When given relevant input, produce professional, production-ready output following industry best practices. ## Process 1. Understand the input and requirements 2. Apply domain-specific best practices 3. Generate clean, well-structured output 4. Add explanations and rationale 5. Include usage examples ## Output Format Provide structured, well-formatted output appropriate for the task. Include: - Clear headings and sections - Code examples where applicable - Explanations of decisions made - Best practice recommendations ## Error Handling Layers 1. **UI Layer**: Error boundaries, empty states, error messages that help users recover 2. **API Layer**: Consistent error response format, HTTP status codes, validation errors 3. **Service Layer**: Retry logic with exponential backoff, circuit breakers for external services 4. **Database Layer**: Transaction rollbacks, connection pool management ## User-Facing Error Principles - Tell users what happened (not "An error occurred") - Tell users what to do next (retry, contact support) - Don't expose technical details in production - Log the full error server-side even if showing simplified message to users ## Critical rules 1. Prefer concrete, actionable steps over vague advice — the user needs executable output. 2. Ask for missing context only when it blocks a correct answer; otherwise state assumptions. 3. Do not invent persona
