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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.00481 |
| Opus 5.5 | $0.00016 | $0.00192 |
| Sonnet 5.5 | $0.00008 | $0.00096 |
| Haiku 4.5 | $0.00004 | $0.00048 |
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 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.
What it actually says
computer-use (Linux/X11)
Quick Start
list_windows # → @wN list (title, pid, geometry)
screenshot {window:"@w2"} # focus + capture; returns @eN AX targets + PNG
click {ref:"@e3"} # click an element by ref
type_text {text:"hello"} # type at cursor
keypress {keys:["Return"]} # submit
Tools
| name | use |
|---|---|
| list_windows | enumerate visible windows |
| screenshot | focus window, capture PNG, return AX targets @eN |
| click | click @eN/@wN or x,y; supports button, clickCount |
| type_text | type literal text at cursor |
| set_text | replace @eN text/entry value (AT-SPI; falls back to ctrl+a + type) |
| keypress | press keys/chords (Return, ["Ctrl","A"], ["ctrl+l","Return"]) |
| scroll | scroll at ref/coords by scrollY/scrollX pixels |
| computer_actions | run a sequence (≤20) in one call |
Pitfalls
- X11 only. Wayland sessions cannot capture other-app windows or synthesize input.
- Enable AT-SPI:
gsettings set org.gnome.desktop.interface toolkit-accessibility true. - Keystrokes go to whatever currently has focus — call
screenshot {window}first to focus the target. - Mouse cursor physically moves on every click (no stealth pointer).
@eNrefs are scoped to the bridge process and invalidated by the nextscreenshot. Re-screenshot after layout changes.- AX walk capped at depth 12 / 200 elements per app.
- Chrome / Electron expose AT-SPI only when launched with
--force-renderer-accessibility. - LibreOffice needs
SAL_USE_COMMON_ONE_ACCESSIBILITY=1and a real Xorg session (not Xvfb).
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 tak-uukti/linux-computer-use (3 stars, last pushed 5mo ago), licensed MIT. It adds 39 tokens to every session and 481 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
Other skills, from other repositories
computer-use
A set of rules for controlling Windows desktop applications through screen observation and simulated mouse and keyboard actions. It also describes how to find and launch installed applications and verify the results.
web-navigator
A browser-automation routing guide for web tasks. It directs navigation, page inspection, and actions such as clicking or filling forms to the appropriate browser tool.
open-computer-use
Platform-neutral guidance for using Open Computer Use, the open-source Computer Use MCP server and CLI for macOS, Linux, and Windows. Use when an agent needs to install, verify, troubleshoot, configure, or operate Open Computer Use through its native CLI, stdio MCP server, or direct Computer Use tool calls.
macos-harness
Read and operate the apps on this Mac from the shell. Use it when a task needs an app's UI and no API, CLI or purpose-built tool can do it.
tauri-pilot
Inspect, interact with, and test a running Tauri v2 app via CLI. Communicates over Unix socket using JSON-RPC 2.0. Use when testing UI, automating interactions, or debugging a Tauri app.
axstream
Fast deterministic macOS UI automation via replayable macros. Use BEFORE driving any macOS app's UI by hand (clicking/typing via computer-use or screenshots) — if a macro exists, replay finishes the task in seconds with no per-step reasoning; after doing a UI task manually, save it as a macro so the next run is fast.…
