Concurrency & Distributed Systems Reviewer

About

This skill transforms Claude into a specialized Distributed Systems Engineer to audit code for complex concurrency issues and resilience patterns. It identifies common pitfalls like race conditions, deadlocks, and cascading failures while providing actionable guidance on implementing robust retry policies, circuit breakers, and idempotent handlers. Whether you're building microservices, managing worker queues, or handling distributed transactions, this skill ensures your architecture can handle partial failures gracefully and maintain data consistency under heavy load.

Key Features

• Checks for circuit breakers and graceful fallbacks in external dependencies.
• Detects race conditions and deadlocks in asynchronous and multi-threaded code.
• Verifies idempotency keys and deduplication patterns for distributed processing.
• Analyzes timeout configurations and propagation across service call chains.
• Audits retry strategies for exponential backoff, jitter, and error classification.

Use Cases

• Hardening microservices communication and external API integrations against failure.
• Auditing financial systems or payment processing for transactional integrity and idempotency.
• Optimizing background workers and distributed queue consumers for reliable execution.
