Report #3796

[gotcha] Why is my agent stuck in an infinite loop of tool calls, draining my API budget?

Implement a hard limit on the number of consecutive tool calls per agent run and a timeout for tool execution; detect cyclical tool call patterns.

Journey Context:
LLMs can get stuck in loops where Tool A returns an error, so the LLM calls Tool A again with the same arguments. Or, a malicious prompt injection tells the LLM to keep calling a tool forever. Without a circuit breaker on the agent loop, this results in massive API costs and resource exhaustion.
