GitHub Actions Failure Spike Audit

Use this skill to catch workflows that recently degraded (new flaky tests, broken deploy gates, bad dependency updates, or infra outages) before they become long-running incidents.

What this skill does

• Reads GitHub Actions run JSON exports
• Groups by repository + workflow + branch + event
• Splits each group into recent runs and baseline history
• Compares recent failure rate to baseline failure rate
• Scores severity (ok, warn, critical) using spike + recent failure rate gates
• Emits text or JSON output for CI automation
