retry-fault-tolerance-design

What problem does it solve?

This Skill helps systems recover from transient failures in external dependencies by adding structured retry logic, timeouts, and circuit breaker protections to avoid cascading failures and service degradation.

Core Features & Use Cases

• Exponential backoff with jitter to reduce collision and retry storms during high contention.
• Configurable timeouts and cancellation to bound resource usage for slow or stuck operations.
• Circuit breaker with state transitions to stop calling unhealthy downstream services and allow controlled recovery.
• Error classification and retry hooks to decide when retries are appropriate (HTTP 5xx, network errors, rate limits) versus permanent failures.
• Use case: resilient HTTP client calls to third-party APIs with automatic retries, jittered backoff, timeouts, and a circuit breaker to protect the system during outages.

Quick Start

Call the retry-fault-tolerance-design skill to wrap an external HTTP request with 5 attempts, exponential backoff (minDelayMs 100, maxDelayMs 5000), jitter 0.2, a 3s timeout, and a circuit breaker configured to open after 5 consecutive failures.
