| description | Generate App Store and Play Store deployment assets — iPhone screenshots, iPad screenshots, and a Play Store feature graphic — from raw app UI screenshots. Use this skill whenever the user has app screenshots and wants to publish to the App Store or Google Play, mentions "store screenshots", "marketing screenshots", "feature graphic", "app store assets", "App Store Connect", "Play Console", "Google Play listing", or asks how to prepare their app's listing for submission. Trigger this even when the user just uploads phone screenshots and says something vague like "make these look good for the store" or "I'm submitting my app, help me with the visuals" — those are still this skill. |
deploy-ss
Take raw app UI screenshots and produce a polished, store-ready set of marketing visuals at the exact dimensions Apple and Google require.
What this produces
Three deliverables per run, all in the user's chosen output directory:
| Deliverable | Dimensions | Purpose | Count |
|---|
| iPhone screenshots | 1284 × 2778 | App Store iPhone 6.5"/6.7" Display slot; also accepted by Play Store | one per screen entry |
| iPad screenshots | 2048 × 2732 | App Store iPad 12.9"/13" Display slot | one per screen entry |
| Feature graphic | 1024 × 500 | Play Store hero banner | 1 |
Files are named phone_NN_<slug>.png, ipad_NN_<slug>.png, and feature_graphic_1024x500.png — stable and self-describing so the user can re-run and replace cleanly.
For UTXO this currently means a 6-screen lineup — Markets · Portfolio · Charts · Depth · News · Favorites — captured per platform: feed iOS-simulator raws to produce the App Store screenshots/ set (phone + iPad + feature graphic), and run again over Android-emulator raws with --skip-ipad --skip-feature to produce the framed play-store/ set. Both use the same iPhone-styled bezel; each carries its own platform's status bar.
When to use this skill
Trigger on any of these:
- The user uploads 3–8 phone screenshots and asks for store-ready visuals
- The user mentions submitting to App Store Connect or Google Play Console
- The user asks for a "feature graphic" or "store banner"
- The user shows a marketing template (e.g. UI8/Mobbin) and says "make screenshots like this for my app"
If the user only wants ONE of the three deliverables (e.g. just the feature graphic), still use this skill — pass --skip-phone --skip-ipad to the generator.
Workflow
Follow these steps in order. Don't skip the inventory step — picking the right screenshot for each slot is what makes the output good.
1. Inventory the user's screenshots
List the uploaded files. View each image with the view tool to see what feature it shows. Categorize each one — typical buckets: home/list, detail/chart, settings, profile, onboarding, empty state. Do NOT ask the user "what does this screenshot show" — figure it out by looking.
2. Propose a 5–6 screen plan
Pick the most distinctive screenshots (5–6 works well; App Store allows up to 10). Lead with the screen that best sells the app, and put a flagship/new feature early — for UTXO, Portfolio sits at slot 2, right after Markets. For each, decide:
- slot tag — short ALL-CAPS label (4–10 chars): MARKETS, CHARTS, INBOX, SETTINGS, etc. This is the pill above the headline.
- headline — 2 lines, hand-broken with
\n. Inter Black, very large. Punchy: "Track live\ncrypto markets" not "A complete real-time market tracking solution".
- subtitle — 1 sentence, ≤14 words. Reinforces the headline with concrete detail (named features, named integrations).
- theme —
"dark" or "light". Match the screenshot's actual background — placing a dark-mode screenshot on a cream canvas looks wrong.
Aim for a mix of dark/light themes (e.g. 3 dark + 2 light) so the set has visual rhythm when the user scrolls through the App Store listing.
Present the plan as a table to the user and get one round of feedback before generating. Don't push back hard if the user wants different copy — they know their app.
3. Pick a brand color
Default to a hue that fits the app category:
| Category | Default brand color |
|---|
| Crypto / Bitcoin-leaning | #F27C2F (Bitcoin orange) |
| Finance / banking | #2454C8 (deep blue) |
| Productivity / dev tools | #7C3AED (violet) |
| Health / fitness | #16A34A (green) |
| Social / lifestyle | #E11D48 (rose) |
| Photo / creative | #0EA5E9 (sky) |
Ask the user: "Brand color — go with <default> or do you have a specific hex?" One question, not a five-question interview.
4. Pick the feature-graphic screenshot
Pick the ONE screenshot that most clearly says "this is what the app does" at a glance. For a list-based app, that's the home/list screen. For a chart-based app, the chart. Avoid screens that need context to understand (settings, empty states, modals).
5. Build the config and generate
Write the config JSON to a temp file (e.g. /tmp/deploy-ss-config.json). See references/config-schema.md for the full schema, or copy and modify examples/config.example.json.
Run from the skill's scripts/ directory:
python3 <skill-path>/scripts/generate.py \
--config /tmp/deploy-ss-config.json \
--uploads <path-to-user-uploads> \
--output <path-to-output>
The script needs Pillow. Install with pip install --break-system-packages pillow if it's missing.
6. Present the results
Show the user the produced files. Give them the file paths and a short summary of what's in each (e.g. "phone_01_markets is your home-screen pitch, dark theme"). Mention dimensions for confidence.
Offer to regenerate any individual screen with different copy — re-running the generator with a tweaked config is fast.
7. Refresh the README (always)
After the assets land in screenshots/ and play-store/, update README.md so the showcase matches the regenerated set — the phone table, the iPad table, the feature-graphic reference, and any per-platform caption. Keep the column order identical to the screen lineup (Markets · Portfolio · Charts · Depth · News · Favorites). This is a standing step, not an optional one: every deploy-ss run leaves the README in sync. Also bump the screenshot counts in AGENTS.md if the lineup size changed.
Special cases
Capturing fresh raws + seeding demo data. When there are no good raws to start from (or the UI changed), capture them yourself: drive the iOS simulator (xcrun simctl io <udid> screenshot, navigate via computer-use) and the Android emulator (adb exec-out screencap, navigate via adb shell input). Capture in two passes — set appTheme in the persisted settings.json to Dark, capture the dark screens, then Light for the light ones. For data-driven screens, seed believable state into that same settings.json before launching (force-stop → write file → relaunch). For the Portfolio screen, seed wallets from the Hyperliquid public leaderboard — see references/design-guide.md § "Demo data for the raw captures".
Empty-looking screens. If a screenshot has lots of empty space (e.g. a Favorites screen with one item), the iPhone version can use a collapse_middle preprocess to glue the top content to the bottom navbar. See references/design-guide.md § "Handling sparse screens". The iPad version should use the original screenshot — collapsing makes the centered phone look stubby.
App name with a logomark letter. The feature graphic supports an accent_letter treatment — one letter of the app name is rendered on top of an accent-colored disc (e.g. UTXO with the "O" on a Bitcoin-orange disc). Use this when the app name has a short, distinctive letter that can carry brand weight. Skip it for long or generic names.
Non-standard screenshot sizes. The script accepts any aspect ratio — it just resizes proportionally. If the user uploads Android screenshots (e.g. 1080 × 2400), they'll work fine.
Fewer than 5 screenshots. Generate as many as the user has. App Store accepts 3 minimum; Play Store accepts 2.
