Are the ai2 Empty state command palettes free?

Yes. The whole styled layer is free and MIT licensed, like the component core.

Can I change the size?

Yes. Every variation takes a size prop of sm, md, lg or xl, aligned to the base Button height scale.

Empty state command palettes

Five command palettes built around the states that are usually an afterthought: no results, loading, error, recent searches and suggestions. Every state is reachable by typing in the real input. Each is self-contained (no cmdk), sized, token-driven, filters as you type and supports arrow keys plus Enter.

CommandEmpty

Installation

The styled layer is free and installs like any other ai2 component.

Run the following command

npx shadcn@latest add @ai2/command-empty

Dependencies, the @ai2/tokens theme and the component file are installed together.

Manual installs skip the @ai2/tokens theme, so add the token CSS from the theming guide or the tone colors will be missing.

Variations

5 takes on the same idea. Each is its own export, and every one accepts a size prop (sm, md, lg, xl) aligned to the base Button scale.

Empty

A written out no-results state with a clear action.

Loading

Skeleton rows for a fixed beat after every keystroke.

Error

A danger toned failure card with a retry.

Recent

Recent searches while the query is blank.

Suggest

Suggestion chips when nothing matches.

ai2 Empty state command palettes: 5 styled variations on the token system

The ai2 Empty state command palettes are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around the non-happy states of a command palette. They are free and MIT licensed, and every color comes from a semantic token, so they theme with the rest of ai2 in light and dark.

Motion runs on framer-motion: framer-motion fades the state panels in and out as the query changes. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the transforms are skipped and the panels fade or swap instantly.

What is in the ai2 Empty state command palettes?

5 exports in one file: Empty, Loading, Error, Recent and Suggest. Each renders a native button and takes a size prop (sm, md, lg, xl) aligned to the base Button. They are separate from the base Button on purpose: the base keeps its clean variant, tone and size axes, while the styled layer carries the effects.

You own the file. Copy the one category file and you have all 5 variations, with no runtime dependency on ai2 itself.

Why use it

On-system by construction: Every color resolves to an ai2 semantic token, so the buttons follow your theme in light and dark with no extra work.
Effect without the sprawl: The decorations live in a dedicated styled file, so the base Button keeps its clean, predictable API.
Accessible and honest: Each renders a real button element, keeps a visible focus ring, and respects prefers-reduced-motion.

Features

Token-driven color: No hardcoded hex or oklch; the look recolors with your theme tokens.
framer-motion: framer-motion fades the state panels in and out as the query changes.
Reduced-motion aware: Under prefers-reduced-motion, the transforms are skipped and the panels fade or swap instantly.
Size aligned to the base: Every variation takes sm, md, lg and xl matching the base Button height scale, so styled and base buttons line up in a row.

Production tips

Use it for emphasis, not everywhere: Styled buttons draw the eye. Reserve them for the one action you want people to take on a screen, and use the base Button for the rest.
Keep labels as verbs: The decoration adds weight, so a clear action label keeps the button scannable.
Pick one variation per surface: The variations share a family; using two different ones in the same view competes for attention.

Works with the rest of ai2

The Empty state command palettes sit alongside the base Button and the rest of the @ai2 registry. They share the same token file, so a styled action next to a base button or a badge stays visually consistent in both modes.
