Turn a built-in tool off

Switch off one of Claude's built-in tools for every session in this app.

You want a specific built-in tool unavailable to every Claude session in this app.

1. Open Settings and the Claude tab.
2. Scroll past Output style and Permissions to Tools.
3. Uncheck the tool's own checkbox within its group.
4. The screen saves the change immediately, showing a Saved. line and how many tools are now off.

The change is Claude-only and app-wide. It reaches a session already running only the next time that session spawns a subprocess.

See Built-in tools for what each tool does, and Settings for the Claude tab's other fields.
