Design and Implement Mobile App Interfaces

Mobile app concepts often lack a coherent visual direction and implementation-ready details. This skill generates, reviews, and translates Sleek screens into working interfaces.

Agent request

Review the Skillstore skill "design-mobile-apps" from https://skillstore.io/skills/designed-by-ai-design-mobile-apps.md and its manifest at https://skillstore.io/api/skills/designed-by-ai-design-mobile-apps/manifest. Verify the artifact. Stop and obtain explicit user consent before installing or changing files.

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

Test it

Using "design-mobile-apps". Design an onboarding flow for a personal budgeting application.

Expected outcome:

Created a project with welcome, goals, account connection, and completion screens.
Applied a calm financial style with clear progress and restrained color.
Presented viewport screenshots and reviewed full-height captures.

Using "design-mobile-apps". Make the existing activity screen easier to scan during workouts.

Expected outcome:

Updated the targeted screen with stronger hierarchy, larger metrics, clearer controls, and preserved navigation. Presented the revised screenshot for review.

Using "design-mobile-apps". Implement the approved profile screen in React Native.

Expected outcome:

Retrieved the active component version and visual reference. Recreated the structure, typography, icons, imagery, and navigation for React Native.

Security Audit

High Risk

v8 • 9/8/2026 Open versioned report

Most static alerts are false positives caused by Markdown backticks, placeholder credentials, example URLs, and API documentation rather than executable shell syntax. The skill has intentional network access, while semantic review found unsafe conversational key handling, an inaccurate host boundary, and unvalidated external HTML.

False positives ignored

Confirmed security concerns (3)

High

SKILL.md:35

API Key Requested in Agent Conversation

The fallback explicitly asks the user to paste a newly created API key into the agent conversation, exposing the secret to model context and logs.

Line 35 directly instructs the user to paste the full key back to the agent, and states that the value is shown only once.

Medium

SKILL.md:7 SKILL.md:56 SKILL.md:184-192

Undeclared Third-Party Network Access

The skill declares only sleek.design and claims no third-party traffic, but later directs SVG downloads from api.iconify.design.

The allowlist and privacy claim are explicit, while lines 184 through 192 explicitly require network access to a different host.

Medium

SKILL.md:164 SKILL.md:280

Externally Generated HTML Used Without Validation

The skill instructs agents to save complete externally generated HTML directly and notes that default output imports a remote script.

The source explicitly identifies complete HTML and remote script loading, with no sanitization or inspection requirement before local use.

Capability review items (8)

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

Low

SKILL.md:12

Hardcoded URL

[![Design mobile apps in minutes](https://raw.githubusercontent.com/sleekdotdesign/agent-skills/main

The Markdown embeds an image from raw.githubusercontent.com, so a renderer may contact an undeclared host and disclose request metadata.

Low

SKILL.md:16

Hardcoded URL

[sleek.design](https://sleek.design) is an AI-powered mobile app design tool. You interact with it v

This line directs the agent to exchange user design content with the external Sleek REST service. The network use is intentional but security-relevant.

Low

SKILL.md:18

Hardcoded URL

**Base URL**: `https://sleek.design`

This URL is the configured destination for authenticated API traffic. It is expected vendor access, but it creates a real external data boundary.

Low

SKILL.md:23

Hardcoded URL

**API docs**: OpenAPI spec at `https://sleek.design/api/v1/spec.json`; browsable docs at `https://sl

The instruction explicitly tells the agent to fetch an external OpenAPI specification. This is intentional network access to the declared Sleek host.

Low

SKILL.md:31

Hardcoded URL

1. `POST https://sleek.design/api/v1/device/start` (no auth) with body `{"source": "your-tool-slug"}

The device authorization flow starts with an unauthenticated request to Sleek. The endpoint is expected, but the outbound request is real.

Low

SKILL.md:33

Hardcoded URL

3. Poll `POST https://sleek.design/api/v1/device/poll` with `{"deviceCode": "..."}` every `interval`

The agent is instructed to poll Sleek with a secret device code. This is legitimate authentication traffic but remains security-sensitive network use.

Low

SKILL.md:187

Hardcoded URL

GET https://api.iconify.design/{prefix}/{name}.svg

The skill explicitly directs the agent to download SVG content from api.iconify.design, a host absent from the declared allowlist.

Low

SKILL.md:190

Hardcoded URL

Example: `https://api.iconify.design/solar/heart-bold.svg`

This concrete Iconify URL supports the preceding instruction to download remote SVG assets from an undeclared third-party host.

What You Can Build

Explore a New Product

Turn a product brief into coordinated mobile screens with a defined visual direction.

Review Interface Variations

Create separate design directions, compare screenshots, and refine the selected option.

Implement Approved Screens

Retrieve component HTML and screenshots as references for a native application implementation.

Try These Prompts

Create a First Screen

Create a mobile welcome screen for [product]. Include [content] and use a [mood] visual direction.

Design a Core Flow

Design the [flow] for [audience]. Include [screens], preserve [brand requirements], and show screenshots of every generated screen.

Refine an Existing Screen

Update screen [screen name] in project [project]. Improve [specific issue] while preserving [elements]. Review the full-height result before reporting completion.

Implement a Native Interface

Implement the approved screens in [framework]. Fetch active component HTML, preserve exact icons and fonts, then verify navigation and layout against screenshots.

Best Practices

Provide product goals, audience, required screens, references, and constraints before generation.
Use scoped, revocable credentials and confirm any action that may consume credits or remove data.
Review full-height screenshots before requesting corrections, then verify native implementations against viewport screenshots.

Avoid

Do not paste API keys into prompts, chat messages, source files, or generated outputs.
Do not judge missing content from viewport screenshots without checking a full-height capture.
Do not substitute icons, fonts, screen identifiers, or component versions without confirming the change.

Frequently Asked Questions

What is required to use this skill?

You need network access, a Sleek account, and an API key with scopes appropriate for the task.

Can it create several screens?

Yes. A single design request can produce a coordinated flow with multiple screens.

Can it edit an existing Sleek project?

Yes. It can target an existing screen when you provide the project and screen context.

Does it support native mobile frameworks?

It provides HTML and screenshots as references for React Native, SwiftUI, and other native implementations.

Does it require a paid Sleek plan?

Trial credits may support an initial design. Continued generation can require a paid plan.

How should generated screens be reviewed?

Use viewport screenshots for presentation and full-height screenshots for completeness checks. Inspect component HTML when a negative visual conclusion remains uncertain.
