Code Reviewing

A skill that reviews code against quality, security, performance, and maintainability checklists and returns a severity-ranked report.

Security & ReviewBeginner★ 1,122⑂ 397AI score 7/10Last updated: Jul 23, 2026

What it does

  • Walks a four-part checklist: code quality, security, performance, maintainability.
  • Scans for common security issues such as hardcoded secrets, SQL injection, XSS, and missing auth checks.
  • Produces a fixed Markdown report: summary → issues (Critical/Major/Minor with line numbers) → strengths → prioritized recommendations → verdict.
  • Limited to Read, Grep, and Glob, so it reviews read-only and never edits your files.

Who it's for

  • Developers on small teams who review their own pull requests
  • Tech leads who want consistent review comment structure across the team
  • Juniors building a pre-commit self-review habit

Examples

  1. "Review the files changed on this branch" → severity-grouped issue list plus a verdict.
  2. "Check src/auth/login.ts from a security angle" → focuses on secrets, input validation, and authorization.
  3. "Is this function well written?" → feedback on naming, duplication, and single responsibility with concrete fixes.
