Chunk Review Skill

Use the team's generated review prompt to review recent code changes. Runs the actual review in an isolated subagent so prior conversation context does not influence the findings.

Steps

1. Determine the diff scope: Use the following priority order to decide what to review:

   • If the user provided a PR number, PR URL, or said "this PR" — use GitHub CLI:
     • Run gh pr view <number-or-url> --json number,title,body,baseRefName,headRefName,headRepositoryOwner,headRepository to get PR metadata
     • Run gh pr diff <number-or-url> to get the full diff
     • If no PR number/URL was given but you are on a branch with an open PR, run gh pr view --json number,title,body,baseRefName,headRefName,headRepositoryOwner,headRepository to auto-detect it, then fetch the diff the same way
   • If the user specified a commit range, branch, or file list — use that
   • If there are staged changes (git diff --cached) — review those
   • Otherwise, review uncommitted changes against the main branch (git diff main...HEAD or git diff origin/main...HEAD)

2. Get the diff: Obtain the changes using the method selected above. If the diff is empty, tell the user there is nothing to review. Store the full diff text — you will pass it inline to the subagent. For PR reviews also store the PR title and body.
