What it does
A drop-in reverse proxy that catches infinite tool loops and enforces hard spend caps in volatile RAM. Sub-35ms overhead. Zero payload retention. The agent repeats the same database write after an unchanged retry. Requests are checked against hourly and daily account caps before they are sent upstream. The bars below illustrate cap windows, not live account utilization. Performance figures are engineering targets and depend on deployment, network conditions, and request profile. An unhandled SQL error leaves an agent retrying the same tool call at 120 attempts per minute. In this example, the sliding deque recognizes the repeat at attempt three and interrupts the cycle before the remaining…from circuit-breaker-sage.vercel.app

AgentGuard – Auto-kill AI agents before they burn through your budget2025 · github.com · ▲47Your AI agent hits an infinite loop and racks up $2000 in API charges overnight. This happens weekly to AI developers. AgentGuard monitors API calls in real-time and automatically kills your process when it hits your budget limit. How it works: Add 2 lines to any AI project: const agentGuard = require('agent-guard'); await agentGuard.init({ limit: 50 }); // $50 budget // Your existing code runs unchanged const response = await openai.chat.completions.create({...}); // AgentGuard tracks costs automatically When your code hits $50 in API costs, AgentGuard stops…
LoopGain – Stop agent loops with control theory, not max_iterationsJul 2026 · github.com · ▲31An open-source cost controller for AI agent loops — stops a loop when it's actually converged and rolls back before it degrades, instead of running to a fixed max_iterations cap. Real-time loop-gain (Aβ) bands + best-so-far rollback. Adapters for LangGraph, CrewAI, AutoGen, LangChain, OpenAI Agents,
