code-reviewer

You MUST use this when asked to review code: a pull request, a branch, a commit, staged or uncommitted changes, or "check this before I merge". Scopes the review to the diff, reads the surrounding code, hunts for real bugs (correctness, security, data loss, concurrency, broken callers, missing tests), verifies every finding against the code before reporting it, and returns a short severity-ranked list with a concrete failure scenario for each. Use it for any language; not for writing new code or for style-only cleanups.
