Error Handling Patterns

Build resilient applications with robust error handling strategies that gracefully handle failures and provide excellent debugging experiences.

When to Use This Skill

• Implementing error handling in new features
• Designing error-resilient APIs
• Debugging production issues
• Implementing retry/circuit breaker patterns
• Handling async/concurrent errors

Workflow

1. Categorize: Is it recoverable (network timeout) or unrecoverable (null pointer, corrupt memory)?
2. Define Strategy: Exception hierarchy vs Result types?
3. Implement: Use try/catch contexts, retry logic, or circuit breakers.
4. Recover: Graceful degradation, fallback values, cleanup.
