v1.0.0Audit GitHub merge queue workflow health with failure-rate, queue-latency, and stale-success risk scoring.
Installation
GitHub Actions Merge Queue Health Audit
Use this skill to catch unhealthy merge_group (or pull-request gate) workflows before queue times and failures block merges.
What this skill does
- Reads GitHub Actions run JSON exports
- Focuses on merge queue style events (
merge_groupby default) - Aggregates health by repo/workflow (or repo/workflow/branch)
- Scores risk using failure rate, queue latency, and stale-success age
- Emits
ok/warn/criticalwith optional CI fail gate
