Exactly. We're basically living through the "distributed systems reliability" moment for agents. Traditional infra has circuit breakers, rate limiters, health checks — agents have nothing.

That's what I'm building: treat agent-to-LLM calls like microservice calls. Detect loops, enforce budgets, fail-open if the firewall itself crashes. Same patterns, new domain.

The interesting part is loop detection needs to be semantic, not just frequency-based. Two agents can politely argue in circles without ever triggering a rate limit.
