Design mobile-style HTML pages (iOS / Android) for preview in the Mobile UI Preview panel. Use when the user asks to build a mobile screen, app UI, phone mockup page, or "make this look like a native app". Enforces correct status-bar and bottom safe-area handling so content never hides under the notch/Dynamic Island or the home indicator.
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
# Mobile UI Design Build single-file HTML pages that look like native mobile screens and preview correctly inside the Mobile UI Preview panel (iPhone / Android / iPad device frames). The preview panel renders your HTML **edge to edge** inside the device screen and draws its **own immersive status bar** (clock, signal, wifi, battery) floating on top of your content. It does **not** shrink your content into the safe area for you. That means the two things that go wrong most often are: 1. Content collides with the status bar at the top (title/text sits under the clock and battery). 2. Content collides with the home indicator / gesture bar at the bottom (a fixed CTA button gets cut by the gesture area). This skill exists to prevent both. **Reserve the top and bottom safe areas explicitly; never paint interactive or important content into them.** ## Non-negotiable rules 1. **Viewport meta is required and must be `viewport-fit=cover`:** ```html <meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover" /> ``` 2. **Reserve the top safe area (status bar).** The panel overlays a status bar of roughly: …

How to install
mdr add maomaochong-ai/open-astravia/mobile-ui-design@sha256:d2ef22f042cc9d0bThe line at the top of this page pins the label git:20260722.436e65a, 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.
