Updated: Aug 2026; last repo commit

This skill lists the screenshot sizes SKILL.md gives for the Apple App Store and Google Play, a screenshot order built on the first three images, four screenshot styles, caption rules, preview video lengths, localization and A/B testing. It adds belt app run commands that generate device scenes and clips.

It is one SKILL.md and needs the belt CLI from inference.sh plus an inference.sh login to run the generation commands.

Good for

Indie developers preparing an iOS or Android store listing
App marketers working on store optimization (ASO)
Designers who want caption rules and a screenshot order

Install app-store-screenshots

Claude Code

Copy this prompt.

Install the app-store-screenshots skill in Claude Code. Run this command:

npx skills add inference-sh/skills@app-store-screenshots

Then check that it loaded and tell me how to use it.

2
Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js.

The skill only does its image, video and search steps when the belt CLI is installed and logged in (SKILL.md Quick Start). The Homebrew and installer commands come from cli-install.md, which also lists npx and Scoop. The vendor README documents a Claude Code plugin route (/plugin marketplace add inference-sh/skills), but the repo has no .claude-plugin/marketplace.json (HTTP 404 on Nov 2, 2026) and the plugin would add every skill in plugin.json, so it is not listed here. This page installs from inference-sh/skills, the vendor's own repo.

Permissions

Medium risk

Claude can run belt commands that call AI apps through your inference.sh login. Read the first command before it runs and check app pricing before bigger jobs.

Watch out for

Claude runs belt commands for you
SKILL.md lists `Bash(belt *)` in allowed-tools and its commands call apps such as falai/flux-dev-lora, bytedance/seedream-4-5, infsh/stitch-images and google/veo-3-1-fast. Each command's --input is passed to the named app, so read prompts before they run. github.com
Running apps can use credits
The belt CLI skill documents belt balance (check credits) and belt app pricing (see cost formula before running). Check the price before large or repeated runs. github.com
You install the belt CLI separately
cli-install.md offers a curl installer, Homebrew, npx and Scoop. It says the installer downloads a binary from dist.inference.sh, verifies its SHA-256 checksum, and uses no elevated permissions, background processes or telemetry. github.com

Questions

What does app-store-screenshots do?

It makes Claude plan an app store listing: which sizes to export, what order to show screenshots in, how to write captions and how to structure a preview video. It also lists belt commands that generate device mockups and clips.

How do I install app-store-screenshots?

Use the install box above. It installs the skill folder, and you also need the belt CLI, which the SKILL.md links to in cli-install.md. Then run belt login, as SKILL.md's Quick Start does.

Does it need an account or API key?

It needs the belt CLI and a belt login to inference.sh. SKILL.md names these apps: falai/flux-dev-lora, bytedance/seedream-4-5, infsh/stitch-images and google/veo-3-1-fast. The belt CLI skill documents belt balance to check credits and belt app pricing to see the cost formula before running an app, so check pricing there.

Is it safe to use?

The skill's frontmatter allows Bash(belt *), so Claude can run belt commands that call AI apps on inference.sh. The files in this folder are one SKILL.md. Our advice: read the first belt app run command Claude proposes, and check an app's price with belt app pricing before large runs.

Is there another copy of app-store-screenshots?

Yes. skills.sh also lists a copy under 101-skills/superpowers, with many more installs. This page installs from inference-sh/skills, the vendor's own repo, and the facts here come from there. Pick one source so you do not get the skill twice.

What else does SKILL.md point to?

Its Related Skills section lists these installs from inference-sh/skills: ai-image-generation, ai-video-generation, image-upscaling and prompt-engineering. They are optional hand-offs, not requirements for the layout and spec advice in this skill.
