Delegation board

Pigeonholes for delegated work, one per subagent: its task slip, a lamp and a word for its status, and its progress. Finished work rises out of its cubby.

A coordinator's subagents

Four agents working in parallel. Drafting stops to ask you a question; answer it to unblock Review.

Built from

Delegation board is made of components that also work on their own.

Name tag
Who someone is: an agent, a person, a guest. The “HELLO my name is” sticker, a visitor badge for outside collaborators, and a plain tag for lists.

Installation

Add with the CLI

Once per project, add the Bevel registry to components.json.

components.json

{
  "registries": {
    "@bevel": "https://bevel-ui.vercel.app/r/{name}.json"
  }
}

Add Delegation board. This brings in Name tag and the Bevel foundation, installs @base-ui/react and cn, and merges the styles into your global CSS.
Terminal
```
npx shadcn@latest add @bevel/delegation-board
```

Install manually

Install the dependencies.
Terminal
```
pnpm add @base-ui/react cn
```

Add the Bevel foundation, if you haven't already. Light, depth, materials, motion and shape tokens, plus the utilities components use to apply them.

styles/bevel.css

/*
 * Bevel foundation. Every component builds on these tokens and utilities;
 * component stylesheets only add their own palettes and shapes.
 *
 * Layers:
 *   1. Light     one source, above and slightly in front of the screen.
 *   2. Depth     named elevations built from the light: recessed, flush,
 *                raised, pressed, object.
 *   3. Material  a surface recipe (leather, plastic, metal) that reads
 *                --bevel-material and --bevel-material-edge.
 *   4. Motion    two curves, a spring, and durations named by purpose.
 *   5. Shape     radii, stitching, and the type scale for amounts.
