## About

# Shotkit

End-to-end App Store screenshot pipeline for indie iOS developers. From raw Simulator capture to upload-ready assets organized by device, locale, and template style.

---

## What This Skill Does

**Stage 1 — Capture** (optional): Takes raw UI screenshots from the Xcode Simulator using `xcrun simctl`.

**Stage 2 — Generate Copy**: Produces locale-aware headlines + sublines for each screenshot frame.

**Stage 3 — Composite**: Renders styled screenshot images using Pillow — background, device mockup area, app UI screenshot, and text overlay.

**Stage 4 — Organize**: Outputs a folder structure compatible with `asc` CLI and App Store Connect upload.

## Workflow

### Step 1 — Collect Inputs

Ask the developer for the following (or infer from context if already provided):

**Required:**
- App name
- Core features to highlight (3–8 bullet points)
- Target audience (one sentence)
- Primary language (default: English)
- Additional locales (optional, e.g. Italian, German, Japanese)

**Screenshot source (choose one):**
- A) Auto-capture from booted Simulator → ask for app Bundle ID
- B) Existing screenshots folder → ask for path to folder of PNG/JPG files
- C) No UI screenshots yet → generate placeholder-based composites with colored UI mockups

**Template style (choose one, or generate previews for all):**
- `minimal` — white/light background, small device frame, centered text, clean typography
- `bold` — full-bleed gradient background, large text, high contrast, punchy
- `dark` — dark/black background, device glow effect, premium feel
- `editorial` — magazine-style layout, diagonal composition, text beside device
- `flat` — no device frame, full-bleed app UI with text overlay bar at top or bottom

**Device targets (default: iPhone 6.9" + iPad 13"):**
- iPhone 6.9" — 1320 × 2868 px (mandatory as of 2025)
- iPhone 6.7" — 1290 × 2796 px (legacy, still widely used)
- iPhone 6.5" — 1242 × 2688 px
- iPad 13" — 2064 × 2752 px (mandatory if app supports iPad)
- iPad 12.9" — 2048 × 2732 px

### Step 2 — Install Dependencies
```bash
cat > "$REPO/skills/shotkit/scripts/install_deps.sh" /dev/null; then
  echo "❌ Python 3 not found. Install via: brew install python3"
  exit 1
fi
echo "✅ Python $(python3 --version) found"
pip3 install Pillow --quiet --break-system-packages 2>/dev/null \
  || pip3 install Pillow --quiet 2>/dev/null \
  || { echo "❌ Pillow install failed. Try: pip3 install Pillow"; exit 1; }
echo "✅ Pillow installed"
if command -v xcrun &>/dev/null; then
  echo "✅ xcrun found (Xcode present)"
else
  echo "⚠️  xcrun not found. Simulator capture will not work."
fi
echo ""
echo "✅ Dependencies ready."
