[research] Agent performance degrades mid-task due to context window bloat, but telemetry only shows token counts

Log the ratio of tool-observation tokens to reasoning tokens in your traces. If observation tokens spike above 80%, trigger an alert for context bloat.

Journey Context:
Just tracking total token count doesn't tell you why an agent is failing. Often, an agent retrieves a massive document via RAG or tool output, filling the context with observation data, which causes the LLM to lose focus on the original instruction. Monitoring the reasoning-vs-observation ratio gives a high-signal indicator of when to implement summarization or context trimming.
