Claude Code v2.1.242

Chrome navigation classifier for auto mode moved to remote config

You'll notice
Useful3 Signal3
Browser Control

An env var for the Chrome navigation classifier is gone; a server setting now controls it.

What

The env variable CLAUDE_PREVIEW_CLASSIFIER_FLOOR is gone. The classifier that decides Chrome navigation in auto mode is now switched by chromeNavigationClassifierEnabled, read from a server-supplied auto-mode config and requiring an exact boolean true.

Details
  • The config object falls back to empty, so with no server value the classifier stays off.
  • Nothing in this build sets the key locally; it is decided by server configuration.
Evidence

chromeNavigationClassifierEnabled

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
