Community Code Simplification Best Practices

Comprehensive code simplification guide for AI agents and LLMs. Contains 45 rules across 8 categories, prioritized by impact from critical (context discovery, behavior preservation) to incremental (language idioms). Each rule includes detailed explanations, real-world examples comparing incorrect vs. correct implementations, and specific impact metrics.

Core Principles

1. Context First: Understand project conventions before making any changes
2. Behavior Preservation: Change how code is written, never what it does
3. Scope Discipline: Focus on recently modified code, keep diffs small
4. Clarity Over Brevity: Explicit, readable code beats clever one-liners

When to Apply

Reference these guidelines when:

• Simplifying or cleaning up recently modified code
• Reducing nesting, complexity, or duplication
• Improving naming and readability
• Applying language-specific idiomatic patterns
• Reviewing code for maintainability issues
