Read this once. It is the whole list. Everything the setup is allowed to do is on this page, in the order it matters, and nothing is hiding in a folder you have to go find.
One new folder in your home directory. That is the entire footprint. It does not touch your existing projects, your desktop, your photos or your footage, and it does not install anything system-wide without asking you separately.
Nothing is downloaded while it runs. Every file it writes is already inside the file you downloaded. Nothing you have is sent anywhere.
This is the work. Being asked to approve each one is what makes the tool feel broken, so these are approved once, here, in advance.
Anything that leaves your machine, rewrites history, or destroys something. These stay a question no matter how many times you say yes, and no setting in the studio turns them off.
These are guards that sit between Claude and your machine and refuse the command outright. They are not instructions it has been asked to follow. They fire whatever posture you are on.
During the setup: nothing. Afterwards, the only thing that goes out is your conversation with Claude, to Anthropic, the same as any other Claude session. Your files go out only when you ask for something that sends them, and that is on the asks-first list above.
Three postures ship with the studio: careful asks about more,
balanced is what you get here, fast asks about less. Say
“change my posture to careful” in the chat, or run
_SYSTEM/scripts/set_posture.sh. The guards in the third box do not
move when you do that. The posture changes how often you are asked. It never
changes whether the seatbelt is fastened.
And if you want it all gone: the uninstaller renames the folder and stops. Nothing you made is deleted.
Got it, take me back to the download
