Codebase Brain is a self-improving AI engineering system powered by Gemini 4 Argon that tackles large-scale codebase migrations and refactoring. It uses agents to understand repositories, coordinate changes across hundreds of files, and automatically validate results through tests. A shared memory stores verified solutions, architectural insights, and failed approaches, allowing future agents to build on previous work instead of starting from scratch. We benchmark performance against agents without shared memory, measuring accuracy, speed, and successful migrations.
