Review PR

Review a pull request for bugs, regressions, missing tests, and risky changes.

When explicitly invoked with extra text, treat that text as the PR number or URL. If no PR reference is provided, infer it from the current branch.

Process

1. Preferred execution

   • If subagents are available, use github-dev:pr-reviewer and pass the PR reference.
   • Otherwise follow the manual steps below.

2. Parse PR reference

   • If a PR number or URL is provided, extract owner, repo, and PR number.
   • If not, auto-detect the PR from the current branch with gh pr view --json number,headRefName.

3. Fetch PR data

   • Use gh pr diff <number> for the full diff.
