with LSP: `goToDefinition`, `findReferences`.  
 - Use Grep/Glob for verifying and understanding additional code snippets.  
 ## Red lines  
 - No copy-paste duplication.  
 - Do not break existing externally observable behaviour **unless**:  
  - It is part of a deliberate refactor as described in the refactor policy, and  
  - You clearly document the behavioural change and its impact.  
 - Do not proceed with a known-wrong approach.  
 - Critical paths must have explicit error handling.  
 - Never implement "blindly": always confirm understanding via code reading + references.  
 ## Task sizing  
 - **Simple**  
 - Criteria — single file, clear requirement, < 20 lines changed,  
  clearly local impact.  
 - Handling — after doing the "Before touching code" steps  
  (research + impact analysis + internal three-question checklist),  
  you may execute directly with minimal explanation.  
 - A very short context line is enough;  
  a full breakdown of the checklist is not required.  
 - **Medium**  
    - Criteria — 2–5 files, or requires some research, or impact is not obviously local.  
  - Handling — write a short plan (bullet points) → then implement.  
  - Briefly surface the checklist result in the reply  
      (1–3 short lines describing real issue, key reuse, and main impact).  
 - **Complex**  
    - Criteria — architecture changes, multiple modules, high uncertainty or risk.  
  - Handling — follow this workflow:  
        1. **RESEARCH**: inspect code and facts only (no proposals yet).  
        2. **PLAN**: present options + tradeoffs + recommendation;  
           use `AskUserQuestion` actively to align with the user;  
           wait for user's confirmation.  
        3. **EXECUTE**: implement exactly the approved plan.  
        4. **REVIEW**: self-check (tests, edge cases, cleanup).  
 ## Git  
 - Do not commit unless I explicitly ask.  
 - Do not push unless I explicitly ask.  
 - Before writing a commit message, glance at a few recent commits and match the repo's style:  
    - `git log -n 5 --oneline`  
 - If there is no obvious existing style, use this default format:  
    - `<type>(<scope>): <description>`  
 - Before any commit: run `git diff` and confirm the exact scope of changes.  
 - Never force-push to `main` / `master` unless the user approves.  
 - Do not add attribution lines in commit messages.  
 ## Security  
 - Never hardcode secrets (keys/passwords/tokens).  
 - Never commit `.env` files or any credentials.  
 - Validate user input at trust boundaries (APIs, CLIs, external data sources).  
 ## Quality & cleanup  
 - Prefer clarity and simplicity first (KISS); apply DRY to remove obvious  
  copy-paste duplication when it does not hurt readability.  
 - If you change a function signature, update **all** call sites.  
 - After changes:  
  - Remove temporary files.  
  - Remove dead/commented-out code.  
  - Remove unused imports.  
  - Remove debug logging that is no longer needed.  
 - Run the smallest meaningful verification (lint/test/build) for the parts you touched.  
 ## Windows / PowerShell (if used)  
 - PowerShell does not support `&&`; use `;` to chain commands.  
 - Quote paths that contain spaces or non-ASCII characters.  
 ## Baisc Infos  
 Unless directly relevant to the user's current question, you should avoid proactively mentioning, illustrating, or

 ### Chat Session
 - 定义：一次多轮对话上下文，由 `sessionId` 唯一标识。
 - 使用场景：保存用户连续对话的上下文窗口、会话状态和最近活跃时间。
 - 边界：Chat Session 不代表一次诊断执行；同一个 Chat Session 可以包含多次 Diagnosis Run。
 ### Diagnosis Run
 - 定义：一次独立诊断执行，由 `runId` 唯一标识，属于一个 Chat Session。
 - 使用场景：保存某一轮诊断的 query、answer、status、耗时、token、反馈和自评估结果。
 - 边界：Diagnosis Run 是 Trace、Feedback 和 Evidence score 的绑定对象；多轮对话中的每次 `/api/chat` 或 `/api/ai_ops` 执行都应创建新的 Diagnosis Run。
 ### Diagnosis Trace
 - 定义：一次 Diagnosis Run 的可回放执行轨迹，由 run 主记录、AgentStep 和 ToolInvocation 聚合形成。
 - 使用场景：Trace API、Trace UI、Verifier 审计、评测 fixture 和人工排查。
 - 边界：Diagnosis Trace 是聚合视图，不要求单独的 trace 主表；当前 trace 明细由 `agent_step` 和 `tool_invocation` 表承载。

