Rebuild the look of an app the user likes as a native SwiftUI design kit, by measuring its screenshots (sizes, spacing, type, colors, icons), building its parts, and comparing pixel by pixel until they match. Use when the user names an app whose look they want, shares screenshots of one, or says "make it look like X".

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

# Design from app

Look at an app, measure it, and rebuild its design system in SwiftUI. The
result is a design kit (`design-kit` skill) with the reference app's
numbers, and one reference screen that matches the screenshot.

Guessing gets close. Measuring gets it right. Two scripts do the
measuring, next to this skill:

- `scripts/measure.swift`: sizes, positions, text heights, and colors from
  a screenshot.
- `scripts/compare.swift`: a side-by-side, a diff, and the share of pixels
  that differ.

Run them with `swift "${CLAUDE_SKILL_DIR}/scripts/measure.swift" ...`.
All coordinates are points (pixels / 2 for a Retina capture).

## 1. Get the screenshots

Ask for screenshots, or take them with the `clone` skill. You need:

- The window only, at 2x, no desktop. Save them in `design/reference/`.
- One screen with the most parts on it (a sidebar, a list, a toolbar),
  plus close-ups of menus, dialogs, and dark mode if they matter.
- The window size: `measure.swift info shot.png`.

Check: `info` prints the window size in points, and every screenshot uses
the same scale.

## 2. List the parts

Look at each screenshot and name every distinct part: window chrome,
…

How to install

The exact contents, by fingerprint
mdr add tomcounsell/ai/design-from-app@sha256:d4482a8ae5882726

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.
