Report #79432

[synthesis] API latency spikes cause agent to generate shallow, suboptimal plans that execute successfully but miss edge cases

Decouple planning from execution timing. If API latency exceeds a threshold, cache the current state and force a retry for the planning step rather than accepting the truncated chain-of-thought. Monitor the length of the 'thought' step relative to average.

Journey Context:
When LLM API latency spikes, token generation slows down. Under internal or external timeouts, the model's chain-of-thought is cut short. It skips considering edge cases and jumps to the most obvious tool call. The tool call succeeds. Monitoring sees successful execution and high latency, but misses the causal link: the latency caused the shallow plan. The synthesis of LLM inference dynamics \+ timeout behavior \+ plan complexity metrics shows that latency doesn't just slow agents down; it makes them dumber in a way that looks like successful execution.