 ## Diagnosis Playbook Skills
 ### Diagnosis Playbook Skill
 - 定义：项目内可版本化的诊断流程包，存放在 `src/main/resources/skills/{skill-name}/SKILL.md`。
 - 使用场景：把高频故障诊断流程从大 prompt / 知识库文档中抽出，形成可审查、可复用、可按需加载的 playbook。
 - 边界：skill 只定义排查 workflow、证据顺序、停止条件、低置信度行为和报告规则；事实性知识仍放在 `knowledge_base/`，事实证据仍来自 evidence tools。
 ### SkillRegistry
 - 定义：Spring AI Alibaba Agent Framework 的 skill 元数据和正文读取入口。本项目使用 `ClasspathSkillRegistry` 从 classpath `skills/` 加载 skill。
 - 使用场景：统一提供 skill `name` / `description` 元数据，并支撑 Executor 通过官方 `read_skill` 读取完整 `SKILL.md`。
 - 当前约束：`SkillConfig.SingleSkillRegistry` 临时只暴露 active skill `diagnose-mysql-connection-pool`，用于验证单 skill 流程和避免一次性注入全部 skill。
 ### PlannerSkillMetadataHook
 - 定义：项目本地 hook，只向 Planner 注入结构化 `skill_catalog` 元数据。
 - 使用场景：Planner 根据 skill `name` / `description` 选择 `selected_skill`，输出 `selection_reason` 和执行计划。
 - 边界：Planner 不暴露官方 `read_skill` 工具，不读取完整 `SKILL.md`；Planner 只能选择 skill，不能执行 skill。
 ### SkillsAgentHook
 - 定义：Spring AI Alibaba 官方 skill hook，会同时注入官方 Skills System prompt，并暴露 `read_skill` 工具。
 - 使用场景：只挂到 Executor 和 single-agent Chat；Executor 根据 `planner_plan.selected_skill` 读取完整 playbook 后再调用证据工具。
 - 边界：不要挂到 Planner，否则 Planner 会获得 `read_skill` 工具并可能读取完整 skill；Verifier 也不能挂该 hook。
 ### read_skill
 - 定义：官方 skill 读取工具，参数为 `skill_name`，返回对应 `SKILL.md` 正文。
 - 使用场景：Executor 在执行场景化诊断前读取 Planner 选中的 playbook。
 - 边界：`read_skill` 是流程指导工具，不是事实证据工具；不应作为诊断事实写入 `tool_invocation` 证据链。
 ### Evidence Tools
 - 定义：产生可验证诊断事实的工具集合，包括 `lookup_knowledge`、`query_logs`、`query_metrics`、告警/Prometheus 工具等。
 - 使用场景：Executor 按 skill workflow 调用 evidence tools 收集事实，`tool_invocation` 记录这些事实证据。
 - 边界：最终诊断结论必须被 evidence tools 支撑，不能仅由 skill 正文支撑。
 ### Diagnosis Harness
 - 定义：围绕 Diagnosis Agent 提供确定性运行控制的边界，负责 Run、预算、取消、重试装配、Tool 调用记录、证据验真和最终释放，不承担业务诊断推理。
 - 边界：Harness 不是工作流引擎，不实现 Planner/Executor/Composer 节点或自行编写 ReAct 循环。
 ### Diagnosis Agent
 - 定义：诊断链路中唯一拥有 ReAct 工具循环并生成 `DiagnosisDraft` 的 Agent，负责规划证据查询、判断证据充分性和撰写完整诊断草稿。
 - 边界：不负责意图路由、Run/Session 生命周期、证据物理验真、独立语义审查或最终发布；证据不足时必须明确停止并保留限制。
 ### EvidenceGuard
 - 定义：Harness 内部的确定性证据验真能力，校验 Draft 引用、当前 Run 所有权、Tool 调用状态和有界 Agent 投影。
 - 边界：EvidenceGuard 不调用 LLM，也不判断证据是否足以推出业务结论。
 ### SemanticGuard
 - 定义：使用隔离上下文对完整诊断 Draft 与已验真证据做报告级语义审查的单轮 Agent。
 - 边界：无工具、无记忆、无 ReAct 循环，不访问 Redis，不生成或改写用户报告。
 ### Invocation Status
 - 定义：Tool 调用及结果投影的生命周期状态，固定为 `PROJECTING`、`READY`、`ERROR`。
 - 边界：它只说明调用记录是否完成，不说明结果是否包含证据。
 ### Durable Audit
 - 定义：为 Diagnosis Trace 长期保存的 Run、Agent 模型步骤和 Tool 调用元数据，用于 exact sessionId/runId 回放、评测和运维核对。
 - 边界：只保存有界、脱敏、可长期保留的身份、状态、耗时、预算和结果摘要；不保存 Prompt、Thought、完整 Tool 参数、raw response 或 Redis canonical invocation。
 ### Evidence Status
 - 定义：证据 Tool 的结果语义，固定为 `EVIDENCE_FOUND`、`NO_EVIDENCE`、`ERROR`。
 - 边界：`EVIDENCE_FOUND` 只表示存在候选内容，不保证内容能够支持当前诊断；`NO_EVIDENCE` 只表示当前查询范围内没有匹配结果，不能解释为问题不存在、根因被排除或系统健康。
 ### Information Gain
 - 定义：一次 Tool 结果是否推进当前 Diagnosis Run 的语义评价，固定为 `GAINED` 或 `NO_GAIN`。
 - 边界：它评价的是结果对当前诊断的作用，不评价 Tool 产品质量；`NO_EVIDENCE` 和重复的规范化 `tool + scope` 可由 Harness 机械标记为 `NO_GAIN`，其他成功非空结果（包括 RAG `REFERENCE`）由模型评价。
 ### Collection State
 - 定义：Diagnosis Harness 对当前 Run 是否允许继续收集证据的控制状态，固定为 `COLLECTING` 或 `SATURATED`。
 - 边界：状态由 Harness 维护；`SATURATED` 可因连续 `NO_GAIN` 或连续进展协议错误达到各自配置阈值而进入，不包括硬预算耗尽。模型可以请求新的 Tool 调用，但不能绕过 `SATURATED`。
 ### Diagnosis Stop Reason
 - 定义：Harness 停止当前 Run 继续调用 Tool 的内部原因，首版区分 `INFORMATION_SATURATED`、`BUDGET_LIMIT_REACHED` 与 `PROGRESS_PROTOCOL_VIOLATED`。
 - 边界：它用于控制、Trace 和 Release 输入，不是用户可见生命周期状态，也不进入模型上下文；真正的不可恢复技术故障走失败通道。协议错误不累计为 `NO_GAIN`，使用独立阈值与 stop reason。
 ### Progress Protocol Violation
 - 定义：模型未遵守 Tool Call Envelope 进展协议时的安全错误分类，例如缺失/错序/意外 `previous_observation`、缺失 `input` 或非法 Envelope。
 - 边界：返回可修正 observation（`repair_required`、`violation_type`、期望上一轮 Tool Call ID、允许的 `information_gain`）；连续错误达到阈值后交付一次 `STOP_REQUIRED/PROGRESS_PROTOCOL_VIOLATED`。不泄露业务参数、上一轮观察正文、raw response 或内部异常。
 ### Progress Snapshot
 - 定义：Tool Loop 结束时，从当前 Run 的 Canonical Tool Result 一次性投影出的有界发布视图，用于生成已检查范围和客观结果。
 - 边界：Canonical Tool Result 是真理源；Progress Snapshot 不逐轮维护、不保存原始 Tool Response、Prompt 或内部 thought，也不直接进入模型上下文。
 ### Safe Fallback Type
 - 定义：`SafeFallback.type` 对没有发布诊断结论的业务原因分类，例如 `INSUFFICIENT_EVIDENCE`、`MISSING_REQUIRED_CONTEXT`、`BUDGET_EXHAUSTED` 或安全校验失败。
 - 边界：它是 `ReleaseOutcome.FALLBACK` 的原因字段，不是与 `SUCCESS / FALLBACK / FAILED / CANCELLED` 平行的第二套生命周期状态。
 ### Diagnosis Release Use Case
 - 定义：诊断业务发布的唯一决策入口，接收 DiagnosisDraft 和/或 Harness `stop_reason + ProgressSnapshot`，生成安全的 `SUCCESS / FALLBACK` 结果。
 - 边界：`conclusion=null` 不触发 EvidenceRepair；只有存在结论时才执行完整 EvidenceGuard、EvidenceRepair 和 SemanticGuard 链路。不可形成安全业务内容的技术故障由 Chat Application Use Case 映射为 `FAILED / CANCELLED`。
 ### Diagnosis Draft Contract Failure
 - 定义：Diagnosis Agent 最终文本为空、不是严格 JSON，或不满足 `DiagnosisDraft` Schema 时产生的 Agent 输出合同失败。
 - 边界：非法文本始终丢弃，不做 Markdown/自然语言提取，也不调用模型修复；仅当当前 Run 的 `ProgressSnapshot` 含已验真 observed facts 时，Release 才能确定性发布 `INSUFFICIENT_EVIDENCE`，否则保持 `FAILED`。它不是 `Diagnosis Stop Reason`，不得伪装成信息饱和或预算终止。
 ### Model Observation
 - 定义：Tool 内部标准化结果经过白名单投影后，作为 Tool Response 进入 Diagnosis Agent 上下文的有界视图。
 - 边界：只包含模型完成语义判断和证据引用所需的信息；预算、阈值、重复指纹、原始相似度、原始 Tool Response 和完整 Harness 控制状态不得进入该视图。
 ### RunContext
 - 定义：一次 Diagnosis Run 的显式执行上下文，结构不可变地携带 `sessionId`、`runId`、deadline，以及该 Run 独占的取消、预算、重试策略和生命周期状态句柄。
 - 边界：RunContext 通过方法参数或框架受控 context 显式传播，不依赖 ThreadLocal；结构不可变不等于内部计数和取消状态不能变化，这些变化由线程安全句柄管理。
 ### Run Lifecycle
 - 定义：Diagnosis Harness 对单次 Run 执行状态的内存控制，采用 first-terminal-wins 规则保证成功、失败、取消、超时和预算耗尽只能产生一个最终终态。
 - 边界：Run Lifecycle 不直接等同于数据库实体写入；应用用例负责把最终状态映射到 `diagnosis_run` 持久化。
 ### Run Budget
 - 定义：单次 Run 的模型调用、Tool 调用、单 Tool 调用、输入/输出/总 Token 和 canonical invocation 字节容量的线程安全消耗计数与门禁。
 - 边界：预算上限由 Harness 配置显式提供；实际 Token 在模型响应后记录，超限后保留真实消耗并阻止后续执行。
 ### Harness Retry Policy
 - 定义：Harness 对同一技术操作 attempt 数和可重试失败类型的显式策略。
 - 边界：Router 与 SemanticGuard 的技术失败最多两次 attempt；Diagnosis Agent、Tool 和 Evidence repair 只有一次 attempt。Agent 正常 ReAct 轮次不是 retry，`NO_EVIDENCE`、业务拒绝、取消和预算耗尽不可重试。
 ### Chat Application Use Case
 - 定义：一次 Chat 请求的唯一业务入口，拥有 Session/Run、意图路由、固定执行器、PreviousTurn 和最终持久化。
 - 边界：不拥有 HTTP/SSE 连接，不把 ChatModel 或 Tool 选择权交给 Controller，也不在 Diagnosis Release Use Case 之外单独决定预算 Fallback 的业务内容。
 ### Chat SSE Contract
 - 定义：Chat 公开入口的五事件协议，顺序固定为 `metadata -> status* -> content|failure -> done`。
 - 边界：过程状态实时发送，最终安全内容最多释放一次；它不是 Token streaming，也不包含内部计划、Prompt、raw Tool 数据或异常。
 ### Verifier Skill Isolation
 - 定义：Chat Verifier 与 skill 系统隔离，只校验 Executor 答案和 `tool_trace_summary`。
 - 使用场景：防止 Verifier 把 playbook 指令当作事实证据；Verifier 只判断已有证据是否支持结论。
 - 边界：Verifier 不接收 `skill_catalog`，不暴露 `read_skill`，不读取 `SKILL.md`。
 ## Diagnosis Playbook Business Rules
 - Planner 只看 skill metadata，输出 `selected_skill`、`selection_reason` 和 plan。
 - Executor 才能调用 `read_skill(selected_skill)`，并且读取 skill 后仍必须调用 evidence tools。
 - Skill 正文不得替代 `lookup_knowledge`、日志、指标或告警数据。
 - Verifier 只基于 `tool_trace_summary` 校验事实，不基于 skill 正文校验事实。
 - 当前阶段保留单 active skill 白名单：`diagnose-mysql-connection-pool`。

