error-handling-patterns

The circuit breaker pattern prevents cascading failures by blocking requests to failing external APIs. This Skill provides guidance on implementing circuit breakers alongside error aggregation and graceful degradation to ensure application resilience during network failures.

Handling errors in Rust and Go is best achieved using Result types and error codes instead of exceptions. This Skill covers language-specific patterns, helping you implement custom error hierarchies and manage failures explicitly across multiple programming languages.

Error aggregation improves application reliability by collecting multiple errors simultaneously rather than failing on the first. This Skill explains how combining aggregation with graceful degradation allows applications to maintain partial functionality during partial failures.

Standard exception handling in Python and TypeScript is covered extensively for microservices. This Skill demonstrates how to manage invalid inputs, downstream service errors, and network failures gracefully across API endpoints to prevent cascading failures.

Custom error hierarchies are needed when managing complex application states and domain-specific failures. This Skill guides you through creating structured error hierarchies and utilizing Option or Maybe types to improve debugging experiences and application reliability.
