computer-use

A tool for reading and operating desktop application windows through their visible controls, accessibility information, and screenshots.

In plain words
What is it for?
Use it to read or control desktop apps, browser windows, and embedded web pages by clicking, typing, scrolling, dragging, or changing values.
Why use it?
It lets an agent inspect what is open and perform routine interface actions without relying only on terminal commands.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

computer-use scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Computer Use

This file is a discovery stub, not the usage guide. The full, version-matched computer-use reference is served by the orca binary itself — kept out of this file on purpose so it can never drift from the binary that will actually run your commands.

Engage Orca's computer-use surface when a task requires desktop-level access to a visible local app or window, including a native app or an external browser window/webview. Do not use for Orca's embedded browser or page-only browser automation. Use orca-cli for Orca's embedded pages and a page-automation tool such as Playwright or CDP for external pages.

Resolve the CLI for this session

Choose the executable once and reuse it for every later command:

  • If the ORCA_CLI_COMMAND environment variable is set, use its value. Orca exports this for managed WSL sessions.
  • Otherwise, in a dev checkout whose session exposes ORCA_DEV_REPO_ROOT, use orca-dev.
  • Otherwise, on Linux outside an Orca-managed terminal, use orca-ide. Never run bare orca there — outside Orca's terminals it normally resolves to the GNOME Orca screen reader (/usr/bin/orca) and starts speech on the user's machine.
  • Otherwise, use orca.

Below, ORCA is a placeholder for the executable you resolved. Substitute it before running anything; do not create a shell variable or run ORCA literally. This works the same way in POSIX shells, PowerShell, and cmd.exe.

If the selected executable cannot run, report its exact error and stop. Do not fall through to another executable, which could silently target a different Orca build.

Load the full guide before running Orca commands

ORCA skills get computer-use

That prints the complete, version-matched guide for the exact binary that will handle your next commands — listing apps/windows, reading UI, and driving clicks, typing, and other accessibility actions. Read it first, then run the specific command you need.

Don't guess subcommands or flags from memory or from a cached copy of this stub. They change between Orca releases, and this file deliberately no longer lists them. Confirm the app is up with ORCA status --json (start it with ORCA open --json if needed), and prefer --json for agent-driven calls.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

computer-use is a skill published in the GitHub repository stablyai/orca (59,228 stars, last pushed today), licensed MIT. It adds 99 tokens to every session and 795 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
