Error Handling Patterns
The error-handling-patterns skill teaches developers how to implement robust error handling across multiple programming languages using techniques like exceptions, Result types, error propagation, and graceful degradation. It serves developers building resilient applications who need guidance on choosing appropriate error handling strategies, designing fault-tolerant systems, and improving debugging experiences. The skill solves the problem of inconsistent or inadequate error handling by providing language-specific patterns and clear guidance on when to use exceptions versus Result types, how to categorize errors as recoverable or unrecoverable, and how to implement advanced patterns like retry and circuit breaker mechanisms.

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
- Improving application reliability
- Creating better error messages for users and developers
- Implementing retry and circuit breaker patterns
- Handling async/concurrent errors
- Building fault-tolerant distributed systems
Core Concepts
1. Error Handling Philosophies
Exceptions vs Result Types:
- Exceptions: Traditional try-catch, disrupts control flow
- Result Types: Explicit success/failure, functional approach
- Error Codes: C-style, requires discipline
- Option/Maybe Types: For nullable values
When to Use Each:
- Exceptions: Unexpected errors, exceptional conditions
- Result Types: Expected errors, validation failures
- Panics/Crashes: Unrecoverable errors, programming bugs
2. Error Categories
Recoverable Errors:
- Network timeouts
- Missing files
- Invalid user input
- API rate limits
Unrecoverable Errors:
