Overview

Show selected-object metadata and actions in a compact side panel. This entry is written as a registry-ready component spec: useful to humans, copyable by AI tools, and easy to map to a future shadcn registry item.

Accessibility notes

Use semantic HTML or the matching Radix primitive before custom roles.
Keep focus-visible states obvious without adding decorative glow.
Ensure icon-only controls have an accessible label.
Do not rely on color alone for state or validation.

shadcn/ui sheet

shadcn implementation

Use Radix Dialog through the matching shadcn component when possible.

Use shadcn tokens for background, border, ring, muted text, radius, and state variants. Keep component-specific classes local and copyable.

optional adapter

HeroUI mapping

Inspector Panel can map to a HeroUI component only as an optional adapter. Keep UnBoring copy and token language framework-neutral.

AI Prompt

Create a Inspector Panel component for an AI-generated interface using shadcn-style composition. Use shadcn/ui sheet as the implementation base. The component should support default, muted, outline, ghost, destructive variants and default, open, hover, focus-visible, disabled states. Include clear anatomy for Root, Handle, Header, Content, Action area. Keep the visual language black, white, and gray with subtle borders, practical spacing, accessible focus states, and no decorative noise.

Negative Prompt

Do not invent a custom component API when shadcn/ui sheet already covers the base behavior. Avoid random gradients, oversized radii, unclear disabled states, missing labels, icon-only controls without accessible names, and variants that change layout unexpectedly.

Implementation Notes

Base: shadcn/ui sheet
Primitive: Radix Dialog
Tailwind: Use shadcn tokens for background, border, ring, muted text, radius, and state variants. Keep component-specific classes local and copyable.
Dependency: Use Radix Dialog through the matching shadcn component when possible.

Usage notes

Short guidance for humans and AI tools before copying the component.

What is this component for?

Inspector Panel helps teams show selected-object metadata and actions in a compact side panel. It should feel like a reusable product primitive, not a one-off decoration.

How should I implement it?

Start from shadcn/ui sheet. Use Radix Dialog through the matching shadcn component when possible. Keep variants token-driven and keep states predictable.

What should I avoid?

Do not invent a custom component API when shadcn/ui sheet already covers the base behavior. Avoid random gradients, oversized radii, unclear disabled states, missing labels, icon-only controls without accessible names, and variants that change layout unexpectedly.
