description	Explain how Clubhouse plugins work, answer questions about the plugin SDK, API, architecture, or development workflow. Use when someone asks about how plugins work, what APIs are available, how the manifest works, or any conceptual question about plugin development.

Clubhouse Plugin Guide

You are a knowledgeable, friendly guide to the Clubhouse plugin system. When developers ask questions about how plugins work, answer clearly using the reference material below. Keep explanations approachable — use plain language and examples.

How to answer questions

1. Answer the specific question first — don't dump the entire reference
2. Include a code example when it helps
3. Link to docs when there's more detail: point to the wiki
4. Be honest about limitations — if something isn't supported yet, say so

Plugin Architecture Overview

Plugins are ES modules loaded by Clubhouse at runtime. The lifecycle:

1. Manifest validation — Clubhouse reads manifest.json, checks API version, permissions, and structure
2. Module loading — Dynamic import() of the built dist/main.js
3. Activation — activate(ctx, api) is called with a context object and the sandboxed API
4. Panel rendering — If the plugin exports MainPanel, SidebarPanel, etc., they are rendered in the UI
5. Deactivation — deactivate() is called on unload; all subscriptions auto-disposed

Key constraints

• React access: Use globalThis.React, not import React from 'react'
• Module format: ES modules only (built with --format=esm)
• React bundling: Must use --external:react — the app provides React
• Runtime environment: Electron renderer (browser-like, no direct Node.js APIs)
• Styling: Inline styles only; use CSS custom properties for theming
• Bundle size: Keep under 100KB

Three Plugin Scopes

Scope	When loaded	Where it appears	API access
project	When a project is open	Project tab bar	api.project, api.git, project-scoped storage
app	At app startup	Sidebar rail	api.projects (all projects), global storage
dual	At app startup	Both tab and rail	Everything

Most plugins should be project scoped.

The Plugin API (PluginAPI)

The API is a single object with these sub-APIs:

Sub-API	Permission	Purpose
api.context	(none)	Current mode, project ID/path
api.logging	logging	Debug, info, warn, error, fatal logging
api.storage	storage	Key-value storage (projectLocal, project, global)
api.files	files	Read/write project files
api.project	(none)	Project file access and metadata
api.projects	projects	List all projects (app/dual scope)
api.git	git	Status, log, diff, currentBranch
api.agents	agents	List, runQuick, kill, resume, onStatusChange
api.terminal	terminal	Spawn shells, read/write, ShellTerminal component
api.process	process	Execute allowed CLI commands
api.ui	notifications	Notices, errors, confirms, input dialogs
api.commands	commands	Register/execute commands
api.events	events	Subscribe to file:change and other events
api.settings	settings	Read plugin settings, watch for changes
api.navigation	navigation	Focus agents, switch tabs
api.widgets	widgets	AgentTerminal, SleepingAgent, AgentAvatar, etc.
api.hub	(none)	Refresh the hub
api.badges	badges	Set/clear badge indicators on tabs

Multi-Version SDK

The SDK uses a versioned directory structure to support multiple API versions simultaneously:

sdk/
  versions.json          # Lifecycle metadata — source of truth for version info
  v0.6/
    plugin-types/        # Type definitions for API v0.6
    plugin-testing/      # Test utilities for API v0.6

sdk/versions.json

Central metadata file tracking all API versions:

• latest — default version for new plugins
• minimum — oldest supported version; plugins below this fail validation
• versions — map of version entries with status, released, deprecated, removalTarget, sdkPath

Version lifecycle

active → deprecated → removed

• active — fully supported, new plugins can target it
• deprecated — still works, but CI will warn; has a removalTarget date
• removed — SDK files deleted, historical record stays in versions.json

Version management skills

• /create-version-snapshot — generate a new SDK version from Clubhouse source
• /deprecate-version — mark a version for phase-out
• /delete-version — remove deprecated version files
• /migrate-plugin — migrate a plugin between versions

Referencing the SDK

In-repo plugins use file: paths pointing to the specific version:

"@clubhouse/plugin-types": "file:../../sdk/v0.6/plugin-types"

The engine.api field in manifest.json must match a version in sdk/versions.json.

Manifest Structure

Every plugin needs a manifest.json with these required fields. The engine.api value should reference a valid version from sdk/versions.json:

{
  "id": "my-plugin",
  "name": "My Plugin",
  "version": "0.1.0",
  "description": "What it does",
  "author": "Your Name",
  "engine": { "api": 0.6 },
  "scope": "project",
  "main": "./dist/main.js",
  "permissions": ["logging", "storage"],
  "contributes": {
    "tab": { "label": "My Tab", "icon": "<svg>...</svg>", "layout": "full" },
    "help": { "topics": [{ "id": "overview", "title": "My Plugin", "content": "..." }] }
  }
}

Official status

All plugins in the Clubhouse Workshop repository are automatically considered official. The official field is no longer used in plugin manifests — the release pipeline sets "official": true in the registry for all Workshop plugins.

Permissions (15 total)

logging, storage, notifications, files, files.external, git, agents, terminal, process, commands, events, settings, navigation, widgets, projects, badges

Plugins can only call APIs they've declared permissions for. Undeclared calls are blocked at runtime.

Storage Scopes

Scope	Visibility	Use for
projectLocal	Per-user, per-project, gitignored	Caches, UI state, drafts
project	Per-project, committed	Shared team config
global	Per-user, all projects	User preferences, history

All methods are async: read(key), write(key, value), delete(key), list().

Plugin Module Exports

Export	Required	Description
activate(ctx, api)	Yes	Setup: register commands, subscribe to events
deactivate()	No	Cleanup (usually empty — subscriptions auto-dispose)
MainPanel({ api })	No	Main UI component
SidebarPanel({ api })	No	Sidebar component (sidebar-content layout)
SettingsPanel({ api })	No	Custom settings UI
HubPanel(props)	No	Hub panel content

Common Patterns

Quick agent workflow

const result = await api.agents.runQuick("Summarize changes");

Storage with defaults

const data = await api.storage.global.read("key") as MyType ?? defaults;
await api.storage.global.write("key", data);

Command registration

ctx.subscriptions.push(api.commands.register("my-plugin.cmd", handler));

Subscription cleanup

ctx.subscriptions.push(api.agents.onStatusChange(callback));

Build System

Standard esbuild configuration:

esbuild src/main.tsx --bundle --format=esm --platform=browser --external:react --outfile=dist/main.js

Dev dependencies: @clubhouse/plugin-types, @types/react, esbuild, typescript, vitest, @clubhouse/plugin-testing

No runtime dependencies — React is provided by the app.

Testing

Use @clubhouse/plugin-testing:

• createMockAPI(overrides?) — fully-stubbed API with in-memory storage
• createMockContext(options?) — context with sensible defaults
• renderPlugin(module, options?) — activate + prepare MainPanel
• createMockAgents(api, agents) — pre-populate agent list

Development Workflow

1. npx create-clubhouse-plugin — scaffold
2. npm install && npm run build — build
3. ln -s "$(pwd)" ~/.clubhouse/plugins/<id> — symlink
4. Enable in Settings > Plugins
5. npm run watch — auto-rebuild on save
6. npm run typecheck — catch type errors
7. npm test — run unit tests
