claw0 is an open-source, educational AI agent and gateway harness created by shareAI-lab. Rather than functioning purely as a standalone production coding assistant, it is structured as a progressive implementation guide designed to take developers from a basic LLM API loop to a modular, production-ready AI agent gateway in Python. Under the hood, claw0 breaks down agentic development into 10 self-contained, progressive sections across roughly 7,000 lines of Python. Each section is a runnable standalone file introducing a distinct architectural concept—such as basic agent loops, session state management, and command routing—while retaining backward compatibility with previous steps. Day-to-day use involves executing the Python session scripts, configuring environment keys via a standard `.env` file, and interacting with terminal-based agent sessions. What distinguishes claw0 is its explicit role as a pedagogical reference implementation for the larger OpenClaw agent architecture. Instead of hiding harness mechanics behind prepackaged binaries, claw0 exposes session management mechanisms (including interactive session switching commands like `/switch`), workspace sandboxing, and loop handling in clear Python code. claw0 is released as an open-source repository on GitHub with trilingual documentation (English, Chinese, and Japanese). It requires standard Python dependencies and developer-supplied LLM API credentials.
