## 当前架构一句话
|
||||
|
||||
SuperBizAgent MVP 是一个面向故障诊断的可追踪 Agent 系统:Chat 和 AIOps 入口统一进入 Agent 编排,Executor 通过显式工具收集日志、指标和知识库证据,Chat 链路由 Gatekeeper 做引用真实性校验、Verifier 做可推导性判断、Composer 生成最终表达;多轮会话元数据落到 `chat_session`,每次诊断运行落到 `diagnosis_run`,步骤和工具明细通过 `agent_step.run_id`、`tool_invocation.run_id` 关联,最终通过 Trace API 和评测脚本证明诊断链路可解释、可回放、可对比。

# Agent 编排架构
|
||||
# Diagnosis Agent 执行架构
|
||||
|
||||
**更新日期**:2026-07-08
|
||||
**更新日期**:2026-07-22
|
||||
**状态**:当前可运行架构
|
||||
**参考历史文档**:`archive/2026-07-05-legacy/agent-architecture.md`
|
||||
|
||||
## 1. 设计定位
|
||||
## 1. 单 Agent 原则
|
||||
|
||||
旧版 Agent 架构把系统描述为 Supervisor、Planner、SubAgent、Verifier 的团队协作。当前 MVP 保留这个核心思想,但实现更收敛:
|
||||
当前业务诊断只有一个 `Diagnosis Agent`。它使用框架 `ReactAgent` 完成规划、行动、观察和最终 Draft,但项目不在外层复制 ReAct 状态机,也不使用业务 Graph 或多角色协作链。
|
||||
|
||||
- Chat 链路使用固定顺序工作流:`Planner -> Executor -> Gatekeeper -> Verifier -> Composer`。
|
||||
- AIOps 链路使用 `SupervisorAgent` 调度 `Planner + Executor`,最终由规则评估器做轻量验证。
|
||||
- 当前没有拆分 ExternalApiSubAgent、InternalErrorSubAgent、DatabaseSubAgent;这些作为后续演进方向保留。
|
||||
- 证据工具不直接散落在各个 Agent 里,而是通过 Spring AI ToolCallback / `@Tool` 统一暴露。
|
||||
## 2. 职责
|
||||
|
||||
## 2. 当前 Agent 全景
|
||||
Diagnosis Agent:
|
||||
|
||||
```mermaid
|
||||
flowchart TB
|
||||
subgraph Chat["Chat diagnosis"]
|
||||
ChatIn["POST /api/chat"] --> ChatService["ChatService"]
|
||||
ChatService --> ChatPlanner["chat_planner"]
|
||||
ChatPlanner --> ChatExecutor["chat_executor"]
|
||||
ChatExecutor --> ChatTools["evidence tools"]
|
||||
ChatTools --> ChatExecutor
|
||||
ChatExecutor --> ChatGatekeeper["ExecutorGatekeeperService"]
|
||||
ChatGatekeeper --> ChatVerifier["chat_verifier"]
|
||||
ChatVerifier --> ChatDecision{"PASS / LOW_CONFID / REJECT"}
|
||||
ChatDecision --> ChatComposer["chat_composer"]
|
||||
ChatComposer --> ChatAnswer["final answer"]
|
||||
end
|
||||
- 接收当前 query 与可选、受限的安全 PreviousTurn。
|
||||
- 自主选择只读 evidence Tool。
|
||||
- 根据 Agent projection 判断是否需要继续查询。
|
||||
- 输出结构化 `DiagnosisDraft`,每条 analysis 绑定 framework `tool_call_id`。
|
||||
- 证据不足时明确限制,不补造事实。
|
||||
|
||||
subgraph AiOps["AIOps diagnosis"]
|
||||
AiOpsIn["POST /api/ai_ops"] --> AiOpsService["AiOpsService"]
|
||||
AiOpsService --> Supervisor["ai_ops_supervisor"]
|
||||

|
||||
AiOpsTools --> AiOpsReport["alert report"]
|
||||
AiOpsReport --> AiOpsRule["AiOpsRuleEvaluationService"]
|
||||
end
|
||||
Diagnosis Agent 不负责:

||||
subgraph Trace["Trace persistence"]
|
||||
ChatSession["chat_session"]
|
||||
Run["diagnosis_run"]
|
||||
Step["agent_step"]
|
||||
Invocation["tool_invocation"]
|
||||
SelfEval["self_evaluation"]
|
||||
end
|
||||
- HTTP/SSE、Session/Run 生命周期和持久化。
|
||||
- 模型/Tool/Token/timeout/cancel 预算。
|
||||
- Tool 参数授权、raw response 投影或证据物理验真。
|
||||
- SemanticGuard 与最终发布决定。
|
||||
|
||||
ChatService --> ChatSession
|
||||
ChatService --> Run
|
||||
ChatPlanner --> Step
|
||||
ChatExecutor --> Step
|
||||
ChatGatekeeper --> SelfEval
|
||||
ChatVerifier --> Step
|
||||
ChatTools --> Invocation
|
||||
ChatDecision --> SelfEval
|
||||
ChatComposer --> Step
|
||||
|
||||
AiOpsService --> ChatSession

|
||||

||||
AiOpsExecutor --> Step
|
||||

|
||||
AiOpsRule --> SelfEval
|
||||
```
|
||||
|
||||
## 3. Chat 编排
|
||||
|
||||
Chat 复杂诊断采用 `SequentialAgent`,顺序固定:
|
||||
|
||||
```text
|
||||
chat_planner
|
||||
-> chat_executor
|
||||
-> lookup_knowledge / query_logs / query_metrics / date_time
|
||||
-> outputs executor_evidence_v2
|
||||
-> VerifierInputHook / ExecutorGatekeeperService
|
||||
-> validates source_invocation_id / raw_path / evidence_excerpt
|
||||
-> chat_verifier
|
||||
-> judges whether verified evidence can derive claims
|
||||
-> chat_composer
|
||||
-> writes final user-facing answer
|
||||
```
|
||||
|
||||
关键行为:
|
||||
|
||||
| 角色 | 当前职责 | 输出 |
|
||||
|---|---|---|
|
||||
| `chat_planner` | 拆解问题,注入知识域地图和对话历史,给出排查方向 | `planner_plan` |
|
||||
| `chat_executor` | 按计划调用证据工具,抽取带 `source_invocation_id + raw_path + evidence_excerpt` 的微观事实 | `executor_evidence_v2` |
|
||||
| `ExecutorGatekeeperService` | 在 Verifier 前做代码级引用验真,拒绝伪造 ID、错配 raw_path、错配 excerpt | `gatekeeper_result` |
|
||||
| `chat_verifier` | 只判断已验真 evidence excerpt 是否能推出 claim,不做新检索 | `verifier_output` |
|
||||
| `chat_composer` | 只表达 Verifier 允许输出的 claims、缺口和建议,生成最终用户答复 | `composer_output` |
|
||||
|
||||
Chat 链路最多支持两轮验证:
|
||||

|
||||
Agent->>Tool: tool name + framework tool_call_id + typed args

SG-->>App: SUPPORTED / UNSUPPORTED
|
||||
App->>Release: decide public content
|
||||
Release-->>App: report or fixed fallback
|
||||
```
|
||||
|
||||
决策语义:
|
||||
## 4. PreviousTurn
|
||||
|
||||
| Verdict | 行为 |
|
||||
|---|---|
|
||||
| `PASS` | 把 Verifier 允许表达的 claims 交给 Composer 输出 |
|
||||
| `LOW_CONFID` | 如果分数低于阈值且仍有轮次,构造 `retry_context` 补证据;否则输出低置信提示 |
|
||||
| `REJECT` | 输出降级答复,只保留已确认信息和下一步建议 |
|
||||
|
||||
## 4. AIOps 编排
|
||||
|
||||
AIOps 使用 `SupervisorAgent` 调度两个子 Agent:
|
||||
|
||||
```text
|
||||
ai_ops_supervisor
|
||||
-> planner_agent
|
||||
-> executor_agent
|
||||
-> final report
|
||||
-> AiOpsRuleEvaluationService
|
||||
```
|
||||
|
||||
与 Chat 的差异:
|
||||
|
||||
- AIOps 的输入可能是结构化告警 payload。
|
||||
- payload 模式会进入 `PAYLOAD_TARGETED`,最终报告必须聚焦输入告警。
|
||||
- 无 payload 时进入 `AUTO_DISCOVERY`,先通过告警工具发现活跃告警。
|
||||
- 当前 AIOps 不使用 LLM Verifier,而使用轻量规则评估器写入 `self_evaluation.aiops_rule_evaluation`。
|
||||
|
||||
## 5. 工具边界
|
||||
|
||||
当前 Executor 可用工具来自两类:
|
||||
|
||||
```text
|
||||
methodTools
|
||||
-> dateTimeTools
|
||||
-> lookupKnowledgeTool
|
||||
-> queryMetricsTools
|
||||
-> queryLogsTools when mock enabled
|
||||
|
||||
ToolCallbackProvider
|
||||
-> framework-discovered tools
|
||||
```
|
||||
|
||||
工具调用必须写入 `tool_invocation`。其中 `lookup_knowledge` 额外记录:
|
||||
|
||||
- L0/L1 命中数量。
|
||||
- 检索层。
|
||||
- relevance level。
|
||||
- retrieved domains。
|
||||
- dedup reason。
|
||||
|
||||
## 6. Skill / Playbook 流程
|
||||
|
||||
当前 Skill 是诊断流程编排提示,不是事实证据来源。Planner 只能看到 `SkillRegistry.listAll()` 暴露的 name/description 元数据;Executor 才能通过 Spring AI Alibaba 官方 `SkillsAgentHook` 使用 `read_skill` 读取完整 `SKILL.md`。
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
Registry["SkillRegistry<br/>active skill metadata"] --> PlannerHook["PlannerSkillMetadataHook"]
|
||||
PlannerHook --> Planner["Planner<br/>metadata only"]
|
||||
Planner --> Plan["planner_plan<br/>selected_skill + steps"]
|
||||
|
||||
Registry --> ExecutorHook["SkillsAgentHook"]
|
||||
ExecutorHook --> ReadSkill["read_skill"]
|
||||
Plan --> Executor["Executor"]
|
||||
Executor --> ReadSkill
|
||||
ReadSkill --> SkillBody["SKILL.md workflow"]
|
||||
SkillBody --> Executor
|
||||
Executor --> EvidenceTools["lookup_knowledge / logs / metrics"]
|
||||
EvidenceTools --> ToolTrace["tool_invocation evidence"]
|
||||
Executor --> Gatekeeper["Gatekeeper"]
|
||||
Gatekeeper --> Verifier["Verifier"]
|
||||
ToolTrace --> Verifier
|
||||
Verifier --> Composer["Composer"]
|
||||
```
|
||||
|
||||
| 角色 | Skill 可见性 | 工具权限 |
|
||||
|---|---|---|
|
||||
| Planner | 只看 skill name / description,并输出 `selected_skill` | 不暴露 `read_skill` |
|
||||
| Executor | 读取 Planner 选中的 skill 正文 | 暴露官方 `read_skill` 和证据工具 |
|
||||
| Gatekeeper | 不看 skill catalog,也不读 skill 正文 | 只读取 Executor 输出和 `tool_invocation.retrieval_details.evidence_refs` |
|
||||
| Verifier | 不看 skill catalog,也不读 skill 正文 | 只读取 Gatekeeper 结果、结构化 claims 和 trace summary |
|
||||
| Composer | 不看 skill catalog,也不读 skill 正文 | 只读取 Verifier 允许表达的内容 |
|
||||
|
||||
## 7. 与旧版设计的差异
|
||||
|
||||
| 旧版设想 | 当前实现 |
|
||||
|---|---|
|
||||
| Supervisor + Planner + 多个专科 SubAgent + Verifier | Chat: Planner + Executor + Gatekeeper + Verifier + Composer;AIOps: Supervisor + Planner + Executor |
|
||||
| ExternalApiSubAgent / InternalErrorSubAgent / DatabaseSubAgent | 暂未拆分,能力通过通用 Executor + 工具 + Prompt 约束实现 |
|
||||
| 每个 SubAgent 专属工具集 | 当前 Executor 持有统一证据工具集合 |
|
||||
| Verifier 支持 PASS / REVISE / REJECT | 当前 Chat Verifier 输出 PASS / LOW_CONFID / REJECT |
|
||||
| Skill 驱动不同诊断流程 | 当前以 Planner 元数据选择 + Executor 读取 playbook 的方式接入 |
|
||||
|
||||
## 8. 后续演进
|
||||
|
||||
当诊断场景和工具复杂度继续上升时,再考虑拆分:
|
||||
|
||||
- `ExternalApiSubAgent`:接口文档、错误码、请求参数、第三方日志。
|
||||
- `DatabaseSubAgent`:连接池、慢 SQL、死锁、索引建议。
|
||||
- `CacheSubAgent`:Redis 超时、连接、热点 key、内存风险。
|
||||
- `GenericDiagnosisSubAgent`:专项 Agent 失败后的兜底。
|
||||
|
||||
拆分前提:
|
||||
|
||||
- 当前 Executor prompt 已难以维护。
|
||||
- 不同故障类型的工具权限明显不同。
|
||||
- Trace 能证明某类问题需要独立的推理策略。
|
||||
- 评测集能覆盖拆分前后的行为差异。
|
||||
PreviousTurn 只来自同一 Session 最近一个 `DIAGNOSIS + SUCCESS + published_result`。Fallback、失败、取消、raw evidence 和完整历史都不能进入下一轮;字段与字节上限由 Harness 配置控制。

