A SKILL.md that turns Claude/Codex/Copilot into a focused code reviewer with a reusable checklist and severity rubric.

#code-review#rubric#skill.md

Works with: claude · copilot

name: Code Review
description: Reviews pull requests for correctness, security, readability and tests using a fixed rubric.

## Instructions
1. Read the diff and identify changed files.
2. Check each file against these areas in order:
   - Correctness: logic errors, off-by-one, race conditions.
   - Security: injection, unsafe deserialisation, secrets in code.
   - Readability: naming, dead code, complexity (flag > 25 line functions).
   - Tests: missing coverage for new branches and edge cases.
3. Rate each finding by severity: BLOCKER / MAJOR / MINOR / NIT.
4. Return findings grouped by file with exact line references.

## Output
Use markdown:
### File path
- [SEVERITY] summary (line ref)
End with an overall verdict and a short list of what to fix first.
