Creates marketing visuals for an app from its screenshots and screen recordings: App Store and Google Play screenshot sets, social and Open Graph cards, 2D screen videos, 3D device mockup images and 3D device videos (iPhone, Galaxy, MacBook). Renders locally with headless Chrome, three.js, sharp and ffmpeg; 41 themes, every property configurable, your own .glb device models, plus a studio where the preview is the editor. Use when the user wants app store or play store screenshots, an app…

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-preview-craft — store screenshots, social cards and 3D device videos

Everything this skill makes is a page (`stage/stage.html`) posed by a theme and captured by
headless Chrome: stills are screenshotted and finished by sharp, videos are rendered frame by
frame and piped into ffmpeg. The same page powers the preview studio, so what the user sees
there is exactly what the CLI exports.

## 0. Find the skill, set it up once

**Paths below are relative to the directory holding this `SKILL.md`.** Resolve it once and
prefix commands with it — `$SKILL` means that directory throughout:

```bash
SKILL=/absolute/path/to/app-preview-craft        # the folder with SKILL.md, scripts/, stage/
# not sure where it was installed? (skill folders, then the Claude Code plugin cache)
find ./.claude/skills ./.agents/skills ./.goose/skills ~/.claude/skills ~/.agents/skills \
     ~/.gemini/skills ~/.config/goose/skills ~/.claude/plugins \
     -path '*app-preview-craft*/scripts/cli.mjs' 2>/dev/null | head -1
```

Then check the machine. `--fix` runs `npm install` inside the skill when packages are missing:

```bash
node "$SKILL/scripts/doctor.mjs" --fix
```
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add imshaikot/app-preview-craft-skill/app-preview-craft@sha256:f3ef9a806967691f

The line at the top of this page pins the label v0.2.3, 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.
