Structured Error Response Enforcer

About

This skill ensures that your API endpoints and internal tools consistently return structured JSON errors instead of plain strings or sensitive tracebacks. It enforces a standardized schema including human-readable messages, unique request IDs for debugging, and ISO timestamps. By providing implementation patterns for FastAPI and custom Python exceptions, it helps developers build secure, traceable, and professional-grade backends while preventing the accidental exposure of sensitive system details to end users.

Key Features

• Prevents sensitive data leaks by redacting stack traces and internal tokens
• Provides custom exception classes for Validation and NotFound errors
• Includes global exception handler patterns for FastAPI integration
• 0 GitHub stars
• Enforces a standardized JSON error schema (error, request_id, timestamp, status_code)
• Integrates automatic request tracing using unique UUID generation

Use Cases

• Securing backend applications by masking raw database and system errors
• Building production-grade REST APIs with consistent error reporting
• Implementing request tracing and observability across distributed microservices
