+ShortDescription: Autonomous command-line AI coding assistant that interacts with LLMs to inspect, modify, and manage codebases.
+Description: Optimus is developed by BrightBrainCoder, an independent software studio building agentic AI tooling for developers. Optimus is a terminal-based agentic coding CLI that reads and writes files, executes shell commands, and works on your project autonomously via a large language model — a pair programmer that lives in your terminal.
