Simplify Code Review

CodingIntermediate

Claude Code's official bundled skill /simplify analyzes changed code with three parallel sub-agents (code-reuse, code-quality, efficiency) and automatically fixes discovered issues. Uses context: fork so each agent runs in an isolated context, ensuring stable operation even on large codebases.

# Simplify Reviewer — Built-in Bundled Skill
## Trigger: /simplify

Claude Code's official bundled skill for automated code review.

### How it works:

1. Detect changed files (git diff or staged changes)

2. Fork 3 parallel review agents (context: fork):
```
Agent 1 — code-reuse:
  - Find duplicated logic across files
  - Suggest shared utilities or abstractions
  - Check for existing helpers that could be reused

Agent 2 — code-quality:
  - Check naming conventions and readability
  - Detect anti-patterns and code smells
  - Verify error handling completeness

Agent 3 — efficiency:
  - Identify unnecessary computations
  - Check for N+1 queries or redundant loops
  - Suggest algorithmic improvements
```

3. Merge findings and auto-fix:
  - Prioritize issues by severity
  - Apply safe fixes automatically
  - Flag risky changes for manual review

How Simplify Code Review Works

Simplify detects changed files via git diff, then uses context: fork to run 3 independent agents (code-reuse, code-quality, efficiency) in parallel. Once each agent completes its analysis, results are merged and safe fixes are applied automatically.
