Task plan

An agent's plan on a legal pad. Finished steps are ticked in ink, the current one is underlined in red pen, the rest are still in pencil.

An agent at work

The plan advances on its own. Each step is ticked in ink as it finishes.

Review the Harbor Street lease

1 of 5 donex

Done: Read the lease and schedules
In progress: List every notice clause
Not started: Check notice periods against the playbook
Not started: Draft a redline
Not started: Summarise for Priya

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 Task plan. This brings in the Bevel foundation, installs @base-ui/react and cn, and merges the styles into your global CSS.
Terminal
```
npx shadcn@latest add @bevel/task-plan
```

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.

Copy task-plan.css into your styles.

styles/task-plan.css

/*
 * Task plan: an agent's plan written on a yellow legal pad. Builds on
 * bevel.css (bevel-ruled, pad, pens, pencil, motion).

}

[data-slot="task-plan"] {

Import the stylesheets after Tailwind in your global CSS, foundation first.

```
@import "./bevel.css";
@import "./task-plan.css";

Anatomy

Each part is its own component. Leave out the ones you don't need.

Anatomy

<TaskPlan>
  <TaskPlanHeader>
    <TaskPlanTitle />
    <TaskPlanProgress value={2} max={5} />
  </TaskPlanHeader>
  <TaskPlanSteps>
    <TaskPlanStep status="done" />
    <TaskPlanStep status="current" />
  </TaskPlanSteps>
</TaskPlan>

Parts

Part	Renders	What it does
TaskPlan	div	The pad. Every row sits on a rule.
TaskPlanProgress	Progress	value and max. Read as “2 of 5 done”; children replace the visible text.
TaskPlanSteps	ol	The steps, in order.
TaskPlanStep	li	status: done, current, pending, error or skipped, spoken before the step. The current step is marked aria-current. The tick draws itself when a step finishes.
