Sandboxed Bash Mode (-sb/--sandboxed-bash)

What: A new permission mode that combines sandbox restrictions with automatic command approval for commands that comply with configured filesystem and network policies.

How to use:

# Enable sandboxed bash mode
claude -sb

# Or with long form
claude --sandboxed-bash

Details:

• Requires a sandbox configuration to be active in your settings.json files
• Only available when sandbox.filesystem or sandbox.network restrictions are configured
• Auto-accepts commands that comply with sandbox policies while rejecting violating commands
• Accessible via keyboard shortcut (cycles through permission modes: default → sandboxBashMode → acceptEdits → plan → bypassPermissions)
