Documentation Generator

Generate documentation for the specified target.

Target: $ARGUMENTS

Parsing Arguments

Parse the arguments to determine:

1. File path: Required - the file or directory to document
2. Type flag: Optional - --type api, --type readme, or --type module
   • api: Generate API documentation (JSDoc, docstrings, etc.)
   • readme: Generate a README file for the module/directory
   • module: Generate module-level documentation
   • Default: Infer from context

Generation Process

For API Documentation (--type api)

1. Read the target file
2. Identify all functions, classes, and exported items
3. Analyze the code to understand:
   • Parameter types and purposes
   • Return values
   • Side effects
   • Error conditions
4. Generate appropriate documentation:
   • JSDoc for JavaScript/TypeScript
   • Docstrings for Python
   • Doc comments for Go/Rust
5. Insert or update documentation in the file

For README Generation (--type readme)

1. Analyze the directory/module structure
2. Identify key files and exports
3. Generate a README with:
   • Title and description
   • Installation instructions (if applicable)
   • Usage examples
   • API overview
   • Configuration options

For Module Documentation (--type module)

1. Read all files in the module
2. Create module-level documentation
3. Document exports and public interface
4. Add usage examples

Documentation Standards

Follow language-specific conventions:

JavaScript/TypeScript

/**
 * Brief description.
 *
 * @param {Type} name - Description
 * @returns {Type} Description
 * @throws {Error} When...
 * @example
 * const result = func(arg);
 */

Python

"""Brief description.

Longer description if needed.

Args:
    param: Description

Returns:
    Description

Raises:
    Error: When...

Example:
    >>> result = func(arg)
"""

Output

• For API docs: Edit the file in place with new documentation
• For README: Create or update README.md in the target directory
• For module docs: Create or update module documentation file

Always show the user what was generated and ask for confirmation before making changes to existing documentation.