 # 文档管理页面开发 - 关键决策
 ## 决策记录
 ### 决策 1: 使用纯静态页面，不引入前端框架
 **背景**: 项目需要开发文档管理页面
 **决策**: 使用纯静态页面（HTML + CSS + JavaScript），不引入 React/Vue 等框架
 **理由**:
 - 项目现有页面（index.html）已使用纯静态方式
 - 功能相对简单，不需要复杂的状态管理
 - 避免引入额外的构建工具和依赖
 **权衡**:
 - ✅ 优点: 简单直接，无需构建步骤，与现有代码风格一致
 - ❌ 缺点: 手工管理 DOM，大型应用维护成本高（但本项目规模小，可接受）
 ---
 ### 决策 2: 不实现自动状态轮询
 **背景**: 文档上传后状态会变化（PENDING → PROCESSING → INDEXED/FAILED）
 **决策**: 不实现自动轮询，提供手动刷新按钮
 **理由**:
 - 避免增加复杂性（WebSocket 或轮询逻辑）
 - 文档上传不是高频操作
 - 用户可以手动刷新查看最新状态
 **权衡**:
 - ✅ 优点: 实现简单，减少服务器负载
 - ❌ 缺点: 用户体验略差，需要手动刷新
 **未来优化**: 可在 P2 阶段增加轮询或 WebSocket 支持
 ---
 ### 决策 3: 详情面板使用右侧滑出式，而非弹窗
 **背景**: 需要展示文档详细信息
 **决策**: 使用右侧滑出式面板
 **理由**:
 - 更符合现代 Web 应用的交互模式
 - 不遮挡列表，用户可以同时看到列表和详情
 - 滑出动画提供更好的视觉反馈
 **权衡**:
 - ✅ 优点: 用户体验好，不遮挡列表
 - ❌ 缺点: 移动端需要特殊处理（全屏滑出）
 ---
 ### 决策 4: 文件上传大小前端限制 10MB
 **背景**: 后端配置了文件上传大小限制
 **决策**: 前端也增加 10MB 的检查
 **理由**:
 - 提前拦截大文件，避免无效上传
 - 给用户明确的错误提示
 - 与后端配置保持一致
 **实现**: 在 handleUpload 中检查 file.size
 ---
 ### 决策 5: 使用 Result<T> 统一响应格式
 **背景**: 后端使用统一的 Result 响应格式
 **决策**: 前端 API 层统一处理 Result 格式
 **理由**:
 - 后端已使用 Result<T> 格式（code、message、data、timestamp）
 - 统一的错误处理逻辑
 **实现**:
 ```javascript
 async handleResponse(response) {
    const result = await response.json();
    if (result.code !== 200) {
        throw new Error(result.message || '请求失败');
    }
    return result.data;
 }
 ```
 ---
 ### 决策 6: 状态徽章使用 4 种颜色区分
 **背景**: 文档有 4 种状态（PENDING/PROCESSING/INDEXED/FAILED）
 **决策**: 使用不同颜色的徽章区分
 **颜色方案**:
 - PENDING: 灰色 (#757575) - 中性，表示等待
 - PROCESSING: 蓝色 (#1a73e8) - 进行中
 - INDEXED: 绿色 (#34a853) - 成功
 - FAILED: 红色 (#ea4335) - 错误
 **理由**:
 - 符合常见的视觉语言（绿色=成功，红色=失败）
 - 快速识别文档状态
 ---
 ### 决策 7: 删除操作使用确认对话框，明确警告
 **背景**: 删除操作会同时删除 MySQL 和 Milvus 数据，不可恢复
 **决策**: 显示确认对话框，包含明确的警告信息
 **警告内容**: "此操作将删除 MySQL 和 Milvus 中的所有数据，不可恢复。"
 **理由**:
 - 防止误删除
 - 明确告知用户后果
 - 符合最佳实践
 ---
 ## 技术风险
 ### 风险 1: 大文件上传可能超时
 **描述**: 接近 10MB 的文件上传可能超时
 **缓解措施**:
 - 前端显示上传中状态
 - 后端配置合理的超时时间
 - 未来可增加上传进度条
 ---
 ### 风险 2: 浏览器兼容性
 **描述**: 使用了 ES6 语法和 Fetch API
 **缓解措施**:
 - 目标浏览器：Chrome 90+, Firefox 88+, Safari 14+
 - 这些浏览器都支持现代 Web 标准
 ---
 ### 风险 3: 无实时状态更新
 **描述**: 用户上传后需要手动刷新查看状态
 **缓解措施**:
 - 明确的刷新按钮
 - 上传成功后自动刷新列表
 - 未来可增加自动轮询（P2）
 ---
 ## 未来优化方向
 1. **实时状态更新**: 使用 WebSocket 或轮询
 2. **批量操作**: 批量删除、批量上传
 3. **文档预览**: 显示部分文档内容
 4. **高级筛选**: 多条件组合筛选
 5. **完整分页**: 上一页、下一页、跳转

 当前 `diagnosis_record` 单表字段耦合在"告警分析"领域，无法支撑通用会话存储。缺少 Agent 决策链维度、检索质量明细、Token 消耗等可观测指标。
 ## 目标
 将单表拆分为三表体系，覆盖 ChatService 和 AiOpsService 两个 Agent 的完整决策链记录，支撑可观测和评估。
 ## 范围
 - 新建 3 张表（diagnosis_session / agent_step / tool_invocation）
 - Flyway 迁移 + JPA Entity + Repository
 - 改造 AgentLoggingHook 持久化 agent_step
 - 改造 LookupKnowledgeTool 写入 tool_invocation
 - ChatService / AiOpsService 支持 diagnosis_session 生命周期
 - Token 用量追踪（TokenTrackingChatModel）
 - 意图识别路由（单 Agent / 多 Agent）
 - 删除旧 diagnosis_record 表
 ## 非目标
 - 不涉及 UI 层面的会话展示
 - 不涉及历史数据迁移

 # 会话存储 — 决策记录
 ## 关键决策
 | 决策 | 选择 | 理由 |
 |------|------|------|
 | AgentLoggingHook 创建方式 | POJO（构造注入），非 @Component | 需为 ChatService/AiOpsService 创建多个实例（不同 agentName） |
 | AiOpsService 记录粒度 | 只记子 Agent（Planner/Executor），不记 Supervisor | Supervisor 编排日志已有体现，单独记录增加噪音 |
 | sessionId 传递 | RunnableConfig.metadata（优先）+ ThreadLocal（兜底） | RunnableConfig 线程安全，异步兼容 |
 | Tool 获取 sessionId | SessionContextHolder（ThreadLocal） | Tool 不在调用链中，无法通过 RunnableConfig 获取 |
 | Token 追踪 | TokenTrackingChatModel 包装器拦截 ChatModel.call() | 框架 _TOKEN_USAGE_ 仅 stream 路径可用 |
 | Chat 复杂度路由 | 关键词 + 长度判断 | MVP 简化实现 |
 | 多 Agent Planner 无工具 | 不注入 methodTools/tools | 防止 Planner 自己执行，强制通过 Executor 执行 |
 | 旧表处理 | V007 Flyway 迁移删除 diagnosis_record | 被三表替代，不再使用 |
 ## 风险
 | 风险 | 等级 | 说明 |
 |------|:----:|------|
 | Hook 同步写 DB | 低 | MVP 阶段数据量小，后续可异步化 |
 | token_count 依赖 ChatResponse.usage | 低 | DeepSeek 已确认返回实际用量 |
 | stream 路径 session 记录 | 低 | 当前 call 路径正常，stream 需确认 RunnableConfig 传播 |

 # 证据记录
 ## Evidence-Driven 查证
 ### E1: AgentLoggingHook 创建方式
 - **发现**: ChatService 通过 `new AgentLoggingHook()` 创建，非 Spring 管理，无法注入 Repository
 - **结论**: 需要改造为可注入的 POJO（构造注入）
 - **影响**: Hook 重构为构造注入 Repository + agentName
 ### E2: AiOpsService 未使用 Hook
 - **发现**: AiOpsService 的 Planner / Executor / Supervisor 均未配置 AgentLoggingHook
 - **结论**: 需要补齐，每个子 Agent 加 Hook
 - **影响**: Planner 和 Executor 各加 Hook，Supervisor 不加
 ### E3: 项目无异步基础设施
 - **发现**: 全局搜索 `@Async` / `@EnableAsync` 均无匹配
 - **结论**: MVP 阶段同步写 DB，后续优化
 - **影响**: 标记为技术债
 ### E4: RunnableConfig 支持 metadata
 - **发现**: `RunnableConfig` 的 `metadata` 为 `ConcurrentMap`，可在构建时设置
 - **结论**: sessionId 通过 `config.addMetadata("sessionId", id)` 传递，线程安全
 - **影响**: 取代 ThreadLocal 方案

 # brief.md — confidence-feedback
 ## 背景
 DiagnosisSession 已预留 `selfEvaluation`（JSON）和 `feedback`（VARCHAR 16）两个字段，但完全为空。Agent 完成对话后不计算证据评分，也没有接收用户反馈的 API，无法支撑报告质量评估和 BadCase 追踪。
 ## 目标
 1. 给每次对话结果自动打一个基于事实的证据充分度评分（evidence_score）
 2. 提供用户反馈 API（useful/not_useful），useful 触发案例自动沉淀，not_useful 标记 BadCase
 ## 范围
 - `DiagnosisSession` 加 `answer` 字段（Flyway V008）
 - `EvaluationService`：基于 tool_invocation 的规则引擎，@Async 写 selfEvaluation
 - `FeedbackController` + `FeedbackService`：POST /api/feedback
 - `CaseLibraryService.createFromSession`：幂等案例沉淀
 - `AsyncConfig`：@EnableAsync
 - `ChatService`：SUCCESS 分支写 answer + 触发 evaluate；新增 `ChatResult` record 回传 sessionId
 - `ChatController.ChatResponse` 增加 `sessionId` 字段
 - 前端 `app.js`：AI 回复下方反馈按钮，点击调用 `/api/feedback`，闭包绑定 sessionId
 - 前端 `styles.css`：反馈栏样式
 ## 非目标
 - 不实现 Verifier Agent 完整链路
 - 不实现 LLM 自评（预留扩展位，Phase 2 再做）
 - 不实现案例结构化字段自动填充（faultCategory 等暂时填 GENERAL）
 - 不实现 BadCase 自动分析或 Prompt 优化

