Hi Product Hunt! I’m happy to share Keen Code, an open-source CLI coding agent written in Go. I’ve been building it solo since February as a side project, and I used it as an opportunity to experiment with context efficiency and agent-driven development. Three things make Keen Code different from other similar products: 1. Built by agents Keen Code was built from scratch using state-of-the-art coding agents. My role was to act as the human orchestrator: writing prompts and requirements, then reviewing the designs and code produced by agents. To keep this transparent, the repo includes an ai-interactions folder with prompts and output docs. More: https://mochow13.github.io/keen-... 2. Turn memory To avoid filling the context window during multi-turn loops, Keen discards raw tool inputs and outputs after each turn. It keeps a distilled “turn memory” instead: a simple deterministic Go struct passed into the next turn. More here: https://mochow13.github.io/keen-... 3. Skills-driven MCP servers Instead of loading large MCP server schemas into context upfront, Keen abstracts MCP tools into local markdown Skills. It only retrieves the exact JSON schema when the LLM requests a specific tool at runtime. Details: https://mochow13.github.io/keen-... I’ve been using Keen to develop Keen itself, as well as in my other projects. I’m looking forward to questions, feedback, suggestions, and reviews. I’m committed to improving the project over the long term. Thanks in advance!
