Observability Engineering

Apply this skill to every deployable Z Platform service.

Structured JSON logs with request ID, tenant ID when authorized, service name, and severity.
Metrics for request count, duration, failures, queue depth, retries, and upstream availability.
Traces across browser proxy, AI gateway, agent jobs, and billing events.
Health and readiness endpoints that do not expose secrets.

Redact credentials, prompts containing secrets, payment data, wallet material, and provider headers.
Do not use tenant identifiers as high-cardinality metric labels.
Propagate a correlation ID across API, event, and audit boundaries.
Define dashboards and alerts before enabling a production workload.
Test failed upstream, timeout, retry, and cancellation paths.

A service is not production-ready until its logs, metrics, traces, health endpoints, and rollback signal are documented.
