GitHub Actions Run Gap Audit

Use this skill to detect workflow groups that have gone unexpectedly quiet (stale triggers, broken schedules, disabled automation, branch drift).

What this skill does

• Reads GitHub Actions run JSON exports
• Groups by repository + workflow + branch + event
• Computes historical cadence (median and p90 interval hours)
• Compares latest inactivity gap vs historical cadence
• Scores risk severity (ok, warn, critical)
• Emits text or JSON for CI checks and automation guardrails
