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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00078 | $0.02519 |
| Opus 5.5 | $0.00031 | $0.01008 |
| Sonnet 5.5 | $0.00016 | $0.00504 |
| Haiku 4.5 | $0.00008 | $0.00252 |
Grade A, and why
host-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 3d 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

macos-computer-use
Skill "macos-computer-use" from furkangonel/cowrangler, covering macos computer use (arka plan, model bağımsız), standart i̇ş akışı, capture modları, aksiyonlar and arka plan kuralları.
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.
electron-expert
Expert in Electron framework, desktop app development, IPC, and cross-platform packaging. Use when the user mentions desktop, Node.js, cross platform, Windows, macOS, or Linux, or when the task involves Electron Architecture, Process Types, IPC Communication, or App Lifecycle.
cli-anything
Control desktop software (GIMP, Blender, LibreOffice, etc.) through CLI-Anything generated command-line interfaces. Calls real application backends — much more reliable than GUI automation via desktop tools.
desktop-click
Click desktop elements or coordinates. When you need to click buttons/icons in applications, select menu items, or interact with desktop UI. Supports element description, name prefix, or coordinates. For browser webpage elements, use browserclick instead.
desktop-find-element
Find desktop UI elements using UIAutomation (fast, accurate) or vision recognition (fallback). When you need to locate buttons/menus/icons, get element positions before clicking, or verify UI state. For browser webpage elements, use browser tools instead.
