Group of 2 Under the hood
Auto-mode permission-decision telemetry now includes which root tool surface was in use
What
The tengu_auto_mode_decision telemetry event, covering both the direct tool-call classifier and the sub-agent handoff classifier, now also records a rootToolSurface field. This is threaded through explicitly in function signatures instead of being bundled only inside the tool-permission context, and it is also passed when a workflow-spawned agent finishes in "auto" permission mode.
Why This gives clearer visibility into which tool surface was active when an auto-mode permission decision was made, useful for understanding and debugging auto-mode behavior across both direct and workflow/sub-agent invocations.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.

What effect passing rootToolSurface has on the classifier's decisions is not specified.
