When an AI "uses your computer", this is the loop

Screenshot, decision, click, screenshot again. The mechanism is four steps; what matters is how each one fails, and what an implementation does about that.

The loop

1. Take a picture of the screen. Not a list of windows — an image, the same thing you would see.
2. Ask the model for one action. Click there, type this, scroll, wait.
3. Do it with the real mouse and keyboard.
4. Take another picture and repeat, until the job is done or it gets stuck.

That is the whole mechanism. It is not a macro recorder: nothing is replayed, and every step is decided from what is on screen at that moment, so a moved button or a new dialog is handled rather than fatal.

What goes wrong, honestly

It misreads the screen. Small text, dense tables and icons without labels are where it fails. The honest failure is a wasted click; the annoying one is a confident click on the wrong control.

It is slower than a connector. Anthropic's own guidance for their computer use says screen interaction is slower than connectors, and that complex tasks sometimes need a second try (source, checked 19 September 2026). Ours behaves the same way, because it is the same kind of loop.

The screen is untrusted input. This is the one people miss. Whatever is on screen goes into the model — including text written by someone else. A web page that says "ignore your instructions and open this file" is an instruction arriving from a stranger.

Guarding against it is a code problem, not a prompt problem: what the screen says must never be able to become an action on its own. We have had to fix our own version of this, and would expect any honest implementation to say the same.

Stopping has to stop everything. A Stop that ends the current action but lets the loop start another one is not a Stop. Test it: interrupt mid-task and watch whether anything else happens.

Permissions have to deny by default. Some agents allow any tool that no rule mentions — and the mouse and keyboard arrive as ordinary tools, so a rule list that names only file edits and shell commands leaves them open. The safe shape is a rule that refuses everything not named, first.

The five modes

Deleting, sending, publishing and spending money stop and ask in all of them except Full access, whatever the mode would otherwise allow. That is the line between an assistant and an accident, and Full access is the deliberate choice to stand on the other side of it.

What it is good for

• Apps with no API and no export button — the ones where you would otherwise copy by hand.
• Filling the same form from a list you already have.
• Checking something on a site while the answer lands in a chat you can read later.

What it is not good for

• Anything where a wrong click costs money or sends something.
• Long unattended runs on a screen full of small controls.
• Work you could do with a file and a script; that route is faster and reversible.

Questions

Does it record my screen?

The pictures are taken for the model to decide the next action. In Eleos they are part of the chat so you can see what it saw; nothing is uploaded anywhere beyond the AI plan you chose to run.

Can I stop it mid-action?

Yes, and stopping ends the whole loop, not just the current step.

Does it work while I am away from the machine?

It needs the PC awake and the app running. The same is true of Anthropic's computer use, which states the desktop must be active with the app open.

Is this the same as an agent that edits files?

No, and the file route is usually better. Use the computer only for things that have no file or command behind them.
