What this skill tells your AI

The instructions your AI receives, as published by owainlewis/youtube-tutorials in tutorials/pi-coding-agent-guide/resources/04-skills/code-review/SKILL.md and read by ahel’s review.

When reviewing code, follow this process:

Step 1: Understand the Change

Run git diff (or git diff --staged for staged changes) to see what changed. Read the modified files in full to understand the surrounding context.

Step 2: Check for Issues

Review each changed file for:

Correctness

  • Logic errors, off-by-one errors, race conditions
  • Missing null/undefined checks at system boundaries
  • Incorrect error handling (swallowed errors, wrong error types)

Security

  • SQL injection, XSS, command injection
  • Hardcoded secrets or credentials
  • Overly permissive file/network access

Performance

  • N+1 queries, unnecessary loops, large allocations
  • Missing indexes for new database queries
  • Blocking operations in async code

Maintainability

  • Unclear naming, overly complex logic
  • Dead code, unused imports
  • Missing types in TypeScript

Step 3: Report

Format your review as:

  1. Summary: One sentence on what the change does
  2. Issues: Specific problems with file paths and line numbers
  3. Suggestions: Optional improvements (clearly marked as optional)

Be direct. Don't pad with praise. Focus on things that matter.
