GitHub Actions Recovery Latency Audit

Use this skill to measure how quickly workflows recover after failing, and to detect groups that remain red for too long.

What this skill does

• Reads GitHub Actions run JSON exports
• Groups by repository + workflow + branch + event
• Builds failure incidents (first failing run until next success)
• Reports recovery latency for closed incidents
• Reports unresolved incident count + oldest unresolved age
• Scores severity (ok, warn, critical) for triage and CI gates

Inputs

Optional:

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• MIN_RUNS (default: 4)
• WARN_P95_HOURS (default: 6)
• CRITICAL_P95_HOURS (default: 18)
• WARN_OPEN_HOURS (default: 12)
• CRITICAL_OPEN_HOURS (default: 36)
• WARN_OPEN_INCIDENTS (default: 1)
• CRITICAL_OPEN_INCIDENTS (default: 2)
• NOW_ISO (optional fixed clock for deterministic tests)
• WORKFLOW_MATCH / WORKFLOW_EXCLUDE (regex)
• BRANCH_MATCH / BRANCH_EXCLUDE (regex)
• EVENT_MATCH / EVENT_EXCLUDE (regex)
• REPO_MATCH / REPO_EXCLUDE (regex)
• FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

gh run view <run-id> --json databaseId,workflowName,event,conclusion,headBranch,createdAt,url,repository \
  > artifacts/github-actions/run-<run-id>.json

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
TOP_N=15 \
bash skills/github-actions-recovery-latency-audit/scripts/recovery-latency-audit.sh

JSON + fail gate:

RUN_GLOB='artifacts/github-actions/*.json' \
OUTPUT_FORMAT=json \
FAIL_ON_CRITICAL=1 \
bash skills/github-actions-recovery-latency-audit/scripts/recovery-latency-audit.sh

Run against bundled fixtures:

RUN_GLOB='skills/github-actions-recovery-latency-audit/fixtures/*.json' \
NOW_ISO='2026-03-07T14:00:00Z' \
bash skills/github-actions-recovery-latency-audit/scripts/recovery-latency-audit.sh

Output contract

• Exit 0 in report mode (default)
• Exit 1 when FAIL_ON_CRITICAL=1 and one or more groups are critical
• Text mode prints summary + ranked recovery-risk groups
• JSON mode prints summary + ranked groups + critical groups
