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.
