What probably matters to youSection of the release
What

When Claude Code runs tools on a remote service, each action goes through a permission check. In auto mode that can include a second check by a safety classifier (a model that judges whether an action is safe to approve). Three changes are behind remote switches that default to off:

  • a second check that timed out is retried, where before it ran only once
  • Claude Code's own check can run ahead of time alongside a hold on the action
  • shell commands that cannot be read clearly are treated as needing a person to approve them, with an exception that involves the settings file

The flag server returned on for this site's account and for the anonymous baseline on all three switches. No reading has been taken under this release yet.

Why

This tunes how actions are approved automatically in cloud sessions. The shell change means an unclear command waits for you instead of being approved without you.
