Generate a complete Xcode app-icon set from a single source image (or create a starter icon if the user has none), sized to Apple's current icon spec for the target platform(s) — iOS/iPadOS, macOS, watchOS, tvOS, visionOS — and place it in the right .xcassets AppIcon set with a correct Contents.json. Use this whenever the user wants to create, generate, resize, replace, or fix an app icon / AppIcon set, mentions icon sizes or "all the icon sizes", gets an Xcode/App Store icon error…
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 Generator > **Conversational language:** talk to the user — questions, summaries, reports — in **the language the user writes in** — unless a `conversational language` is set in the hub `DATA.md` (`$APP_HUB/DATA.md`), which overrides it. This sets the *conversation* language only — content/deliverables follow the app's target locales. Apple needs the app icon at specific pixel sizes per platform, in the right format (square, sRGB PNG; no transparency for the App Store / iOS icon; macOS icons use padding + rounded corners), wired up in an `AppIcon` set inside an asset catalog. Getting any of that wrong is an Xcode build error or an upload rejection. This skill produces the whole set correctly from one good source image, using `sips` (built into macOS) — no extra dependencies. ## Prerequisites - **Tools:** `sips` (built into macOS); `swift` from the Xcode command line tools only for `scripts/make_starter_icon.swift`; Python 3, stdlib only. - **Credentials:** none. - **Hub (`$APP_HUB`):** optional — only the conversational-language default in `DATA.md`. - **Other tracks:** none. ## Workflow ### 1. Get the source image — ask or generate Ask the user which they want: …

How to install
mdr add yybd/app-factory/app-icon-generator@sha256:fc09bc216c8850b8The line at the top of this page pins the label git:20260929.a7fd8b7, 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.
