## What it is
Micro Agent is an open-source CLI AI agent that generates unit tests from a natural language prompt and then iterates on code until all tests pass. It is deliberately scoped to a single focused task rather than acting as a full end-to-end coding agent.

## Use cases
- generate code that passes unit tests from a prompt
- fix broken AI-generated code automatically
- write tests first and let AI make them pass
- iterate on a function until test cases succeed
- use Claude, OpenAI, Ollama, or Groq to generate code

## When to choose
- you want a small, focused AI coding agent with deterministic test-based feedback
- you are tired of manually fixing LLM-generated code
- you want test-driven development assisted by AI
- you prefer a CLI tool that works with multiple LLM providers

## When to avoid
- you need an end-to-end agent that installs modules or edits many files
- you need multi-file refactoring or project-wide changes
- your task cannot be expressed as a unit test
