crumb-export

name	crumb-export
description	Export a Crumb session transcript to OpenTelemetry GenAI Semantic Conventions (otel-jsonl), Anthropic Console import format (anthropic-trace), or chrome://tracing (chrome-trace). Trigger on "OTel 로 변환", "datadog 으로", "Vertex 로", "trace export", "convert to OTel", "Anthropic Console 에 올려", "chrome tracing", or any request to ship the transcript to an external observability platform. Read-only.

/crumb-export — transcript → standard format

When the user wants to ship a session transcript to an external observability platform:

Preferred path — call the crumb_export MCP tool with {session: "<ulid>", format: "otel-jsonl"|"anthropic-trace"|"chrome-trace"}.

Fallback path — npx tsx src/index.ts export <session-id> --format <fmt>.

Default format = otel-jsonl (compatible with Datadog / Vertex / Phoenix / Langfuse / AgentOps). anthropic-trace for Claude Console import. chrome-trace for chrome://tracing (per-actor lane via tid).

Auto-emitted on session end at sessions/<id>/exports/{otel.jsonl, anthropic-trace.json, chrome-trace.json} — this skill is for ad-hoc on-demand exports.

Explicit slash form: /crumb-export <session-id> [format].
