What This Skill Does

The app-store-screenshots-generator is a specialized skill designed for developers and product designers who need to create professional-grade marketing assets for their iOS applications. Instead of relying on generic drag-and-drop tools, this skill uses a code-first approach to generate high-fidelity Apple App Store screenshots. By leveraging a Next.js environment combined with Tailwind CSS and the html-to-image library, it allows you to treat your marketing assets as version-controlled code. The generator automatically handles the technical requirements of the App Store, including the complex resolution standards for various iPhone screen sizes (6.9", 6.5", 6.3", and 6.1").

Beyond simple resizing, this tool excels at creating "advertisement-style" slides. It focuses on the psychological aspect of mobile marketing by helping you craft compelling copy and visual layouts that highlight feature benefits rather than just displaying static UI elements. It manages everything from project scaffolding and font integration to the precise pixel-perfect rendering of device mockups.

Installation

To integrate this capability into your workflow, use the OpenClaw installation command. This will pull the necessary blueprints from the source repository and initialize the generator within your workspace:

clawhub install openclaw/skills/skills/adisinghstudent/app-store-screenshots-generator

Once installed, the agent will have access to the generator templates, allowing you to trigger screenshot creation directly from your natural language prompts.

Use Cases

This skill is ideal for:

• Rapidly prototyping screenshot sets for A/B testing on the App Store.
• Maintaining brand consistency across multiple localized app store pages (e.g., German, Arabic, Japanese).
• Developers who prefer managing marketing assets inside their IDE rather than jumping between third-party design platforms.
• Teams requiring automated re-generation of assets whenever the app's UI or brand palette changes.

Example Prompts

1. "Build a set of 5 App Store screenshots for my meditation app. Use a serene color palette with soft blues, focus on the mindfulness features, and ensure the text is easily readable."
2. "Generate screenshots for my fitness tracker app in both English and Spanish. I need 4 slides that highlight social leaderboards and habit streaks using a high-contrast dark mode style."
3. "Create a series of slides for my productivity tool. Keep the design minimalist, use a bold sans-serif font, and include iPhone 16 Pro Max resolution exports."

Tips & Limitations

For the best results, provide the agent with your brand hex codes and your app's main value proposition before it starts the generation process. While this tool handles the heavy lifting of layout and export, you should verify the final copy against Apple's strict review guidelines. Note that this skill primarily functions within a local environment; you must run the Next.js development server to trigger the final PNG exports via the browser.
