app-store-screenshots

What This Skill Does

The app-store-screenshots skill is a specialized OpenClaw agent tool designed to streamline the creation and optimization of high-converting store assets. It bridges the gap between raw app UI and professional marketing materials by providing exact platform specifications for both the Apple App Store and Google Play Store. The skill leverages advanced inference models to generate device-specific mockups, ensures adherence to critical platform dimensions, and provides strategic guidance on the 'First 3 Rule'—the marketing principle where the first three screenshots determine 80% of conversion success. Whether you are generating PNGs for iOS or managing 16:9 aspect ratios for Android, this skill acts as both a design consultant and an implementation bridge.

Installation

To integrate this skill into your environment, use the OpenClaw Hub CLI:

clawhub install openclaw/skills/skills/okaris/app-store-screenshots

Ensure that you have your inference credentials configured, as the skill interacts with the inference.sh CLI to generate the visual mockups. No elevated system permissions are required for the installation.

Use Cases

• ASO Optimization: Auditing and replacing underperforming screenshots to increase store conversion rates.
• New App Launch: Creating a complete gallery set including the hero image, feature highlights, and social proof, following the 10-screenshot threshold for iOS and 8-screenshot limit for Android.
• A/B Testing: Rapidly generating multiple variations of screenshots with different caption styles or backgrounds to test user engagement.
• Marketing Collateral: Producing professional device mockups for press kits or social media promotion using high-fidelity rendering prompts.

Example Prompts

1. "Generate a set of 3 iPhone 15 Pro screenshots for a fitness app. The first should highlight the workout tracker, the second the social leaderboard, and the third the progress analytics. Use a clean, light-mode style with a minimal background."
2. "I need 16:9 Android play store screenshots for my productivity app. Create a mockup showing a 'Done' task animation on a Pixel 8 frame."
3. "Help me optimize my app store gallery. I have a travel booking app; suggest a sequence for my 5 screenshots based on the 'First 3 Rule' and provide the prompt to generate the hero shot."

Tips & Limitations

• Prioritize the Hero: Your first screenshot must be the strongest. If you are not seeing a spike in install rates, move your most unique differentiator to position #1.
• Mind the Constraints: Always check for transparency in JPEG files; the app store will reject files with alpha channels on JPEGs. The tool helps, but manual verification of the exported files against platform guidelines is recommended.
• Resolution: Note that Google Play supports up to 3840px, while Apple has very specific requirements (e.g., 1290x2796 for the 6.7" display). Ensure you select the correct device profile when running the inference command.
