--- name: error-handling-patterns description: Master error handling patterns across languages including exceptions, Result types, error propagation, and graceful degradation to build resilient applications. Use when implementing error handling, designing APIs, or improving application reliability. --- # Error Handling Patterns Build resilient applications with robust error handling strategies that gracefully handle failures and provide excellent debugging experiences. ## Use this skill when - 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 ## Do not use this skill when - The task is unrelated to error handling patterns - You need a different domain or tool outside this scope ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. ## Resources - `resources/implementation-playbook.md` for detailed patterns and examples.
