name: ci-fix description: "Fix GitHub Actions CI failures using GitHub CLI (gh): inspect runs/logs, identify root cause, patch workflows/code, rerun jobs, and summarize verification. Use when GitHub Actions CI is failing or needs diagnosis."

CI fix (GitHub Actions)

Goal

• Get CI green quickly with minimal, reviewable diffs.
• Use gh to locate failing runs, inspect logs/artifacts, rerun jobs, and confirm the fix.

Inputs to ask for (if missing)

• Repo (OWNER/REPO) and whether this is a PR or branch build.
• Failing run URL/ID (or PR number / branch name).
• What "green" means (required workflows? allowed flaky reruns?).
• Any constraints (no workflow edits, no permission changes, no force-push, etc.).

Workflow (checklist)

1. Confirm gh context
   • Auth: gh auth status
   • Repo: gh repo view --json nameWithOwner -q .nameWithOwner
   • If needed, add -R OWNER/REPO to all commands.
   • If gh is not installed or not authenticated, tell the user and ask whether to install/authenticate or proceed by pasting logs/run URLs manually.
2. Find the failing run
   • If you have a run URL, extract the run ID: .../actions/runs/<id>.
   • Otherwise:
     • Recent failures: gh run list --limit 20 --status failure
     • Branch failures: gh run list --branch <branch> --limit 20 --status failure
     • Workflow failures: gh run list -w <workflow> --limit 20 --status failure
   • Open in browser: gh run view <id> --web
3. Pull the signal from logs
   • Job/step overview: gh run view <id> --verbose
   • Failed steps only: gh run view <id> --log-failed
   • Full log for a job: gh run view <id> --log --job <job-id>
   • Download artifacts: gh run download <id> -D .artifacts/<id>
4. Identify root cause (prefer the smallest fix)
   • Use references/ci-failure-playbook.md for common patterns and safe fixes.
   • Prefer: deterministic code/config fix > workflow plumbing fix > rerun flake.
5. Implement the fix (minimal diff)
   • Update code/tests/config and/or .github/workflows/*.yml.
   • Keep changes scoped to the failing job/step.
   • If changing triggers/permissions/secrets, call out risk and get explicit confirmation.
6. Verify in GitHub Actions
   • Rerun only failures: gh run rerun <id> --failed
   • Rerun a specific job (note: job databaseId): gh run view <id> --json jobs --jq '.jobs[] | {name,databaseId,conclusion}'
   • Watch until done: gh run watch <id> --compact --exit-status
   • Manually trigger: gh workflow run <workflow> --ref <branch>

Safety notes

• Avoid pull_request_target (and any change that runs untrusted fork code with secrets) unless the user explicitly requests it and understands the security tradeoffs.
• Keep workflow permissions: least-privilege; don’t broaden token access “just to make it pass”.
