+name: screenshots
+description: Capture and regenerate SwiftShift marketing screenshots for README/website assets. Use when updating light/dark SwiftShift screenshots, especially `www/src/images/screenshot-light.jpg` and `www/src/images/screenshot-dark.jpg`.
+---
+
+# SwiftShift screenshots
+
+This skill regenerates the app settings screenshots as clean 843×670 composites:
+
+- clean background + empty menu bar skeletons live in `assets/bg-light.jpg` and `assets/bg-dark.jpg`
+- real desktop wallpapers live in `assets/wallpaper-light.jpg` and `assets/wallpaper-dark.jpg`
+- fresh Swift Shift Dev settings window is captured from the local build using macOS window capture plus a full-screen tint crop
+- full screenshot outputs default to `www/src/images/screenshot-light.jpg` and `www/src/images/screenshot-dark.jpg`
+- mouse feature crops default to `www/src/images/mouse-light.jpg` and `www/src/images/mouse-dark.jpg`
+- debug step images are written to `.agents/skills/screenshots/debug/`
+
+## Requirements
+
+- macOS
+- `peekaboo` with Screen Recording and Accessibility permissions
+- ImageMagick (`magick`): `brew install imagemagick`
+- `python3` and macOS `screencapture`
+- Xcode command line build works for this repo
+
+## Command
+
+From the repo root:
+
+```bash
+.agents/skills/screenshots/bin/capture-swiftshift-screenshots.sh
+```
+
+Optional output directory:
+
+```bash
+.agents/skills/screenshots/bin/capture-swiftshift-screenshots.sh /tmp/swiftshift-screenshots
+```
+
+## What the script does
+
+1. Saves current appearance and wallpaper.
+2. Builds and runs the local dev app with `make build && make run-app`.
+3. Temporarily switches to light mode, applies `assets/wallpaper-light.jpg` as the real desktop wallpaper, hides other apps, and opens the Swift Shift menu bar window.
+4. Captures the window-only PNG by CoreGraphics window id for rounded-corner/shadow alpha.
+5. Captures a full-screen image and crops the same window rectangle for the true SwiftUI material tint from the real wallpaper.
+6. Applies the window-only alpha to the tinted crop and composites that onto `assets/bg-light.jpg`.
+7. Repeats for dark mode with `assets/wallpaper-dark.jpg` and `assets/bg-dark.jpg`.
+8. Restores the original appearance and wallpaper.
+
+The script intentionally uses clean skeleton backgrounds so the final menu bar contains only the SwiftShift icon, while the app window keeps the real glass tint from the matching wallpaper.
+
+## Layout constants
+
+The app window is placed at `+255+31` in the final 843×670 image. The mouse feature visual is cropped from that final image at `633×310+125+260`.
+
+Override if the design changes:
+
+```bash
+SWIFTSHIFT_SCREENSHOT_X=250 SWIFTSHIFT_SCREENSHOT_Y=31 \
+SWIFTSHIFT_MOUSE_CROP_X=125 SWIFTSHIFT_MOUSE_CROP_Y=260 \
+  .agents/skills/screenshots/bin/capture-swiftshift-screenshots.sh
+```
+
+## Notes
+
+- The script will briefly change the Mac appearance/wallpaper and hide visible apps.
+- If the app UI gets taller/wider, update the background skeletons and placement constants together.
