Thanks to Claude Code users for contributing incredible feedback! We just shipped more features based on what we’re hearing from you all. See Cat’s thread for details on auto-accept mode, auto-compact for context, and filepath autocomplete.

Three more features for Claude Code today: First, auto-accept mode. Press Shift+Tab to toggle on auto-accept for file edits. This reduces friction while keeping you in the driver’s seat—you can tab in/out of auto-accept mode anytime.

We auto-compact for you when using the SDK, so you don't need to. To grab stats yourself, read assistant_message.usage.