# Agent 编排架构
|
||||
|
||||
**更新日期**:2026-07-08
|
||||
**状态**:当前可运行架构
|
||||
**参考历史文档**:`archive/2026-07-05-legacy/agent-architecture.md`
|
||||
|
||||
## 1. 设计定位
|
||||
|
||||
旧版 Agent 架构把系统描述为 Supervisor、Planner、SubAgent、Verifier 的团队协作。当前 MVP 保留这个核心思想,但实现更收敛:
|
||||
|
||||
- Chat 链路使用固定顺序工作流:`Planner -> Executor -> Gatekeeper -> Verifier -> Composer`。
|
||||
- AIOps 链路使用 `SupervisorAgent` 调度 `Planner + Executor`,最终由规则评估器做轻量验证。
|
||||
- 当前没有拆分 ExternalApiSubAgent、InternalErrorSubAgent、DatabaseSubAgent;这些作为后续演进方向保留。
|
||||
- 证据工具不直接散落在各个 Agent 里,而是通过 Spring AI ToolCallback / `@Tool` 统一暴露。
|
||||
|
||||
## 2. 当前 Agent 全景

|

```
|
||||
|
||||
## 3. Chat 编排
|
||||
|
||||
Chat 复杂诊断采用 `SequentialAgent`,顺序固定:
|
||||
|
||||
```text
|
||||
chat_planner
|
||||
-> chat_executor
|
||||
-> lookup_knowledge / query_logs / query_metrics / date_time
|
||||
-> outputs executor_evidence_v2
|
||||
-> VerifierInputHook / ExecutorGatekeeperService
|
||||
-> validates source_invocation_id / raw_path / evidence_excerpt
|
||||
-> chat_verifier
|
||||
-> judges whether verified evidence can derive claims
|
||||
-> chat_composer
|
||||
-> writes final user-facing answer
|
||||
```
|
||||
|
||||
关键行为:
|
||||
|
||||
| 角色 | 当前职责 | 输出 |
|
||||
|---|---|---|
|
||||
| `chat_planner` | 拆解问题,注入知识域地图和对话历史,给出排查方向 | `planner_plan` |
|
||||
| `chat_executor` | 按计划调用证据工具,抽取带 `source_invocation_id + raw_path + evidence_excerpt` 的微观事实 | `executor_evidence_v2` |
|
||||
| `ExecutorGatekeeperService` | 在 Verifier 前做代码级引用验真,拒绝伪造 ID、错配 raw_path、错配 excerpt | `gatekeeper_result` |
|
||||
| `chat_verifier` | 只判断已验真 evidence excerpt 是否能推出 claim,不做新检索 | `verifier_output` |
|
||||
| `chat_composer` | 只表达 Verifier 允许输出的 claims、缺口和建议,生成最终用户答复 | `composer_output` |
|
||||
|
||||
Chat 链路最多支持两轮验证:
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
autonumber
|
||||
participant C as ChatService
|
||||
participant P as chat_planner
|
||||
participant E as chat_executor
|
||||
participant T as tools
|
||||
participant G as gatekeeper
|
||||
participant V as chat_verifier
|
||||
participant M as chat_composer
|
||||
participant R as diagnosis_run
|
||||
|
||||
C->>P: 原始问题 + history + retry_context
|
||||
P-->>C: planner_plan
|
||||
C->>E: planner_plan + 上下文
|
||||
E->>T: 调用证据工具
|
||||
T-->>E: 证据结果
|
||||
E-->>C: executor_evidence_v2
|
||||
C->>G: executor_structured_output + tool_invocation.evidence_refs
|
||||
G-->>C: gatekeeper_result
|
||||
C->>V: executor_structured_output + gatekeeper_result + tool_trace_summary
|
||||
V-->>C: PASS / LOW_CONFID / REJECT
|
||||
C->>R: 写入 verifier_evaluation
|
||||
alt LOW_CONFID 且允许补证据
|
||||
C->>P: retry_context: 仅补缺失证据
|
||||
else PASS 或 REJECT
|
||||
C->>M: allowed_claims + missing_info + recommended_actions
|
||||
M-->>C: composer_output
|
||||
C->>R: 保存 Composer 最终 answer
|
||||
end
|
||||
```
|
||||
|
||||
决策语义:
|
||||
|
||||
| Verdict | 行为 |
|
||||
|---|---|
|
||||
| `PASS` | 把 Verifier 允许表达的 claims 交给 Composer 输出 |
|
||||
| `LOW_CONFID` | 如果分数低于阈值且仍有轮次,构造 `retry_context` 补证据;否则输出低置信提示 |
|
||||
| `REJECT` | 输出降级答复,只保留已确认信息和下一步建议 |
|
||||
|
||||
## 4. AIOps 编排
|
||||
|
||||
AIOps 使用 `SupervisorAgent` 调度两个子 Agent:
|
||||
|
||||
```text
|
||||
ai_ops_supervisor
|
||||
-> planner_agent
|
||||
-> executor_agent
|
||||
-> final report
|
||||
-> AiOpsRuleEvaluationService
|
||||
```
|
||||
|
||||
与 Chat 的差异:
|
||||
|
||||
- AIOps 的输入可能是结构化告警 payload。
|
||||
- payload 模式会进入 `PAYLOAD_TARGETED`,最终报告必须聚焦输入告警。
|
||||
- 无 payload 时进入 `AUTO_DISCOVERY`,先通过告警工具发现活跃告警。
|
||||
- 当前 AIOps 不使用 LLM Verifier,而使用轻量规则评估器写入 `self_evaluation.aiops_rule_evaluation`。
|
||||
|
||||
## 5. 工具边界
|
||||
|
||||
当前 Executor 可用工具来自两类:
|
||||
|
||||
```text
|
||||
methodTools
|
||||
-> dateTimeTools
|
||||
-> lookupKnowledgeTool
|
||||
-> queryMetricsTools
|
||||
-> queryLogsTools when mock enabled
|
||||
|
||||
ToolCallbackProvider
|
||||
-> framework-discovered tools
|
||||
```
|
||||
|
||||
工具调用必须写入 `tool_invocation`。其中 `lookup_knowledge` 额外记录:
|
||||
|
||||
- L0/L1 命中数量。
|
||||
- 检索层。
|
||||
- relevance level。
|
||||
- retrieved domains。
|
||||
- dedup reason。
|
||||
|
||||
## 6. Skill / Playbook 流程
|
||||
|
||||
当前 Skill 是诊断流程编排提示,不是事实证据来源。Planner 只能看到 `SkillRegistry.listAll()` 暴露的 name/description 元数据;Executor 才能通过 Spring AI Alibaba 官方 `SkillsAgentHook` 使用 `read_skill` 读取完整 `SKILL.md`。
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
Registry["SkillRegistry<br/>active skill metadata"] --> PlannerHook["PlannerSkillMetadataHook"]
|
||||
PlannerHook --> Planner["Planner<br/>metadata only"]
|
||||
Planner --> Plan["planner_plan<br/>selected_skill + steps"]
|
||||
|
||||
Registry --> ExecutorHook["SkillsAgentHook"]
|
||||
ExecutorHook --> ReadSkill["read_skill"]
|
||||
Plan --> Executor["Executor"]
|
||||
Executor --> ReadSkill
|
||||
ReadSkill --> SkillBody["SKILL.md workflow"]
|
||||
SkillBody --> Executor
|
||||
Executor --> EvidenceTools["lookup_knowledge / logs / metrics"]
|
||||
EvidenceTools --> ToolTrace["tool_invocation evidence"]
|
||||
Executor --> Gatekeeper["Gatekeeper"]
|
||||
Gatekeeper --> Verifier["Verifier"]
|
||||
ToolTrace --> Verifier
|
||||
Verifier --> Composer["Composer"]
|
||||
```
|
||||
|
||||
| 角色 | Skill 可见性 | 工具权限 |
|
||||
|---|---|---|
|
||||
| Planner | 只看 skill name / description,并输出 `selected_skill` | 不暴露 `read_skill` |
|
||||
| Executor | 读取 Planner 选中的 skill 正文 | 暴露官方 `read_skill` 和证据工具 |
|
||||
| Gatekeeper | 不看 skill catalog,也不读 skill 正文 | 只读取 Executor 输出和 `tool_invocation.retrieval_details.evidence_refs` |
|
||||
| Verifier | 不看 skill catalog,也不读 skill 正文 | 只读取 Gatekeeper 结果、结构化 claims 和 trace summary |
|
||||
| Composer | 不看 skill catalog,也不读 skill 正文 | 只读取 Verifier 允许表达的内容 |
|
||||
|
||||
## 7. 与旧版设计的差异
|
||||
|
||||
| 旧版设想 | 当前实现 |
|
||||
|---|---|
|
||||
| Supervisor + Planner + 多个专科 SubAgent + Verifier | Chat: Planner + Executor + Gatekeeper + Verifier + Composer;AIOps: Supervisor + Planner + Executor |
|
||||
| ExternalApiSubAgent / InternalErrorSubAgent / DatabaseSubAgent | 暂未拆分,能力通过通用 Executor + 工具 + Prompt 约束实现 |
|
||||
| 每个 SubAgent 专属工具集 | 当前 Executor 持有统一证据工具集合 |
|
||||
| Verifier 支持 PASS / REVISE / REJECT | 当前 Chat Verifier 输出 PASS / LOW_CONFID / REJECT |
|
||||
| Skill 驱动不同诊断流程 | 当前以 Planner 元数据选择 + Executor 读取 playbook 的方式接入 |
|
||||
|
||||
## 8. 后续演进
|
||||
|
||||
当诊断场景和工具复杂度继续上升时,再考虑拆分:
|
||||
|
||||
- `ExternalApiSubAgent`:接口文档、错误码、请求参数、第三方日志。
|
||||
- `DatabaseSubAgent`:连接池、慢 SQL、死锁、索引建议。
|
||||
- `CacheSubAgent`:Redis 超时、连接、热点 key、内存风险。
|
||||
- `GenericDiagnosisSubAgent`:专项 Agent 失败后的兜底。
|
||||
|
||||
拆分前提:
|
||||
|
||||
- 当前 Executor prompt 已难以维护。
|
||||
- 不同故障类型的工具权限明显不同。
|
||||
- Trace 能证明某类问题需要独立的推理策略。
|
||||
- 评测集能覆盖拆分前后的行为差异。

# 当前 MVP 架构
|
||||
|
||||
**更新日期**:2026-07-08
|
||||
**状态**:当前可运行架构
|
||||
**适用范围**:Demo、面试讲解、后续迭代规划
|
||||
|
||||
## 1. 系统定位
|
||||
|
||||
SuperBizAgent MVP 不是通用 Chatbot,而是面向故障诊断的 Agent 工程项目。
|
||||
|
||||
核心目标:
|
||||
|
||||
- 支持用户主动发起的 Chat 诊断。
|
||||
- 支持 AIOps 告警触发的自动诊断。
|
||||
- 保留 Agent 的规划、执行、验证过程。
|
||||
- 工具调用必须显式、可追踪、可回放。
|
||||
- RAG 检索必须通过 `lookup_knowledge` 暴露证据链。
|
||||
- 每次诊断都沉淀 session、step、tool invocation 和 self evaluation。

|

