  fields: [
    { name: 'name', type: 'text', label: 'Your name', required: true },

## For agents

A worked example rendered live in the browser; the isolated preview frame (`/examples/preview/<id>/`) shows the same example without the site shell, and the example page next to it carries its code. The live parts run in the browser and are not in this Markdown; the operations below do the same work through the read-only MCP server at https://texuli.com/mcp (no sign-in; see https://texuli.com/auth.md).

MCP operations ([reference](https://github.com/DailybotHQ/texuli/blob/main/packages/tools/docs/ops.md#operations)):

- `example.search`: Find component examples.
- `component.get`: Read a component manifest.
