[research] Upstream LLM provider updates cause subtle changes in agent reasoning without breaking functionality

Track the ratio of reasoning tokens to completion tokens \(or tool call frequency\) as a leading indicator of behavioral drift.

Journey Context:
LLM providers often update models silently. The agent might still complete the task, but suddenly use 3x more reasoning tokens or start preferring Tool A over Tool B. By monitoring the token type ratios and tool frequency distributions in your observability stack, you catch these silent behavioral shifts before they manifest as cost overruns or latency spikes.
