Handling Errors

When to use this skill

• Implementing error handling in new features.
• Designing error-resilient APIs and distributed systems.
• Improving application reliability through Circuit Breakers or Graceful Degradation.
• Standardizing error messages and custom exception hierarchies.

Workflow

1. Categorization
   • Determine if the error is Recoverable (e.g., Network Timeout) or Unrecoverable (e.g., OOM).
2. Strategy Selection
   • Choose a pattern: Fail Fast, Retry, Circuit Breaker, or Graceful Degradation.
3. Implementation
   • Use language-specific best practices (Custom Exceptions, Result Types, or Explicit Returns).
4. Verification
   • Validate that errors are logged with context and resources are cleaned up.
