A resilience design pattern that stops calls to a failing service or operation after repeated errors, allowing it time to recover before retries resume.
A paper-trading bot's stop-loss self-heal failed on every retry for hours while its health check passed all 55 checks. Each recovery step was correct on its own, and the fault only appeared when the whole chain met the broker's uniqueness rule.
Reality
Retry math in a dev.to post on agent circuit breakers has a failing agent's calls growing from 2,000 tokens to 20,000 by attempt 50. Summed, that spend rises with the square of the attempts, so the cap belongs in the orchestrator.
Reality
A dev.to guide to LLM API retries runs Retry-After through its jitter formula, so a 10-second instruction can yield a 5-second wait. Its retry ladder, 60-second deadline and circuit breaker make a sound default once that one line is fixed.
Reality
Stopping all 15 guarded jobs uniformly cut a posting job to a 43% execution rate, so the guard now lets a job flagged --priority send one real request every 1800 seconds, from a budget every priority job shares.
Reality
A dev.to post wraps an autonomous code-review agent in a CLOSED/OPEN/HALF-OPEN state machine. The constructor's defaults show which of its four blast-radius dimensions an adopter has to wire up alone.
Reality
Wiring the breaker_machines gem into a Rails app took an afternoon. Making a circuit actually open took a week. The decisions that survive are about which Redis database holds state and which integration sets its own threshold.
Reality
One developer's LaunchAgent fleet hit Claude Code's weekly limit and kept firing. His fix is a shared circuit breaker with a state file, not better error handling inside each job.
