⛔ Forbidden Patterns

1. NO Built-in Styles: Do NOT expect components to look "good" out of the box. They are unstyled. You MUST apply CSS/Tailwind classes.
2. NO Missing Portals: Always use <Component.Portal> for overlays (Dialog, Popover, Tooltip, Select) to avoid z-index/clipping issues.
3. NO Manual ARIA: Do NOT manually add role, aria-expanded, etc. Kobalte manages this.
4. NO Direct Input in Select: Use <Select> for button-triggered lists. Use <Combobox> if you need a text input.
5. NO Skipping Root: All parts must be nested within the Root component (or passed via Context).

🤖 Agent Tool Strategy

1. Styling Strategy: Check if Tailwind is used. If so, recommend @kobalte/tailwindcss plugin for ui-selected: modifiers.
2. Composition: Always show the full structure: Root -> Trigger -> Portal -> Content.
3. Accessibility: Emphasize that Kobalte handles focus management and keyboard nav automatically.
4. Integration: Kobalte works perfectly with @opentui/solid (if using standard DOM renderer) or web projects.

Quick Reference (30 seconds)

Kobalte Specialist - Accessible, Headless Primitives for SolidJS.

Philosophy:

• Headless: Logic only. You bring the UI/CSS.
• Accessible: WAI-ARIA APG compliant out of the box.
• Composable: Build complex UIs from granular parts.

Styling via Data Attributes:

• [data-expanded]: Component is open.
• [data-selected]: Item is active.
• [data-disabled]: Component is inactive.
• [data-highlighted]: Item is focused via keyboard.

Anatomy:

1. Root: State container.
2. Trigger: Toggle button.
3. Portal: Renders overlay at body root.
4. Content: The actual popup/panel.
