name	gh-fix-ci
description	Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions. Use `gh` for PR metadata, patch context, Actions check status, and log inspection before implementing any approved fix.

GitHub Actions CI Fix

Overview

Use this skill when the task is specifically about failing GitHub Actions checks on a pull request. This workflow is CLI-first:

• Use gh for PR metadata, changed files, review context, GitHub Actions checks, and logs.
• Summarize the root cause first, propose a focused fix plan, and implement only after explicit approval.

Prereq: authenticate with GitHub CLI once, then confirm with gh auth status. Repo and workflow scopes are typically required for Actions inspection.

Inputs

• repo: path inside the repo (default .)
• pr: PR number or URL (optional; defaults to current branch PR)
• gh authentication for the repo host

Quick start

• python "<path-to-skill>/scripts/inspect_pr_checks.py" --repo "." --pr "<number-or-url>"
• Add --json if you want machine-friendly output for summarization.

Workflow

1. Verify gh authentication.
   • Run gh auth status in the repo.
   • If unauthenticated, ask the user to run gh auth login (ensuring repo + workflow scopes) before proceeding.
2. Resolve the PR.
   • If the user provides a PR number or URL, use that directly.
   • Otherwise prefer the current branch PR with gh pr view --json number,url.
   • When repo and PR are known, fetch PR metadata and patch context through gh.
3. Inspect failing checks (GitHub Actions only).
   • Preferred: run the bundled script (handles gh field drift and job-log fallbacks):
     • python "<path-to-skill>/scripts/inspect_pr_checks.py" --repo "." --pr "<number-or-url>"
     • Add --json for machine-friendly output.
   • Manual fallback:
     • gh pr checks <pr> --json name,state,bucket,link,startedAt,completedAt,workflow
       • If a field is rejected, rerun with the available fields reported by gh.
     • For each failing check, extract the run id from detailsUrl and run:
       • gh run view <run_id> --json name,workflowName,conclusion,status,url,event,headBranch,headSha
       • gh run view <run_id> --log
     • If the run log says it is still in progress, fetch job logs directly:
       • gh api "/repos/<owner>/<repo>/actions/jobs/<job_id>/logs" > "<path>"
4. Scope non-GitHub Actions checks.
   • If detailsUrl is not a GitHub Actions run, label it as external and only report the URL.
   • Do not attempt Buildkite or other providers; keep the workflow lean.
5. Summarize failures for the user.
   • Provide the failing check name, run URL (if any), and a concise log snippet.
   • Call out missing logs explicitly and do not over-claim certainty.
6. Propose a focused fix plan and wait for approval.
   • Keep the plan tied directly to the failing checks and the observed root cause.
7. Implement after approval.
   • Apply the approved fix locally.
   • Run the most relevant local verification available.
8. Recheck status and summarize residual risk.
   • Suggest re-running the relevant tests and gh pr checks.
   • Report what is still unverified, what may still be flaky, and whether any failing checks were external and therefore not actionable here.

Bundled Resources

scripts/inspect_pr_checks.py

Fetch failing PR checks, pull GitHub Actions logs, and extract a failure snippet. Exits non-zero when failures remain so it can be used in automation.

Usage examples:

• python "<path-to-skill>/scripts/inspect_pr_checks.py" --repo "." --pr "123"
• python "<path-to-skill>/scripts/inspect_pr_checks.py" --repo "." --pr "https://github.com/org/repo/pull/123" --json
• python "<path-to-skill>/scripts/inspect_pr_checks.py" --repo "." --max-lines 200 --context 40

Guardrails

• Use gh for Actions log retrieval.
• Treat non-GitHub Actions providers as report-only unless the user explicitly wants a separate investigation path.
• If the failure is clearly unrelated to the local diff, say so before proposing code changes.
