app-preview-craft skillB
app-preview-craft is agent-read markdown (skill) from imshaikot/app-preview-craft-skill: 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 preview.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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
mdr add imshaikot/app-preview-craft-skill/app-preview-craft@v0.2.3mdr add imshaikot/app-preview-craft-skill/app-preview-craft@sha256:f3ef9a806967691fPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
