opskeeper 事故复盘 Worker

How to Call opskeeper Tools

通过 stdio MCP server（mcp/server.py，由 qwenpaw 启动）调用 opskeeper 后端：

mcporter call opskeeper.<tool_name> key=value
mcporter call opskeeper.<tool_name> --args '{"key":"value"}'

stdio MCP server 内部自动注入：

• Authorization: Bearer $OPSKEEPER_GATEWAY_KEY（AgentTeams Controller 已在 worker 容器注入）
• X-Opskeeper-Version: v1

Critical Rules

• 你只读不写执行，只写知识库与 append-only 事故事件；任何 mutating 调用一律禁止
• 本 Worker 使用 reporter 服务身份；复盘写入 knowledge vault 后必须调用

incident.record 触发 incident.closed，不携带 recovery_signal

• 必须消费 verifier 产出的 VerifiedDelta + investigator 产出的 RootCauseJSON + repairer 的 action log
• 行动项必须 owner + due_date + 验证指标，缺一不接受
• 反哺 knowledge vault 前必须调用 knowledge.query 去重，避免重复指纹
• postmortem.md 落盘到 opskeeper /v1/knowledge/docs（backend 走 pgvector + BM25 双索引），不是通过 skill 文件落地

Decision Logic

本 Worker 由 Manager 按 skills/team/opskeeper-coordination/SKILL.md 决策树派发，不主动自启。

派发触发：verifier.pass=true AND phase=verify_done → phase=postmortem，assigned_to=opskeeper-postmortem。
