## Core rule

Never change what the code does, only how it does it.

## Execution Phases

1. **Identify recent changes** — Focus on code modified in the current session unless explicitly told to review a broader scope.
2. **Analyze opportunities** — Look for unnecessary nesting, redundant code and abstractions, unclear names, comments that restate obvious code, and nested ternaries.
3. **Apply project standards** — Follow CLAUDE.md conventions such as ES modules, the function keyword, explicit return types and Props types, choosing clarity over brevity.
4. **Verify and document** — Confirm functionality is unchanged and the code is simpler to maintain, documenting only significant changes that affect understanding.