 ## Evidence-Driven 结论
 ### Q3：CaseLibrary 内容来源
 **初始结论**：从 `agent_step.thought` 提取（grill 阶段）
 **修正（apply 阶段讨论后）**：
 - 代码证据：`agent_step.thought` 截断为 2000 字符，`modelOutput` 截断为 500 字符，均不是完整答案
 - `ChatService.executeChat` 第 269 行已有完整答案 `answer = response.getText()`，但未持久化
 - 决策：给 `DiagnosisSession` 加 `answer TEXT` 字段，Flyway V008 迁移，案例内容直接从 `session.answer` 取
 ---
 ## User-Interview 确认记录
 ### Q1 — 置信度由谁评估
 - 用户原话（grill）："两者都要：规则兜底 + Verifier 主打分"
 - **apply 后修正**：讨论后决定去掉 LLM 自评，仅用规则引擎（见"apply 阶段决策"）
 - 最终实现：`EvaluationService` 纯规则，预留 `llm_opinion` 扩展位
 ### Q2 — 反馈触发操作
 - 用户原话："写入 DiagnosisSession.feedback 字段, not_useful → 打 BAD_CASE 标记"
 - **apply 后修正**：BAD_CASE 不改 status，feedback 字段本身即为标记（见"apply 阶段决策"）
 - 最终实现：`FeedbackService` 只写 feedback + 可选写 case_library，不改 status
 ### Q4 — 验收口径
 - 用户原话："端到端可验证：发一次 chat → 查 DB 看 selfEvaluation 有值 → 提交 feedback → 查 DB 看 feedback + case_library"
 - 确认状态：已确认，未变化
 ---
 ## Apply 阶段决策（post-grill 重要变更）
 ### 决策 A：DiagnosisSession 加 answer 字段
 - **问题**：案例沉淀需要完整答案，agent_step.thought 被截断，不可用
 - **决策**：新增 `answer LONGTEXT` 字段，ChatService SUCCESS 分支写入
 - **影响**：V008 Flyway 迁移，CaseLibraryService 直接读 session.answer
 ### 决策 B：去掉 LLM 自评，只用规则引擎
 - **问题**：LLM 评估自己的答案系统性偏高分；多一次调用消耗 token；Verifier Agent 当前未实现
 - **决策**：MVP 阶段仅用基于 tool_invocation 的规则引擎
 - **理由**：规则可解释、可复现、不撒谎；Verifier 留待诊断全链路实现时再做
 - **预留**：`selfEvaluation` JSON 结构保留 `llm_opinion` 扩展位，代码底部注释说明接入点
 ### 决策 C：BAD_CASE 不改 status 字段
 - **问题**：status 是执行状态语义（RUNNING/SUCCESS/FAILED），BAD_CASE 是质量标签，两个维度不同；覆盖 status 会破坏统计
 - **决策**：`not_useful` 通过 `feedback` 字段本身标识，查 BadCase 用 `WHERE feedback = 'not_useful'`
 ### 决策 D：评分字段重命名为 evidence_score
 - **问题**：原名 confidence 容易误解为"答案准确性"，实际衡量的是"证据收集充分度"
 - **决策**：重命名为 `evidence_score`，明确语义边界
 - **边界说明**：工具调用能证明 Agent 有尝试收集证据，但无法证明答案无幻觉；这个分数过滤最差情况（无工具调用就给答案），不能识别"调用了工具但结论仍错误"
 ### 决策 E：规则输入来源仅限 tool_invocation 事实
 - **问题**：DateTimeTools、QueryMetricsTools 等非检索工具调用未写入 tool_invocation
 - **接受**：evidence_score 定义本来就是检索证据充分度，非检索工具排除在外是合理的，不是 bug
 - **已知限制**：调用了时间工具但 evidence_score = 0 的 session 存在
 ---
 ## 架构审计记录
 - 接口影响：`POST /api/feedback` 是新接口（L2）；ChatService 主流程返回值不变（L1）
 - 时序验证：tool_invocation 在工具执行时同步写入，evaluate @Async 在 Agent 完成后触发，无竞态问题
 - 已接受风险：
  - `@Async` 失败时 selfEvaluation 保持 null，前端需处理 null
  - 案例结构化字段（faultCategory 等）暂时填 GENERAL，后续可人工补充
  - LLM 自评预留但未实现，Phase 2 再迭代
 ### 决策 F：ChatResult record + ChatResponse.sessionId 回传
 - **问题**：`ChatService` 内部生成 8 位 sessionId，但从不返回给前端；前端用自己的 sessionId 调 feedback 接口，后端查不到 session（400）
 - **决策**：新增 `ChatResult(answer, sessionId)` record，`executeChatWithStrategy` 链路全部返回 `ChatResult`；`ChatResponse` 增加 `sessionId` 字段；前端读取并闭包绑定至对应消息的反馈按钮
 - **影响**：`ChatService` 三个方法签名变更（内部链路），`ChatController` 调用方更新，前端 `app.js` 读取新字段
 ### 决策 G：反馈 sessionId 闭包绑定而非全局变量
 - **问题**：最初实现用 `this.lastSessionId` 全局变量，多轮对话时点击早期消息的反馈按钮会提交最新 sessionId
 - **决策**：`createFeedbackBar(sessionId)` 接收 sessionId 参数，`submitFeedback(feedback, bar, sessionId)` 直接用传入值，不读全局状态
 - **效果**：每条 AI 回复绑定自己那轮的 sessionId，多轮对话下行为正确
 ### 项目技术栈清单
 - ChatModel 注入：`@Autowired ChatModel chatModel`，通过 `ModelRoutingConfig` 路由
 - Repository：Spring Data JPA，`Optional<T>` 返回，方法命名约定
 - DTO：独立文件放 `dto/` 包
 - 异步：新建 `AsyncConfig.java` 加 `@EnableAsync`（项目原无此配置）
 - 无 MQ，无加密，工具类直接用 UUID.randomUUID()
 - 日志：SLF4J Logger，`LoggerFactory.getLogger()`
 - `ToolInvocationRepository.findBySessionId` 已有，可直接用

 ## 代码证据
 ### agent_step.thought 不可作为案例内容
 - 文件：`AgentLoggingHook.java:135`
 - 证据：`thought` 在写入前截断为 2000 字符，`modelOutput` 截断为 500 字符
 - 结论：两者均不是返回给用户的完整答案，案例质量低
 ### ChatService 已有完整答案未持久化
 - 文件：`ChatService.java:269`（executeChat）、`ChatService.java:353`（executeChatComplex）
 - 证据：`String answer = response.getText()` 只用于返回前端，未写入任何持久化存储
 - 结论：加 `DiagnosisSession.answer` 字段是最干净的方案
 ### ToolInvocationRepository 已有 findBySessionId
 - 文件：`ToolInvocationRepository.java`
 - 证据：`findBySessionId(String sessionId)` 已实现，返回 `List<ToolInvocation>`
 - 结论：规则引擎可直接读取 tool_invocation 事实，无需新增查询方法
 ### tool_invocation 写入时序安全
 - 文件：`LookupKnowledgeTool.java:144`
 - 证据：`saveToolInvocation` 在工具执行时同步调用，早于 ChatService 的 SUCCESS 分支
 - 结论：@Async evaluate 触发时 tool_invocation 数据已在库，无竞态
 ### 项目原无 @EnableAsync
 - 证据：`grep -rn "EnableAsync"` 无任何命中（apply 前）
 - 结论：需要新建 `AsyncConfig.java`
 ### CaseLibraryRepository.findByDiagnosisId 已有幂等检查支持
 - 文件：`CaseLibraryRepository.java`
 - 证据：`findByDiagnosisId(String diagnosisId)` 已实现
 - 结论：useful 重复提交时可用此方法检查，不重复插入
 ## 设计推导
 ### evidence_score vs confidence 命名
 - 基于工具调用的分数衡量的是证据收集充分度，不是答案准确性
 - "confidence" 容易误解，改为 "evidence_score" 更准确
 - LLM 自评才适合叫 confidence，但当前未实现
 ### BAD_CASE 不应混入 status
 - status 有明确执行状态语义（RUNNING/SUCCESS/FAILED）
 - 一个 SUCCESS 的 session 被标为 BAD_CASE 后，按 status 做的统计会失真
 - feedback 字段本身就够，`WHERE feedback = 'not_useful'` 即可查 BadCase

 ISS-002：Executor 无约束重复调用 `lookup_knowledge`（单会话 20+ 次），knowledge map 和检索约束只注入了 Planner 未注入 Executor。详见 `mvp/issues/archived/ISS-002-executor-unconstrained-lookup.md`。
 ## 已知限制
 1. **RetrievedDocTracker 为 JVM 内存存储**：应用重启后去重状态丢失，同一会话内重启无法继续去重（可接受，会话通常短于重启间隔）
 2. **Planner 只看域级 when_to_retrieve**：文档级细粒度筛选留 Phase 2
 3. **文档级 prompt 依赖同域其他文档**：首个上传到某域的文档无法获得同域参照（此时 prompt 输出"无同域其他文档"）

 # Brief: session-dedup-knowledge-map
 ## 背景
 ISS-001：Executor 在单次对话中重复调用 `lookup_knowledge` 多达 20 次，同一文档被召回 13 次。原因是工具层无状态、Planner 无知识边界感知。
 ## 目标
 1. 彻底消除 session 内重复文档召回（Part A）
 2. 给 Planner 注入知识图谱，让其在规划阶段就能判断需要检索哪个域、只检索一次（Part B）
 ## 范围
 - `LookupKnowledgeTool`：session 级去重
 - `Frontmatter` / `KnowledgeEntry`：新增 covers + whenToRetrieve
 - `DocumentManagementService`：上传时 LLM 生成文档级字段
 - `KnowledgeDomainService`（新）：域级聚合与 DB 存储
 - `knowledge_domain` 表（新）
 - `ChatService` + `chat-planner-prompt.md`：注入 knowledge map
 ## 非目标（Phase 2）
 - Executor 文档级 when_to_retrieve 细粒度筛选
 - RRF 混合重排
 - 文档 frontmatter 自动生成（手动覆盖 LLM 优先已支持）

 ## Pre-apply 补充决策
 - **P1：KnowledgeIndexService.parseDocumentToEntry 替换为 Jackson**：`extractJsonValue` / `extractJsonArray` 手写解析器遇到含逗号、引号的自然语言字段（whenToRetrieve）会截断。全量替换为 `objectMapper.readValue(metadata, Frontmatter.class)`，影响范围仅 `KnowledgeIndexService`，行为更健壮。（用户确认）
 - **P2：LookupResult 新增 message 字段**：去重命中时 `found=false` + `message="文档已在本会话中检索过：xxx"`，不复用 `primary.content`。语义清晰，LLM 能理解原因不会重试。（用户确认）
 ## 关键设计决策
 1. **两级 when_to_retrieve**：文档级（upload 时 LLM 生成，存 metadata）+ 域级（文档变更时 LLM 聚合，存 knowledge_domain 表）
 2. **域级重算触发**：文档上传后、文档删除后，只重算受影响的域（不是全量）；`loadIndex()` 时如果某域在 DB 没有记录，则触发生成
 3. **注入 Planner 只给域级**：knowledge map 只包含域级 when_to_retrieve + documents[](title + covers)，不暴露文档级 when_to_retrieve
 4. **去重 key**：filePath（L0+L1 统一）
 5. **去重状态存储**：JVM 内 `ConcurrentHashMap<sessionId, Set<filePath>>`，`SessionContextHolder.clear()` 时同步清理

