Scaffold-time observability so a shipped product is not blind in prod from day one — error capture (Sentry), request-id structured logging, and /healthz + /readyz endpoints. stack-baseline pins Sentry but nothing wires it; this is the wiring. Loaded by app-scaffolder (bake into the scaffold), infra-provisioner (prod env + probes), and consumed by l3-support (traces) and devops (deploy gate).

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

# observability-baseline

stack-baseline names Sentry and wires it nowhere — so every shipped product's first
prod incident is invisible, and l3-support triages blind. This skill makes three
things exist at scaffold time. Defaults baked in; no founder question.

## 1. Error capture (Sentry)

- `instrumentation.ts` (Next.js) / SDK init at process start; DSN from `SENTRY_DSN`
  env (never hardcoded).
- CI uploads source maps on release so stack traces are readable (release = git sha).
- Capture unhandled rejections + a global error boundary on the client.

## 2. Request-id structured logging

- A logger that emits **JSON** (not `console.log` prose) with a per-request
  `request_id` (generate at the edge, propagate via header/async-local-storage).
- Levels: error / warn / info / debug — diagnostics go to **stderr**, never mixed
  into user-facing stdout. (Same discipline as the CLI logging gap, DEEPEN d94.)
- One log line per request with: request_id, method, path, status, latency_ms.

## 3. Health endpoints

- `GET /healthz` — liveness (process up). `GET /readyz` — readiness (deps reachable:
  db, cache). Cheap, unauthenticated, no PII.

How to install

The exact contents, by fingerprint
mdr add avelikiy/great_cto/observability-baseline@sha256:916b24904603e218

The line at the top of this page pins the label git:20260628.a0bafcf, 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.
