Agent Description

Micro Agent, developed by BuilderIO, is an AI-powered CLI tool that autonomously generates code and corresponding unit tests based on user prompts, iterating until all tests pass. Leveraging models like GPT-4o or Claude, it ensures high-quality, functional code for specific tasks without the complexity of general-purpose coding agents.

Key Features

• Generates unit tests and code from natural language prompts.
• Iterates up to 10 times (configurable) to ensure test cases pass.
• Supports JavaScript, TypeScript, and Python for flexible development.
• Integrates with Visual Copilot for design-to-code refinement.
• Uses GPT-4o by default, with options for Claude models via API keys.
• Provides CLI configuration for OpenAI/Anthropic keys and model selection.
• Ensures code quality with TSC, lint, and test compliance checks.

Use Cases

• Rapid Prototyping: Generates functional TypeScript functions, like anagram grouping, with tests, cutting development time by 40%, per builder.io.
• Code Refinement: Adjusts Visual Copilot’s Figma-to-code output to pass linting and tests, ensuring pixel-perfect designs for web developers.
• Test-Driven Development: Automates unit test creation and code iteration for Python microservices, enhancing reliability for startups.
• Educational Tools: Assists students in learning coding by generating tested code snippets, as noted in GitHub community feedback.

Differentiation Factors

• Test-driven iteration outshines GitHub Copilot’s suggestion-only model.
• Focused task scope avoids Auto-GPT’s error-prone complexity.
• Open-source accessibility surpasses CodiumAI’s paid features.

Pricing Plans

• Free Open-Source Access: Fully available on GitHub with no direct costs.
• Optional Costs: Users incur API fees for external services (e.g., OpenAI’s GPT-4o at ~$0.03/1,000 input tokens or Anthropic’s Claude).
• Configuration: Requires user-provided API keys for LLMs; no subscription fees. Users should verify API costs via OpenAI or Anthropic, as they vary by usage.
