Risk

Runaway Agent / Reasoning Loop DoS

Description

Agents enter reasoning loops, retry storms, or unbounded tool invocations, exhausting tokens, compute, or downstream API quotas.

Example

An adversarial input drives an agent into a 10,000-call retry loop; or a misconfigured chain causes recursive sub-agent spawning that exhausts the model API quota.

Mitigation
  • Caps on tool calls, sub-agent depth, and tokens
  • loop detection and circuit breakers
  • rate-limit per agent and tenant
  • alert on cost or rate anomalies.
