Claude Desktop Control: Tasks, Permissions, and Review
Claude can control your desktop — moving windows, clicking buttons, reading screens — through computer use. Doing it safely means defining the task tightly, setting clear permissions, and keeping a review step before anything consequential happens.

Claude's computer use capability lets it see your screen, move a cursor, click buttons, type text, and interact with applications the way a person would. In Claude Desktop, this means Claude can assist with tasks that have no API — moving data between applications, filling in forms, operating software with a graphical interface. Tools like fenbs keep the approved task brief and human decisions in a shared record, so the team always sees what Claude is and is not allowed to do on a given machine.
The main design question for any desktop-control workflow is not whether Claude can do the task — often it can — but whether it should do it without review. Desktop control is powerful precisely because it operates at the same level as a person with the keyboard. That means a mistake has the same consequences as a human mistake: a deleted file, a sent message, a changed setting. The safety comes from the task definition, the permissions, and the review step.
What Claude desktop control can do
Claude can interact with anything visible on the screen: type in text fields, click buttons and links, read text from windows, navigate menus, and take screenshots to confirm the result of an action. It does not have keyboard shortcuts for system actions by default; it uses the visible interface.
This makes it useful for tasks that have no API or automation hook: moving data from a spreadsheet into a web form, filling in an application portal, reading and summarizing an on-screen document, or navigating a legacy system that does not support integrations.

Define the task tightly before you start
Write the task in one sentence before you give Claude control of the desktop. Name the application, the specific action, the input, and the expected output. "Open the HR portal, find the expense form for October, fill in the fields from the provided table, and stop before submitting. Wait for me to review." That sentence gives Claude a clear scope and a natural stopping point.
Vague tasks — "take care of the expense report" — leave Claude to decide what "taking care of it" means, including whether to submit it. A tight task definition is not a limitation; it is the mechanism that keeps Claude's action aligned with what you actually want.
Set permissions before the session
Decide which applications Claude is allowed to interact with in this session. If the task is "fill in a form on the HR portal," Claude does not need access to your email client, your file system, or your browser's password manager. Closing applications you do not want it to touch before the session is the simplest permission control.
Write down the approved application list and the actions Claude is permitted to take. This record is useful when reviewing a session after the fact, when handing the workflow to a colleague, or when something unexpected happens and you need to trace what was allowed.
Keep the approved brief and permissions where the team can read them
Write the approved task scope, the permitted applications, and the human review requirements as Decisions and rules in fenbs. Before a desktop-control session, ask a connected AI app to read the project context so it starts from the approved brief. When the approved scope changes — a new application added, a review step removed — update the Decisions and rules. The next session starts from the current version.

Always include a review step for consequential actions
Any action that is hard to undo — submitting a form, sending a message, deleting a file, making a payment — needs a human review step before Claude takes it. Build this into the task definition: "Stop before submitting. Show me the filled form." This is not overcaution; it is the design pattern that makes desktop control usable for real work.
The review step is also where you catch errors that are invisible to Claude: a wrong value in a field, a step that was skipped because the screen loaded differently, or an unexpected state in the application. Claude sees what is on screen, but you know what the correct outcome should look like.
Test in a non-production environment first
If the application has a test or staging environment, use it for the first several runs. Confirm that Claude navigates correctly, fills in the right fields, and stops at the right point before running the same task against live data. Test with inputs you can verify: a known expense amount, a record you can check afterward.
After each test run, record what worked, what did not, and any adjustments to the task definition. This is the log that makes the workflow repeatable. If you hand the workflow to a colleague, they can read the record rather than repeating the testing from scratch.
How to do this with fenbs
- Create a free account and add a project for the desktop-control workflow.
- Write the approved task scope, permitted applications, and review requirements as Decisions and rules.
- Add a task for each step: task definition, permission setup, test run, and go-live.
- After each session, save where you left off: which runs worked, which did not, and what needs a person to confirm.
- When you hand the workflow to a colleague, share the project context so they start from the current approved brief rather than rebuilding it.
