everything-evenhub is an open-source Claude Code plugin that teaches Claude how to build for the Even G2 - the SDK, the display constraints, the simulator, packaging, all of it. Install once; describe what you want.

What is this?

Claude Code is Anthropic's command-line AI coding tool. Instead of pasting prompts into a chat window, Claude runs in your terminal, reads your files, writes code, and runs commands. Free to try, works with the same Claude account you may already use. More at claude.com/claude-code.

Out of the box, Claude Code knows nothing specific about the G2 platform. The plugin adds 13 skills covering the full development lifecycle:

Tier	Skills	Purpose
Tier 1 - One-click	quickstart, template, build-and-deploy	Scaffold a new app; package and publish
Tier 2 - Core dev	glasses-ui, handle-input, device-features, background-state, test-with-simulator, simulator-automation, font-measurement	Day-to-day coding tasks
Tier 3 - Reference	sdk-reference, cli-reference, design-guidelines	Look-up / deep-dive

Install

1. Install Claude Code - see claude.com/claude-code
2. In your terminal, add the marketplace:

   /plugin marketplace add even-realities/everything-evenhub

3. Install the plugin:

   /plugin install everything-evenhub

That's it - Claude picks up the skills on its own whenever your task mentions the G2.

Try it

In Claude Code:

Build me a hello-world app for the Even G2 glasses that shows "Hello, Even!" on the display.

Claude recognizes the request, invokes the quickstart skill, scaffolds the project, and walks you through running it in the simulator.

How it works

You don't have to teach Claude about the skills or memorize their names. Each skill is a markdown file with a short description; Claude reads those descriptions and picks the right one for what you asked. Behind the scenes, the same SDK docs and design guidelines you'll find elsewhere on this site - routed through Claude's context.

Lookup table for every skill - what it does, sample prompts, and how the skills chain. Definitions live in the open-source even-realities/everything-evenhub repo (skills/). The accordions below mirror that layout - click any skill to expand.

Tier 1 - one-click

quickstart - Scaffold a blank Even G2 app from scratch

Purpose: Scaffold a blank Even G2 app from scratch (Vite + TypeScript + @evenrealities/even_hub_sdk).

Trigger example: /quickstart my-weather-app or "Build me a new Even G2 app called stopwatch."

What it does: Creates a fresh Vite project and wires the SDK - not a curated example app.

Related: → template (when you want a starter instead of blank), build-and-deploy, glasses-ui

template - Scaffold from a curated starter via degit

Purpose: Scaffold from a curated starter in even-realities/evenhub-templates via degit - wiring included.

Trigger example: /template my-reader --text-heavy, /template --asr my-transcription-app, /template --image photo-frame, /template --minimal hello-glasses

What it does: Pulls minimal, asr, image, or text-heavy template; normalizes flags (--withasr, --reader, etc.); renames package.json / app.json; runs npm install.

Related: → quickstart (blank slate), build-and-deploy, font-measurement (for text-heavy pagination), Templates (manual flow without Claude)

build-and-deploy - Package and publish to Even Hub

Purpose: Package and publish your app to Even Hub.

Trigger example: /build-and-deploy or "Package my app and upload it to the dev portal."

What it does: Uses the Even Hub CLI to build the .ehpk and complete the deployment flow.

Related: → quickstart, template, cli-reference

Tier 2 - core development

glasses-ui - Build display UI (containers, text, images, lists)

Purpose: Build glasses display UI - containers, text, images, lists - for the Even G2 screen.

Trigger example: /glasses-ui "show a 3-item menu with a title bar"

What it does: Layout and components tuned to Even G2 display constraints.

Related: → handle-input, font-measurement, design-guidelines

handle-input - Touchpad gestures and ring input

Purpose: Handle touchpad gestures and ring input.

Trigger example: /handle-input "single press cycles screens, double press exits"

What it does: Wires listeners and handlers for supported inputs.

Related: → glasses-ui, background-state

device-features - Audio, IMU, device info, local storage

Purpose: Use hardware-facing capabilities - audio capture, IMU, device info, local storage, etc.

Trigger example: /device-features "toggle microphone recording on click"

What it does: Interfaces with the SDK for sensors, audio, and related APIs.

Related: → sdk-reference

background-state - Persist state across foreground / background

Purpose: Persist plugin state across phone background / foreground when the host uses headless WebView migration.

Trigger example: /background-state src/main.ts or "My app resets when the phone comes back from background."

What it does: Analyzes code and inserts setBackgroundState + onBackgroundRestore from @evenrealities/even_hub_sdk so mutable state survives __getStateSnapshot / __restoreState.

Related: → sdk-reference, handle-input

test-with-simulator - Run and debug in the simulator

Purpose: Run and debug the app in the Even Hub Simulator.

Trigger example: /test-with-simulator "debug my app with glow effect"

What it does: Launches the local simulator workflow for the current project.

Related: → simulator-automation

simulator-automation - Drive the simulator over HTTP

Purpose: Drive the simulator over its HTTP API - screenshots, input injection, console logs.

Trigger example: /simulator-automation "take a screenshot and verify text is displayed"

What it does: Automates simulator actions for repeatable checks.

Related: → test-with-simulator

font-measurement - Pixel-accurate text and list measurement

Purpose: Pixel-accurate text and list measurement aligned with LVGL firmware rendering.

Trigger example: /font-measurement "size a text container for a long paragraph with 8px padding"

What it does: Measurement utilities for layout that matches on-device text metrics.

Related: → glasses-ui

Tier 3 - reference

sdk-reference - Look up SDK APIs, types, patterns

Purpose: Look up Even Hub SDK APIs, types, and patterns.

Trigger example: /sdk-reference createStartUpPageContainer

What it does: Surfaces SDK documentation for the symbol or topic you name.

Related: → device-features, background-state

cli-reference - Look up Even Hub CLI commands and flags

Purpose: Look up Even Hub CLI commands and flags.

Trigger example: /cli-reference evenhub qr

What it does: Usage and examples for CLI tooling (evenhub, packaging, QR, etc.).

Related: → build-and-deploy

design-guidelines - Display constraints and UX best practices

Purpose: Even G2 display design constraints and UX best practices.

Trigger example: /design-guidelines settings screen with 5 options

What it does: Design specs and guidance for readable, consistent glasses UI.

Related: → glasses-ui

Harness testing

The plugin repo ships a harness runner that regression-tests skills with an AI agent. Example:

/harness quickstart

See harness/README.md for how to add tests for new skills.
