GitHub Actions Debugging

Systematically diagnose and fix GitHub Actions failures. Provide precise fixes, not generic troubleshooting.

For CI failures surfaced on a pull request, apply the github-pr skill.

Get Logs Fast

Always start here. Use gh CLI to fetch failure context before reading workflow files.

# List recent failed runs
gh run list --limit 10 --status failure

# View failed run summary (shows failed jobs/steps — get job IDs from here)
gh run view <run-id>

# Get job ID from PR URL (most common starting point)
gh pr checks <pr-number> --json name,conclusion,detailsUrl
