Monitoring APIs Skill for Prometheus Readiness Metrics

Instrument a local API with route-level request metrics and separate readiness and liveness checks.

Install in Claude Code

Use your own API and its Prometheus client library. A local Prometheus or Grafana instance is optional.

Get the complete `plugins/api-development/api-monitoring-dashboard/skills/monitoring-apis` directory from the pinned GitHub commit.
Copy it into the target project's `.claude/skills/`. Check `.claude/skills/monitoring-apis/SKILL.md`, start Claude Code at the project root, and call `/monitoring-apis`.

Example task

Before a dependency initializes, make /health return 200 and /ready return 503. Complete startup, request both again, and send two product requests with different IDs.

What to check

Readiness moves to 200 and both product requests contribute to the same route-template metric.

Frequently asked question

Should full request URLs be Prometheus labels?

Use stable route templates. Raw paths and query values can create too many time series or expose private values.
