Report #70327

[research] Agent gets stuck repeatedly calling the same tool with the same arguments without making progress

Add a stateful observer that hashes the \(tool\_name, tool\_args\) tuple of the last N steps. If a duplicate hash is detected, break the trace as an action loop failure and trigger a fallback or human-in-the-loop.

Journey Context:
LLMs often get stuck in repetitive loops when a tool returns an unexpected format or an error they do not understand. They just keep trying the same thing. Because the tool calls are technically succeeding \(returning 200 OK\), standard error monitors do not flag it. You need a structural observer that detects cyclical agent behavior.
