Agent request

Review the Skillstore skill "app-store-screenshots" from https://skillstore.io/skills/halt-catch-fire-app-store-screenshots.md and its manifest at https://skillstore.io/api/skills/halt-catch-fire-app-store-screenshots/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "app-store-screenshots". I need screenshots for a habit tracker on iOS.

Expected outcome:

Recommended gallery: hero outcome first, weekly progress second, reminders third, social proof fourth, and customization screens later.

Using "app-store-screenshots". My Google Play listing needs a better first screenshot.

Expected outcome:

Lead with the clearest user benefit, use one short caption, show the app in use, and reserve settings screens for later positions.

Using "app-store-screenshots". I want to localize screenshots for three markets.

Expected outcome:

Prioritize translated captions for all markets, then rebuild screenshots where culture, examples, currency, or device language affects comprehension.

Security Audit

Medium Risk

v5 • 7/9/2026 Open versioned report

Most static command hits are Markdown fences, inline CLI names, or documentation examples rather than dynamic shell execution. Confirmed risks are limited to third-party CLI installation guidance, belt commands that call external generation services, and remote processing of prompts or app imagery.

Third-Party Asset Processing Through belt

The skill directs users to create screenshots and videos through the inference.sh belt CLI. Prompts and referenced app images may be processed by an external service, so private app assets need explicit user approval.

The documentation explicitly depends on inference.sh and shows belt app run commands for remote image, stitching, and video generation. The risk is privacy exposure, not evidence of malicious intent.

Capability review items (9)

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Medium

SKILL.md:7

Ruby/shell backtick execution

> **Install the belt CLI skill:** `npx skills add belt-sh/cli`

The line recommends running npx to install a third-party CLI skill. That can download and execute external package code during setup, so it is a real supply-chain risk.

Medium

SKILL.md:17-26

Ruby/shell backtick execution

```bash

The fenced example runs belt login and belt app run against a remote model service. The arguments are static, but execution requires authentication and sends prompt data to an external CLI.

Medium

SKILL.md:137-144

Ruby/shell backtick execution

```bash

The example invokes belt app run to submit a prompt to a third-party image generation model. It is intentional functionality, but still external command and network execution.

Medium

SKILL.md:148-154

Ruby/shell backtick execution

```bash

The cited code block runs belt app run with a remote image model. The command is hardcoded, but it still sends prompt content to an external service.

Medium

SKILL.md:158-165

Ruby/shell backtick execution

```bash

The example invokes belt app run for remote image generation. It is a legitimate workflow, but it can transmit user prompt details to the external provider.

Medium

SKILL.md:169-175

Ruby/shell backtick execution

```bash

The example runs belt app run with local image filenames for stitching. If executed, app screenshots may be read or uploaded by the external CLI workflow.

Medium

SKILL.md:206-211

Ruby/shell backtick execution

```bash

The example invokes belt app run against a remote video generation model. It is legitimate for the skill, but it is still external command execution with network transfer.

Medium

SKILL.md:262-267

Ruby/shell backtick execution

```bash

The related skills block recommends multiple npx skills add commands. Installing third-party skills through npx introduces supply-chain and code provenance risk.

Low

SKILL.md:15

Hardcoded URL

> Requires inference.sh CLI (`belt`). [Install instructions](https://raw.githubusercontent.com/infer

The line links to mutable raw GitHub install instructions for a required external CLI. This is a low-severity supply-chain concern because users may follow unaudited setup content.

What You Can Build

Prepare an iOS Launch Gallery

Plan screenshot sizes, order, captions, and hero messaging for a new App Store release.

Refresh Google Play Assets

Create a concise asset plan for screenshots, feature graphics, and preview media before a listing update.

Localize Store Screenshots

Prioritize markets and decide where captions, screenshots, and gallery order need local adaptation.

Try These Prompts

Plan a Screenshot Gallery

Use this skill to plan a screenshot gallery for my mobile app. The app is [app type], the top benefit is [benefit], and the target store is [Apple App Store or Google Play].

Write Benefit Captions

Create benefit-focused captions for these app screens: [screen list]. Keep each caption readable in a store screenshot and limit it to two lines.

Generate Mockup Prompts

Draft belt-compatible image generation prompts for a screenshot set. Include a hero mockup, a feature callout, and a lifestyle context image for [app details].

Audit a Full Listing Strategy

Review my planned store screenshot strategy for [app]. Check platform fit, first-three impact, caption clarity, localization needs, and A/B testing opportunities.

Best Practices

Start with the strongest user outcome in the first screenshot.
Keep captions short, benefit-focused, and readable at store thumbnail sizes.
Verify dimensions and media rules against current store documentation before submission.

Avoid

Using onboarding or settings screens as the first screenshots.
Writing feature labels when a user benefit would be clearer.
Submitting generated visuals without checking brand accuracy and store policy fit.

Frequently Asked Questions

Does this skill create final store assets by itself?

It provides planning guidance and belt CLI generation examples. Users still need to review, resize, and submit final assets.

Which stores does it cover?

It covers Apple App Store and Google Play screenshot guidance, including dimensions, gallery limits, and preview media notes.

Can Claude, Codex, and Claude Code use it?

Yes. The report marks support for Claude, Codex, and Claude Code.

Does it require external services?

Yes. Generation examples require the belt CLI and inference.sh access.

Can it help with localization?

Yes. It suggests market priorities and when to translate captions or rebuild screenshots.

Can it validate Apple or Google approval?

No. It gives preparation guidance, but users must verify current platform rules and review assets before submission.
