A macOS desktop-control guide using the `usecomputer` command-line tool. It can work with the mouse, keyboard, windows, displays, screenshots, and clipboard.

Take screenshots, find windows or displays, click, type, press keys, scroll, drag, and copy or paste while checking the result.

It provides a way to inspect and operate desktop applications when browser or code-based controls are not enough.

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.

Any agent

npx skills add gettalon/talon-plugins --skill computer

Clone the repo

git clone --depth 1 https://github.com/gettalon/talon-plugins

Made for: Claude Code.

Or install talon, the plugin that ships this one along with the rest of its 8 skills, 11 commands.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.01842
Opus 5.5	$0.00016	$0.00737
Sonnet 5.5	$0.00008	$0.00368
Haiku 4.5	$0.00004	$0.00184

Security

Grade A, and why

computer 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.

Origin

This is a copy

94% identical to talon-computer — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
