Use this skill when implementing chaos engineering practices, designing fault injection experiments, running game days, or improving system resilience. Triggers on chaos engineering, fault injection, Chaos Monkey, Litmus, game days, resilience testing, failure modes, blast radius, and any task requiring controlled failure experimentation.
nginx C module performance optimization and reliability guidelines based on the official nginx development guide. This skill should be used when optimizing nginx C modules for throughput, latency, memory efficiency, and operational resilience. Triggers on tasks involving buffer optimization, connection tuning, shared memory contention, error recovery, timeout strategy, caching implementation, worker process tuning, or logging performance in nginx C modules.
Test application performance, scalability, and resilience. Use when planning load testing, stress testing, or optimizing system performance.
Execute chaos engineering experiments to test system resilience. Use when performing specialized testing. Trigger with phrases like "run chaos tests", "test resilience", or "inject failures".
Client-side WebSocket resilience patterns: backoff with jitter, circuit breakers, heartbeat hysteresis, command acknowledgment, sequence gap detection, and mobile-aware timeouts.
Test application performance, scalability, and resilience. Use when planning load testing, stress testing, or optimizing system performance.
Build and operate modern Node.js applications with strong architecture, dependency hygiene, performance, resilience, observability, and security controls. Use when designing project layout, runtime/module strategy, testing and CI, release workflows, and production operations.
Design and implement integration architectures connecting financial systems — APIs, FIX protocol, ISO 20022, event-driven patterns, batch feeds, idempotency, and resilience. Use when building custodian integration pipelines, implementing FIX connectivity for order routing, designing ISO 20022 or SWIFT migration messaging, building batch file processing for custodian feeds or EOD reconciliation, implementing idempotency for transaction APIs, designing retry or circuit breaker patterns, mapping data between systems with different schemas, or troubleshooting integration failures causing recon breaks. Trigger on: FIX protocol, ISO 20022, custodian feed, batch processing, API design, idempotency, circuit breaker, dead letter queue, data mapping, integration architecture, SWIFT migration, mTLS, file feed, event-driven, message broker.
