crumb-explain

description

Explain a Crumb transcript event kind (39+ kinds: qa.result, judge.score, step.judge, user.intervene, handoff.rollback, etc.). Returns category, emitter, parent chain, payload shape, source-of-truth (D1-D6), and wiki spec ref. Trigger on "judge.score 가 뭐야?", "qa.result 는 뭔가요?", "explain <kind>", "이 kind 어디 emit?", "what is the X kind", "어떤 actor 가 emit해?", or any schema-vocabulary question. Read-only. Do NOT trigger for general "what is Crumb" or status questions.

/crumb-explain — 39 kind schema lookup

When the user asks about a transcript event kind:

Preferred path — call the crumb_explain MCP tool with {kind: "<name>"}.

Fallback path — npx tsx src/index.ts explain "<kind>".

For partial matches (e.g., "user" → user.intervene / user.veto / ...), tool returns a did-you-mean list.

Explicit slash form: /crumb-explain <kind>.
