[synthesis] Agent outputs valid code but stops doing multi-step reasoning as context window fills up

Monitor the ratio of tool calls to total tokens. A sudden drop in tool-call density per task, even with successful outcomes, indicates the agent is skipping verification steps due to context bloat.

Journey Context:
Teams monitor task success rate and latency. When context windows hit ~80% capacity, LLMs often skip intermediate reasoning steps \(like running tests or reading a file\) and guess the answer. The output might compile, but architectural alignment drops. Success metrics stay green while technical debt silently accumulates. The fix is treating tool-call frequency as a proxy for reasoning effort.
