Build a Documentation Generator Agent
Learn how to create a coding assistant that automatically generates documentation from code with the Autohand Code Agent SDK. Available in TypeScript, Python, Java, Go, Swift, and Rust.
In this tutorial, you'll build a documentation generator coding assistant that reads source code, understands its structure, and automatically generates comprehensive documentation. This demonstrates how to use the Agent SDK for documentation maintenance.
- Completed Code Reviewer Agent
- Node.js 16+ (for TypeScript), Python 3.10+ (for Python), Java 11+ (for Java), Go 1.16+ (for Go), Swift 5.5+ (for Swift), or Rust 1.60+ (for Rust)
- SDK installed for your chosen language
- API key from your LLM provider (set as
AUTOHAND_API_KEY)
What You'll Build
A documentation generator coding assistant that:
- Reads source code files
- Identifies functions, classes, and methods
- Generates README.md documentation
- Creates inline code comments
- Generates API documentation in Markdown
- Updates existing documentation
Step 1: Create Sample Code
Create a sample code file to document in your chosen language:
Step 2: Create Documentation Agent
Create an agent with documentation generation capabilities in your chosen language:
Step 3: Generate Documentation
Run the documentation generator agent on your sample code in your chosen language:
Key Concepts
The agent reads and analyzes source code to understand its structure and purpose.
Using WRITE_FILE to create comprehensive README.md and documentation files.
Using EDIT_FILE to add inline documentation comments directly in source code.
Generating API documentation in Markdown format with examples.
Complete Example
Here's the complete example with cleanup:
Real-World Applications
This pattern can be applied to:
- API documentation: Auto-generate API docs from source code
- README maintenance: Keep project READMEs up to date automatically
- Code comments: Add documentation to undocumented code
- Migration guides: Generate documentation for version upgrades
- Onboarding: Create developer onboarding documentation
