gh-fix-ci

name	gh-fix-ci
description	Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions. Use GitHub MCP tools for PR metadata and patch context, and use `gh` for Actions check 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 hybrid by design:

• Use GitHub MCP tools for PR metadata, changed files, and review context.
• Use gh for GitHub Actions checks and logs because the connector does not expose that workflow end to end.
• 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 GitHub MCP tools.
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

• Do not imply that GitHub MCP can replace 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.
