Report #55045

[synthesis] Agent output quality degrades silently despite stable token counts and zero error rates

Monitor the ratio of semantic intent to token count \(e.g., AST nodes per 1000 tokens or functional calls per prompt\) rather than just success/failure metrics. Alert on token inflation without proportional output complexity.

Journey Context:
Teams usually monitor tool call success rates and exception logs. When an agent degrades, it often compensates by over-explaining, adding boilerplate, or repeating context. Standard dashboards show green because token count \(engagement\) is high and no tools errored. However, the signal-to-noise ratio has dropped. The synthesis here is combining LLM token metrics with AST complexity metrics: a rising token-to-AST ratio is the silent killer of agent efficiency, revealing that the agent is working harder but producing less structural value.
