name: Global Error Handling description: Implement loud failures with specific exception types, actionable error messages, centralized boundary handling, and graceful degradation with telemetry. Use this skill when writing try/catch blocks, error handlers, exception classes, logging statements, retry logic, or resource cleanup code. Applies to all error scenarios requiring context preservation for debugging, proper resource hygiene, and post-mortem-ready error capture across the entire application stack.

Global Error Handling

When to use this skill

• When writing try/catch/finally blocks or error handling code in any language or framework
• When defining custom exception classes to differentiate user errors, system failures, and timeouts
• When creating error messages for users (plain language) or operators (structured logs with context)
• When implementing centralized error translation at module or API boundaries
• When adding error logging with correlation IDs, stack traces, request IDs, or payload fingerprints
• When implementing graceful degradation with fallback behavior and telemetry alerts
• When writing retry logic with bounded attempts, jitter, and idempotency checks
• When ensuring resources (connections, files, locks) are released in both success and failure paths
• When capturing enough error context for post-mortems without reproducing crashes
• When letting errors bubble up through layers until meaningful context can be added
• When avoiding silent error swallowing that hides bugs from operators
• When instrumenting error paths to make degraded states visible through monitoring
• When implementing error boundaries in React or similar error containment patterns
