QUICK ANSWER

Claude Code executes local system tools. You can run it in safe mode to block terminal write commands, or authorize specific write/execute actions when prompted.

Permission Architecture

On startup, you can specify safety restriction settings:

  • Safe Mode: Run claude --safe to prevent any commands from modifying local directory files or running shell execution processes without confirmation prompts.
  • Command-level Confirmation: Every time Claude attempts to run a terminal script or edit a file, the CLI prints the proposed diff or command and waits for you to hit y/n.
