Build production-ready systems with stability patterns: circuit breakers, bulkheads, timeouts, and retry logic. Use when the user mentions "production outage", "circuit breaker", "timeout strategy", "deployment pipeline", or "chaos engineering". Covers capacity planning, health checks, and anti-fragility patterns. For data systems, see ddia-systems. For system architecture, see system-design.
Error handling best practices across languages — error types, recovery strategies, user-facing messages, and logging. Reference when implementing error handling or designing error flows.
Monitor background processes from Claude Code using sentinel files, heartbeat liveness, and subagent polling. Best practices and anti-patterns for autonomous loops that need to kick off work, detect completion/failure/hang/timeout, and resume the main context without wasting tokens. TRIGGERS - monitor background process, sentinel file, heartbeat monitoring, process supervision, agentic loop monitor, background task health, detect hung process, poll for completion, watchdog pattern, process liveness, monitor long-running task, agent poll loop, circuit breaker pattern.
Apply when implementing retry logic, rate limit handling, or resilience patterns in VTEX API integrations. Covers VTEX rate limit headers (X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After), 429 status handling, exponential backoff with jitter, circuit breaker patterns, and request queuing. Use for any VTEX marketplace integration that must gracefully handle API throttling and maintain high availability.
Circuit breaker, retry, and DLQ patterns for .NET using Polly and Brighter. Use when implementing fault tolerance, handling transient failures, configuring retry strategies, or setting up dead letter queues. Includes Polly HttpClient patterns and Brighter message handler resilience.
Use this skill when designing microservice architectures, decomposing monoliths, implementing inter-service communication, or solving distributed data challenges. Triggers on service decomposition, saga pattern, CQRS, event sourcing, API gateway, service mesh, circuit breaker, distributed transactions, and any task requiring microservice design decisions or migration strategies.
Implement web service integrations in B2C Commerce using LocalServiceRegistry. Use when calling external APIs, configuring service credentials in services.xml, handling HTTP requests/responses, or implementing circuit breakers. Covers HTTP, SOAP, FTP, and SFTP services.
Portfolio-level risk controls, drawdown management, exposure limits, and circuit breakers for crypto trading
Intelligent system governor that continuously shadow-tests APIs for performance while enforcing strict financial and security guardrails against runaway costs.
Provides robust error handling strategies and patterns. Use when the user mentions resilience, error handling, fallbacks, or debugging failures.
Multi-backend storage layer with automatic failover between Redis, database, and memory backends. Includes circuit breakers per backend and health-aware routing for high availability.
Client-side WebSocket resilience patterns: backoff with jitter, circuit breakers, heartbeat hysteresis, command acknowledgment, sequence gap detection, and mobile-aware timeouts.
