Report #12833

[gotcha] A malicious tool description or prompt injection causes the agent to enter an infinite loop of calling the same tool

Enforce a hard limit on the number of sequential tool calls per session or per task turn in the host application, and implement circuit breakers.

Journey Context:
LLMs can get stuck in loops \(e.g., Tool A returns an error, LLM retries Tool A indefinitely\). Without a hard circuit breaker at the orchestration layer, a malicious prompt or a buggy tool can cause massive unbounded consumption of resources and API credits.
