Screen Sniper (Tauri + Svelte 5)

Screen Sniper is a macOS screenshot toolbar MVP with:

• Floating toolbar actions
• Screenshot capture modes (area/window/fullscreen)
• Annotation editor (text/arrow/rect/blur + undo/redo)
• Export (clipboard/file/share)
• Local history and custom actions
• OpenAI helper (prompt optimize + image-to-text)
• Local-only storage + OpenAI key in macOS Keychain

Tech Stack

• Tauri 2 + Rust backend (/src-tauri)
• Svelte 5 + TypeScript frontend (/src)
• shadcn-style UI component structure (/src/lib/components/ui)
• Lucide icons via lucide-svelte

Requirements

• Node.js 20+
• Rust toolchain (cargo) installed for Tauri development
• macOS 14+

Commands

• npm install
• npm run check (Svelte/TS diagnostics)
• npm test (unit tests)
• npm run build (frontend build)
• npm run tauri:dev (run desktop app)
• npm run tauri:build (desktop build)

Notes

• Capture relies on macOS screencapture utility.
• OpenAI key is stored using macOS Keychain via Rust keyring crate.
• Hotkeys are loaded from settings and registered through Tauri global shortcuts.
