description

Diagnose Crumb routing faults against the F1-F7 fault matrix (adapter spawn fail / subprocess timeout / schema validation / qa.result missing / self-bias risk / infinite loop / env not propagated). Trigger on "왜 멈췄어?", "에러 났어?", "왜 안 돼?", "어디서 막혔어?", "session stuck", "debug", "fault", "이거 왜 이래?", or signs of trouble (no progress, repeated kinds, error events). Read-only. Returns table + suggested actions per detected fault.

/crumb-debug — F1-F7 routing fault diagnosis

When the user reports the session is stuck / broken:

Preferred path — call the crumb_debug MCP tool with {session: "<ulid>"}.

Fallback path — npx tsx src/index.ts debug <session-id>.

If all clear, the report says ✅ No faults detected. Otherwise table of detected F1-F7 with evidence + suggested action.

Explicit slash form: /crumb-debug <session-id>.
