Report #56455

[research] Agents get stuck in infinite tool-calling loops without throwing errors, consuming tokens and stalling the pipeline

Configure telemetry to emit a metric on consecutive identical or semantically similar tool calls, and set an alert to terminate or inject a human-in-the-loop prompt after N=3 consecutive similar actions.

Journey Context:
LLMs can enter thought loops where they repeatedly call the same tool with the same arguments \(or minor variations\) expecting a different result. Standard timeout limits are too coarse; the agent stays active, just unproductive. Observability must track the semantic similarity or exact hash of sequential tool calls to detect and break these loops before token limits are hit.
