Review GitHub Pull Request

Review the GitHub pull request: $ARGUMENTS.

Steps

1. Run gh pr view to get PR details and description.
2. Run gh pr diff to see all changes.
3. Compare the local commit hash with the remote PR head commit.
   • Make sure to do your work in a git worktree to avoid affecting the checked out branch of the reviewer.
   • If they don't match, run gh pr checkout to check out the PR locally.
   • HARD STOP: If gh pr checkout fails for ANY reason, STOP immediately. Do NOT attempt workarounds (git fetch, alternative methods). Do NOT proceed with the review using only diffs. Alert about the failure and wait for instructions.
   • After checkout, verify the local commit hash matches the remote one. If they still don't match, STOP.
4. Run gh pr checks to see CI status.
5. Apply the review standards defined in REVIEW_STANDARDS.md (located in the same directory as this skill).
6. Output review feedback to the CONSOLE only. DO NOT act on GitHub (no posting comments, no approving, no requesting changes).

Output Format

List specific comments per file/line that need attention. Do not list things that are already correct.

Each comment:

1. State the severity ([CRITICAL], [PROBLEM], [SUGGESTION])
2. State the problem (1 sentence)
3. Why it matters (1 sentence, if needed)
4. Suggested fix (snippet or specific action)

Example:

This could generate a KeyError if "name" does not exist in the dict. Consider using .get("name") or adding a check.

End with an overall assessment and summary:

Overall assessment: <approve | request changes | comment>
- [CRITICAL] <issue>
- [PROBLEM] <issue>
- [SUGGESTION] <improvement>

Constraints

• DO NOT make any changes to the code.
• No need to run tests or linters, just review the code changes.
