What review-pr does

The skill diffs your current branch against the base one and goes through the changes file by file. It tries main first, then master, and asks if neither exists. Commits come from git log --oneline <base>..HEAD, the whole diff from git diff <base>...HEAD. When the diff is large it drops to a single file: git diff <base>...HEAD -- <file>.

Every changed file gets checked for logic errors, null or undefined access, race conditions, injection, XSS, auth bypass, hardcoded secrets, SSRF, N+1 queries, unbounded loops, memory leaks and swallowed exceptions. Style drift and missing tests for new behaviour or edge cases are flagged too.

The output is a short summary, a list of problems worth fixing before merge, non-blocking suggestions and a verdict. File paths and line numbers are expected, and fixes should be concrete. The skill only holds Bash, Read, Grep and Glob, so it never edits your code — you apply the fixes yourself.

What it helps with

  • scan a branch diff for bugs before merging
  • spot a hardcoded secret or auth bypass in the changes
  • catch N+1 queries and memory leaks in new code
  • check that new functionality comes with tests
  • get a structured verdict on a pull request

Example prompts for the agent

  • Review the current branch against main
  • Check this pull request for bugs and security issues
  • Look at the diff for src/api/users.ts and tell me what to fix before merge

# Pull Request Review

Review the current branch's changes compared to the base branch.

## Steps

1. Determine the base branch:
   - Try `main`, then `master`, then ask
   - Run `git log --oneline <base>..HEAD` to see all commits in this PR
2. Run `git diff <base>...HEAD` to see the full diff
3. For large diffs, review file-by-file using `git diff <base>...HEAD -- <file>`
4. For each changed file, check for:
   - **Bugs**: logic errors, off-by-one, null/undefined access, race conditions
   - **Security**: injection, XSS, auth bypass, hardcoded secrets, SSRF
   - **Performance**: N+1 queries, unbounded loops, missing indexes, memory leaks
   - **Error handling**: missing try/catch, swallowed errors, unclear error messages
   - **Style**: inconsistency with the rest of the codebase
   - **Tests**: missing tests for new functionality or edge cases
5. Provide a structured review:

   **Summary** — What the PR does (1-2 sentences)

   **Issues** — Bugs, security, or correctness problems that should be fixed before merge

   **Suggestions** — Non-blocking improvements worth considering

   **Verdict** — Approve / Request Changes / Needs Discussion

Be specific — reference file paths and line numbers. Suggest concrete fixes, not vague advice.