```
|
||||
|
||||
Chat 链路的质量门禁由三段组成:Gatekeeper 先做代码级引用验真,Verifier 再做 LLM 可推导性判断,Composer 最后控制对用户的表达边界。Gatekeeper、Verifier、Composer 的输出合并到当前 `diagnosis_run.self_evaluation.verifier_evaluation`,Trace API 会展示该验证结果。
|
||||

||||

POST /api/ai_ops
|
||||
-> AiOpsService
|
||||
-> 判断是否有告警 payload
|
||||
-> PAYLOAD_TARGETED
|
||||
-> AUTO_DISCOVERY
|
||||
-> 构造 AIOps 诊断 prompt
|
||||
-> payload 模式补充 recommended lookup_knowledge query
|
||||
-> Agent 编排
|
||||
-> Planner / Executor
|
||||
-> Prometheus / logs / knowledge tools
|
||||
-> 生成告警分析报告
|
||||
-> AiOpsRuleEvaluationService
|
||||
-> 合并 diagnosis_run.self_evaluation.aiops_rule_evaluation
|
||||
-> Trace API 可查看全链路
|
||||
```
|
||||
|
||||
AIOps 保留两种模式:
|
||||
|
||||
| 模式 | 触发条件 | 行为 |
|
||||
|---|---|---|
|
||||
| `PAYLOAD_TARGETED` | 请求包含 alertName、service、severity、description、timeRange 等字段 | 以 payload 为唯一主诊断对象,并生成推荐知识库 query |
|
||||
| `AUTO_DISCOVERY` | 请求没有明确告警 payload | 先查询当前活跃告警,再选择目标排查 |
|
||||
|
||||
AIOps 当前使用轻量规则验证器,重点检查:
|
||||
|
||||
- 最终报告是否存在。
|
||||
- payload 模式是否聚焦输入告警。
|
||||
- 是否使用关键证据工具,例如 `lookup_knowledge`、日志、指标。
|
||||
|
||||
关键代码:
|
||||
|
||||
- `src/main/java/com/superbiz/agent/service/AiOpsService.java`
|
||||
- `src/main/java/com/superbiz/agent/service/AiOpsRuleEvaluationService.java`
|
||||
|
||||
## 5. RAG 位置
|
||||
|
||||
RAG 不是隐藏在 Chat Advisor 里的隐式能力,而是 Executor 可以显式调用的工具:
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
Executor["Executor Agent"] --> Tool["lookup_knowledge Tool"]
|
||||
Tool --> L0["L0 domain/entity hint"]
|
||||
Tool --> Search["VectorSearchService"]
|
||||
L0 --> Search
|
||||
Search --> VectorStore["Spring AI VectorStore"]
|
||||
Search --> Fallback["Milvus SDK fallback"]
|
||||
VectorStore --> Normalize["score/rawScore/scoreLabel"]
|
||||
Fallback --> Normalize
|
||||
Normalize --> Evidence["evidence output"]
|
||||
Evidence --> Invocation["tool_invocation"]
|
||||
Evidence --> Executor
|
||||
```
|
||||
|
||||
```text
|
||||
Executor
|
||||
-> lookup_knowledge(query)
|
||||
-> L0 domain/entity hint
|
||||
-> VectorSearchService
|
||||
-> Spring AI VectorStore
|
||||
-> Milvus SDK fallback
|
||||
-> evidence shaping
|
||||
-> tool_invocation
|
||||
```
|
||||
|
||||
保留显式工具的原因:
|
||||
|
||||
- Agent 何时检索、检索什么、证据是什么,必须能在 trace 中解释。
|
||||
- AIOps payload 到 query 的业务映射需要项目内控制。
|
||||
- `tool_invocation` 是后续评测、回放和面试讲解的核心材料。
|
||||
|
||||
RAG 总体设计见 [rag-architecture.md](rag-architecture.md),检索运行细节见 [retrieval-observability.md](retrieval-observability.md)。
|
||||
|
||||
## 6. 持久化模型
|
||||
|
||||
当前诊断持久化以 session/run/trace 明细为核心:
|
||||
|
||||
```text
|
||||
chat_session
|
||||
-> 多轮会话目录和元数据
|
||||
-> session_id / status / message_pair_count
|
||||
|
||||
diagnosis_run
|
||||
-> 一次诊断运行的主记录
|
||||
-> run_id / session_id
|
||||
-> query / status / agent_flow / answer
|
||||
-> self_evaluation
|
||||
-> step_count / tool_call_count / duration
|
||||
|
||||
agent_step
|
||||
-> Agent 模型调用步骤
|
||||
-> session_id / run_id
|
||||
-> step_index / agent_name
|
||||
-> model_input / model_output / thought
|
||||
-> duration / token_count
|
||||
|
||||
tool_invocation
|
||||
-> 工具调用事实
|
||||
-> session_id / run_id
|
||||
-> tool_name / input_params / output_preview
|
||||
-> retrieval_layer / retrieval_details
|
||||
-> retrieval_details.evidence_refs
|
||||
-> relevance_level / dedup_reason
|
||||
-> duration / success
|
||||
```
|
||||
|
||||
说明:
|
||||
|
||||
- 旧的 `diagnosis_record` 已不是当前主模型。
|
||||
- `diagnosis_session` 已降级为历史兼容和回滚表,新执行写入 `chat_session + diagnosis_run`。
|
||||
- `api_document` 仍用于文档元数据管理。
|
||||
- 文档向量内容存放在 Milvus/Zilliz collection 中。
|
||||
|
||||
会话和 Trace 生命周期见 [session-trace-lifecycle.md](session-trace-lifecycle.md),完整数据关系见 [data-model.md](data-model.md)。
|
||||
|
||||
## 7. Trace API
|
||||
|
||||
```text
|
||||
GET /api/diagnosis/{sessionId}/trace
|
||||
GET /api/diagnosis/{sessionId}/trace?runId=run-...
|
||||
```
|
||||
|
||||
Trace API 聚合:
|
||||
|
||||
- 会话元数据、运行状态和最终报告。
|
||||
- Agent step 序列。
|
||||
- 工具调用和检索细节。
|
||||
- Chat Gatekeeper / Verifier / Composer 结果。
|
||||
- AIOps rule evaluation 结果。
|
||||
|
||||
Trace 是本项目区别于普通问答系统的关键:答案不是孤立文本,而是可以追溯到 Agent 决策、工具调用和证据来源。
|
||||
|
||||
Prompt、Hook、Gatekeeper、Verifier、Composer 和评测门禁的完整说明见 [harness-quality-gates.md](harness-quality-gates.md),用户反馈与 `self_evaluation` 闭环见 [feedback-architecture.md](feedback-architecture.md)。
|
||||
|
||||
## 8. 质量门禁
|
||||
|
||||
当前质量门禁分层如下:
|
||||
|
||||
| 门禁 | 位置 | 作用 |
|
||||
|---|---|---|
|
||||
| Executor Gatekeeper | `VerifierInputHook` / `ExecutorGatekeeperService` | 校验 Executor 引用的 invocation、`raw_path`、`evidence_excerpt` 是否真实 |
|
||||
| Chat Verifier | `ChatService` | 判断已验真证据是否能推出 Executor claims |
|
||||
| Chat Composer | `ChatService` | 只表达 Verifier 允许输出的内容,避免把 no-evidence 说成已排除 |
|
||||
| AIOps Rule Evaluation | `AiOpsRuleEvaluationService` | 校验告警诊断是否聚焦 payload 并使用证据 |
|
||||
| Diagnosis Eval Baseline | `mvp/eval/` | 固化诊断 trace 和报告行为 |
|
||||
| RAG Retrieval Baseline | `eval/rag-retrieval/` | 固化检索召回行为,避免 RAG 重构回退 |
|
||||
| Live RAG Acceptance | `scripts/eval_rag_live_acceptance.py` | 在运行环境中验证重建索引后的真实检索 |
|
||||
|
||||
## 9. 当前完成状态
|
||||
|
||||
已经完成:
|
||||
|
||||
- Chat 和 AIOps 两条入口链路。
|
||||
- 显式 `lookup_knowledge` Agent Tool。
|
||||
- L0 从最终决策降级为 domain/entity hint。
|
||||
- `VectorSearchService` 作为稳定检索门面。
|
||||
- Spring AI VectorStore 读取路径。
|
||||
- Milvus SDK fallback。
|
||||
- `score` / `rawScore` / `scoreLabel` 分数语义拆分。
|
||||
- `title`、`breadcrumb`、`content` 参与 embedding 文本。
|
||||
- `tool_invocation` 记录检索层、relevance level、dedup reason。
|
||||
- Chat verifier 和 AIOps rule evaluation 合并进 `self_evaluation`。
|
||||
- Chat Executor 结构化输出 `executor_evidence_v2`,不再直接承担最终用户答复。
|
||||
- `tool_invocation.retrieval_details.evidence_refs` 支持 `raw_path` 精确引用和 `$.no_evidence` 负向证据。
|
||||
- Gatekeeper 对 Executor 引用做代码级验真,并在审计中记录 `rule_set_version` 和规则元数据摘要。
|
||||
- Verifier 只判断可推导性。
|
||||
- Composer 在 Verifier 之后生成最终用户表达,并限制 negative observation 过度表述。
|
||||
- RAG offline baseline 和 live acceptance 脚本。
|
||||
|
||||
暂不作为当前已完成能力声明:
|
||||
|
||||
- 完整 QueryTransformer / MultiQuery。
|
||||
- BM25、RRF、cross-encoder rerank。
|
||||
- 完整邻居 chunk / section context expansion。
|
||||
- VectorStore 写入路径全面迁移。
|
||||
- 完整 LLM-based AIOps verifier。
|
||||
|
||||
后续 Agent 拆分、Skill/Playbook、MCP 工具协议化和进程隔离等方向见 [evolution-roadmap.md](evolution-roadmap.md)。

