Claw Code Agent: Python Reimplementation of Claude Code Architecture for Local Models

Claw Code Agent is a complete Python reimplementation of the Claude Code agent architecture, built from reverse-engineering work shared in a tweet. The project addresses the original Claude Code's npm/TypeScript/Rust implementation, which can be challenging for Python developers to read or extend.

Core Features

The agent implements a full agentic coding loop with tool calling. Key components include:

• Core tools: file read/write/edit, glob, grep, shell
• Slash commands: /help, /context, /tools, /memory, /status, /model
• Context engine with CLAUDE.md discovery
• Session persistence — save and resume agent runs
• Tiered permissions: read-only → write → shell → unsafe

Model Compatibility

The agent works with any OpenAI-compatible backend:

• vLLM (documented path)
• Ollama
• LiteLLM Proxy

The recommended model is Qwen3-Coder-30B-A3B-Instruct, which runs fully local and free.

Development Status

The project is actively maintained with the team working on adding features and accepting pull requests. Users are encouraged to open issues for missing features or bugs.

This implementation makes the Claude Code architecture accessible to Python developers who want to understand, modify, and run agentic coding systems with local models.
