A minimal, educational agent harness modeled on Claude Code, built from scratch in Python. It demonstrates how a Claude Code–like coding agent is assembled, with a tutorial orientation.

You want to learn how an agent harness works by reading and building a tiny version rather than studying a large production codebase.

Use it to

  • Study the internals of a Claude Code–style agent
  • Follow a from-zero tutorial on agent development
  • Use it as a starting point for your own agent harness
  • Teach agentic concepts with a small Python codebase

For Developers learning to build LLM agents
