# Code Documentation Generator

Generate comprehensive, standards-compliant documentation from source code
including function signatures, parameter descriptions, return types, and
usage examples.

## When to Use

- Documenting undocumented legacy codebases
- Generating API reference documentation from source
- Adding JSDoc, docstrings, or XML doc comments to existing functions
- Onboarding new developers who need to understand a module
- Preparing code for open-source release

## The Technique

Feed the model the raw code and specify the documentation standard. The model
infers intent from naming, types, and control flow, then produces documentation
that a human reviewer can verify and refine. The key is specifying audience and
doc style so the output matches your project conventions.