# Harness 与质量门禁架构
|
||||
|
||||
**更新日期**:2026-07-08
|
||||
**状态**:当前可运行架构 + 后续门禁规划
|
||||
**参考历史文档**:`archive/2026-07-05-legacy/agent-architecture.md`
|
||||
|
||||
## 1. 设计目标
|
||||
|
||||
Agent 系统的核心风险不是“没有答案”,而是:
|
||||
|
||||
- 答案引用了不存在的证据。
|
||||
- 工具调用失败后仍然编造结论。
|
||||
- 检索结果相关性不足但被当作强证据。
|
||||
- 多轮诊断重复检索同一文档,浪费上下文。
|
||||
- 最终报告无法回放执行过程。
|
||||
|
||||
因此当前 MVP 的 Harness 不是单个组件,而是一组约束:
|
||||
|
||||
```text
|
||||
Prompt contract
|
||||
+ Tool boundary
|
||||
+ Agent hooks
|
||||
+ Trace persistence
|
||||
+ Gatekeeper deterministic validation
|
||||
+ Verifier / rule evaluation
|
||||
+ Eval baseline
|
||||
```
|
||||
|
||||
## 2. Harness 总图

||||

|
||||
```
|
||||
|
||||
## 3. Prompt Contract
|
||||
|
||||
当前 Prompt 按角色拆分:
|
||||
|
||||
| Prompt | 用途 |
|
||||
|---|---|
|
||||
| `supervisor-prompt.md` | AIOps Supervisor 调度 Planner / Executor |
|
||||
| `planner-prompt.md` | AIOps Planner 规划、再规划、输出告警报告 |
|
||||
| `executor-prompt.md` | AIOps Executor 按步骤调用工具 |
|
||||
| `chat-planner-prompt.md` | Chat 复杂问题规划 |
|
||||
| `chat-executor-prompt.md` | Chat 执行工具并输出 `executor_evidence_v2` 微观事实 |
|
||||
| `chat-verifier-prompt.md` | 基于 Gatekeeper 已验真的证据判断 claims 是否可推出 |
|
||||
| `chat-composer-prompt.md` | 基于 Verifier 允许表达的内容生成最终用户答复 |
|
||||
|
||||
Prompt 层当前承担的门禁:
|
||||
|
||||
- 禁止凭记忆回答错误码、接口定义、排障步骤。
|
||||
- 需要外部信息时必须调用工具。
|
||||
- 工具连续失败或返回空结果时,最终报告必须诚实说明。
|
||||
- Chat Executor 不允许在窄范围问题中扩展根因、风险或修复建议。
|
||||
- Chat Verifier 不允许做新检索,只能判断已验真证据是否可推出 claims。
|
||||
- Chat Composer 不允许补事实,尤其不能把 `$.no_evidence` 表达为“已排除/确认没有”。
|
||||
- AIOps payload 模式必须聚焦输入告警。
|
||||
|
||||
Chat 链路还会在 `verifier_evaluation.prompt_audit` 中持久化紧凑 Prompt 审计快照:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": "chat-prompts-v1",
|
||||
"prompts": [
|
||||
{
|
||||
"name": "chat_executor",
|
||||
"version": "chat-executor-v2",
|
||||
"resource": "prompts/chat-executor-prompt.md"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
该快照只保存版本和资源路径,不保存完整 Prompt 文本。它用于面试演示、trace 回放和离线 baseline 解释“本次诊断使用了哪套 Prompt 契约”。
|
||||
|
||||
## 4. Trace Hooks
|
||||
|
||||
`AgentLoggingHook` 是当前 Agent step 可观测性的核心。
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
autonumber
|
||||
participant A as Agent
|
||||
participant H as AgentLoggingHook
|
||||
participant DB as agent_step
|
||||
|
||||
A->>H: before_model(messages, sessionId, runId)
|
||||
H->>DB: 写入 session_id / run_id / model_input / step_index / agent_name
|
||||
A-->>A: LLM 推理
|
||||
A->>H: after_model(messages, sessionId, runId)
|
||||
H->>DB: 回填 model_output / thought / has_tool_call / duration / token_count
|
||||
```
|
||||
|
||||
记录内容:
|
||||
|
||||
- 最近输入消息摘要。
|
||||
- Agent 输出摘要。
|
||||
- 是否包含 tool call。
|
||||
- duration。
|
||||
- token count。
|
||||
- Verifier 的 JSON 输出摘要。
|
||||
|
||||
新写入必须带 `run_id`;`session_id` 仍保留用于粗粒度排查和历史兼容。
|
||||
|
||||
## 5. Tool Invocation 门禁
|
||||
|
||||
工具调用记录由 `ToolInvocationRecorder` 和具体工具共同完成。
|
||||
|
||||
核心记录:
|
||||
|
||||
```text
|
||||
tool_name
|
||||
input_params
|
||||
output_preview
|
||||
retrieval_layer
|
||||
l0_match_count
|
||||
l1_match_count
|
||||
retrieval_details
|
||||
-> evidence_refs
|
||||
relevance_level
|
||||
dedup_reason
|
||||
duration_ms
|
||||
success
|
||||
error_message
|
||||
```
|
||||
|
||||
对 `lookup_knowledge` 的质量约束:
|
||||
|
||||
- L0 只作为 hint,不绕过 L1。
|
||||
- 检索结果归一化为 `PRECISE`、`HIGHLY_RELEVANT`、`REFERENCE`。
|
||||
- 同 session 内重复文档会被 `RetrievedDocTracker` 去重。
|
||||
- dedup、no evidence、failed 等状态进入 `retrieval_details.evidence_status`。
|
||||
- `retrieval_details.evidence_refs` 记录可被 Executor 引用的最小证据文本,格式为 `raw_path + text`。
|
||||
- no-hit / no-evidence 工具结果会生成 `raw_path=$.no_evidence` 的负向证据引用,语义仅限“本次查询未检索到匹配证据”。
|
||||
|
||||
## 6. Gatekeeper 与 Verifier 门禁
|
||||
|
||||
Chat Verifier 前置一层 Gatekeeper。Gatekeeper 不调用 LLM,只用代码检查 Executor 输出的证据引用是否真实存在。
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
Invocation["tool_invocation"] --> EvidenceRefs["retrieval_details.evidence_refs"]
|
||||
ExecutorOutput["executor_evidence_v2"] --> Gatekeeper["ExecutorGatekeeperService"]
|
||||
EvidenceRefs --> Gatekeeper
|
||||
Gatekeeper --> GateResult["gatekeeper_result"]
|
||||
Invocation --> Summary["ToolTraceSummaryService"]
|
||||
Summary --> EvidenceIndex["tool_trace_summary"]
|
||||
GateResult --> Verifier["chat_verifier"]
|
||||
ExecutorOutput --> Verifier
|
||||
EvidenceIndex --> Verifier
|
||||
Verifier --> Verdict{"verdict"}
|
||||
Verdict -->|PASS| Composer["chat_composer"]
|
||||
Composer --> Pass["输出最终答复"]
|
||||
Verdict -->|LOW_CONFID| Low["补证据或低置信输出"]
|
||||
Verdict -->|REJECT| Reject["降级输出"]
|
||||
```
|
||||
|
||||
Gatekeeper 检查:
|
||||
|
||||
| 检查 | 失败语义 |
|
||||
|---|---|
|
||||
| `answer_version=executor_evidence_v2` | 非结构化或旧结构输出降为低置信 |
|
||||
| `source_invocation_id` 真实存在 | 伪造 ID 直接拒绝 |
|
||||
| `tool_name` 与 invocation 对齐 | 张冠李戴直接拒绝 |
|
||||
| `raw_path` 存在于 `evidence_refs` | 无中生有直接拒绝 |
|
||||
| `evidence_excerpt` 由 `evidence_refs[].text` 支撑 | excerpt 编造或错配直接拒绝 |
|
||||
| `negative_observation` 只能引用 `$.no_evidence` | 用正向日志证明“没查到”直接拒绝 |
|
||||
|
||||
Gatekeeper 审计还会记录 `rule_set_version` 和已启用规则元数据摘要。当前规则元数据来自本地 `gatekeeper-rules.json`,规则执行仍是确定性 Java 代码。
|
||||
|
||||
Verifier 输出:
|
||||
|
||||
```json
|
||||
{
|
||||
"verdict": "PASS|LOW_CONFID|REJECT",
|
||||
"groundedness_score": 0.8,
|
||||
"critical_fact_count": 2,
|
||||
"claim_checks": [],
|
||||
"facts_checked": [],
|
||||
"rationale": "..."
|
||||
}
|
||||
```
|
||||
|
||||
Verifier 不再逐字核验 excerpt 真伪;这由 Gatekeeper 完成。Verifier 只回答一个问题:`claim_text` 是否能由已经验真的 `evidence_excerpt` 推导出来。
|
||||
|
||||
结果写入:
|
||||
|
||||
```text
|
||||
diagnosis_run.self_evaluation.verifier_evaluation
|
||||
```
|
||||
|
||||
其中同时持久化 `executor_structured_output`、`gatekeeper_result`、`tool_trace_summary`、`prompt_audit` 和 `composer_output`,用于 Trace 回放。
|
||||
|
||||
## 7. AIOps 规则门禁
|
||||
|
||||
AIOps 当前不走 Chat Verifier,而是用 `AiOpsRuleEvaluationService` 做轻量检查。
|
||||
|
||||
检查重点:
|
||||
|
||||
- 最终报告是否存在。
|
||||
- payload 模式是否围绕输入告警展开。
|
||||
- 是否调用证据工具,尤其是 `lookup_knowledge`、日志、指标。
|
||||
- 是否把无关活跃告警扩展成主诊断对象。
|
||||
|
||||
结果写入:
|
||||
|
||||
```text
|
||||
diagnosis_run.self_evaluation.aiops_rule_evaluation
|
||||
```
|
||||
|
||||
## 8. Eval Baseline
|
||||
|
||||
当前质量门禁还包括离线评测资产:
|
||||
|
||||
| 评测 | 位置 | 作用 |
|
||||
|---|---|---|
|
||||
| Diagnosis eval | `mvp/eval/` | 检查诊断 trace、报告和证据行为 |
|
||||
| RAG retrieval eval | `eval/rag-retrieval/` | 检查固定检索 query 的召回稳定性 |
|
||||
| Live RAG acceptance | `scripts/eval_rag_live_acceptance.py` | 检查运行环境中真实 `/api/search/similar` 行为 |
|
||||
|
||||
## 9. 后续门禁规划
|
||||
|
||||
从旧版设计继承但尚未完整实现的门禁:
|
||||
|
||||
- 工具参数 schema 校验。
|
||||
- 同一工具调用次数上限。
|
||||
- 工具超时的统一熔断。
|
||||
- Gatekeeper 规则远程化或三层分离:索引层、元数据层、规则实现层。
|
||||
- Prompt 版本回滚和更细粒度变更审计。
|
||||
- Verifier 对 AIOps 报告的 LLM 级事实校验。
|
||||
|
||||
这些应在评测集扩大后逐步加入,避免一次性把诊断流程卡得过死。

|
||||
## 1. 定位
|
||||
|
||||
