windows-desktop-control

windows-desktop-control is a skill for Claude Code, Codex from virtengine/bosun. It costs 0 tokens per session (663 once invoked), scanned A, original, Apache-2.0.

A skill for controlling native Windows desktop applications and browser surfaces through the visible computer interface when a more structured integration is unavailable. It can choose between accessibility controls, display-aware interaction, and coordinate-based fallback.

In plain words
What is it for?
Use it for native Windows app automation, screen-based browser interaction, display and window placement, screenshots, and actions that require confirmation before changing or deleting data.
Why use it?
It provides a defined way to inspect and operate Windows interfaces when ordinary browser or application integrations cannot reach the needed controls.

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

windows-desktop-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 2mo 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.

Windows Desktop Control

Use this plugin when the task involves native Windows desktop apps or browser surfaces that do not have a stronger structured integration available.

Operating modes

Pick one of these modes before taking action:

  1. UIA-first mode: preferred for native Windows apps with accessible controls.
  2. Visible-display mode: for quick manual-adjacent automation on the user’s active screen.
  3. Isolated-display mode: for non-interrupting automation on a secondary or virtual display that Windows exposes.
  4. Coordinate-fallback mode: for canvas apps, remote surfaces, or controls that UI Automation cannot reach reliably.

Decision rules

  • Prefer structured browser automation for websites when a browser tool or MCP server already exists.
  • Prefer uia_inspect and uia_invoke for native Windows controls before coordinate clicks.
  • Prefer list_displays and display-aware screenshots before assuming the primary screen is the correct target.
  • Prefer move_window to place apps on a non-user display before interacting when isolation matters.
  • Use screenshots to verify state before and after mutating actions.
  • Ask for human confirmation before destructive actions such as deleting data, closing unsaved work, submitting forms, or sending messages.

Mode patterns

UIA-first mode

  1. Call list_windows and focus_window to target the correct app.
  2. Call uia_inspect to find stable selectors.
  3. Use uia_invoke, type_text, or press_keys.
  4. Capture a screenshot after important mutations.

Isolated-display mode

  1. Call list_displays and choose the non-user display by displayId or displayName.
  2. Launch or find the app with launch_app or list_windows.
  3. Call move_window to place the window on that display. Use fitToDisplay: true when full-display placement is better than a preserved window size.
  4. Use screenshot against that display, then prefer uia_* actions.
  5. If coordinate fallback is required, pass displayRelative: true so coordinates stay local to the isolated display.

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.
