Designing with Sleek

Design mobile apps in minutes

Overview

sleek.design is an AI-powered mobile app design tool. You interact with it via a REST API at /api/v1/* to create projects, describe what you want built in plain language, and get back rendered screens. All communication is standard HTTP with bearer token auth.

Base URL: https://sleek.design Auth: Authorization: Bearer $SLEEK_API_KEY on every /api/v1/* request Content-Type: application/json (requests and responses) CORS: Enabled on all /api/v1/* endpoints


Prerequisites: API Key

Create API keys at https://sleek.design/dashboard/api-keys. The full key value is shown only once at creation — store it in the SLEEK_API_KEY environment variable.

Required plan: Pro or higher (API access is gated)

Key scopes

Scope What it unlocks
projects:read List / get projects
projects:write Create / delete projects
components:read List components in a project
chats:read Get chat run status
chats:write Send chat messages
screenshots Render component screenshots

Create a key with only the scopes needed for the task.


Security & Privacy

  • Single host: All requests go exclusively to https://sleek.design. No data is sent to third parties.
  • HTTPS only: All communication uses HTTPS. The API key is transmitted only in the Authorization header to Sleek endpoints.
  • Minimal scopes: Create API keys with only the scopes required for the task. Prefer short-lived or revocable keys.
  • Image URLs: When using imageUrls in chat messages, those URLs are fetched by Sleek's servers. Avoid passing URLs that contain sensitive content.

Create project

POST /api/v1/projects
Authorization: Bearer $SLEEK_API_KEY
Content-Type: application/json

{ "name": "My New App" }

Response 201 — same shape as a single project.

Get / Delete project

GET    /api/v1/projects/:projectId
DELETE /api/v1/projects/:projectId   → 204 No Content

Components

List components

GET /api/v1/projects/:projectId/components?limit=50&offset=0

    }
  ],
  "pagination": { "total": 5, "limit": 50, "offset": 0 }

Get component

Fetches a single component by ID. Use this when you need the code for a specific screen (e.g., after a chat run returns a componentId in its operations).

GET /api/v1/projects/:projectId/components/:componentId
Authorization: Bearer $SLEEK_API_KEY

Response 200 — same shape as a single item from the list endpoint:

{
  "data": {
    "id": "cmp_xyz",

    "versions": [{ "id": "ver_001", "version": 1, "code": "<!DOCTYPE html>...</html>", "createdAt": "..." }],
    "createdAt": "...",
    "updatedAt": "..."
  }
}

Chat — Send Message

This is the core action: describe what you want in message.text and the AI creates or modifies screens.

POST /api/v1/projects/:projectId/chat/messages?wait=false
Authorization: Bearer $SLEEK_API_KEY
Content-Type: application/json
idempotency-key: <optional, max 255 chars>

{
  "message": { "text": "Add a pricing section with three tiers" },
  "imageUrls": ["https://example.com/ref.png"],
  "target": { "screenId": "scr_abc" }
}
Field Required Notes
message.text Yes 1+ chars, trimmed
imageUrls No HTTPS URLs only; included as visual context
target.screenId No Edit a specific screen using its screenId (not componentId); omit to let AI decide
?wait=true/false No Sync wait mode (default: false)
idempotency-key header No Replay-safe re-sends

Response — async (default, wait=false)

Status 202 Accepted. result and error are absent until the run reaches a terminal state.

{
  "data": {
    "runId": "run_111",
    "status": "queued",
    "statusUrl": "/api/v1/projects/proj_abc/chat/runs/run_111"
  }
}

Response — sync (wait=true)

Blocks up to 300 seconds. Returns 200 when completed, 202 if timed out.

{
  "data": {
    "runId": "run_111",
    "status": "completed",
    "statusUrl": "...",
    "result": {
      "assistantText": "I added a pricing section with...",
      "operations": [
        { "type": "screen_created", "screenId": "scr_xyz", "screenName": "Pricing", "componentId": "cmp_xyz" },
        { "type": "screen_updated", "screenId": "scr_abc", "componentId": "cmp_abc" },
        { "type": "theme_updated" }
      ]
    }
  }
}

Chat — Poll Run Status

Use this after async send to check progress.

GET /api/v1/projects/:projectId/chat/runs/:runId
Authorization: Bearer $SLEEK_API_KEY

Response — same shape as send message data object:

how to use sleek-design-mobile-apps

How to use sleek-design-mobile-apps on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • Cursor installed and configured on your development machine
  • Node.js version 16.0+ with npm package manager (verify with node --version)
  • Active project directory or workspace where you want to add sleek-design-mobile-apps
2

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/sleekdotdesign/agent-skills --skill sleek-design-mobile-apps

The skills CLI fetches sleek-design-mobile-apps from GitHub repository sleekdotdesign/agent-skills and configures it for Cursor.

3

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?
│ ── Universal (.agents/skills) ── always included ────
│ • Amp
│ • Antigravity
│ • Cline
│ • Codex
│ ●Cursor(selected)
│ • Cursor
│ • Windsurf
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/sleek-design-mobile-apps

Reload or restart Cursor to activate sleek-design-mobile-apps. Access the skill through slash commands (e.g., /sleek-design-mobile-apps) or your agent's skill management interface.

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

  3. 3.Evaluate output quality and relevance
  4. 4.Iterate on prompts to improve results
  5. 5.Integrate into regular workflow if valuable

Common Pitfalls

  • Expecting perfect results without iteration
  • Not providing enough context in prompts
  • Using skill for tasks outside its intended scope
  • Accepting outputs without review and validation

Best Practices

✓ Do

  • +Start with clear, specific prompts
  • +Provide relevant context and constraints
  • +Review and refine all outputs before using
  • +Iterate to improve output quality
  • +Document successful prompt patterns

✗ Don't

When to Use This

✓ Use When

Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.

✗ Avoid When

Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.

Learning Path

  1. 1Familiarize yourself with skill capabilities and limitations
  2. 2Start with low-risk, non-critical tasks
  3. 3Progress to more complex and valuable use cases
  4. 4Build expertise through regular use and experimentation