当前 MVP 把“会话态”和“运行态”拆开:
|
||||
|
||||
```text
|
||||
chat_session(sessionId)
|
||||
-> diagnosis_run(runId)
|
||||
-> agent_step(runId)
|
||||
-> tool_invocation(runId)
|
||||
```
|
||||
|
||||
- `sessionId` 表示多轮会话目录和 Redis 上下文。
|
||||
- `runId` 表示一次可回放诊断执行。
|
||||
- `DiagnosisTraceService` 聚合一个 run 的主记录、步骤和工具调用,形成可回放 Trace。
|
||||
- `diagnosis_session` 只保留为历史兼容和回滚表。
|
||||
|
||||
## 2. 生命周期总图

||||

||||

|
||||
Feedback --> Case["useful -> case_library(run_id)"]
|
||||
```
|
||||
|
||||
## 3. ID 规则
|
||||
|
||||
| ID | 来源 | 含义 |
|
||||
|---|---|---|
|
||||
| `sessionId` | Chat request `Id`、AIOps payload `sessionId`,缺失时由服务生成 | 多轮会话目录和 Redis 上下文 |
|
||||
| `runId` | 每次有效 Chat/AIOps 执行创建 | 一次诊断运行和 Trace 回放边界 |
|
||||
|
||||
设计含义:
|
||||
|
||||
- 同一个 `sessionId` 可以贯穿多轮 Chat。
|
||||
- 每次有效 Chat/AIOps 执行都会创建新的 `runId`。
|
||||
- Trace 和 Feedback 新客户端应传 `runId`;只传 `sessionId` 时兼容解析 latest run。
|
||||
- latest run 排序使用 `diagnosis_run.created_at DESC, id DESC`,不使用 `updated_at`。
|
||||
|
||||
## 4. 运行状态流转
|
||||
|
||||
```mermaid
|
||||
stateDiagram-v2
|
||||
[*] --> PENDING
|
||||
PENDING --> RUNNING: start diagnosis
|
||||
RUNNING --> SUCCESS: workflow completed
|
||||
RUNNING --> FAILED: exception / empty state
|
||||
SUCCESS --> SUCCESS: feedback submitted
|
||||
FAILED --> FAILED: feedback submitted
|
||||
```
|
||||
|
||||
字段边界:
|
||||
|
||||
| 字段 | 所属表 | 含义 |
|
||||
|---|---|---|
|
||||
| `status` | `diagnosis_run` | 单次运行执行状态 |
|
||||
| `answer` | `diagnosis_run` | 本次运行最终报告或答复 |
|
||||
| `self_evaluation` | `diagnosis_run` | 本次运行系统自评估 JSON |
|
||||
| `feedback` | `diagnosis_run` | 本次运行用户反馈 |
|
||||
|
||||
`feedback` 不修改 `status`。一个执行成功但用户标记 `not_useful` 的 run,仍然应该是 `SUCCESS + feedback=not_useful`。
|
||||
|
||||
## 5. agent_step 写入
|
||||
|
||||
`AgentLoggingHook` 在模型调用前后写入和回填 `agent_step`。
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
autonumber
|
||||
participant Agent as Agent
|
||||
participant Hook as AgentLoggingHook
|
||||
participant DB as agent_step
|
||||
|
||||
Agent->>Hook: before_model(messages, sessionId, runId)
|
||||
Hook->>DB: insert step(session_id, run_id, model_input, step_index)
|
||||
Agent->>Hook: after_model(output, sessionId, runId)
|
||||
Hook->>DB: update model_output, duration, token_count, has_tool_call
|
||||
```
|
||||
|
||||
新写入必须带 `run_id`,同时保留 `session_id` 便于粗粒度排查。
|
||||
|
||||
## 6. tool_invocation 写入
|
||||
|
||||
工具调用记录同样通过执行上下文拿到 `sessionId + runId`:
|
||||
|
||||
```text
|
||||
ToolInvocationRecorder
|
||||
-> tool_invocation.session_id
|
||||
-> tool_invocation.run_id
|
||||
-> retrieval_details / evidence_refs
|
||||
```
|
||||
|
||||
Verifier、Gatekeeper 和 EvaluationService 应按 `run_id` 读取工具调用,避免同一 session 的其他 run 参与评分或证据校验。
|
||||
|
||||
## 7. Trace API 聚合
|
||||
|
||||
```text
|
||||
GET /api/diagnosis/{sessionId}/trace
|
||||
GET /api/diagnosis/{sessionId}/trace?runId=run-...
|
||||
```
|
||||
|
||||
聚合逻辑:
|
||||
|
||||
```text
|
||||
diagnosis_run by sessionId + runId
|
||||
+ chat_session metadata when available
|
||||
+ agent_step where run_id = runId, ordered by the Trace API
|
||||
+ tool_invocation where run_id = runId order by id
|
||||
-> DiagnosisTraceResponse
|
||||
```
|
||||
|
||||
当 `runId` 缺失时,Trace API 为兼容旧客户端解析最新 run,并在响应中返回 resolved `runId`。当 `runId` 属于其他 `sessionId` 时,API 必须拒绝,不能泄漏其他会话的 Trace。
|
||||
|
||||
## 8. Chat 与 AIOps 差异
|
||||
|
||||
| 维度 | Chat | AIOps |
|
||||
|---|---|---|
|
||||
| `agent_flow` | `CHAT` | `AI_OPS` |
|
||||
| 编排方式 | `SequentialAgent`: Planner -> Executor -> Gatekeeper -> Verifier -> Composer | `SupervisorAgent`: Planner + Executor |
|
||||
| 自评估 | `rule_evaluation` + `verifier_evaluation` | `aiops_rule_evaluation` |
|
||||
| 答案字段 | Chat 最终答复 | 告警分析报告 |
|
||||
| runId 暴露 | `/api/chat` JSON response | `/api/ai_ops` SSE metadata message |
|
||||
|
||||
## 9. 清理与边界
|
||||
|
||||
- Redis 会话历史用于多轮上下文,不是长期审计记录。
|
||||
- MySQL `diagnosis_run + agent_step + tool_invocation` 是主要可回放来源。
|
||||
- `chat_session.expires_at` 只是目录元数据;Redis 消息历史可独立过期。
|
||||
- `RetrievedDocTracker` 仍是 session 级运行时去重状态,诊断结束后清理。
|
||||
|
||||
## 10. 后续增强
|
||||
|
||||
1. Trace API 增加更结构化的 `self_evaluation` 展示。
|
||||
2. `agent_step` 与 `tool_invocation.step_id` 建立更严格关联。
|
||||
3. 旧 `diagnosis_session` 只读观察期结束后,再评估数据库层面的约束收紧或归档策略。

## 1. 系统定位
|
||||
|
||||
SuperBizAgent MVP 不是通用 Chatbot,而是面向故障诊断的 Agent 工程项目。
|
||||
SuperBizAgent 是面向故障诊断的可追踪 Agent 应用。当前系统只保留一个拥有 Tool loop 的 `Diagnosis Agent`;Harness 负责确定性的预算、取消、工具边界、证据验真、语义审查和安全发布。
|
||||
|
||||
核心目标:
|
||||
|
||||
- 支持用户主动发起的 Chat 诊断。
|
||||
- 支持 AIOps 告警触发的自动诊断。
|
||||
- 保留 Agent 的规划、执行、验证过程。
|
||||
- 工具调用必须显式、可追踪、可回放。
|
||||
- RAG 检索必须通过 `lookup_knowledge` 暴露证据链。
|
||||
- 每次诊断都沉淀 session、step、tool invocation 和 self evaluation。

Trace->>DB: 聚合 run / step / tool
|
||||
Trace-->>User: 返回可回放诊断链路
|
||||
```
|
||||
## 3. 唯一 Chat 主链
|
||||
|
||||
```text
|
||||
POST /api/chat
|
||||
-> ChatService
|
||||
-> 简单问题:轻量回答
|
||||
-> 复杂诊断:Agent 编排
|
||||
-> Planner 制定排查方向
|
||||
-> Executor 调用证据工具
|
||||
-> lookup_knowledge
|
||||
-> query_logs
|
||||
-> query_metrics
|
||||
-> Gatekeeper 校验 Executor 证据引用真实性
|
||||
-> Verifier 判断 claim 是否能由已核验证据推出
|
||||
-> Composer 生成最终用户答复
|
||||
-> 保存 chat_session metadata
|
||||
-> 保存 diagnosis_run
|
||||
-> 保存 agent_step.run_id
|
||||
-> 保存 tool_invocation.run_id
|
||||
-> 合并 diagnosis_run.self_evaluation.verifier_evaluation
|
||||
-> metadata(session_id, run_id)
|
||||
-> status*
|
||||
-> ChatApplicationUseCase
|
||||
-> SYSTEM_CHAT | KNOWLEDGE_QUERY | DIAGNOSIS
|
||||
-> content | failure
|
||||
-> done(SUCCESS | FALLBACK | FAILED)
|
||||
```
|
||||
|
||||
Chat 链路的质量门禁由三段组成:Gatekeeper 先做代码级引用验真,Verifier 再做 LLM 可推导性判断,Composer 最后控制对用户的表达边界。Gatekeeper、Verifier、Composer 的输出合并到当前 `diagnosis_run.self_evaluation.verifier_evaluation`,Trace API 会展示该验证结果。
|
||||
- Controller 只处理请求校验、bounded worker、SSE 和 disconnect。
|
||||
- Application Use Case 拥有 Session/Run、路由、PreviousTurn 和终态持久化。
|
||||
- Diagnosis Agent 是唯一报告作者和唯一拥有 evidence Tool loop 的业务 Agent。
|
||||
- EvidenceGuard 只做确定性结构/引用验真;SemanticGuard 在隔离上下文做整份报告语义审查。
|
||||
- 未通过 Release Policy 的 Draft 永不进入公开 SSE。
|
||||
|
||||
Agent 编排细节见 [agent-orchestration.md](agent-orchestration.md)。
|
||||
## 4. Tool 与数据边界
|
||||
|
||||
关键代码:
|
||||
Agent 只看到三个固定 Tool:
|
||||
|
||||
- `src/main/java/com/superbiz/agent/controller/ChatController.java`
|
||||
- `src/main/java/com/superbiz/agent/service/ChatService.java`
|
||||
- `src/main/java/com/superbiz/agent/service/SelfEvaluationMergeService.java`
|
||||
- `src/main/java/com/superbiz/agent/service/DiagnosisTraceService.java`
|
||||
- `lookup_knowledge`
|
||||
- `query_logs`
|
||||
- `query_mysql`
|
||||
|
||||
## 4. AIOps 诊断链路
|
||||
每次调用由框架提供 `tool_call_id`,Harness 校验 exact run、只读、Schema、预算和容量。Redis 保存 TTL 内完整 canonical invocation;MySQL `tool_invocation` 只保存长期有界 metadata,不保存完整参数、SQL/日志正文、raw response 或 Agent projection。
|
||||

