Minimalist Agentic Coder in 200 Lines of TypeScript

2025-03-25

A minimalist agentic coder, mycoder-mini, built using Anthropic's Claude 3 LLM, is implemented in just 200 lines of TypeScript. It receives user prompts, generates shell commands via Claude 3, executes them, and iterates until the task is finished. While limited by synchronous execution, lack of browser integration, and a restricted toolset, mycoder-mini clearly demonstrates the core principles of agentic coding, providing a great starting point for learning and exploring more sophisticated systems.
