GitHub Actions Failure Phase Audit
Use this skill to identify which CI/CD phase is burning the most minutes when jobs fail.
What this skill does
- Reads one or more GitHub Actions run JSON exports (
gh run view --json ...)
- Detects the first non-success step per failed/cancelled/timed-out job
- Maps failures to phases:
setup, build, test, lint, deploy, security, other
- Aggregates failures by repo + workflow + phase + failed step
- Ranks hotspots by impacted minutes and failure count
Inputs
Optional:
RUN_GLOB (default: artifacts/github-actions/*.json)
TOP_N (default: 20)
OUTPUT_FORMAT (text or json, default: text)
WARN_MINUTES (default: 20)
CRITICAL_MINUTES (default: 45)
FAIL_ON_CRITICAL (0 or 1, default: 0)
WORKFLOW_MATCH, WORKFLOW_EXCLUDE (regex, optional)
REPO_MATCH, REPO_EXCLUDE (regex, optional)
BRANCH_MATCH, BRANCH_EXCLUDE (regex, optional)
PHASE_MATCH, PHASE_EXCLUDE (regex, optional)
Collect run JSON
gh run view <run-id> --json databaseId,workflowName,headBranch,headSha,url,repository,jobs \
> artifacts/github-actions/run-<run-id>.json
Run
Text report:
RUN_GLOB='artifacts/github-actions/*.json' \
WARN_MINUTES=15 \
CRITICAL_MINUTES=35 \
bash skills/github-actions-failure-phase-audit/scripts/failure-phase-audit.sh
JSON output + fail gate:
RUN_GLOB='artifacts/github-actions/*.json' \
OUTPUT_FORMAT=json \
FAIL_ON_CRITICAL=1 \
bash skills/github-actions-failure-phase-audit/scripts/failure-phase-audit.sh
Phase filtered report:
RUN_GLOB='artifacts/github-actions/*.json' \
PHASE_MATCH='^(test|deploy)$' \
bash skills/github-actions-failure-phase-audit/scripts/failure-phase-audit.sh
Run with bundled fixtures:
RUN_GLOB='skills/github-actions-failure-phase-audit/fixtures/*.json' \
bash skills/github-actions-failure-phase-audit/scripts/failure-phase-audit.sh
Output contract
- Exit
0 in reporting mode
- Exit
1 when FAIL_ON_CRITICAL=1 and critical hotspots exist
- Text output includes totals and ranked phase hotspots
- JSON output includes
summary, hotspots, and critical_hotspots
