[research] Agent gets stuck in a tool-calling loop and burns through tokens without failing

Implement an observability guardrail: set a hard limit on total\_tool\_calls per task and repeated\_tool\_call\_threshold \(e.g., calling the exact same function with the exact same args > 2 times\). Alert and terminate the trace if breached.

Journey Context:
LLMs often get stuck in loops when a tool returns an error they don't understand, or when they lack the context to proceed. They will just keep trying the same thing. Standard timeouts don't catch this if the loop is fast. You need semantic loop detection in your observability layer to kill the run before it drains your budget.
