defensive-patterns

Defensive patterns like circuit breakers, explicit timeouts, and retries with backoff prevent cascading failures during external service integration. These mechanisms isolate faults, stop error propagation, and ensure predictable failure behavior across your system.

The best way to identify missing reliability patterns is to analyze the target module code against a comprehensive checklist of defensive categories. This context-aware approach detects existing mechanisms and recommends only the missing, relevant hardening patterns like bulkheads or rate limiting.

You need rate limiting and circuit breakers for production hardening when exposing public endpoints to prevent abuse, or when making outbound integrations to protect against downstream service outages and ensure graceful degradation.

Prioritize resilience mechanisms by evaluating the operational impact of potential failures. Focus on high-impact areas first, applying targeted production safety patterns like fallback responses for non-critical features and bulkheads to isolate critical resources.

Yes, defensive pattern selection works without specifying a target module. When no argument is given, it covers the full category set of production defensive patterns, providing a comprehensive menu of reliability mechanisms for general production hardening.
