Making App Store and Google Play screenshots by hand — opening Figma, hunting for device mockups, double-checking pixel sizes — gets old fast. This skill turns all of that into one request to your coding agent: point it at your raw screenshots (or let it drive your app and capture them itself), answer a few multiple-choice questions, approve the copy, and get a full set of store-ready PNGs.

✨ What it does

• 📱 Device frames — iPhone, iPad, Galaxy, Fold, Flip, drawn in pure CSS (no mockup downloads, no license worries)
• 🎨 Branded backgrounds — extracts your app's real design colors (colors.xml, .xcassets, app icon); Modern/Minimal, Pop, and Dark presets included
• ✍️ Marketing copy — reads each screen and proposes benefit-driven headlines and subcopy, and only proceeds after you approve
• 📐 Exact store sizes — App Store 1320×2868 / 1284×2778, iPad 2064×2752, Google Play 1080×1920, and more — every PNG is pixel-verified
• 🤖 Hands-free capture — no screenshots yet? The agent drives your app itself (adb on Android; deep links, idb, or Maestro on the iOS Simulator) with the status bar unified to 9:41 / 100% battery

On older Codex versions the skills path may be ~/.codex/skills/.

💬 Usage

In Claude Code:

/store-screenshots ./screenshots

In Codex:

$store-screenshots ./screenshots

(or pick it from /skills)

Or just ask in plain language — "make my App Store screenshots".

How a run goes

1. Collect originals — scans your folder for screenshots; if there are none, the agent operates the app itself and captures them.
   • Android: adb tap/screencap · iOS Simulator: deep links (simctl openurl) first, then idb, Maestro, or AppleScript
   • Status bar unified to 9:41 / 100% battery across every capture
   • You never have to touch the device — you only pick options and approve copy
   • On a re-run it first asks: reuse existing screenshots, or start fresh?
2. Questions (all multiple-choice) — platform (App Store / Google Play) → devices (iPhone, iPad, Galaxy, Fold, Flip) → style (match my app / modern-minimal / pop / dark) → how many slides → what to highlight
3. Draft approval — a copy table plus one fully rendered first slide at real store size; full rendering starts only after your OK
4. Render — frame, background, and copy composed in HTML/CSS, captured with headless Chrome
5. Verify — every PNG's pixel size is checked against the store spec table

Claude Code or Codex	either one — the skill runs in both
Chrome or Chromium	for headless rendering — falls back to Playwright automatically
sips (built into macOS) or ImageMagick	for pixel-size verification

🧩 Why this instead of a web tool?

• It reads your actual app. Colors come from your real design system, and the copy is written from what's actually on each screen — not from a template.
• It can capture for you. Most screenshot tools start from images you already have; this one can launch and navigate your app to get them.
• Nothing leaves your machine. No uploads, no accounts, no watermarks — plain HTML/CSS rendered locally.
• Korean-first, English-ready. Copy defaults to Korean and can generate an English set for international listings in the same layout.

❓ FAQ

What size do App Store screenshots need to be? For iPhone, 1320×2868 (6.9″) and 1284×2778 (6.5″) portrait — this skill always renders both sets, because App Store Connect can require the 6.5″ set depending on your app's device support.

Does it work for Google Play? Yes — 1080×1920 phone screenshots (Play's featuring guidelines want at least 1080px and 4+ slides), plus tablet and foldable coverage.

Do I need Figma or Photoshop? No. Frames, backgrounds, and text are composed in HTML/CSS and rendered with headless Chrome.

Can it make screenshots for a Galaxy Fold or Flip? Yes — Fold (with hinge line) and Flip frames are drawn in CSS, and the unfolded Fold screen can double as a Play tablet screenshot.
