Report #57432

[synthesis] Agent loops silently without throwing an error or completing the task

Enforce a strict, non-LLM-mediated termination condition \(like a hard step limit or a deterministic state check\) rather than relying on the LLM to decide when to stop.

Journey Context:
Agents often get stuck in loops because the LLM evaluates its own progress and incorrectly concludes it needs to retry a step. Since the tool calls succeed \(return 200 OK or valid output\), no system error is thrown. The agent is 'succeeding' at the tool call, but failing at the task. Relying on the LLM to output a 'finish' action fails because it gets trapped in a local minimum of reasoning. A deterministic circuit breaker is required.
