Report #85578

[synthesis] Agent quality degrades silently as response token count increases without semantic density

Monitor the ratio of unique n-grams to total tokens \(semantic density\) per step. If token count rises but n-gram uniqueness drops below a threshold, trigger a context window compression or agent restart.

Journey Context:
Teams monitor token usage for cost, not quality. High token counts are often misinterpreted as thoroughness. In reality, LLMs under context pressure or uncertainty start looping or padding with boilerplate. This precedes hallucination or goal abandonment. By tracking semantic density \(e.g., unique trigrams/total tokens\), you catch the model losing its grip before it produces an actual error.
