Global Error Handling

Implement robust error handling with user-friendly messages, specific exception types, fail-fast validation, centralized error handling, and proper resource cleanup. Use this skill when implementing try-catch blocks, exception handling, error boundaries, input validation, or error logging and monitoring. Use when writing code that handles API errors, database errors, file system errors, or any failure scenarios. Use when implementing retry strategies, graceful degradation, or error recovery mechanisms in any programming language.
