macos-computer-use

macos-computer-use is a skill for Claude Code, Codex from furkangonel/cowrangler. It costs 28 tokens per session (1,159 once invoked), scanned A, original, MIT.

A skill for controlling a Mac in the background through screenshots and accessibility information, which describes interface elements such as buttons and text fields. It can work without taking over the user's cursor, keyboard focus, or current desktop space.

In plain words
What is it for?
Use it to capture an app's screen, click or otherwise act on identified interface elements, and check the result after actions.
Why use it?
It helps an agent interact with Mac applications more reliably than guessing screen coordinates, while the user continues working.

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

macos-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 1mo ago.

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.

macOS Computer Use (arka plan, model bağımsız)

computer_use aracın var ve Mac'i arka planda kontrol ediyor. Yaptığın eylemler kullanıcının imlecini hareket ettirmiyor, klavye odağını çalmıyor, Space'i değiştirmiyor. Kullanıcı editörde yazarken sen başka bir Space'teki Safari'de tıklayabilirsin.

Her tool-capable modelle çalışır — Anthropic'e özgü schema yok.

Standart İş Akışı

Adım 1 — Önce capture.

computer_use(action="capture", mode="som", app="Safari")

Numaralı overlay'lerle ekran görüntüsü + AX ağacı döner:

#1  AXButton 'Geri' @ (12, 80, 28, 28) [Safari]
#2  AXTextField 'Adres ve Arama' @ (80, 80, 900, 32) [Safari]
#7  AXLink 'Giriş Yap' @ (900, 420, 80, 24) [Safari]

Adım 2 — Element index ile tıkla.

computer_use(action="click", element=7)

Koordinatlardan çok daha güvenilir. Her modelle çalışır.

Adım 3 — Doğrula. Durum değiştiren her eylemden sonra tekrar capture al:

computer_use(action="click", element=7, capture_after=True)

Capture Modları

mode Döner En İyi Kullanım
som (varsayılan) Ekran görüntüsü + numaralı overlay + AX index Vision modeller; varsayılan tercih
vision Sade ekran görüntüsü SOM overlay görevi engellediğinde
ax Yalnızca AX ağacı, görüntü yok Metin tabanlı modeller

Aksiyonlar

capture           mode=som|vision|ax   app=…
click             element=N     VEYA   coordinate=[x, y]
double_click      element=N     VEYA   coordinate=[x, y]
right_click       element=N     VEYA   coordinate=[x, y]
scroll            direction=up|down|left|right   amount=3
type              text="…"
key               keys="cmd+s" | "return" | "escape"
wait              seconds=0.5
list_apps
focus_app         app="Safari"  raise_window=false

Tüm aksiyonlar capture_after=True kabul eder. Tüm element hedefli aksiyonlar modifiers=["cmd","shift"] kabul eder.

Arka Plan Kuralları

  1. raise_window=True kullanma — kullanıcı bunu açıkça istemedikçe.
  2. Capture'ı uygulamaya kısıtla (app="Safari") — daha az gürültü.
  3. Space değiştirme — cua-driver, hangi Space'in görünür olduğundan bağımsız olarak her Space'teki elementleri kontrol eder.

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.
