Report #66089

[synthesis] Sudden latency spikes in agent step execution precede hallucinated tool inputs

Set baseline latency profiles per tool/action. If time-to-first-token or total generation time exceeds 2 standard deviations, flag the subsequent output for semantic validation before execution, rather than treating latency purely as a performance metric.

Journey Context:
LLMs hedge when uncertain. This hedging manifests as verbose, meandering outputs which take longer to generate. Ops teams treat latency as a load or infrastructure issue, but in LLMs, it is often a confidence issue. High latency correlates strongly with low confidence and a higher probability of hallucinated parameters. Treating latency as a quality signal catches hallucinations before the tool is even executed.
