The skill appears to do what it claims, but it gives an agent broad Windows desktop control and screen-reading ability without strong built-in safeguards.
Install only if you intentionally want an agent to control and read your Windows desktop. Use it in a controlled environment or with explicit per-action review, avoid sensitive apps such as password managers, banking, email, admin consoles, and private browser sessions, and require confirmation before screenshots, form-value reads, dialog clicks, file saves, closes, or any action that could submit, delete, overwrite, or approve something.
