A context-efficient CLI coding agent built by agents
Keen Code is an open-source CLI coding agent designed for developers seeking an efficient, context-aware tool to streamline coding workflows. Built entirely in Go, Keen Code stands out by preserving the full prompt and design trail, enabling transparency and reproducibility. Its innovative use of turn memory allows it to maintain lean multi-turn sessions, minimizing unnecessary context and improving response relevance. Additionally, Keen Code maps MCP servers to lazy-loaded Skills instead of loading large schemas upfront, optimizing performance in multi-MCP environments. This combination of features makes Keen Code highly suitable for developers working on complex projects who need a lightweight, intelligent assistant integrated directly into their command line environment. Its open-source nature also encourages customization and community-driven improvements, making it a compelling choice for those who value transparency and flexibility in AI developer tools.
