Micro Agent is a lightweight, AI-powered tool that simplifies test-driven development by generating and iterating code until all test cases pass. Designed to overcome the challenges of error-prone large language models (LLMs), Micro Agent focuses on delivering reliable results without the chaos of general-purpose coding agents.

Why Micro Agent?

Unlike general-purpose AI coding agents that often compound errors, Micro Agent takes a focused approach:

  • Defines clear test cases to validate code functionality.
  • Iterates on code automatically until tests pass.
  • Avoids complex operations like module installation or multi-file handling to minimize errors.

Key Features

Micro Agent offers unique capabilities for streamlined coding workflows:

  • Interactive mode for step-by-step feedback on code generation.
  • Visual matching mode (experimental) to align code with design outputs.
  • Integration with popular LLMs like OpenAI, Claude, and Ollama.
  • Support for Figma integration via Visual Copilot for design-to-code workflows.

Getting Started

Follow these steps to set up and use Micro Agent:

  • Install Node.js v18 or later.
  • Run `npm install -g @builder.io/micro-agent` to install Micro Agent.
  • Start in interactive mode using `micro-agent` and provide prompts to guide the code generation process.
  • Configure your preferred LLM provider by setting the API key and model using the `micro-agent config` command.

Advanced Usage

Micro Agent provides advanced functionality for tailored workflows:

Configuration and Customization

Micro Agent allows flexible customization via CLI or environment variables:

  • Set maximum iterations using `-m` (default: 10).
  • Override default LLM model with `micro-agent config set MODEL=<model>`.
  • Access a visual interface for settings using `micro-agent config`.

Contributing to Micro Agent

Micro Agent is an open-source project, and contributions are welcome. Check out the `good first issue` label in the GitHub repository for beginner-friendly tasks or refer to the CONTRIBUTING.md guide.

Micro Agent represents a step forward in AI-driven development, combining simplicity and focus to enhance test-driven workflows. Whether you're validating unit tests or aligning designs, Micro Agent is a reliable, targeted tool that transforms how you iterate on code.
