System Documentation

What problem does it solve?

The Skill provides a standardized error handling framework for Python FastAPI applications, including a hierarchy of domain exceptions, global exception handlers, and safe, structured API responses.

Core Features & Use Cases

  • Typed exception hierarchy: NotFoundException, ValidationException, ConflictException, UnauthorizedException, ForbiddenException, BusinessRuleException.
  • Global exception handlers: Centralized registration to return ApiResponse envelopes and log errors.
  • Structured logging: Integrates with structlog for correlated traces across requests.
  • Retry patterns: Optional integration with tenacity for resilient external calls.
  • Correlation ID support: Middleware to propagate and log correlation IDs.

Quick Start

Register the exception handlers on your FastAPI app to enable consistent error responses.
