Claude Skill Aso Appstore Screenshots — AI skill for Claude Code

ASO App Store Screenshots

A Claude Code skill that generates high-converting App Store screenshots for your iOS app. It analyzes your codebase, identifies core benefits, and creates professional screenshot images using AI.

What It Does

1. Benefit Discovery — Analyzes your app's codebase to identify the 3-5 core benefits that drive downloads
2. Screenshot Pairing — Reviews your simulator screenshots, rates them, and pairs each with the best benefit
3. Generation — Creates polished App Store screenshots using a two-stage process: deterministic scaffolding (compose.py) + AI enhancement (Nano Banana Pro via Gemini MCP)
4. Showcase — Generates a preview image with all screenshots side-by-side

Installation

1. Add the skill to Claude Code

claude install-skill github.com/adamlyttleapps/claude-skill-aso-appstore-screenshots

2. Install Python dependencies

pip install Pillow

3. Font requirement

The skill uses **SF Pro Display Black** for headline text. On macOS, install it from [Apple's developer fonts](https://developer.apple.com/fonts/). The expected path is:

/Library/Fonts/SF-Pro-Display-Black.otf

4. Set up Gemini MCP (for AI enhancement)

The generation phase requires [@houtini/gemini-mcp](https://www.npmjs.com/package/@houtini/gemini-mcp) to be configured as an MCP server in Claude Code:

npm install -g @houtini/gemini-mcp

Then add it to your Claude Code MCP config (`~/.claude/settings.json` or project `.mcp.json`).

Usage

From within your app's project directory, run:

/aso-appstore-screenshots

The skill will guide you through each phase interactively. Progress is saved to Claude Code's memory system, so you can resume across conversations.

How It Works

Scaffold → Enhance Pipeline

Rather than generating screenshots from scratch (which produces inconsistent results), the skill uses a two-stage approach:

1. compose.py creates a deterministic scaffold
