Implement robust error handling with user-friendly messages, fail-fast validation, specific exception types, and proper resource cleanup across the application. Use this skill when writing try-catch blocks, throwing or catching exceptions, implementing error boundaries, handling API errors, or managing error states in any part of the codebase. Apply this skill when validating inputs early (fail fast), providing clear actionable error messages to users without exposing security details, using specific exception types rather than generic errors, implementing centralized error handling at appropriate boundaries, designing for graceful degradation, implementing retry logic with exponential backoff, or ensuring resources are cleaned up in finally blocks. This skill ensures errors are caught and handled appropriately, user experience remains positive even when errors occur, security is maintained by not leaking sensitive information, and systems continue operating or degrade gracefully when non-critical services fa
