Code Generation with Gemini

Generate a {{language}} implementation for {{feature_description}}.

Project context:
- Framework: {{framework}}
- Existing patterns: {{pattern_description}}
- This code will be used in: {{usage_context}}

Requirements:
1. Follow {{framework}} best practices and idioms
2. Include comprehensive error handling with typed errors
3. Add TypeScript types / type hints for all parameters and return values
4. Write the code in a way that's testable (dependency injection where appropriate)
5. Include inline comments ONLY for non-obvious logic

Output format:
- Main implementation file
- Types/interfaces file (if needed)
- One example usage showing how to call this code

Do not include package installation instructions or boilerplate I didn't ask for.
