Use when the user is designing, prototyping, or rewriting a desktop app that must run on multiple OSes (macOS + Windows + Linux) AND feel indistinguishable from a native app to its users — fast launch, native windowing, native input handling, native materials. Trigger words include "cross-platform desktop", "Electron alternative", "Tauri vs native", "WebView wrapper", "near-native performance", "Raycast architecture", "WebKit/WebView2 quirks", "WKWebView", "system tray app", "global hotkey app", "launcher app". Do NOT trigger this skill for pure web apps, pure mobile apps, or for greenfield projects that have no native-feel requirement.
Browser automation via Chrome DevTools Protocol (CDP). Fetch page content, capture screenshots, extract data, check tabs, navigate, and interact with web applications. Use when user says "check browser", "open URL", "browser tabs", "scrape page", "screenshot", "CDP", "web automation", or needs to verify website state, visually compare UI against design specs, extract data from pages, or monitor web dashboards.
