# 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.
## Optional: HTML Card
**Only when the user explicitly requests it.**
Generate an HTML visualization card as a shareable deliverable.

### Output Format

### HTML Card Generated
- **Path:** `outputs/{project}-essence.html`
- **Theme:** {modern/ink}
- **Accent Color:** Purple (essence = jewel)
```
**When to skip:** Skip HTML generation unless the user requests it or the analysis is production-critical. When HTML generation fails, deliver a plain-text report instead.
---
## 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.
## Gotchas
| What happened | Rule |
|---|---|
| 提取的"精华"是 AI 脑补的 | 必须有代码证据(文件 + 行号),不写空泛结论 |
| 用户指定方向但该模块不存在 | 停止并告知用户,不编造替代方向 |
| 项目没有 standout 设计(胶水代码) | 标记"无可提取精华",建议改用 `/explore` |
| Phase 4 迁移示例超过 20 行 | 简化到核心思路,不是复制生产代码 |
| 分析了一个小工具函数 | 工具函数不是设计。设计影响整个架构,工具只解决一个问题 |
| 从 commit message 推断作者意图但没有代码佐证 | Commit message 是辅助证据,必须有代码结构本身的支持 |
| 透镜模式选错导致输出不符预期 | Phase 1 先确认透镜,Mechanical 读代码、Intentional 读文档、Evolution 读历史 |
| 透镜分析流于表面 | 每个透镜有特定输出格式:Mechanical→图 + 接口,Intentional→决策记录,Evolution→时间线 |
| HTML 卡片生成失败 | 降级到纯文本报告,不阻塞分析交付 |

# 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.

# 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

# Exploring Codebases with GitNexus
## When to Use
- "How does authentication work?"
- "What's the project structure?"
- "Show me the main components"
- "Where is the database logic?"
- Understanding code you haven't seen before

# 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

```
## 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

description: Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.

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>)
Working on task 3/7: <task description>
[...implementation happening...]
✓ Task complete
Working on task 4/7: <task description>
[...implementation happening...]
✓ Task complete
```
**Output On Completion**
```
## Implementation Complete
**Change:** <change-name>
**Schema:** <schema-name>
**Progress:** 7/7 tasks complete ✓
### Completed This Session
- [x] Task 1
- [x] Task 2
...
All tasks complete! Ready to archive this change.
```
**Output On Pause (Issue Encountered)**
```
## Implementation Paused
**Change:** <change-name>
**Schema:** <schema-name>
**Progress:** 4/7 tasks complete
### Issue Encountered
<description of the issue>
**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

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

name: openspec-explore
description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
license: MIT
compatibility: Requires openspec CLI.
metadata:
author: openspec
version: "1.0"
generatedBy: "1.3.1"
---
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)
---
## Handling Different Entry Points
**User brings a vague idea:**
```
User: I'm thinking about adding real-time collaboration
You: Real-time collab is a big space. Let me think about this...

Or add a spike task to investigate?
```
**User wants to compare options:**
```
User: Should we use Postgres or SQLite?
You: Generic answer is boring. What's the context?
User: A CLI tool that tracks local dev environments
You: That changes everything.

Offline yes ✓ no ✗
Single file yes ✓ no ✗
SQLite. Not even close.
Unless... is there a sync component?
```
---
## 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
