event-log-tracing SKILL.md skillA

event-log-tracing from baphuongna/pi-crew is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add baphuongna/pi-crew/event-log-tracing@git:20260911.c97bc57

Pins git:20260911.c97bc57 in mdr.lock. Pin the fingerprint instead.

Structured event logging for worker lifecycle, live agents, crash recovery. When NOT to use: high-level metrics dashboards (use observability-reliability); for runtime state inspection (use runtime-state-reader).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# event-log-tracing

Every pi-crew run writes a persistent event log at `.crew/state/runs/<runId>/events.jsonl`. Events are the primary evidence for understanding what happened — especially when workers crash, agents get stuck, or runs become orphaned.

## Event Format

Every event is a JSON object on one line:

```json
{
  "time": "2026-05-14T10:27:52.000Z",
  "type": "worker.spawned",
  "runId": "team_20260514092752_218fe358085d7115",
  "taskId": "01_explore",
  "message": "Worker spawned: pid 12345",
  "data": { "pid": 12345, "role": "explorer" },
  "metadata": {
    "seq": 42,
    "provenance": "team_runner",
    "fingerprint": "a1b2c3d4e5f6g7h8"
  }
}
```

**Required fields:** `time`, `type`, `runId`
**Optional fields:** `taskId`, `message`, `data`, `metadata`
**Metadata auto-populated:** `seq` (line number), `provenance` (who wrote it), `fingerprint` (for terminal events)

## Event Taxonomy

### Worker Lifecycle Events (from child-pi.ts via onLifecycleEvent callback)

| Event | When | Data |
|---|---|---|
| `worker.spawned` | Child process starts with a PID | `{pid, cwd}` |

How to install

The exact contents, by fingerprint
mdr add baphuongna/pi-crew/event-log-tracing@sha256:c69af39dbce729b7

The line at the top of this page pins the label git:20260911.c97bc57, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
