UI Handler

Instructions

1. Installing Standard Components (Atoms)

Use the Shadcn MCP for foundational UI elements (buttons, inputs, dialogs).

Action: Ask the Shadcn MCP to add the component.

"Add the button and dialog components using Shadcn MCP."
Manual Fallback: pnpm dlx shadcn@latest add {component}

2. Generating Complex Sections (Blocks)

Use the 21st.dev Magic MCP for high-level sections (Landing pages, Heros, Dashboards).

Action: Prompt the 21st.dev MCP with a description.

"Generate a modern SaaS hero section with a dark gradient background and email capture form."
Location: Place generated files in src/components/sections/ or src/components/website/.
Integration: Import and use in your page.tsx.

3. Theming & Styling

Use Shadcn MCP or edit src/app/globals.css directly.

Theme Updates: Ask Shadcn MCP to apply a specific theme or color palette.

"Update the app theme to use a 'zinc' neutral base with 'blue' primary color."
CSS Variables: We use CSS variables (often OKLCH) in src/app/globals.css. Ensure any new styles use these variables (e.g., bg-background, text-primary).

4. Creating Layouts

Identify: Header, Sidebar, Content Area.
Compose: Use atoms from @/components/ui and sections from @/components/sections.
Co-location: If a component is unique to a page, put it in _components/ next to the page.
