This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
common-observability from hoangnguyen0403/agent-skills-standard is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Enforce structured JSON logging, OpenTelemetry distributed tracing, and RED metrics across backend services. Use when adding request correlation, setting up tracing spans, defining SLO burn-rate alerts, or instrumenting middleware.
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
# Common Observability Standards ## **Priority: P1 (HIGH)** ## Logging & Tracing - **JSON Logs**: Always emit JSON structured logs. Never plain-text in prod. - **Correlation**: Extract `X-Request-Id` or `traceparent`. Attach to async context. - **Tracing**: Use OpenTelemetry. Propagate W3C `traceparent`. - **Spans**: Name spans like `<HTTP_METHOD> <route>` (`GET /users/:id`). See [implementation examples](references/implementation.md) for structured logger setup with Pino. ## Metrics - **Required**: Request rate, Error rate, Latency histogram (p50/p95/p99), Saturation. - **SLOs**: Alert on SLO burn rates, not raw threshold spikes. ## Instrumentation Workflow 1. Define the operation and route-normalized span name before adding code. 2. Propagate request/trace context across every async or service boundary. 3. Log one structured event with correlation fields; redact secrets and request bodies. 4. Add RED metrics with route-safe labels, then define an SLO and burn-rate alert. 5. Exercise a success and failure path; confirm spans close and IDs join logs to traces. ## Anti-Patterns - **Console.log**: not use in prod; use structured logger (`pino`, `zap`). …

How to install
mdr add hoangnguyen0403/agent-skills-standard/common-observability@sha256:d78c98c65442d39cThe line at the top of this page pins the label git:20260929.bdf124b, 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.
