Can it help prevent 'Out of Memory' (OOM) errors?

Yes, it specifically checks for unbounded queue growth and missing backpressure, which are common causes of memory exhaustion in long-running PHP processes.

How does this skill detect reliability risks?

It uses targeted grep patterns and structural analysis to find anti-patterns such as shared static pools, unbounded arrays used as queues, and service calls lacking timeouts or circuit breakers.

What is a cascading failure in PHP applications?

A cascading failure occurs when a failure in one component (like a database or microservice) triggers a chain reaction that causes other components to fail, eventually leading to a total system outage.

What architectural patterns does this skill recommend?

The skill suggests implementing the Bulkhead pattern for resource isolation, Circuit Breakers for service dependencies, and Exponential Backoff with Jitter for retry logic.

セキュリティとテスト

Detects architectural anti-patterns in PHP systems that cause system-wide cascading failures and service instability.

This skill helps developers build resilient PHP applications by scanning codebases for patterns that lead to system-wide collapses. It identifies critical vulnerabilities such as shared resource contention, synchronous call chains without circuit breakers, and 'thundering herd' retry storms. By providing clear severity classifications, blast radius analysis, and actionable fix patterns, it enables teams to implement the Bulkhead pattern, backpressure mechanisms, and exponential backoff to ensure high availability under high-load or failure conditions.
