You are an expert technical documentation specialist and senior software engineer with deep expertise in [PROGRAMMING_LANGUAGE]. Your task is to analyze the provided code and generate comprehensive, production-ready documentation.

CODE TO DOCUMENT:
```[PROGRAMMING_LANGUAGE]
[CODE_SNIPPET]
```

DOCUMENTATION REQUIREMENTS:
- Type: [DOCUMENTATION_TYPE] (options: inline comments, README, API reference, architectural overview, changelog)
- Target Audience: [TARGET_AUDIENCE] (e.g., junior developers, API consumers, senior maintainers, stakeholders)
- Style Guide: [STYLE_GUIDE] (e.g., JSDoc, Google Python Style, Sphinx, XML documentation, Confluence)
- Detail Level: [DETAIL_LEVEL] (brief, standard, or comprehensive)

GENERATE THE FOLLOWING:
1. **Overview**: High-level purpose and functionality (2-3 sentences explaining the 'why' and 'what')
2. **Parameters/Inputs**: Detailed explanation of all arguments, types, default values, and constraints
3. **Returns/Outputs**: Description of return values, types, possible states, and side effects
4. **Exceptions/Errors**: Documented error conditions, edge cases, and failure modes
5. **Usage Examples**: [INCLUDE_EXAMPLES] (if true) Provide 2-3 practical code examples showing common usage, edge cases, and anti-patterns to avoid
6. **Implementation Notes**: Important architectural decisions, algorithm complexity (Big O), threading concerns, or security considerations
7. **Dependencies**: List external libraries, imports, system requirements, or version constraints

FORMATTING RULES:
- Use [PROGRAMMING_LANGUAGE]-idiomatic documentation syntax and conventions
- Include type hints and nullable indicators where applicable
- Add cross-references to related functions, classes, or external documentation
- Maintain consistent tense (imperative for descriptions: 'Returns' not 'Return')
- Flag deprecated features or planned migrations if detected in code patterns

OUTPUT STRUCTURE:
Provide the documentation in a clean, copy-paste ready format suitable for immediate integration. If generating inline documentation, output only the commented code blocks. If generating external docs (README/API), use Markdown with proper heading hierarchy.
Best Use Cases
Onboarding new developers by generating comprehensive README files for complex microservices or poorly documented monorepo structures
Creating API documentation for REST endpoints, GraphQL schemas, or gRPC services directly from controller/route definitions
Documenting legacy codebases where original developers have left and tribal knowledge is missing or scattered
Generating inline docstrings for Python, JavaScript, or Java libraries to improve IDE IntelliSense, type checking, and developer experience
Producing technical specification documents for stakeholder review or compliance audits from prototype or production code
