SwiftShift screenshots
This skill regenerates the app settings screenshots as clean 843ร670 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:
.agents/skills/screenshots/bin/capture-swiftshift-screenshots.sh
Optional output directory:
.agents/skills/screenshots/bin/capture-swiftshift-screenshots.sh /tmp/swiftshift-screenshots
What the script does
- Saves current appearance and wallpaper.
- Builds and runs the local dev app with
make build && make run-app.
- 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.
- Captures the window-only PNG by CoreGraphics window id for rounded-corner/shadow alpha.
- Captures a full-screen image and crops the same window rectangle for the true SwiftUI material tint from the real wallpaper.
- Applies the window-only alpha to the tinted crop and composites that onto
assets/bg-light.jpg.
- Repeats for dark mode with
assets/wallpaper-dark.jpg and assets/bg-dark.jpg.
- 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 843ร670 image. The mouse feature visual is cropped from that final image at 633ร310+125+260.
Override if the design changes:
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.
