Agent Spend Circuit Breaker
A drop-in middleware/gateway that sits between agent frameworks and tool/LLM providers to prevent runaway loops, enforce budgets, and fail safely. It detects repeated tool-call patterns within a few iterations, applies configurable stop conditions (cost, time, retries), and alerts humans instantly with a minimal repro trace.

Agent Spend Circuit Breaker
A drop-in middleware/gateway that sits between agent frameworks and tool/LLM providers to prevent runaway loops, enforce budgets, and fail safely. It detects repeated tool-call patterns within a few iterations, applies configurable stop conditions (cost, time, retries), and alerts humans instantly with a minimal repro trace.
Target customer
Engineering leads / platform engineers running LLM agents in production (support, ops automation) at SMB-to-midmarket SaaS companies using OpenAI/Anthropic + tool calling (CRMs, ticketing, internal APIs).
Problem-solution fit
Teams have real, recurring exposure to unpredictable metered costs and silent failures when agents enter retry loops; post-hoc logs don’t prevent damage. A circuit-breaker layer that enforces hard limits and loop detection reduces financial risk, improves reliability, and provides auditability for incident response.
