Circuit Breaker Pattern
A software design pattern borrowed from electrical engineering. When a service or operation fails consecutively beyond a defined threshold, the system automatically switches to degraded fallback logic, preventing resource exhaustion from infinite retries. Widely applied in microservice fault tolerance and AI agent scenarios.
Core Facts
When giving instructions to AI, one should specify both what to do and what not to do, proactively setting boundaries to prevent the model from improvising freely.
The circuit breaker pattern originates from fault-tolerance design in distributed systems, was systematically described by Michael Nygard in "Release It!", and cuts off calls to downstream services by monitoring the number of consecutive failures.

The circuit breaker pattern originates from fault-tolerance design in distributed systems, was systematically described by Michael Nygard in "Release It!", and cuts off calls to downstream services by monitoring the number of consecutive failures.
The Circuit Breaker Pattern is a fault-tolerance design that includes three states—closed, open and half-open; when an external dependency fails continuously up to a threshold, the system trips and directly rejects requests, and its benefits are preventing cascading failures, reducing wasted resources and giving downstream time to recover.
The circuit breaker mechanism proactively disconnects calls to a failing service when the error rate exceeds a threshold, preventing request buildup and cascading timeouts.
Modern large-scale systems typically contain the impact of failures to a local scope through mechanisms such as load balancing, service meshes, and circuit breaker patterns
In distributed system design, the circuit breaker pattern is typically used to detect the health of downstream services and fail fast, while retry backoff strategies are used to avoid placing additional pressure on overloaded services.
Strategies for mitigating retry storms include exponential backoff, adding random jitter, setting retry budgets (e.g., limiting retry requests to no more than 10% of total requests), and the circuit breaker pattern.
