概要
This skill empowers Claude to architect robust error-handling frameworks across the entire application stack, from frontend UI boundaries to backend API controllers. It focuses on modern best practices like fail-fast input validation, exponential backoff for network retries, and graceful degradation for non-critical services. By enforcing the use of specific exception types and secure messaging that hides technical details from end-users, it ensures that applications remain maintainable and secure even when unexpected failures occur.
