Keen Code

Keen Code is an open-source, CLI-based AI coding agent designed for developers who want to work from the terminal. It aims to be minimal — it manages context efficiently and connects to multiple AI providers like Gemini, OpenAI, Anthropic, and DeepSeek, so you're not locked into one model. Keen Code runs as a command-line tool, letting you ask for code suggestions, edits, or reviews directly from your terminal without leaving your workflow.

What sets Keen Code apart is its skill-driven architecture and MCP (Model Context Protocol) support. You can define custom slash commands — like /review or /refactor — that trigger specialized sub-agents with their own instructions. Through MCP, you can connect external tools and data sources, giving the agent real-time access to your project files, documentation, or APIs. The tool comes with six built-in commands: read, write, edit, glob, grep, and bash. It also uses turn memory — compact summaries of previous interactions — to keep context lean and avoid bloating the conversation history.

Keen Code is ideal for software developers and programmers who spend a lot of time in the terminal. It's especially useful for tasks like writing boilerplate code, reviewing pull requests, running security checks, or refactoring large codebases. Since it's open source, you can inspect and customize it to fit your team's workflow. If you're looking for a lightweight, offline-friendly AI coding assistant that puts you in control, Keen Code is worth a try.
