computer-control

computer-control is a skill for Claude Code, Codex from autohandai/code-cli. It costs 51 tokens per session (966 once invoked), scanned A, original, Apache-2.0.

A computer-control skill for operating one real desktop app or browser window. It can discover the app, click, type, scroll, and check what is visibly shown.

In plain words
What is it for?
It is for opening an application, finding its window, entering or editing text, using controls, and verifying the visible result.
Why use it?
It removes the need to perform those actions by hand when a task must happen in a native app on this computer. It also avoids acting on the wrong window by checking the current state first.

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-control 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Native computer control

Operate one exact local app or window, observe before input, perform the requested action, and verify the visible result from fresh state.

Tool boundary

Use the tools advertised by the autohand-computer-use MCP server. Their names start with mcp__autohand-computer-use__, including app and window discovery, launch, state capture, click, text, key, scroll, and verification tools. Follow each tool's current schema instead of guessing fields.

Older manually configured integrations may advertise the legacy mcp__cua-driver__* or mcp__cua__* prefixes. Use those only when the canonical Autohand tools are absent. In user-facing responses, call the capability Autohand Computer Use and do not present the underlying engine or an MCP tool prefix as a separate product the user must install.

When this instruction is present in the request context, the skill is already active. Do not call skill activate, skill info, or read this file again. If canonical or legacy computer-control tools are advertised, call the relevant app-discovery tool immediately. Do not call tool_search or tools_registry to rediscover them.

If those tools are absent, tell the user that native computer control is unavailable and give the exact repair command:

autohand computer install
autohand computer doctor

Do not silently install, upgrade, change OS permissions, or switch to a different automation route during an app-control request. Do not inspect shell paths, home-directory configuration, running processes, or the web as a substitute for the missing native tools.

Workflow

  1. Discover the requested application with list_apps; launch it only when it is not already running. Reuse a known live process/window instead of repeating discovery.
  2. Resolve the exact live target with list_windows and observe it with get_window_state. Prefer a targeted element query and structured elements; do not request both a full AX tree and its structured duplicate. Keep default observation limits; increase them only when truncation hides the needed target. Use desktop state only for a desktop task.
  3. Act once using a fresh element token and the exact process and window target. Prefer semantic elements over coordinates. If coordinates are necessary, derive them from a fresh screenshot of that same target.
  4. Re-observe or call verify_state after each meaningful action. A successful tool return alone does not prove the user-visible outcome.
  5. Stop when the requested postcondition is visible. End only this run's session when the server offers session lifecycle tools; do not stop a shared driver daemon.

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.
