What's inside
- Skill name
screencapture- Description
- Captures the user's macOS screen, a window, or a region with the built-in `screencapture` CLI, then reads the image so the agent can see what the user sees. Use it when the user asks to check how a native macOS app looks (SwiftUI, AppKit, Electron, Qt, Tk, Java Swing), verify a window rendered correctly after a build or code change, diagnose a visual bug they describe in a desktop app, confirm a menu, dialog, or layout state, or asks "can you see this?" about anything outside a browser, even if they don't say "screenshot". Web pages and web apps belong to a browser automation tool.
