Under the hood
The tengu_thinking_drop telemetry event now also records whether context was compacted
What
The tengu_thinking_drop telemetry event, which logs when "thinking" blocks (the model's intermediate reasoning content) are stripped from a request, now also records a context_compacted value. This tracks whether the drop happened alongside a context compaction (the process that trims earlier conversation history to save space).
Why
This gives more detail on why thinking blocks get dropped, making it easier to tell whether compaction was a factor in a given case.
