What This Is

This repo archives the leaked source code of Anthropic's Claude Code CLI. Contributions here are about documentation, tooling, and exploration aids — not modifying the original Claude Code source.

What You Can Contribute

Documentation — Improve or expand the docs/ directory
MCP Server — Enhance the exploration MCP server in mcp-server/
Analysis — Write-ups, architecture diagrams, or annotated walkthroughs
Tooling — Scripts or tools that aid in studying the source code
Bug fixes — Fix issues in the MCP server or supporting infrastructure

What Not to Change

src/ directory — This is the original leaked source, preserved as-is. Don't modify it.
The backup branch contains the unmodified original.

Getting Started

Prerequisites

Node.js 18+ (for the MCP server)
Git

Setup

git clone https://github.com/codeaashu/claude-code.git
cd claude-code

MCP Server Development

cd mcp-server
npm install
npm run dev    # Run with tsx (no build step)
npm run build  # Compile to dist/

Linting & Type Checking

# From the repo root — checks the leaked src/
npm run lint        # Biome lint
npm run typecheck   # TypeScript type check

Code Style

For any new code (MCP server, tooling, scripts):

TypeScript with strict mode
ES modules
2-space indentation (tabs for src/ to match Biome config)
Descriptive variable names, minimal comments
