gh-modify-pr

Modify code based on GitHub PR review comments and create a local commit using gh + git. Use when the user asks to "follow PR comments", "fix review comments", "update this PR", or provides a PR URL and asks for edits/commit.

Use this workflow for PR-comment-driven changes.

Inputs

• PR URL (preferred), e.g. https://github.com/owner/repo/pull/123
• Optional scope from user (e.g. only one comment, all unresolved comments)

Workflow

1. Parse owner/repo and PR number from URL.
2. Inspect PR summary:
   • gh pr view <url> --json number,title,headRefName,baseRefName,files,reviews,reviewDecision
3. Fetch inline review comments:
   • gh api repos/<owner>/<repo>/pulls/<number>/comments
4. Extract actionable items from comment bodies.
5. Ensure local repo exists in workspace:
   • If missing: git clone [e-mail]:<owner>/<repo>.git
6. Checkout PR branch in local repo:
   • gh pr checkout <number>
7. Open affected files and implement requested changes exactly.
8. Validate changed files quickly (lint/test only if needed or requested).
9. Commit:
   • git add <files>
   • git commit -m "<clear message>"
10. Report back with:

• What changed
• Commit hash
• Branch name

11. Push only if user asks/approves:

• git push

Rules

• Prefer minimal diffs that address reviewer intent directly.
• Do not silently alter unrelated code.
• If a comment is ambiguous, ask one focused clarification question.
• If no local repo exists, clone first instead of failing.
• Include failed attempts in the final operation log when user asks for traceability.
