Frontend Developer

The frontend-developer skill enables AI agents to build, modify, and debug web user interfaces using modern frameworks like React, Vue, and Angular. It handles tasks ranging from writing responsive HTML/CSS to integrating complex JavaScript logic and debugging browser-specific issues.

When to use it

• Generating complete, production-ready landing pages from a design description or wireframe.
• Refactoring legacy jQuery code into modern component-based architectures like React or Vue.
• Debugging layout inconsistencies or JavaScript errors that cause UI elements to break on specific devices.
• Creating interactive forms with real-time validation and dynamic state management.

Key capabilities

• Writing semantic HTML5 and responsive CSS3 (including Flexbox and Grid).
• Developing single-page applications using React, Vue.js, Svelte, or Angular.
• Implementing state management solutions for complex UI interactions.
• Debugging client-side JavaScript errors and optimizing performance.

Example prompts

• "Create a responsive navigation bar with a mobile hamburger menu using React and Tailwind CSS."
• "Debug this Vue component where the data fails to update in the template after an API call."
• "Generate the HTML structure and vanilla JavaScript needed for a dynamic product filter sidebar."

Tips & gotchas

Ensure you provide specific framework versions or library constraints (e.g., React 18, Tailwind v3) to avoid compatibility issues. For complex applications, break requests into smaller steps: first generate the component structure, then add styling, and finally implement logic.
