🔓 Claude Code Unleashed - Deobfuscated v1.0.115

The fully reverse-engineered and deobfuscated source code of Claude Code CLI

Version Status Deobfuscation Architecture

⚠️ Important Notice

This is a reverse-engineered, deobfuscated version of Claude Code CLI v1.0.115.

This repository contains:

  • 🔬 Fully deobfuscated source code extracted from the original webpack bundle
  • 📚 Comprehensive documentation detailing the internal architecture
  • 🗺️ Complete module mapping showing how 50,360 lines were reorganized into readable modules
  • 🏗️ Architectural analysis of the event-driven, streaming-first design

  • Respect Anthropic's intellectual property rights
  • Use this for learning and understanding, not for commercial purposes
  • Comply with all applicable laws and Anthropic's terms of service
  • Understand that this is NOT an official release

🎯 What is This Repository?

This repository contains the complete deobfuscation of Claude Code CLI v1.0.115, transforming:

Original Deobfuscated
50,360 lines of webpack-bundled code 6,409 lines of clean, organized Claude code
Minified, obfuscated variables Meaningful function and variable names
Single massive file 71 organized modules across logical directories
No documentation Comprehensive architectural documentation
Unreadable control flow Clear, understandable program structure

🔍 Deobfuscation Methodology

  1. Static Analysis: Parsed the webpack bundle to identify module boundaries
  2. Variable Recovery: Restored ~10,000+ mangled variable names using contextual analysis
  3. Function Extraction: Identified and separated ~500+ individual functions
  4. Module Reconstruction: Rebuilt the original ES6 module structure
  5. Type Inference: Reconstructed TypeScript-like interfaces from usage patterns
  6. Documentation Generation: Created comprehensive docs from code analysis

🚀 Quick Start

Prerequisites

  • Node.js 18.0.0 or higher
  • npm or yarn package manager
  • Unix-like terminal (macOS, Linux, WSL for Windows)

Installation

# Clone the repository
git clone https://github.com/yourusername/ClaudeCodeUnleashed.git
cd ClaudeCodeUnleashed

# Navigate to the code directory
cd 1.0.115/code

# Install dependencies
npm install

# Make the CLI executable
chmod +x src/main.js

# Optional: Create global symlink
npm link

Authentication

Option 1: OAuth (Claude.ai Account)

# Login with your Claude.ai account
node src/main.js login

# This will open your browser for authentication

Option 2: API Key (Anthropic API)

# Login with Anthropic API key
node src/main.js login --api-key

# Or set environment variable
export ANTHROPIC_API_KEY="sk-ant-api03-..."

Basic Usage

# Start a conversation with default model
node src/main.js

# Use a specific model
node src/main.js -m claude-3-opus-20240229

# Check authentication status
node src/main.js status

# Logout
node src/main.js logout

🏗️ Architecture Highlights

Event-Driven Design

// Everything is event-based
conversationLoop.on('stream:delta', handleDelta);
conversationLoop.on('tool:execute', handleToolExecution);
conversationLoop.on('message:complete', handleComplete);

Streaming-First Approach

  • Server-Sent Events (SSE) for real-time responses
  • WebSocket fallback for bidirectional communication
  • Chunked processing for large outputs

Token Management

  • Max conversation: 200,000 tokens
  • Auto-compaction: Triggers at 150,000 tokens
  • Microcompaction: Preserves context while reducing size

Permission System

  • Granular file access control
  • Allow/deny rules per directory
  • Hook-based permission checks

📚 Documentation

Comprehensive documentation is available in the 1.0.115/docs/ directory:

  • First response: <1s (with warm connection)
  • Token processing: ~1000 tokens/second
  • Memory usage: ~50-100MB baseline
  • Background task limit: Configurable (default 10)

🚧 Known Limitations

Current Status

  • ✅ Core functionality: Fully operational
  • ⚠️ MCP connections: Partially implemented
  • ⚠️ Hook system: Configuration UI incomplete
  • ⚠️ Update system: Not fully extracted
  • ❌ Tests: No test suite recovered

Technical Limitations

  1. Some internal APIs may have subtle differences from original
  2. Error messages might differ from official version
  3. Performance optimizations may be missing
  4. Some edge cases might not be handled identically

🤝 Contributing

While this is primarily a research/educational project, contributions are welcome for:

  1. Documentation improvements: Clarifying explanations, fixing errors
  2. Code organization: Better module structure, cleaner interfaces
  3. Missing features: Identifying and documenting unextracted functionality
  4. Analysis tools: Scripts for further deobfuscation or analysis

Please note:

  • This is NOT intended to be a maintained fork
  • No feature additions beyond what exists in v1.0.115
  • Focus on understanding and documenting, not extending
