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.

/switch. - Isolated workspace structure — Organizes agent-driven actions and code modifications within dedicated workspace folders. - Self-contained execution — Ensures every milestone is encapsulated in single, runnable Python files for rapid inspection and debugging. - Trilingual documentation — Provides co-located documentation and code walkthroughs in English, Simplified Chinese, and Japanese.claw0 is designed for AI engineers and backend developers who want to understand, build, or customize terminal agent harnesses and gateways at the code level. It is not intended for end users seeking an out-of-the-box, closed-source CLI assistant with polished GUI/IDE extensions.
