ASO App Store Screenshots — workflow skill for product videos

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

App Store screenshots from your codebase: finds the core benefits, pairs simulator shots, then composes and enhances.

What it does

Adam Lyttle's skill for iOS developers. It reads your app's codebase to draft the three to five benefits that drive downloads, reviews your simulator screenshots and coaches retakes, pairs each screenshot with a benefit, then generates App Store Connect-sized images in two stages: a deterministic scaffold (compose.py places the headline, device frame and screenshot) followed by an AI enhancement pass with Nano Banana Pro through a Gemini MCP server. Progress is saved to Claude Code's memory so the work resumes across sessions, and a showcase image previews the full set.
