GitHub Actions Commit Health Audit

Audit GitHub Actions reliability by commit SHA to surface risky commits causing repeated workflow failures across branches.

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

Inputs

Optional:

• 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

bash

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:

bash

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:

bash

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:

bash

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