||||

|

|
||||
```
|
||||
## 5. Trace 与持久化
|
||||
|
||||
```text
|
||||
POST /api/ai_ops
|
||||
-> AiOpsService
|
||||
-> 判断是否有告警 payload
|
||||
-> PAYLOAD_TARGETED
|
||||
-> AUTO_DISCOVERY
|
||||
-> 构造 AIOps 诊断 prompt
|
||||
-> payload 模式补充 recommended lookup_knowledge query
|
||||
-> Agent 编排
|
||||
-> Planner / Executor
|
||||
-> Prometheus / logs / knowledge tools
|
||||
-> 生成告警分析报告
|
||||
-> AiOpsRuleEvaluationService
|
||||
-> 合并 diagnosis_run.self_evaluation.aiops_rule_evaluation
|
||||
-> Trace API 可查看全链路
|
||||
chat_session(sessionId)
|
||||
-> diagnosis_run(runId)
|
||||
-> agent_step(runId)
|
||||
-> tool_invocation(runId)
|
||||
```
|
||||
|
||||
AIOps 保留两种模式:
|
||||
- `chat_session` 是 JPA Run 目录与多轮 metadata,不保存完整对话历史。
|
||||
- `diagnosis_run` 是 Run 状态、intent、release outcome、安全发布结果和预算汇总真理源。
|
||||
- `agent_step` 只保存模型步骤 metadata,不保存 Prompt、消息正文、模型正文或 Thought。
|
||||
- `tool_invocation` 只保存 Tool durable audit metadata;完整调用由 Redis canonical store 短期保存。
|
||||
|
||||
| 模式 | 触发条件 | 行为 |
|
||||
|---|---|---|
|
||||
| `PAYLOAD_TARGETED` | 请求包含 alertName、service、severity、description、timeRange 等字段 | 以 payload 为唯一主诊断对象,并生成推荐知识库 query |
|
||||
| `AUTO_DISCOVERY` | 请求没有明确告警 payload | 先查询当前活跃告警,再选择目标排查 |
|
||||
## 6. 公开 API
|
||||
|
||||
AIOps 当前使用轻量规则验证器,重点检查:
|
||||
当前诊断执行入口只有 `POST /api/chat`。Trace、feedback、文档与检索 API 保持独立;已删除的旧诊断和 Redis conversation Session endpoint 不提供兼容分支。
|
||||
|
||||
- 最终报告是否存在。
|
||||
- payload 模式是否聚焦输入告警。
|
||||
- 是否使用关键证据工具,例如 `lookup_knowledge`、日志、指标。
|
||||
## 7. 安全边界
|
||||
|
||||
关键代码:
|
||||
|
||||
- `src/main/java/com/superbiz/agent/service/AiOpsService.java`
|
||||
- `src/main/java/com/superbiz/agent/service/AiOpsRuleEvaluationService.java`
|
||||
|
||||
## 5. RAG 位置
|
||||
|
||||
RAG 不是隐藏在 Chat Advisor 里的隐式能力,而是 Executor 可以显式调用的工具:
|
||||

||||

|
||||
|
||||
保留显式工具的原因:
|
||||
|
||||
- Agent 何时检索、检索什么、证据是什么,必须能在 trace 中解释。
|
||||
- AIOps payload 到 query 的业务映射需要项目内控制。
|
||||
- `tool_invocation` 是后续评测、回放和面试讲解的核心材料。
|
||||
|
||||
RAG 总体设计见 [rag-architecture.md](rag-architecture.md),检索运行细节见 [retrieval-observability.md](retrieval-observability.md)。
|
||||
|
||||
## 6. 持久化模型
|
||||
|
||||
当前诊断持久化以 session/run/trace 明细为核心:
|
||||
|
||||
```text
|
||||
chat_session
|
||||
-> 多轮会话目录和元数据
|
||||
-> session_id / status / message_pair_count
|
||||
|
||||
diagnosis_run
|
||||
-> 一次诊断运行的主记录
|
||||
-> run_id / session_id
|
||||
-> query / status / agent_flow / answer
|
||||
-> self_evaluation
|
||||
-> step_count / tool_call_count / duration
|
||||
|
||||
agent_step
|
||||
-> Agent 模型调用步骤
|
||||
-> session_id / run_id
|
||||
-> step_index / agent_name
|
||||
-> model_input / model_output / thought
|
||||
-> duration / token_count
|
||||
|
||||
tool_invocation
|
||||
-> 工具调用事实
|
||||
-> session_id / run_id
|
||||
-> tool_name / input_params / output_preview
|
||||
-> retrieval_layer / retrieval_details
|
||||
-> retrieval_details.evidence_refs
|
||||
-> relevance_level / dedup_reason
|
||||
-> duration / success
|
||||
```
|
||||
|
||||
说明:
|
||||
|
||||
- 旧的 `diagnosis_record` 已不是当前主模型。
|
||||
- `diagnosis_session` 已降级为历史兼容和回滚表,新执行写入 `chat_session + diagnosis_run`。
|
||||
- `api_document` 仍用于文档元数据管理。
|
||||
- 文档向量内容存放在 Milvus/Zilliz collection 中。
|
||||
|
||||
会话和 Trace 生命周期见 [session-trace-lifecycle.md](session-trace-lifecycle.md),完整数据关系见 [data-model.md](data-model.md)。
|
||||
|
||||
## 7. Trace API
|
||||
|
||||
```text
|
||||
GET /api/diagnosis/{sessionId}/trace
|
||||
GET /api/diagnosis/{sessionId}/trace?runId=run-...
|
||||
```
|
||||
|
||||
Trace API 聚合:
|
||||
|
||||
- 会话元数据、运行状态和最终报告。
|
||||
- Agent step 序列。
|
||||
- 工具调用和检索细节。
|
||||
- Chat Gatekeeper / Verifier / Composer 结果。
|
||||
- AIOps rule evaluation 结果。
|
||||
|
||||
Trace 是本项目区别于普通问答系统的关键:答案不是孤立文本,而是可以追溯到 Agent 决策、工具调用和证据来源。
|
||||
|
||||
Prompt、Hook、Gatekeeper、Verifier、Composer 和评测门禁的完整说明见 [harness-quality-gates.md](harness-quality-gates.md),用户反馈与 `self_evaluation` 闭环见 [feedback-architecture.md](feedback-architecture.md)。
|
||||
|
||||
## 8. 质量门禁
|
||||
|
||||
当前质量门禁分层如下:
|
||||
|
||||
| 门禁 | 位置 | 作用 |
|
||||
|---|---|---|
|
||||
| Executor Gatekeeper | `VerifierInputHook` / `ExecutorGatekeeperService` | 校验 Executor 引用的 invocation、`raw_path`、`evidence_excerpt` 是否真实 |
|
||||
| Chat Verifier | `ChatService` | 判断已验真证据是否能推出 Executor claims |
|
||||
| Chat Composer | `ChatService` | 只表达 Verifier 允许输出的内容,避免把 no-evidence 说成已排除 |
|
||||
| AIOps Rule Evaluation | `AiOpsRuleEvaluationService` | 校验告警诊断是否聚焦 payload 并使用证据 |
|
||||
| Diagnosis Eval Baseline | `mvp/eval/` | 固化诊断 trace 和报告行为 |
|
||||
| RAG Retrieval Baseline | `eval/rag-retrieval/` | 固化检索召回行为,避免 RAG 重构回退 |
|
||||
| Live RAG Acceptance | `scripts/eval_rag_live_acceptance.py` | 在运行环境中验证重建索引后的真实检索 |
|
||||
|
||||
## 9. 当前完成状态
|
||||
|
||||
已经完成:
|
||||
|
||||
- Chat 和 AIOps 两条入口链路。
|
||||
- 显式 `lookup_knowledge` Agent Tool。
|
||||
- L0 从最终决策降级为 domain/entity hint。
|
||||
- `VectorSearchService` 作为稳定检索门面。
|
||||
- Spring AI VectorStore 读取路径。
|
||||
- Milvus SDK fallback。
|
||||
- `score` / `rawScore` / `scoreLabel` 分数语义拆分。
|
||||
- `title`、`breadcrumb`、`content` 参与 embedding 文本。
|
||||
- `tool_invocation` 记录检索层、relevance level、dedup reason。
|
||||
- Chat verifier 和 AIOps rule evaluation 合并进 `self_evaluation`。
|
||||
- Chat Executor 结构化输出 `executor_evidence_v2`,不再直接承担最终用户答复。
|
||||
- `tool_invocation.retrieval_details.evidence_refs` 支持 `raw_path` 精确引用和 `$.no_evidence` 负向证据。
|
||||
- Gatekeeper 对 Executor 引用做代码级验真,并在审计中记录 `rule_set_version` 和规则元数据摘要。
|
||||
- Verifier 只判断可推导性。
|
||||
- Composer 在 Verifier 之后生成最终用户表达,并限制 negative observation 过度表述。
|
||||
- RAG offline baseline 和 live acceptance 脚本。
|
||||
|
||||
暂不作为当前已完成能力声明:
|
||||
|
||||
- 完整 QueryTransformer / MultiQuery。
|
||||
- BM25、RRF、cross-encoder rerank。
|
||||
- 完整邻居 chunk / section context expansion。
|
||||
- VectorStore 写入路径全面迁移。
|
||||
- 完整 LLM-based AIOps verifier。
|
||||
|
||||
后续 Agent 拆分、Skill/Playbook、MCP 工具协议化和进程隔离等方向见 [evolution-roadmap.md](evolution-roadmap.md)。
|
||||
|
||||
## 10. 关键代码索引
|
||||
|
||||
| 能力 | 代码 |
|
||||
|---|---|
|
||||
| Chat 入口与编排 | `ChatController`, `ChatService` |
|
||||
| AIOps 入口与编排 | `ChatController.aiOps`, `AiOpsService` |
|
||||
| AIOps 规则验证 | `AiOpsRuleEvaluationService` |
|
||||
| 知识库工具 | `LookupKnowledgeTool` |
|
||||
| L0 hint | `KnowledgeIndexService` |
|
||||
| 向量检索门面 | `VectorSearchService` |
|
||||
| 文档切片 | `DocumentChunkService` |
|
||||
| 向量写入 | `VectorIndexService` |
|
||||
| Spring AI VectorStore 配置辅助 | `SpringAiVectorStoreSidecarService` |
|
||||
| Trace 聚合 | `DiagnosisTraceService` |
|
||||
| 工具调用记录 | `ToolInvocationRecorder` |
|
||||
| Executor 引用验真 | `ExecutorGatekeeperService`, `VerifierInputHook` |
|
||||
| self_evaluation 合并 | `SelfEvaluationMergeService` |
|
||||
- 不输出或长期持久化 Chain of Thought。
|
||||
- 不向 Agent 暴露 Redis、canonical key、完整 Tool 请求/响应或数据库凭据。
|
||||
- EvidenceGuard 只接受当前 Run 的 READY canonical invocation。
|
||||
- SemanticGuard 无 Tool、无记忆、无回调主 Agent 能力。
|
||||
- technical failure 与 guard rejection 只能产生 stable failure 或固定 safe fallback。

**更新日期**:2026-07-08
|
||||
**状态**:当前可运行架构 + 后续门禁规划
|
||||
**参考历史文档**:`archive/2026-07-05-legacy/agent-architecture.md`
|
||||
**更新日期**:2026-07-22
|
||||
**状态**:当前可运行架构
|
||||
|
||||
## 1. 设计目标
|
||||
## 1. Harness 定位
|
||||
|
||||
Agent 系统的核心风险不是“没有答案”,而是:
|
||||
Harness 是确定性执行边界,不承担业务推理。它统一管理:
|
||||
|
||||
- 答案引用了不存在的证据。
|
||||
- 工具调用失败后仍然编造结论。
|
||||
- 检索结果相关性不足但被当作强证据。
|
||||
- 多轮诊断重复检索同一文档,浪费上下文。
|
||||
- 最终报告无法回放执行过程。
|
||||
- RunContext、deadline、first-terminal-wins lifecycle 与客户端取消。
|
||||
- 模型调用、Tool 调用、Token、字节数和单 Tool 次数预算。
|
||||
- 类型化 retry policy;Diagnosis Agent 和 Tool 调用不自动重试。
|
||||
- ToolBoundary、canonical invocation 与 Agent projection。
|
||||
- EvidenceGuard、Evidence repair、SemanticGuard 与 Release Policy。
|
||||
- metadata-only durable audit。
|
||||
|
||||
因此当前 MVP 的 Harness 不是单个组件,而是一组约束:
|
||||
## 2. ToolBoundary
|
||||
|
||||
```text
|
||||
Prompt contract
|
||||
+ Tool boundary
|
||||
+ Agent hooks
|
||||
+ Trace persistence
|
||||
+ Gatekeeper deterministic validation
|
||||
+ Verifier / rule evaluation
|
||||
+ Eval baseline
|
||||
framework tool_call_id
|
||||
-> exact Run / schema / authorization / read-only / budget
|
||||
-> backend execution
|
||||
-> raw response -> Redis canonical invocation
|
||||
-> projector -> bounded agent_result
|
||||
-> ToolInvocation durable metadata audit
|
||||
-> Agent observation
|
||||
```
|
||||
|
||||
## 2. Harness 总图
|
||||
Redis canonical invocation 可在 TTL 内保存完整 request/raw_response/agent_result,受独立前缀、容量和 Harness-only 访问保护。Durable audit 只保存 identity、Tool 名、状态、耗时和字节数;audit 写入失败可观测但不改变 canonical Tool 结果。
|
||||
|
||||
```mermaid

