smol
smol is an extremely compact AI agent implemented in a single Go file. It is designed to be so small that developers can read and understand the entire codebase in an afternoon. The agent supports custom tool calling (including shell execution), prompt caching, and works with cloud LLM APIs while minimizing token usage. It is ideal for developers who want a transparent, easily modifiable foundation for building their own agentic systems.
