Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionmobile-first-designExecute the skills CLI command in your project's root directory to begin installation:
Fetches mobile-first-design from aj-geddes/useful-ai-prompts and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate mobile-first-design. Access via /mobile-first-design in your agent's command palette.
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 environment. Always review source, verify the publisher, and test in isolation before production.

Mobile-first design prioritizes small screens as the starting point, ensuring core functionality works on all devices while leveraging larger screens for enhanced experience.
Minimal working example:
Mobile-First Approach:
Step 1: Design for Mobile (320px - 480px)
- Constrained space forces priorities
- Focus on essential content and actions
- Single column layout
- Touch-friendly interactive elements
Step 2: Enhance for Tablet (768px - 1024px)
- Add secondary content
- Multi-column layouts possible
- Optimize spacing and readability
- Take advantage of hover states
Step 3: Optimize for Desktop (1200px+)
- Full-featured experience
- Advanced layouts
- Rich interactions
- Multiple columns and sidebars
---
## Responsive Breakpoints:
Mobile: 320px - 480px
- iPhone SE, older phones