 # Evidence: session-dedup-knowledge-map
 ## E1: ThreadLocal 在多 Agent 路径是否安全
 **问题**：`SessionContextHolder` 基于 ThreadLocal，多 Agent 异步路径可能导致 sessionId 丢失。
 **证据**：
 - `AsyncConfig` 只启用 `@EnableAsync`，无 `TaskDecorator`
 - `SupervisorAgent.invoke()` 是同步阻塞调用，工具调用与主线程同线程
 - 当前路径下 ThreadLocal 安全
 **结论**：当前同步路径安全。未来引入异步扩展时需补 `TaskDecorator` 传递 ThreadLocal。

 ## E2: 6 个文档是否全部有 category 字段
 **问题**：域聚合依赖 `category` 字段分组，需确认现有文档是否都有值。
 **证据**：
 - 全部 6 个文档均有 `category` 字段：api(1)、domain(1)、infrastructure(3)、troubleshooting(1)
 **结论**：现有文档无需修补，category 覆盖率 100%。
 ---
 ## E3: 去重 key 设计
 **问题**：用什么字段唯一标识一个文档用于去重。
 **证据**：
 - `KnowledgeEntry.filePath` 在 L0 索引内唯一
 - L1 向量索引的 `_source` 字段也是 filePath
 - 上传时 `saveToLocal()` 生成 `knowledge_base/{category}/{fileName}` 路径
 **结论**：统一用 `filePath` 作去重 key，L0 和 L1 一致。
 ---
 ## E4: Planner prompt token 增量是否可接受
 **问题**：knowledge map YAML 注入 Planner prompt 会增加固定 token 开销。
 **证据**：
 - 当前 planner prompt 21 行
 - 注入 knowledge map 约增加 200-400 字符（6 个文档场景）
 - 相比 Planner 整体 prompt + 历史消息，增量占比 < 5%
 **结论**：可接受，不构成性能瓶颈。
 ---
 ## E5: EvaluationService.tool_call_count 影响
 **问题**：去重后 `tool_call_count` 降低，是否影响 `EvaluationService` 评分逻辑。
 **证据**：
 - `EvaluationService` 使用 `tool_call_count` 作为评分因子
 - 去重导致重复调用被过滤，`tool_call_count` 下降
 - 这是修复效果（消除了无意义的重复调用），不是回归
 **结论**：`EvaluationService` 评分规则无需改动。下降的 `tool_call_count` 反映了真实效率提升。
 ---
 ## P1: 手写 JSON 解析器脆弱性
 **问题**：`KnowledgeIndexService.extractJsonValue` / `extractJsonArray` 在遇到含逗号、引号的自然语言字段时会截断。
 **证据**：
 - `whenToRetrieve` 字段由 LLM 生成，内容为自然语言（含逗号、分号等标点）
 - 手写解析器以 `"` 和 `,` 作分隔符，自然语言中的标点会导致提前截断
 - Jackson `ObjectMapper.readValue(metadata, Frontmatter.class)` 是项目已有依赖
 **结论**：全量替换为 Jackson，影响范围仅 `KnowledgeIndexService.parseDocumentToEntry()`，行为更健壮。
 ---
 ## P2: LookupResult 去重提示字段
 **问题**：去重命中时如何向 LLM 返回"不要重试"的信号。
 **证据**：
 - 复用 `primary.content` 语义不清，LLM 可能理解为正常检索结果
 - 独立 `message` 字段 + `found=false` 语义明确，LLM 能理解"已检索过"不再重试
 **结论**：`LookupResult` 新增 `String message` 字段，去重时填入提示文本。

 ## 未验证
 | 场景 | 原因 | 风险 | 补验建议 |
 |------|------|------|---------|
 | PRECISE 等级（L0 唯一精确匹配） | 测试会话无精确匹配场景 | 低 — L0 matchCount=1 的判断逻辑与 HIGHLY_RELEVANT 共用，实现确定性强 | 构造一条 L0 精确匹配的知识库文档后测试 |
 | domain_retrieved 域级去重 | 需要同一域全部文档已检索再查该域才触发 | 低 — isDomainRetrieved 逻辑简单，与 isDocRetrieved 等价 | Phase 2 启用域级硬限流时测试 |
 | DEDUPED 等级 | 当前 code path 去重时仍写 REFERENCE，DEDUPED 未被使用 | 低 — 设计预留，当前未启用 | Phase 2 若启用 DEDUPED 等级时验证 |
 | Phase 2 域级硬限流 | 非本次范围 | 中 — 当前仅有软约束（prompt），LLM 仍可能在 REFERENCE 下继续检索 | 实测观察，如果 lookup 调用仍偏高，启动 Phase 2 |
 ## 剩余风险
 1. **Prompt 软约束局限性**：实测 10 次调用中 9 次为 REFERENCE，说明 LLM 仍倾向于继续检索。如果 prompt 约束效果不足，需启用 Phase 2 域级硬限流。
 2. **L1 Metadata 解析兼容性**：L1 domain 兜底路径解析 metadata JSON，如果知识库文档 frontmatter 格式不一致可能解析失败，已有 try-catch 兜底。

 # Brief: executor-action-memory-relevance
 ## 背景
 ISS-002：Executor 在单次会话中调用 `lookup_knowledge` 20+ 次，大部分是同域换变体的冗余调用。前序 change `session-dedup-knowledge-map` 解决了文档级重复召回（ISS-001），但未解决 Executor 重复调用问题。
 ## 目标
 - Executor 获得行动记忆（知道自己本次会话已检索了哪些域）
 - 检索结果提供归一化质量等级（PRECISE/HIGHLY_RELEVANT/REFERENCE）+ 兜底信号
 - Executor prompt 提供明确的检索约束和"放弃检索"的合法出口
 - 原始分数入库保留可观测性，但不暴露给 LLM
 ## 范围
 - `RetrievedDocTracker`：域级 + 文档级双层记录
 - `LookupKnowledgeTool`：归一化层 + 行动记忆注入
 - `LookupResult`：新增 relevanceLevel / completenessHint / retrievedDomainsThisSession
 - `chat-executor-prompt.md`：检索约束重写
 - `ToolInvocation` + V010：入库可观测性
 ## 非目标
 - 不给 Executor 注入 knowledge map（保持 Agent 边界）
 - 不修改 Planner prompt 或 Planner 逻辑
 - 不修改 PrimaryResult / SupplementResult 的字段（不暴露原始分数）
 - Phase 2 域级硬限制暂不实施

