An AI Agent that writes and fixes test-driven code from natural language descriptions.

Micro Agent is an open-source tool developed by Builder.io to address the unreliability of AI-generated code. It uses unit tests as guardrails to ensure the generated code meets specified requirements. The tool constrains the AI to specific tasks, generates unit tests based on user prompts, writes code to pass these tests, and automatically iterates until all tests pass. This approach results in higher-quality, more reliable code compared to typical AI coding tools.
