## Capabilities

- Create and manage Sleek projects through documented API endpoints.
- Send natural language design prompts to generate or update mobile screens.
- Poll asynchronous chat runs and handle sync wait responses.
- List project components and select target screens for edits.
- Render individual or combined screenshots for created and updated screens.
- Apply pagination, idempotency, and conflict-handling guidance.

## Use Cases

- Create a New App Concept: Turn a short product idea into a Sleek project with generated mobile screens and screenshots.
- Iterate Existing Screens: Send focused update prompts to refine a selected screen and review the updated screenshot.
- Document Design Progress: List components, capture screenshots, and share visual progress after each completed design run.

## Prompt Templates

### Start a Simple App

```
Create a Sleek project for a budgeting app and generate the first mobile screen. Show me the screenshot after it finishes.
```

### Generate Several Screens

```
Design a mobile onboarding flow for a meditation app with welcome, goal selection, and subscription screens.
```

### Edit a Target Screen

```
Find the profile screen in my Sleek project, make it cleaner, and show the updated screenshot.
```

### Run an Advanced Workflow

```
Create a travel planner app concept, poll until complete, capture each new screen, and include one combined screenshot of all screens.
```

## Limitations

- Requires a SLEEK\_API\_KEY and Pro\+ API access.
- Sends prompts and optional reference image URLs to Sleek services.
- Only supports HTTPS reference images and documented Sleek endpoints.
- Does not include executable client code or a local design renderer.

## Best Practices

- Use the smallest API key scope set needed for the requested task.
- Show screenshots after each completed screen creation or update run.
- Use idempotency keys when retrying a message after a network failure.

## Anti Patterns

- Do not send sensitive reference image URLs unless the user approves.
- Do not start another chat run before the active run completes.
- Do not assume a result exists while a run is still queued or running.

## Security Audit

- Audited at: 2026-07-09T15:36:38.866\+00:00
- Summary: All static findings were false positives caused by Markdown code ticks, API examples, documented SLEEK\_API\_KEY usage, and host references. No prompt injection, hidden command execution, undisclosed exfiltration endpoint, or social-engineering intent was found in SKILL.md.
