2. Understand the existing codebase patterns before making changes
3. Ask the user for any clarifications before proceeding

Step-by-Step Instructions

2. Identify the target format, schema, or template to follow
3. Generate the output with proper structure and formatting
4. Validate the generated output (syntax check, type check, or dry run)