||||

|

|
||||
Gatekeeper --> Verifier["chat_verifier"]
|
||||
TraceSummary --> Verifier
|
||||
Verifier --> SelfEval["self_evaluation.verifier_evaluation"]
|
||||
EvidenceGuard 不调用模型。它校验 Draft schema、analysis ID、当前 Run Tool ownership、READY 状态、evidence status 和每条结论的引用闭包,并生成只包含 Agent projection 的 verified snapshot。
|
||||
|
||||
Invocation --> AiOpsRule["AiOpsRuleEvaluationService"]

|
||||
Step --> TraceAPI
|
||||
Invocation --> TraceAPI
|
||||
SelfEval --> TraceAPI
|
||||
AiOpsEval --> TraceAPI
|
||||
SemanticGuard 使用隔离的单轮模型调用,只接收原始 query、完整 Draft 和 verified snapshot。它无 Tool、无记忆、不访问 Redis、不改写报告;技术失败最多按相同输入重试一次,仍失败则安全降级。
|
||||
|
||||
TraceAPI --> Eval["diagnosis eval / RAG eval"]
|
||||
```
|
||||
## 5. Release Policy
|
||||
|
||||
## 3. Prompt Contract
|
||||
- `SUPPORTED`:发布 Diagnosis Agent 原始安全 Draft 的 typed report。
|
||||
- `UNSUPPORTED` 或 evidence failure:发布固定 SAFE_FALLBACK。
|
||||
- technical failure:发布 stable failure,不泄漏内部异常。
|
||||
- cancel/timeout:结束 exact Run,禁止 late content。
|
||||
|
||||
当前 Prompt 按角色拆分:
|
||||
## 6. Audit 安全
|
||||
|
||||
| Prompt | 用途 |
|
||||
|---|---|
|
||||
| `supervisor-prompt.md` | AIOps Supervisor 调度 Planner / Executor |
|
||||
| `planner-prompt.md` | AIOps Planner 规划、再规划、输出告警报告 |
|
||||
| `executor-prompt.md` | AIOps Executor 按步骤调用工具 |
|
||||
| `chat-planner-prompt.md` | Chat 复杂问题规划 |
|
||||
| `chat-executor-prompt.md` | Chat 执行工具并输出 `executor_evidence_v2` 微观事实 |
|
||||
| `chat-verifier-prompt.md` | 基于 Gatekeeper 已验真的证据判断 claims 是否可推出 |
|
||||
| `chat-composer-prompt.md` | 基于 Verifier 允许表达的内容生成最终用户答复 |
|
||||
|
||||
Prompt 层当前承担的门禁:
|
||||
|
||||
- 禁止凭记忆回答错误码、接口定义、排障步骤。
|
||||
- 需要外部信息时必须调用工具。
|
||||
- 工具连续失败或返回空结果时,最终报告必须诚实说明。
|
||||
- Chat Executor 不允许在窄范围问题中扩展根因、风险或修复建议。
|
||||
- Chat Verifier 不允许做新检索,只能判断已验真证据是否可推出 claims。
|
||||
- Chat Composer 不允许补事实,尤其不能把 `$.no_evidence` 表达为“已排除/确认没有”。
|
||||
- AIOps payload 模式必须聚焦输入告警。
|
||||
|
||||
Chat 链路还会在 `verifier_evaluation.prompt_audit` 中持久化紧凑 Prompt 审计快照:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": "chat-prompts-v1",
|
||||
"prompts": [
|
||||
{
|
||||
"name": "chat_executor",
|
||||
"version": "chat-executor-v2",
|
||||
"resource": "prompts/chat-executor-prompt.md"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
该快照只保存版本和资源路径,不保存完整 Prompt 文本。它用于面试演示、trace 回放和离线 baseline 解释“本次诊断使用了哪套 Prompt 契约”。
|
||||
|
||||
## 4. Trace Hooks
|
||||
|
||||
`AgentLoggingHook` 是当前 Agent step 可观测性的核心。
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
autonumber
|
||||
participant A as Agent
|
||||
participant H as AgentLoggingHook
|
||||
participant DB as agent_step
|
||||
|
||||
A->>H: before_model(messages, sessionId, runId)
|
||||
H->>DB: 写入 session_id / run_id / model_input / step_index / agent_name
|
||||
A-->>A: LLM 推理
|
||||
A->>H: after_model(messages, sessionId, runId)
|
||||
H->>DB: 回填 model_output / thought / has_tool_call / duration / token_count
|
||||
```
|
||||
|
||||
记录内容:
|
||||
|
||||
- 最近输入消息摘要。
|
||||
- Agent 输出摘要。
|
||||
- 是否包含 tool call。
|
||||
- duration。
|
||||
- token count。
|
||||
- Verifier 的 JSON 输出摘要。
|
||||
|
||||
新写入必须带 `run_id`;`session_id` 仍保留用于粗粒度排查和历史兼容。
|
||||
|
||||
## 5. Tool Invocation 门禁
|
||||
|
||||
工具调用记录由 `ToolInvocationRecorder` 和具体工具共同完成。
|
||||
|
||||
核心记录:
|
||||
|
||||
```text
|
||||
tool_name
|
||||
input_params
|
||||
output_preview
|
||||
retrieval_layer
|
||||
l0_match_count
|
||||
l1_match_count
|
||||
retrieval_details
|
||||
-> evidence_refs
|
||||
relevance_level
|
||||
dedup_reason
|
||||
duration_ms
|
||||
success
|
||||
error_message
|
||||
```
|
||||
|
||||
对 `lookup_knowledge` 的质量约束:
|
||||
|
||||
- L0 只作为 hint,不绕过 L1。
|
||||
- 检索结果归一化为 `PRECISE`、`HIGHLY_RELEVANT`、`REFERENCE`。
|
||||
- 同 session 内重复文档会被 `RetrievedDocTracker` 去重。
|
||||
- dedup、no evidence、failed 等状态进入 `retrieval_details.evidence_status`。
|
||||
- `retrieval_details.evidence_refs` 记录可被 Executor 引用的最小证据文本,格式为 `raw_path + text`。
|
||||
- no-hit / no-evidence 工具结果会生成 `raw_path=$.no_evidence` 的负向证据引用,语义仅限“本次查询未检索到匹配证据”。
|
||||
|
||||
## 6. Gatekeeper 与 Verifier 门禁
|
||||
|
||||
Chat Verifier 前置一层 Gatekeeper。Gatekeeper 不调用 LLM,只用代码检查 Executor 输出的证据引用是否真实存在。
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
Invocation["tool_invocation"] --> EvidenceRefs["retrieval_details.evidence_refs"]
|
||||
ExecutorOutput["executor_evidence_v2"] --> Gatekeeper["ExecutorGatekeeperService"]
|
||||
EvidenceRefs --> Gatekeeper
|
||||
Gatekeeper --> GateResult["gatekeeper_result"]
|
||||
Invocation --> Summary["ToolTraceSummaryService"]
|
||||
Summary --> EvidenceIndex["tool_trace_summary"]
|
||||
GateResult --> Verifier["chat_verifier"]
|
||||
ExecutorOutput --> Verifier
|
||||
EvidenceIndex --> Verifier
|
||||
Verifier --> Verdict{"verdict"}
|
||||
Verdict -->|PASS| Composer["chat_composer"]
|
||||
Composer --> Pass["输出最终答复"]
|
||||
Verdict -->|LOW_CONFID| Low["补证据或低置信输出"]
|
||||
Verdict -->|REJECT| Reject["降级输出"]
|
||||
```
|
||||
|
||||
Gatekeeper 检查:
|
||||
|
||||
| 检查 | 失败语义 |
|
||||
|---|---|
|
||||
| `answer_version=executor_evidence_v2` | 非结构化或旧结构输出降为低置信 |
|
||||
| `source_invocation_id` 真实存在 | 伪造 ID 直接拒绝 |
|
||||
| `tool_name` 与 invocation 对齐 | 张冠李戴直接拒绝 |
|
||||
| `raw_path` 存在于 `evidence_refs` | 无中生有直接拒绝 |
|
||||
| `evidence_excerpt` 由 `evidence_refs[].text` 支撑 | excerpt 编造或错配直接拒绝 |
|
||||
| `negative_observation` 只能引用 `$.no_evidence` | 用正向日志证明“没查到”直接拒绝 |
|
||||
|
||||
Gatekeeper 审计还会记录 `rule_set_version` 和已启用规则元数据摘要。当前规则元数据来自本地 `gatekeeper-rules.json`,规则执行仍是确定性 Java 代码。
|
||||
|
||||
Verifier 输出:
|
||||
|
||||
```json
|
||||
{
|
||||
"verdict": "PASS|LOW_CONFID|REJECT",
|
||||
"groundedness_score": 0.8,
|
||||
"critical_fact_count": 2,
|
||||
"claim_checks": [],
|
||||
"facts_checked": [],
|
||||
"rationale": "..."
|
||||
}
|
||||
```
|
||||
|
||||
Verifier 不再逐字核验 excerpt 真伪;这由 Gatekeeper 完成。Verifier 只回答一个问题:`claim_text` 是否能由已经验真的 `evidence_excerpt` 推导出来。
|
||||
|
||||
结果写入:
|
||||
|
||||
```text
|
||||
diagnosis_run.self_evaluation.verifier_evaluation
|
||||
```
|
||||
|
||||
其中同时持久化 `executor_structured_output`、`gatekeeper_result`、`tool_trace_summary`、`prompt_audit` 和 `composer_output`,用于 Trace 回放。
|
||||
|
||||
## 7. AIOps 规则门禁
|
||||
|
||||
AIOps 当前不走 Chat Verifier,而是用 `AiOpsRuleEvaluationService` 做轻量检查。
|
||||
|
||||
检查重点:
|
||||
|
||||
- 最终报告是否存在。
|
||||
- payload 模式是否围绕输入告警展开。
|
||||
- 是否调用证据工具,尤其是 `lookup_knowledge`、日志、指标。
|
||||
- 是否把无关活跃告警扩展成主诊断对象。
|
||||
|
||||
结果写入:
|
||||
|
||||
```text
|
||||
diagnosis_run.self_evaluation.aiops_rule_evaluation
|
||||
```
|
||||
|
||||
## 8. Eval Baseline
|
||||
|
||||
当前质量门禁还包括离线评测资产:
|
||||
|
||||
| 评测 | 位置 | 作用 |
|
||||
|---|---|---|
|
||||
| Diagnosis eval | `mvp/eval/` | 检查诊断 trace、报告和证据行为 |
|
||||
| RAG retrieval eval | `eval/rag-retrieval/` | 检查固定检索 query 的召回稳定性 |
|
||||
| Live RAG acceptance | `scripts/eval_rag_live_acceptance.py` | 检查运行环境中真实 `/api/search/similar` 行为 |
|
||||
|
||||
## 9. 后续门禁规划
|
||||
|
||||
从旧版设计继承但尚未完整实现的门禁:
|
||||
|
||||
- 工具参数 schema 校验。
|
||||
- 同一工具调用次数上限。
|
||||
