[synthesis] Agent reasoning depth decreases over time, leading to shallow answers, without any change in prompts or models
Instrument the ratio of Chain-of-Thought \(or internal monologue\) tokens to final output tokens. Alert if this ratio drops significantly.
Journey Context:
If an LLM provider experiences increased latency, agents with strict time-to-first-token SLAs or client-side timeouts will truncate the generation early. If the agent is prompted to 'think step by step and then answer', a timeout might cut off the thinking and force an immediate, unreasoned answer. The answer is generated, so it's not a timeout error, but the quality is degraded because the reasoning step was skipped. This synthesizes network timeout behaviors with LLM autoregressive generation mechanics.
