error-handling-patterns

Retry logic for transient errors uses exponential backoff with jitter and circuit breakers to prevent cascading failures. This Skill designs resilient retry mechanisms that automatically halt downstream calls when dependency thresholds are exceeded.

Result types handle expected error outcomes explicitly without control flow interruption, while exceptions suit unexpected failures. This Skill designs strategies to choose between them for explicit, recoverable error management in TypeScript applications.

Typed exception hierarchies in Python differentiate between transient, permanent, user-actionable, and system-actionable errors. This Skill designs structured classification systems to ensure errors are recoverable and debuggable across your API.

Graceful degradation in React error boundaries requires structured error classification to determine recoverable UI states. This Skill designs error handling strategies that integrate structured logging to make boundary failures debuggable.

Inter-service error management combines typed exception hierarchies with circuit breakers and retry patterns for downstream dependencies. This Skill designs comprehensive strategies to ensure microservice communication is explicit and resilient.
