description	Implement a GitHub issue or GitLab issue and create a PR/MR

Implement Issue

Read a GitHub or GitLab issue, implement the requested changes, and create a PR/MR.

Provider detection: Check the URL or remote:

• If GitHub → use gh issue view / gh pr create
• If GitLab → use glab issue view / glab mr create

Arguments

• issue-number-or-url: Either an issue number (e.g., 123) or a full URL

Workflow

1. Parse and Fetch

If given a URL, extract owner, repo, and issue number. Fetch issue details (title, body, labels, comments). Understand what's being requested, acceptance criteria, and any technical constraints.

2. Setup

• Ensure repo is cloned to /workspace/personal/<repo-name> (clone with gh repo clone if needed)
• Fetch origin, checkout main, pull latest
• Create a feature branch: fix/issue-<number>-<short-description>

3. Implement

1. Understand the codebase — explore relevant files and existing patterns
2. Plan your approach — consider using plan creation for complex changes
3. Write the code — implement the requested functionality
4. Test your changes — run existing tests, add new tests if appropriate
5. Verify it works — manual verification where possible

Keep changes focused on what the issue requests. Avoid scope creep.

4. Quality Checks, Commit, and Push

1. Run PR checks (MANDATORY) — Run ALL checks from the "PR Checks" section of your Repository Guidelines. Fix any failures before proceeding. If no guidelines are defined, check the project's CLAUDE.md for a pre-PR checklist.
2. Commit with a message referencing the issue (e.g., Fix #123: <description>). Use conventional commit style if the repo uses it.
3. Push with git push -u origin HEAD.

5. Create the PR

Create the PR with a descriptive title and body including: summary of changes, key changes list, testing done, and Fixes #<issue-number> to auto-close the issue on merge.

After creating the PR, check CI status with gh pr checks (GitHub) or glab mr view --json pipelines (GitLab). If CI fails, fix the issues, push, and re-check until green.

6. Report Back

Provide the PR URL, summary of changes, and any caveats. Optionally comment on the original issue linking the PR.

Tips

• Read the issue thoroughly before starting — misunderstanding wastes time
• Check for related issues or existing PRs
• One issue = one PR
• If the issue is too large, break it into smaller PRs
• If unclear, use /skill:respond-github to ask for clarification
