v1.0.0Audit pull-request and merge-queue GitHub Actions reliability by scoring failure rate, queue latency, and stale-success risk for merge gates.
Installation
GitHub Actions PR Gate Health Audit
Use this skill to detect unreliable pull-request merge gates before they block developers or hide degraded CI health.
What this skill does
- Reads GitHub Actions run JSON exports
- Filters to PR/merge-gate events by default (
pull_request,pull_request_target,merge_group) - Groups by repository + workflow + event
- Scores risk using:
- failure rate
- consecutive current failures
- average queue wait before run start
- days since last successful run
- Flags warning/critical groups via configurable thresholds
- Emits text or JSON output for CI gates and operational dashboards
