Report #41388

[synthesis] Agent enters infinite loop by calling a tool that returns output triggering the exact same tool call

Implement a global call-stack depth limit for tool calls \(e.g., max 10 sequential calls\) and hash the last 3 tool-call arguments; if a hash matches, break the loop and force a summary.

Journey Context:
Without a call-stack limit, an agent can get stuck in a deterministic loop \(e.g., search -> no results -> broaden search -> too many results -> search -> no results\). LLMs lack an intrinsic sense of 'time passed' or 'iterations completed'. A hard depth limit and cycle detection in the orchestration layer are necessary circuit breakers.
