Doc Generator

Generate documentation for the selected code or file. Detect the language and use the appropriate documentation format:

• JavaScript/TypeScript: JSDoc with @param, @returns, @throws, @example
• Python: Google-style docstrings with Args, Returns, Raises, Example sections
• Go: Godoc-style comments starting with the function/type name
• Rust: /// doc comments with # Arguments, # Returns, # Errors, # Examples
• Java/Kotlin: Javadoc with @param, @return, @throws
• Other languages: Use the most common documentation convention

Rules:

• Document the purpose, not the implementation
• Include parameter types and descriptions
• Document return values and possible errors/exceptions
• Add a usage example for non-trivial functions
• For classes/modules, add a top-level description of responsibility
• Keep descriptions concise; one sentence per parameter is enough
• Do not document obvious getters/setters unless they have side effects

Output the documented code, preserving the original implementation.