- 工具超时的统一熔断。
|
||||
- Gatekeeper 规则远程化或三层分离:索引层、元数据层、规则实现层。
|
||||
- Prompt 版本回滚和更细粒度变更审计。
|
||||
- Verifier 对 AIOps 报告的 LLM 级事实校验。
|
||||
|
||||
这些应在评测集扩大后逐步加入,避免一次性把诊断流程卡得过死。
|
||||
AgentStep 不保存 Prompt、消息正文、模型正文、Tool arguments 或 Thought。ToolInvocation 不保存完整 request、SQL/日志 query、raw response 或 Agent projection。应用日志不得打印这些字段。

**参考历史文档**:`archive/2026-07-05-legacy/session-management.md`
|
||||
|
||||
## 1. 定位
|
||||
## 1. Identity
|
||||
|
||||
当前 MVP 把“会话态”和“运行态”拆开:
|
||||
- `sessionId`:多轮对话目录,由客户端传入或应用生成。
|
||||
- `runId`:一次 Chat 执行,由 Harness 生成并在 SSE metadata 首事件返回。
|
||||
- 所有 Run、AgentStep、ToolInvocation 和 Trace 查询必须使用同一个 exact ID;禁止用“最新一条”替代。
|
||||
|
||||
## 2. 生命周期
|
||||
|
||||
```text
|
||||
chat_session(sessionId)
|
||||
-> diagnosis_run(runId)
|
||||
-> agent_step(runId)
|
||||
-> tool_invocation(runId)
|
||||
request accepted
|
||||
-> start RunContext
|
||||
-> persist diagnosis_run RUNNING
|
||||
-> metadata(session_id, run_id)
|
||||
-> route / execute / guard / release
|
||||
-> SUCCESS | FALLBACK | FAILED | CANCELLED
|
||||
-> persist terminal state and budget usage
|
||||
```
|
||||
|
||||
- `sessionId` 表示多轮会话目录和 Redis 上下文。
|
||||
- `runId` 表示一次可回放诊断执行。
|
||||
- `DiagnosisTraceService` 聚合一个 run 的主记录、步骤和工具调用,形成可回放 Trace。
|
||||
- `diagnosis_session` 只保留为历史兼容和回滚表。
|
||||
disconnect、timeout 与 send failure 通过同一个 `ChatRunControl` 请求取消。正常 SSE complete 在 callback 前标记 terminal,避免误取消;late content 被 state machine 拒绝。
|
||||
|
||||
## 2. 生命周期总图
|
||||
## 3. Trace 聚合
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
Start["request: chat / ai_ops"] --> Resolve["resolve sessionId"]
|
||||
Resolve --> Session["ensure chat_session metadata"]
|
||||
Session --> Run["create diagnosis_run(runId)"]
|
||||
Run --> Running["run.status = RUNNING"]
|
||||
`GET /api/diagnosis/{sessionId}/trace?runId={runId}` 聚合:
|
||||
|
||||
Running --> Agent["Agent workflow"]
|
||||
Agent --> Context["execution context(sessionId, runId)"]
|
||||
Context --> StepHook["AgentLoggingHook"]
|
||||
StepHook --> Step["agent_step(session_id, run_id)"]
|
||||
Context --> Tool["Evidence tools"]
|
||||
Tool --> Invocation["tool_invocation(session_id, run_id)"]
|
||||
Invocation --> Gatekeeper["Gatekeeper evidence validation"]
|
||||
- `chat_session` metadata。
|
||||
- exact `diagnosis_run` 状态、intent、release outcome、安全 answer 与预算。
|
||||
- `agent_step` metadata-only 模型步骤。
|
||||
- `tool_invocation` metadata-only Tool durable audit。
|
||||
|
||||
Agent --> Final{"workflow result"}
|
||||
Final -->|success| Success["run.status = SUCCESS, answer saved"]
|
||||
Final -->|failed| Failed["run.status = FAILED"]
|
||||
Redis canonical invocation 不是 Trace API 的长期响应内容;它只供当前 Run EvidenceGuard 验真。
|
||||
|
||||
Success --> Evaluation["diagnosis_run.self_evaluation merge"]
|
||||
Failed --> Evaluation
|
||||
Evaluation --> Trace["GET /api/diagnosis/{sessionId}/trace?runId=..."]
|
||||
Success --> Feedback["POST /api/feedback(sessionId, runId)"]
|
||||
Feedback --> Case["useful -> case_library(run_id)"]
|
||||
```
|
||||
## 4. PreviousTurn
|
||||
|
||||
## 3. ID 规则
|
||||
|
||||
| ID | 来源 | 含义 |
|
||||
|---|---|---|
|
||||
| `sessionId` | Chat request `Id`、AIOps payload `sessionId`,缺失时由服务生成 | 多轮会话目录和 Redis 上下文 |
|
||||
| `runId` | 每次有效 Chat/AIOps 执行创建 | 一次诊断运行和 Trace 回放边界 |
|
||||
|
||||
设计含义:
|
||||
|
||||
- 同一个 `sessionId` 可以贯穿多轮 Chat。
|
||||
- 每次有效 Chat/AIOps 执行都会创建新的 `runId`。
|
||||
- Trace 和 Feedback 新客户端应传 `runId`;只传 `sessionId` 时兼容解析 latest run。
|
||||
- latest run 排序使用 `diagnosis_run.created_at DESC, id DESC`,不使用 `updated_at`。
|
||||
|
||||
## 4. 运行状态流转
|
||||
|
||||
```mermaid
|
||||
stateDiagram-v2
|
||||
[*] --> PENDING
|
||||
PENDING --> RUNNING: start diagnosis
|
||||
RUNNING --> SUCCESS: workflow completed
|
||||
RUNNING --> FAILED: exception / empty state
|
||||
SUCCESS --> SUCCESS: feedback submitted
|
||||
FAILED --> FAILED: feedback submitted
|
||||
```
|
||||
|
||||
字段边界:
|
||||
|
||||
| 字段 | 所属表 | 含义 |
|
||||
|---|---|---|
|
||||
| `status` | `diagnosis_run` | 单次运行执行状态 |
|
||||
| `answer` | `diagnosis_run` | 本次运行最终报告或答复 |
|
||||
| `self_evaluation` | `diagnosis_run` | 本次运行系统自评估 JSON |
|
||||
| `feedback` | `diagnosis_run` | 本次运行用户反馈 |
|
||||
|
||||
`feedback` 不修改 `status`。一个执行成功但用户标记 `not_useful` 的 run,仍然应该是 `SUCCESS + feedback=not_useful`。
|
||||
|
||||
## 5. agent_step 写入
|
||||
|
||||
`AgentLoggingHook` 在模型调用前后写入和回填 `agent_step`。
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
autonumber
|
||||
participant Agent as Agent
|
||||
participant Hook as AgentLoggingHook
|
||||
participant DB as agent_step
|
||||
|
||||
Agent->>Hook: before_model(messages, sessionId, runId)
|
||||
Hook->>DB: insert step(session_id, run_id, model_input, step_index)
|
||||
Agent->>Hook: after_model(output, sessionId, runId)
|
||||
Hook->>DB: update model_output, duration, token_count, has_tool_call
|
||||
```
|
||||
|
||||
新写入必须带 `run_id`,同时保留 `session_id` 便于粗粒度排查。
|
||||
|
||||
## 6. tool_invocation 写入
|
||||
|
||||
工具调用记录同样通过执行上下文拿到 `sessionId + runId`:
|
||||
|
||||
```text
|
||||
ToolInvocationRecorder
|
||||
-> tool_invocation.session_id
|
||||
-> tool_invocation.run_id
|
||||
-> retrieval_details / evidence_refs
|
||||
```
|
||||
|
||||
Verifier、Gatekeeper 和 EvaluationService 应按 `run_id` 读取工具调用,避免同一 session 的其他 run 参与评分或证据校验。
|
||||
|
||||
## 7. Trace API 聚合
|
||||
|
||||
```text
|
||||
GET /api/diagnosis/{sessionId}/trace
|
||||
GET /api/diagnosis/{sessionId}/trace?runId=run-...
|
||||
```
|
||||
|
||||
聚合逻辑:
|
||||
|
||||
```text
|
||||
diagnosis_run by sessionId + runId
|
||||
+ chat_session metadata when available
|
||||
+ agent_step where run_id = runId, ordered by the Trace API
|
||||
+ tool_invocation where run_id = runId order by id
|
||||
-> DiagnosisTraceResponse
|
||||
```
|
||||
|
||||
当 `runId` 缺失时,Trace API 为兼容旧客户端解析最新 run,并在响应中返回 resolved `runId`。当 `runId` 属于其他 `sessionId` 时,API 必须拒绝,不能泄漏其他会话的 Trace。
|
||||
|
||||
## 8. Chat 与 AIOps 差异
|
||||
|
||||
| 维度 | Chat | AIOps |
|
||||
|---|---|---|
|
||||
| `agent_flow` | `CHAT` | `AI_OPS` |
|
||||
| 编排方式 | `SequentialAgent`: Planner -> Executor -> Gatekeeper -> Verifier -> Composer | `SupervisorAgent`: Planner + Executor |
|
||||
| 自评估 | `rule_evaluation` + `verifier_evaluation` | `aiops_rule_evaluation` |
|
||||
| 答案字段 | Chat 最终答复 | 告警分析报告 |
|
||||
| runId 暴露 | `/api/chat` JSON response | `/api/ai_ops` SSE metadata message |
|
||||
|
||||
## 9. 清理与边界
|
||||
|
||||
- Redis 会话历史用于多轮上下文,不是长期审计记录。
|
||||
- MySQL `diagnosis_run + agent_step + tool_invocation` 是主要可回放来源。
|
||||
- `chat_session.expires_at` 只是目录元数据;Redis 消息历史可独立过期。
|
||||
- `RetrievedDocTracker` 仍是 session 级运行时去重状态,诊断结束后清理。
|
||||
|
||||
## 10. 后续增强
|
||||
|
||||
1. Trace API 增加更结构化的 `self_evaluation` 展示。
|
||||
2. `agent_step` 与 `tool_invocation.step_id` 建立更严格关联。
|
||||
3. 旧 `diagnosis_session` 只读观察期结束后,再评估数据库层面的约束收紧或归档策略。
|
||||
应用在创建当前 Run 前读取同 Session 最近安全发布结果。只允许结构化 PublishedResult 的固定字段进入 PreviousTurn,且执行字节上限;完整历史、失败、Fallback、Tool raw data 和 guard reason 均排除。
