name: Global Error Handling description: Implement robust error handling with user-friendly messages, specific exception types, fail-fast validation, centralized error boundaries, and graceful degradation. Use this skill when implementing try-catch blocks, throwing or catching exceptions, creating custom error classes or types, implementing error boundaries or middleware, validating input and checking preconditions, implementing retry logic with exponential backoff, handling external service failures, cleaning up resources in finally blocks, creating user-facing error messages, implementing centralized error handling at API boundaries, or designing systems for graceful degradation. Use across all programming languages when implementing error handling logic in any code file.

When to use this skill

• When implementing try-catch blocks or error handling logic
• When throwing or catching exceptions or errors
• When creating custom error classes, types, or error hierarchies
• When implementing error boundaries, middleware, or centralized error handlers
• When validating input and checking preconditions (fail-fast approach)
• When implementing retry logic with exponential backoff for external services
• When handling failures from external APIs, databases, or third-party services
• When cleaning up resources (file handles, connections, locks) in finally blocks or equivalent
• When creating user-facing error messages that are clear and actionable
• When implementing error handling at API boundaries or controller layers
• When designing systems for graceful degradation when non-critical services fail
• When preventing exposure of technical details or security information in errors
• When working with error handling in any programming language or framework