 # Decisions: executor-action-memory-relevance
 ## 过程日志
 ### Clarify 阶段
 **入口摘要**：ISS-002 Executor 无约束重复调用 lookup_knowledge（单会话 20+ 次），需要行动记忆 + 归一化质量等级 + prompt 约束来解决。
 **slug**: `executor-action-memory-relevance`
 **规模分档**: `standard`（涉及 7 个文件，跨 DTO/工具层/持久化/Prompt，有设计决策需澄清）
 ### Context 阶段
 **devflow/index.md 使用状态**: 已命中。前序 change `session-dedup-knowledge-map`（archived）提供了 RetrievedDocTracker、KnowledgeDomainService、ISS-002 文档。
 **相关 ADR**: 无直接 ADR，但 `session-dedup-knowledge-map` 的 decisions.md 和 evidence.md 记录了文档级去重和 knowledge map 注入的决策。
 **不能违反的历史决策**:
 1. RetrievedDocTracker 的文档级去重必须保留
 2. knowledge map 只注入 Planner，不注入 Executor（本次讨论确认）
 3. L0/L1 原始分数不暴露给 LLM，只在归一化层内部使用（本次讨论确认）
 **需进入 OpenSpec 的上下文点**:
 1. L1 score 是 L2 距离（值域 [0,+∞)），不是归一化分数——阈值设计需基于实际分布
 2. L0 的 category 可从 KnowledgeEntry.getCategory() 直接获取；L1 需解析 metadata JSON
 3. ReactAgent 是自主决策工具调用的 Agent，Prompt 约束是软约束
 ### Grill 阶段 — Question Pool
 **维度：术语**
 1. [evidence-driven] `relevanceLevel` 三个等级（PRECISE/HIGHLY_RELEVANT/REFERENCE）的边界是否清晰，是否存在 LLM 误解的可能？ → **已查证**：三个等级语义明确，PRECISE=唯一匹配、HIGHLY_RELEVANT=高分命中、REFERENCE=低置信度参考。LLM 理解风险低。
 **维度：边界**
 2. [evidence-driven] L1 score 是 L2 距离（值域 [0,+∞)），当前代码无阈值判断。归一化阈值如何设计？ → **已查证**：L2 距离典型范围取决于 BGE-M3 1024 维 embedding 的尺度，需从 `tool_invocation.retrieval_details` 中查询实际 `l1_scores` 分布才能定阈值。当前先以常量定义，标记为"需实测校准"。
 3. [evidence-driven] L1 结果的 category 提取需要解析 metadata JSON 字符串，当前 `SearchResult.metadata` 是 `toString()` 的结果。归一化层是否需要 L1 的 domain？ → **已查证**：L1 的 domain 主要用于 RetrievedDocTracker 的域级记录。如果 L0 已命中且包含 category，可直接用 L0 的 category；如果仅 L1 命中，需解析 metadata 提取 category。当前知识库中 L0 大概率先命中，L1 domain 提取作为兜底路径。
 4. [user-interview] 归一化阈值（L1 score 分界线）在实测数据不足时，是否接受先用保守初始值 + 后续调优的策略？ → **用户待确认**
 **维度：验收**
 5. [evidence-driven] 现有 `tool_invocation` 表 `retrieval_details` JSON 中 `l1_scores` 存的是 L2 距离原始值，新增的 `relevance_level` 和 `completeness_hint` 入库后是否需要回填历史数据？ → **已查证**：不需要回填历史数据，新列 nullable 即可，历史记录 relevance_level=null。
 ### Grill 结论
 **evidence-driven 汇报**：
 - E1: relevanceLevel 三等级语义清晰，LLM 误解风险低
 - E2: L1 score 是 L2 距离，值域不固定，阈值需实测校准
 - E3: L0 category 直接可用，L1 category 需解析 metadata（兜底路径）
 - E4: 历史数据不回填，新列 nullable
 **user-interview 已确认**：
 - Q4: 归一化阈值先用保守初始值 + 后续调优 → **用户已确认**，并建议用 Min-Max 归一化到 [0,1]
 ### Specify 阶段补充
 **BGE-M3 L2 归一化实测验证**：
 - FullPipelineSmokeTest.embeddingBgeM3Works() 新增 L2 范数断言
 - 结果：范数=1.00000002，误差 < 0.01，测试通过
 - 结论：BGE-M3 输出为 L2 归一化单位向量，L2 距离数学硬上界 = 2.0
 - Min-Max 归一化公式：`similarity = 1 - min(l2Score, 2.0) / 2.0`
 **Cross-artifact 对齐检查**：
 | 对齐项 | 状态 |
 |--------|------|
 | brief 目标/范围/非目标 → proposal 覆盖 | 已对齐 |
 | proposal 范围/约束 → design 覆盖 | 已对齐 |
 | design 归一化/行动记忆/接口影响 → specs 覆盖 | 已对齐 |
 | specs 可观察行为 → tasks 覆盖 | 已对齐 |
 **接口影响分级**：
 - RetrievedDocTracker 数据结构升级 → L2（内部接口，消费者只有 LookupKnowledgeTool）
 - LookupResult 新增 3 字段 → L2（工具返回值，无跨模块调用方）
 - tool_invocation 新增 2 列 → L2（Flyway nullable，不影响现有查询）
 - chat-executor-prompt.md 更新 → L1（Prompt 文本变更）
 ### Audit 阶段
 **架构风险评估**（5 句以内）：
 1. 归一化层嵌入 LookupKnowledgeTool 内部（静态方法），无跨模块耦合风险。
 2. RetrievedDocTracker 升级为双层结构，数据量级不变（文档数 × session 数），内存无风险。
 3. L1 metadata 解析 category 是兜底路径，如果 JSON 格式不一致可能解析失败——已有 try-catch 兜底。
 4. 归一化阈值 yml 配置化，运行时调优不需要改代码和重启——运维友好。
 5. Prompt 约束仍依赖 LLM 遵守——如果 Phase 1 效果不足，Phase 2 域级硬限制的 isDomainRetrieved 已就绪，无需额外改造。

 ## Static Verification

 ## Script Verification

 - [x] Runtime session `9138f064` wrote `tool_trace_summary[*].source_invocation_ids`.
 - [x] LOW_CONFID final answer included disclaimer and verifier-derived evidence gaps.
 ## Unverified
 | Scenario | Reason | Risk | Follow-up |
 | --- | --- | --- | --- |
 | PASS runtime path | The exercised complex runtime case produced LOW_CONFID. | Low; PASS routing is simple pass-through after parsed verifier decision. | Add a fixture or deterministic verifier test if this becomes product-critical. |
 | REJECT runtime path | No forced contradiction case was run after traceability changes. | Medium; REJECT is the safety-critical degraded path. | Add a targeted test with a fabricated claim and evidence contradiction. |
 | Document-path-level evidence mapping | Current implementation records invocation ids and source document labels, not guaranteed canonical document paths for every retrieval mode. | Low for current audit need; medium for future UI drill-down. | Extend retrieval details with canonical document paths in a later change. |
 ## Remaining Risks
 1. Verifier output still depends on model compliance with JSON schema; code falls back to LOW_CONFID on missing or invalid output.
 2. `AgentLoggingHook` is shared by several agent paths; current changes preserve compile and runtime behavior but should be watched in AiOps flows.
 3. `SupervisorAgent` construction remains as legacy residue in `ChatService`; runtime orchestration is explicit, but a later cleanup should remove unused supervisor construction.

 # Brief: chat-verifier-agent
 ## Background
 The complex Chat path previously returned Executor answers without a synchronous quality gate. Existing rule scoring was asynchronous and post-hoc, so it could not prevent unsupported answers from reaching users.
 ## Goals
 1. Add a Verifier Agent after Executor in the complex chat path.
 2. Require structured verifier output with `PASS`, `LOW_CONFID`, or `REJECT`.
 3. Route final user output in code based on verifier verdict.
 4. Persist verifier results under `diagnosis_session.self_evaluation.verifier_evaluation`.
 5. Preserve rule scoring under `rule_evaluation`.
 6. Make verifier decisions traceable to real tool invocations through `evidence_refs` and `source_invocation_ids`.
 ## Scope
 - `ChatService`: explicit `planner -> executor -> verifier` orchestration, max two rounds, verdict routing, retry context, verifier persistence.
 - `VerifierInputHook`: explicit verifier input payload.
 - `ToolTraceSummaryService`: evidence summary from persisted tool calls.
 - `VerifierContextHolder`: round-local verifier context.
 - `SelfEvaluationMergeService`: safe JSON merge for evaluation channels.
 - `AgentLoggingHook`: concise verifier thought and fuller structured output retention.
 - `chat-verifier-prompt.md`: verifier contract, verdict matrix, and traceability schema.
 ## Non-Goals
 - Verifier does not call tools.
 - Verifier does not rewrite Executor output.
 - Single-agent chat path remains outside this change.
 - No database schema migration is included.
 - Document-path-level evidence attribution is deferred; current traceability is invocation-level with source document labels.

 **入口摘要**: 在 Chat 多 Agent 链路中新增 Verifier Agent，作为 Executor 输出后的质量门禁，做事实核查。
 **slug**: `chat-verifier-agent`
 **规模分档**: standard
 ### Context 阶段
 **devflow/index.md 使用状态**: 已命中。前序 change `executor-action-memory-relevance`（archived）提供了 Chat 多 Agent 当前链路（Supervisor → Planner → Executor）。
 **不能违反的历史决策**:
 1. Executor 已有完整的行动记忆和归一化质量等级，Verifier 不需要重复验证检索质量
 2. Chat Supervisor 的职责是调度，Verifier 作为子 Agent 加入后不改变 Supervisor 的定位
 3. 已有 evidence_score 做事后评分，Verifier 是事前门禁，两者不冲突
 **需进入 OpenSpec 的上下文点**:
 1. Verifier 不需要工具调用，只是一个质量核查 Agent
 2. Verifier 需要访问 Executor 的输出 + 工具调用记录
 3. Supervisor prompt 需要重写以包含 Verifier 调度规则
 4. groundedness_score 的阈值需要在代码中定义

                                 写入 self_evaluation JSON
 ```
 **架构风险评估**（5 句以内）：
 1. Verifier 是轻量 Agent（无工具、无外部依赖），架构风险低。
 2. MessagesModelHook 纯过滤逻辑，不引入新数据源。
 3. LOW_CONFID 分级处理 + 回调仅一次的设计，避免无限循环风险。
 4. REJECT 降级确保编造内容不到达用户。
 5. 审计结论不影响现有 design/tasks，无需回写。
 ### 关键取舍
 - 决策：LOW_CONFID < 0.5 回调 Planner 一次
  - 原因：给系统一次修正机会，但避免无限循环
  - 影响：Supervisor prompt 需维护"已回调"状态
  - 风险接受：用户已确认
 - 决策：Verifier 判决写入 diagnosis_session.self_evaluation JSON
  - 原因：不改表结构，与 evidence_score 统一可观测体系
  - 影响：ChatService 后处理需追加 JSON
  - 风险接受：用户已确认
 ### Archive-Ready Update
 - 实现调整：最终运行链路由 `ChatService` 显式调用 `planner -> executor -> verifier`，不再依赖 Supervisor prompt 保证 verifier 被调用。
 - 可追溯性补充：`tool_trace_summary` 增加 `trace_ref`、`source_invocation_ids`、查询样本、检索层级、相关性等级和来源文档标签。
 - 可追溯性补充：`facts_checked[*].evidence_refs` 被 prompt 要求、代码解析并持久化。
 - 验证记录：`mvn -q -DskipTests compile` 通过。
 - 验证记录：运行会话 `9138f064` 走通 planner、executor、verifier，并持久化 `verifier_evaluation.facts_checked[*].evidence_refs` 与 `tool_trace_summary[*].source_invocation_ids`。
 - 当前状态：OpenSpec change 已归档到 `openspec/changes/archive/2026-07-03-chat-verifier-agent/`，主规格已同步到 `openspec/specs/chat-verifier-agent/spec.md`。

 # Evidence: chat-verifier-agent
 ## Code Evidence
 ### Complex chat path now invokes verifier deterministically
 - File: `src/main/java/com/superbiz/agent/service/ChatService.java`
 - Evidence: `executeChatComplex` calls planner, executor, then verifier directly through `callAgent(...)`.
 - Conclusion: runtime no longer depends on prompt-only Supervisor behavior to call verifier.
 ### Verifier receives explicit inputs
 - File: `src/main/java/com/superbiz/agent/hook/VerifierInputHook.java`
 - Evidence: the hook builds a JSON payload with `original_query`, `executor_final_answer`, `tool_trace_summary`, and `retry_context`.
 - Conclusion: verifier input is stable and does not depend on guessing the last assistant message from raw history.
 ### Tool evidence is traceable to persisted invocations
 - File: `src/main/java/com/superbiz/agent/service/ToolTraceSummaryService.java`
 - Evidence: summaries include `trace_ref`, `source_invocation_ids`, `query_samples`, `retrieval_layers`, `relevance_levels`, and `source_documents`.
 - Conclusion: verifier facts can be correlated with actual `tool_invocation` rows.
 ### Verifier facts preserve evidence references
 - File: `src/main/java/com/superbiz/agent/service/ChatService.java`
 - Evidence: verifier parsing preserves `facts_checked[*].evidence_refs` and persists `tool_trace_summary` under `verifier_evaluation`.
 - Conclusion: `self_evaluation` now contains both verifier judgments and the evidence index used to form them.
 ### Evaluation channels no longer overwrite each other
 - File: `src/main/java/com/superbiz/agent/service/SelfEvaluationMergeService.java`
 - Evidence: rule and verifier evaluations are merged into separate keys.
 - Conclusion: asynchronous rule scoring preserves verifier output.
 ### Verifier logging is less noisy
 - File: `src/main/java/com/superbiz/agent/hook/AgentLoggingHook.java`
 - Evidence: verifier `thought` stores a concise verdict summary, while fuller model output remains available in structured storage.
 - Conclusion: `agent_step.thought` is no longer a misleading place for full verifier JSON.
 ## Runtime Evidence
 - Compile verification passed: `mvn -q -DskipTests compile`.
 - Runtime session `9138f064` executed `planner -> executor -> verifier`.
 - Runtime session `9138f064` persisted `verifier_evaluation.facts_checked[*].evidence_refs`.
 - Runtime session `9138f064` persisted `verifier_evaluation.tool_trace_summary[*].source_invocation_ids`.
 ## Design Evidence
 - `LOW_CONFID` returns a fixed disclaimer and verifier-derived gaps.
 - `REJECT` returns degraded output and does not pass through the raw Executor answer.
 - `retry_context` is derived from verifier-identified missing evidence facts.

 # MVP Demo Trace Acceptance
 ## Result
 Accepted for implementation scope.
 ## Verification
 ### Static Verification
 - Command: `mvn -q -DskipTests compile`
 - Result: passed
 - Notes: New trace controller, service, DTO, profile, verifier fallback, and test sources compile with the project.
 ### Script Verification
 - Command: `mvn -q "-Dtest=DiagnosisTraceServiceTest,ChatServiceSupervisorAgentTest" test`
 - Result: passed
 - Notes: Covers successful trace aggregation, missing-session 404 path via `SessionNotFoundException`, low-confidence no-retry behavior, method-tool injection, and verifier fallback when Supervisor skips `chat_verifier`.
 ### OpenSpec Verification
 - Command: `openspec validate mvp-demo-trace-acceptance --strict`
 - Result: passed
 ### GitNexus Verification
 - Result: skipped by user decision
 - Notes: User requested subsequent project flow to bypass GitNexus.
 ### Manual / Runtime Verification
 - Steps: Follow `mvp/demo/README.md` with `--spring.profiles.active=mvp-demo`.
 - Result: passed
 - Notes:
  - Session `mvp-demo-payment-timeout-20260703-rerun2` completed as `SUCCESS`.
  - Chat request returned `code=200`, `success=true`, and the same `sessionId`.
  - Chat duration was `96316 ms`; persisted session duration was `95028 ms`.
  - Trace API returned `code=200`, `returnedSteps=13`, `returnedTools=12`, `hasVerifier=true`, and `verifierVerdict=LOW_CONFID`.
  - Trace agents included `planner,executor,verifier`.
  - Trace tools included `lookup_knowledge,query_logs,query_metrics`.
  - Feedback submission returned success, and a follow-up trace query showed `feedback=useful`.
  - MySQL verification confirmed `agent_step` count `13` with agents `executor,planner,verifier`.
  - MySQL verification confirmed `tool_invocation` count `12` with tools `lookup_knowledge,query_logs,query_metrics`.
 ## Completed Scope
 - Added `GET /api/diagnosis/{sessionId}/trace`.
 - Added read-only trace aggregation from persisted diagnosis tables.
 - Added `mvp-demo` profile overlay.
 - Added payment-timeout demo acceptance documentation.
 - Added MVP note for interview storytelling.
 - Added verifier fallback so runtime trace remains complete when Supervisor returns without `verifier_output`.
 ## Known Limits
 - `mvp-demo` is not a fully offline mock runtime.
 - Runtime still depends on available MySQL, Redis, Milvus/Zilliz, model, and embedding configuration.
 - Sensitive configuration cleanup remains intentionally deferred.
 - Supervisor can still make inefficient routing choices inside a single round; `ChatService` now invokes `chat_verifier` as a fallback when Supervisor returns without `verifier_output`, so trace completeness is preserved for the MVP demo.
 ## Handoff
 - Runtime demo passed with current infrastructure.
 - OpenSpec archive confirmation: requested by user after successful rerun.

 # MVP Demo Trace Acceptance Brief
 ## Background
 - User goal: make the MVP runnable, observable, and explainable for an Agent Engineer interview.
 - Current problem: the system can execute diagnosis, but reviewers need a simple way to replay one session from final answer back to agent steps and tool evidence.
 - Associated OpenSpec: `openspec/changes/mvp-demo-trace-acceptance/`
 - Devflow scale: standard-light.
 ## Scope
 - In scope:
  - `mvp-demo` Spring profile overlay.
  - `GET /api/diagnosis/{sessionId}/trace` read-only API.
  - Trace aggregation DTO/service/controller.
  - Focused service tests.
  - Demo and acceptance documentation.
 - Out of scope:
  - Sensitive configuration cleanup.
  - Full offline LLM/vector/database mock runtime.
  - Database schema migration.
  - Changes to chat execution, verifier routing, upload, or feedback behavior.
 - Impact area:
  - `src/main/java/com/superbiz/agent/controller`
  - `src/main/java/com/superbiz/agent/service`
  - `src/main/java/com/superbiz/agent/dto`
  - `src/main/resources/application-mvp-demo.yml`

 # MVP Demo Trace Acceptance Decisions
 ## Clarify
 - Entry summary: continue the MVP toward a runnable and explainable demo by adding an `mvp-demo` profile, an end-to-end acceptance case, and a trace query API.
 - Slug: `mvp-demo-trace-acceptance`
 - Devflow scale: standard-light. The change adds a public read-only API and documentation, but does not alter core chat execution or persistence schemas.
 ## Context
 - `devflow/index.md` was checked. Relevant history includes `session-storage`, `confidence-feedback`, `executor-action-memory-relevance`, and `chat-verifier-agent`.
 - `mvp/archive/2026-07-09-doc-cleanup/notes/agent-engineering-decisions.md` already recommends the next phase as "可复现 MVP Demo", including `mvp-demo` profile, fixed diagnosis case, one-click request, and `GET /api/diagnosis/{sessionId}/trace`.
 - `mvp/issues/archived/ISS-003-mvp-design-implementation-review.md` identifies test stability, session traceability, verifier evidence chain, upload path, and SupervisorAgent consistency as historical MVP concerns. Security cleanup was intentionally deferred by user decision at that time.
 ## Question Pool
 | # | Dimension | Question | Mode | Status |
 |---|---|---|---|---|
 | Q1 | Terminology | Should "trace" mean persisted diagnosis execution evidence instead of transient frontend chat history? | evidence-driven | Resolved |
 | Q2 | Boundary | Should this change modify chat execution or only expose existing persisted evidence? | evidence-driven | Resolved |
 | Q3 | Acceptance | What proves the MVP flow is end-to-end enough for demo/interview use? | evidence-driven | Resolved |
 | Q4 | Interface | What is the API impact level for `GET /api/diagnosis/{sessionId}/trace`? | evidence-driven | Resolved |
 ## Evidence-driven
 | Conclusion | Evidence Source | Reported To User |
 |---|---|---|
 | Trace should aggregate persisted diagnosis evidence, not Redis-only chat history. | `DiagnosisSession`, `AgentStep`, `ToolInvocation` entities and repositories | Reported in progress update |
 | Core chat execution does not need to change for this slice. | Existing unified chat path and SupervisorAgent commits; requested scope is demo/profile/trace/acceptance | Reported in progress update |
 | End-to-end acceptance should cover start -> chat -> trace -> feedback. | `ChatController`, `FeedbackController`, traceable session id decision in MVP notes | Reported in progress update |
