Components
PermissionPrompt
An explicit access request (sensors, location, camera, mic) — which MRBD apps must ask for before use. A gradient-plate icon, a clear title, the reason, and allow / deny actions.
Installation
npx @glasskit-ui/cli add permission-promptInstall the SDK (it provides GlassViewport, useDpad and the stylesheet), then copy these files into your project:
npm install @glasskit-ui/react// components/lib/utils.tsexport type ClassValue = string | number | null | undefined | false;/** * Join truthy class names. Dependency-free on purpose: the lens components * style via bespoke semantic classes (no conflicting Tailwind utilities to * de-dupe), so this needs no clsx/tailwind-merge and resolves from anywhere * the registry is vendored. */export function cn(...inputs: ClassValue[]): string { return inputs.filter(Boolean).join(" ");}/** * Accessible name from a free-form `label` prop: the label itself when it's a * plain string, otherwise undefined (a ReactNode can't become an aria-label). */export function stringLabel(label: unknown): string | undefined { return typeof label === "string" ? label : undefined;}// components/glasskit/permission-prompt.tsx"use client";import type { ReactNode } from "react";import { FocusScope } from "@glasskit-ui/react";import { cn } from "../lib/utils";/** * <PermissionPrompt> — an explicit access request (sensors, location, camera, * mic), which MRBD apps must ask for before use.

Prop
Type
Dictation
The voice-to-text surface (no keyboard on the lens — text is voice or Neural-Band handwriting): a live waveform + the running transcript. You own the recognition and feed transcript.
TextField
A text-entry surface. No keyboard (or microphone API) on the lens — a focusable field showing the value + a mic-style affordance; onActivate opens your own capture flow (picker UI, phone relay).
