Liquid Glass macOS app icon made as an Icon Composer file (Icon/AppIcon.icon, JSON plus SVG layers), compiled with actool, and reviewed in every look with ictool. Use when the user wants an app icon, a better icon, or a Dock icon.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# App icon

The icon is an Icon Composer file in git: `Icon/AppIcon.icon`, a folder
with `icon.json` and SVG layers in `Assets/`. You write both by hand.
macOS adds the glass, the highlights, the shadow, the mask, and the dark,
tinted, and clear looks. You never draw those yourself.

- `tools/make_icon.sh` compiles it with `actool` into `Resources/Assets.car`
  and `Resources/AppIcon.icns`. `build.sh` runs it when the icon changed.
- `tools/icon_review.sh` renders it with `ictool` (Icon Composer's command
  line tool, inside Xcode) into one contact sheet you read.

Older app without these files: copy `Icon/`, `tools/make_icon.sh`,
`tools/icon_review.sh`, and `tools/icon_sheet.swift` from the
`new-mac-app` template, the icon block of its `build.sh`, and
`CFBundleIconName` = `AppIcon` from its `Info.plist.in`.

Other cases: [more-cases.md](more-cases.md).
- An Xcode or XcodeGen project (Xcode compiles the `.icon` itself).
- Converting an existing flat icon into layers.
- A Dock icon that changes with a theme or style. `NSApp.applicationIconImage`
  shows a flat picture, so render glass versions ahead of time.

How to install

The exact contents, by fingerprint
mdr add tomcounsell/ai/app-icon@sha256:9077ecc21729e366

The line at the top of this page pins the label git:20261027.b1054fc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
