Code Simplifier is an official Anthropic plugin for Claude Code that refines recently changed code for clarity and maintainability while preserving functionality. It reduces nesting depth, replaces convoluted logic like nested ternaries with cleaner control flow, and aligns code with standards like ES modules and React best practices. It helps prevent messy AI-generated code from entering pull requests.

What it's for

  • Clean up AI-generated code before opening a pull request
  • Reduce nested conditionals and ternaries into clearer switch statements
  • Refactor modified components and functions to follow standard React and ES module patterns

Features

  • Targets recently modified code automatically or on demand via prompts
  • Reduces nesting depth and eliminates redundant logic
  • Standardizes function declarations and explicit returns
  • Improves variable and function naming conventions
  • Open-source repository hosted on GitHub by Anthropic
