# Error Handling Patterns

Consistent, robust error handling patterns for production applications.

## When to Activate

- Designing error types or exception hierarchies for a new module or service
- Adding retry logic or circuit breakers for unreliable external dependencies
- Reviewing API endpoints for missing error handling
- Implementing user-facing error messages and feedback
- Debugging cascading failures or silent error swallowing

## Core Principles
