Group of 2 Under the hood
Auto mode now shows a dialog explaining when a session isn't eligible for classifier billing changes, with telemetry to match
What
- Claude Code now shows a new dialog when auto mode's tool-call classifier falls back from the server-side classifier to the local one. It tells you Claude Code is changing auto mode to stop charging for classifier requests, but explains that your current session isn't eligible for that change, so this classifier request is still billed as before.
- The dialog appears when the server-side (third-party) classifier has already been refused earlier in the session and a tool call falls back to the local, billed classifier. You can press Enter to continue (and accept the billed request) or Escape to cancel the tool call, which is recorded with the reason "Cancelled at the classifier billing notice."
- New analytics events were added to track when the server-side classifier fails to return a result and auto mode falls back to local classification, and when this new billing notice is shown or closed.
Why
This makes it clear to users when a specific auto-mode session still incurs classifier billing despite an upcoming change to stop charging for these requests, and gives them the choice to cancel rather than proceed with a billed request they didn't expect.