 | Trace API is additive L3 because it is a new HTTP API for frontend/demo consumers. | sm-flow interface impact rules | Recorded in OpenSpec design |
 ## User-interview
 | Question | User Words | Confirmation | OpenSpec Writeback |
 |---|---|---|---|
 | Should security/sensitive config cleanup be included? | "安全问题先不考虑"; "敏感配置先不做" | Confirmed | Non-goal |
 | Should this be implemented under sm-flow? | "按照 sm-flow 的流程来实现吧" | Confirmed | This change follows sm-flow artifacts |
 ## Key Decisions
 - Decision: Add a new trace API instead of embedding trace details in `/api/chat`.
  - Reason: Chat execution and observability should stay decoupled.
  - Impact: Demo can query trace after any successful chat request using the same session id.
  - Risk accepted: Response shape is new and should be treated as demo-facing contract.
 - Decision: Keep `mvp-demo` profile as configuration overlay, not a fully mocked standalone runtime.
  - Reason: The current MVP still depends on real DB/Redis/Milvus/LLM for full chat execution; this change avoids inventing a fake runtime that hides integration behavior.
  - Impact: Demo profile improves repeatability for logs/metrics, while docs remain explicit about required external services.
  - Risk accepted: End-to-end acceptance may still require valid infrastructure and keys.
 ## Cross-Artifact Alignment
 | Upstream -> Downstream | Check | Status |
 |---|---|---|
 | brief/prd -> proposal | Goal, scope, non-goals, and acceptance expectation are in proposal | Aligned |
 | proposal -> design | Scope, constraints, and API impact are in design | Aligned |
 | design -> specs/tasks | Trace DTO, controller/service, demo profile, and docs are represented | Aligned |
 | specs -> tasks | Observable behavior is covered by executable tasks | Aligned |
 ## Architecture Audit
 - Data path: HTTP trace request -> controller -> trace service -> repositories -> aggregate DTO -> `Result.success`.
 - The service is read-only and does not mutate diagnosis, step, tool, or feedback state.
 - No schema change is needed because all required fields already exist in `diagnosis_session`, `agent_step`, and `tool_invocation`.
 - Main risk is response size for large sessions; MVP mitigates by returning previews already persisted by tools rather than raw external logs.
 - The additive API is acceptable for MVP because old callers remain unaffected.
 ## Pre-apply Research
 - Reference implementations read:
  - `ChatController` for `/api` controller conventions.
  - `FeedbackController` for simple API controller shape.
  - `GlobalExceptionHandler` and `SessionNotFoundException` for 404 handling.
  - `DiagnosisSessionRepository`, `AgentStepRepository`, `ToolInvocationRepository` for available queries.
  - `DiagnosisSession`, `AgentStep`, `ToolInvocation` for fields.
 - Impact analysis:
  - `DiagnosisSessionRepository`: LOW, direct imports in service/controller paths.
  - `AgentStepRepository`: HIGH because it participates in chat/AiOps flows. This change only consumes existing query methods and does not modify the repository.
  - `ToolInvocationRepository`: LOW.
 ## Commit Gate
 - OpenSpec proposal/design/specs/tasks exist.
 - API impact: L3 additive collaboration API, documented in design and spec.
 - User-confirmed non-goal: sensitive configuration cleanup remains out of scope.
 - No unresolved user-interview questions remain for this slice.

 # MVP Demo Trace Acceptance Evidence
 ## Evidence
 | Source | Evidence | Conclusion | Reported |
 |---|---|---|---|
 | `DiagnosisSessionRepository` | Existing `findBySessionId(String)` query | Trace can locate the session without new repository methods | Yes |
 | `AgentStepRepository` | Existing `findBySessionIdOrderByStepIndex(String)` query | Agent steps can be returned in execution order | Yes |
 | `ToolInvocationRepository` | Existing `findBySessionIdOrderByIdAsc(String)` query | Tool evidence can be returned in persisted order | Yes |
 | `GlobalExceptionHandler` | Handles `SessionNotFoundException` as HTTP 404 with `Result.error(404, ...)` | Missing trace can reuse existing error contract | Yes |
 | `mvn -q "-Dtest=DiagnosisTraceServiceTest" test` | Command passed | Trace aggregation behavior is covered offline | Yes |
 | `mvn -q -DskipTests compile` | Command passed | New code compiles with the full project | Yes |
 | `gitnexus detect-changes --repo SuperBizAgent-java` | Command completed with `No changes detected` and line-ending warnings | Required GitNexus check ran; output likely does not capture newly added files | Yes |
 ## Evidence-driven Conclusions
 - Conclusion: No database migration is required.
  - Evidence: All trace fields are available from existing `diagnosis_session`, `agent_step`, and `tool_invocation` entities.
  - Risk: Response shape becomes a new API contract.
  - User confirmation: Not required; additive L3 API recorded in OpenSpec.
 - Conclusion: Trace aggregation can be tested without external infrastructure.
  - Evidence: `DiagnosisTraceServiceTest` uses mocked repositories and an `ObjectMapper`.
  - Risk: Runtime integration still depends on configured infrastructure.
  - User confirmation: Not required; limitation recorded in acceptance docs.

 # Brief: aiops-alert-scope-control
 ## Background
 After `aiops-traceable-diagnosis-entry`, AIOps can be triggered by payload and replayed through trace. Runtime verification showed one semantic gap: payload mode still produced a broad report over all active mock alerts.
 ## Goal
 Make AIOps scope explicit:
 - Payload present -> targeted diagnosis for the supplied alert.
 - Payload absent -> automatic active-alert discovery and diagnosis.
 ## Scope
 - In scope:
  - `AiOpsService.buildTaskPrompt(...)` scope rules.
  - Focused tests.
  - Demo acceptance wording.
 - Out of scope:
  - Verifier integration.
  - Java-side filtering of tool results.
  - API shape changes.
  - Database changes.

 # Decisions: aiops-alert-scope-control
 ## Clarify
 - Entry summary: tighten AIOps report scope after runtime verification showed payload mode still analyzes all active alerts.
 - Slug: `aiops-alert-scope-control`
 - Scale: standard-light.
 ## Context
 - AIOps traceability is implemented and verified.
 - Mock Prometheus returns multiple active alerts.
 - Payload demo supplies `HighCPUUsage/payment-service`, but previous report expanded to `HighMemoryUsage` and `SlowResponse`.
 ## Grill Question Pool
 | # | Dimension | Question | Mode | Status |
 |---|---|---|---|---|
 | Q1 | Product Boundary | What makes `/api/ai_ops` different from `/api/chat` when payload exists? | evidence-driven | Payload is alert-event driven and should be scoped to that event. |
 | Q2 | Scope | Should payload mode ignore all other active alerts? | user-interview | No; mention only as related risk/context. |
 | Q3 | Compatibility | Should no-payload mode keep old "query active alerts" behavior? | evidence-driven | Yes. |
 | Q4 | Enforcement | Should Java filter unrelated tool results now? | evidence-driven | No; prompt-only is sufficient for this small change. |
 | Q5 | Verifier | Should this change add AIOps Verifier? | user-interview | No; keep deferred. |
 ## Evidence-Driven Conclusions
 | Conclusion | Evidence Source | Result |
 |---|---|---|
 | Scope issue is prompt-level. | `/api_ ai_ops` trace showed all mock alerts analyzed despite payload. | Update task prompt. |
 | No API or persistence changes are needed. | `AIOpsRequest` already carries payload and trace works. | Keep endpoint unchanged. |
 | Blast radius is low. | `buildTaskPrompt(...)` is internal to `AiOpsService`. | Add tests for prompt content. |
 ## GitNexus
 GitNexus remains skipped by prior user decision and because tools are not exposed in this session. Local impact analysis is recorded instead.
 ## Key Decisions
 - Payload mode is detected when any alert field is present.
 - Payload mode final report must focus on the supplied alert.
 - No-payload mode must first call `queryPrometheusAlerts`.
 - Other active alerts in payload mode can appear only as related risk, not as separate root-cause sections.

 # Evidence: aiops-alert-scope-control
 ## Local Impact Analysis
 - `AiOpsService.buildTaskPrompt(...)` is used by `executeAiOpsAnalysis(...)`.
 - No controller, DTO, repository, or database changes are required.
 - Existing `AiOpsServiceTest` already exercises request summary helpers and can be extended for scope prompt rules.
 ## Verification Results
 - `mvn -q "-Dtest=AiOpsServiceTest" test` passed.
 - `mvn -q -DskipTests compile` passed.
 - `openspec.cmd validate aiops-alert-scope-control --strict` passed.
 ## Runtime Verification
 - Runtime session: `mvp-demo-aiops-payment-cpu-codex-scope-003`.
 - `/api/ai_ops` SSE emitted the requested `session` message and finished with `done`.
 - `diagnosis_session` persisted:
  - `agent_flow = AI_OPS`
  - `status = SUCCESS`
  - `total_duration_ms = 69875`
  - `step_count = 5`
  - `tool_call_count = 8`
 - Tool invocation counts:
  - `query_metrics = 1`
  - `lookup_knowledge = 1`
  - `query_logs = 6`
 - Report scope check:
  - `告警根因分析 - HighCPUUsage` exists.
  - `告警根因分析 - HighMemoryUsage` does not exist.
  - `告警根因分析 - SlowResponse` does not exist.

 # Brief: aiops-traceable-diagnosis-entry
 ## Background
 The MVP chat diagnosis path is now traceable through `diagnosis_session`, `agent_step`, `tool_invocation`, and `GET /api/diagnosis/{sessionId}/trace`. The older `/api/ai_ops` endpoint still acts like a standalone SSE demo: it accepts no alert payload, generates an internal session id, and does not make trace replay obvious to callers.
 ## Goal
 Turn AIOps into an alert-triggered diagnosis entry point that shares the same evidence and trace story as the main MVP, without rewriting the whole AIOps flow.
 ## Scope
 - In scope:
  - Optional AIOps alert request body.
  - Stable request/session id propagation.
  - Persisted AIOps query summary and final answer.
  - SSE session id event.
  - Demo documentation and focused tests.
 - Out of scope:
  - Full AIOps and ChatService unification.
  - AIOps Verifier integration.
  - Database schema changes.
  - Sensitive configuration cleanup.
  - Fully offline runtime.
