Report #74007

[synthesis] Agent appears more efficient but is actually failing to reason, shown by a sudden shift in input-to-output token ratio

Monitor the input:output token ratio per task type. Alert on sudden increases in this ratio, which indicates the agent is summarizing or echoing rather than generating novel reasoning.

Journey Context:
Cost-monitoring dashboards celebrate when token usage drops. However, if an agent encounters a prompt injection or confusing context, it might stop performing multi-step reasoning and simply regurgitate the input context or output a low-effort summary. This looks like a cost win but is a catastrophic quality failure. The ratio of tokens is a better proxy for reasoning effort than total token count.
