GitHub Actions Commit Health Audit

Use this skill to find commits that repeatedly fail CI so teams can prioritize rollback, revert, or targeted fixes.

What this skill does

• Reads GitHub Actions run JSON exports
• Groups runs by repository + commit SHA
• Scores commit risk using failure rate, failed-run volume, and workflow spread
• Flags warning/critical commit hotspots
• Emits text or JSON output for CI checks and triage dashboards

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• MIN_RUNS (default: 2)
• BRANCH_MATCH (regex, optional)
• BRANCH_EXCLUDE (regex, optional)
• WORKFLOW_MATCH (regex, optional)
• WORKFLOW_EXCLUDE (regex, optional)
• REPO_MATCH (regex, optional)
• REPO_EXCLUDE (regex, optional)
• SHA_MATCH (regex, optional)
• SHA_EXCLUDE (regex, optional)
• FAIL_WARN_PERCENT (default: 25)
• FAIL_CRITICAL_PERCENT (default: 50)
• WARN_SCORE (default: 35)
• CRITICAL_SCORE (default: 60)
• FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

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

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
MIN_RUNS=3 \
bash skills/github-actions-commit-health-audit/scripts/commit-health-audit.sh

JSON output with fail gate:

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

Run with bundled fixtures:

RUN_GLOB='skills/github-actions-commit-health-audit/fixtures/*.json' \
bash skills/github-actions-commit-health-audit/scripts/commit-health-audit.sh

Output contract

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