What patterns does it look for in caching?

It identifies 'Cache-Aside' patterns that fail to use stale data when the origin service is unavailable, recommending the 'Stale-while-revalidate' approach to keep the application running.

Does this skill help with circuit breakers?

Absolutely. It checks if your circuit breakers have defined fallback logic so that when a circuit opens, the system provides a meaningful response instead of a generic exception.

What does the Fallback Strategy Auditor do?

It scans your PHP codebase for architectural weaknesses where a single service failure could cause a total system crash, suggesting resilient alternatives like cached data or default values.

Can it detect issues in Hexagonal or DDD architectures?

Yes, it is specifically designed for complex architectures, looking for patterns in Infrastructure and Application layers where external dependencies are typically managed.

API Development

Audits PHP applications for missing fallback and graceful degradation strategies to ensure system resilience during service failures.

This skill analyzes PHP codebases to identify critical points of failure when interacting with external services, caches, or feature flags. It detects 'all-or-nothing' execution patterns and recommends implementing resilient patterns like stale-while-revalidate, circuit breaker fallbacks, and default values. By auditing for graceful degradation, it helps developers build robust systems that remain partially functional even when dependencies fail, preventing cascading errors and improving overall system uptime.
