-# VS Code Extension Plan
-
-Chat UI sidebar panel for VS Code that connects to OpenCode backend.
-
-## Goals
-
-- Sidebar webview panel with OpenChamber chat UI
-- Reuse `@openchamber/ui` components (ChatView, stores, hooks)
-- Auto-detect VS Code theme (light/dark) and adapt
-- Use workspace folder as OpenCode directory
-- Support `@file` mentions via VS Code workspace API

-## Implementation Tasks
-
-### Phase 1: Extension Scaffold
-
-1. Create `packages/vscode/` directory structure
-2. Create `package.json` with extension manifest
-   - Sidebar view contribution
-   - Commands (new session)
-   - Configuration (API URL)
-3. Create `tsconfig.json` for extension host (Node.js)
-4. Create `tsconfig.webview.json` for webview (browser)
-5. Create `vite.config.ts` for webview bundling
-6. Add workspace reference in root `pnpm-workspace.yaml`
-
-### Phase 2: Extension Host
-
-1. `src/extension.ts` - activate/deactivate, register provider
-2. `src/ChatViewProvider.ts` - WebviewViewProvider implementation
-   - Generate HTML with CSP
-   - Handle webview lifecycle
-   - Pass workspace folder to webview
-3. `src/bridge.ts` - Message handler for webview requests
-   - `files:list` - list directory contents
-   - `files:search` - fuzzy file search
-   - `workspace:folder` - get workspace root
-4. `src/theme.ts` - Detect VS Code color theme kind
-
-### Phase 3: Webview Runtime
-
-1. `webview/main.tsx` - React entry point
-2. `webview/App.tsx` - Simplified app shell
-   - No MainLayout/Header/Sidebar
-   - Just ChatView + essential providers
-   - Theme sync with VS Code
-3. `webview/api/index.ts` - createVSCodeAPIs()
-   - RuntimeAPIs implementation
-   - IPC bridge to extension host
-4. `webview/api/files.ts` - FilesAPI via postMessage
-5. `webview/api/settings.ts` - SettingsAPI (theme from VS Code)
-
-### Phase 4: Theme Integration
-
-1. Listen to `vscode.window.onDidChangeActiveColorTheme`
-2. Map VS Code theme kind to OpenChamber light/dark
-3. Post theme changes to webview
-4. Apply theme CSS variables dynamically
-
-### Phase 5: File Context Support
-
-1. Implement `files:list` in extension host using `vscode.workspace.fs`
-2. Implement `files:search` using `vscode.workspace.findFiles`
-3. Wire up to ChatInput `@file` autocomplete
-
-### Phase 6: Build & Package
-
-1. Add build scripts to `packages/vscode/package.json`
-2. Add root-level scripts (`vscode:dev`, `vscode:build`, `vscode:package`)
-3. Configure `.vscodeignore` for clean packaging
-4. Test extension in VS Code Extension Host
-
-## Dependencies
-
-### Extension Host (Node.js)
-- `@types/vscode` - VS Code API types
-- `esbuild` - Bundle extension.ts
-
-### Webview (Browser)
-- `@openchamber/ui` (workspace) - Shared UI components
-- `vite` + `@vitejs/plugin-react` - Bundle React app
-- `@opencode-ai/sdk` - OpenCode API client
-
-## Extension Manifest Highlights

-```json
-{
-  "contributes": {
-    "views": {
-      "explorer": [{
-        "type": "webview",
-        "id": "openchamber.chatView",
-        "name": "OpenChamber"
-      }]
-    },
-    "commands": [{
-      "command": "openchamber.newSession",
-      "title": "OpenChamber: New Chat Session"
-    }],
-    "configuration": {
-      "properties": {
-        "openchamber.apiUrl": {
-          "type": "string",
-          "default": "http://localhost:47339"

-## Reused from @openchamber/ui
-
-| Module | Status |
-|--------|--------|
-| `components/chat/*` | Reuse all |
-| `components/views/ChatView` | Reuse |
-| `stores/useSessionStore` | Reuse |
-| `stores/useConfigStore` | Reuse |
-| `stores/useUIStore` | Partial (no sidebar state) |
-| `hooks/useEventStream` | Reuse |
-| `hooks/useMessageSync` | Reuse |
-| `lib/opencode/client` | Reuse |
-| `lib/theme/*` | Reuse (CSS generation) |
-| `components/layout/*` | Skip |
-| `components/views/GitView` | Skip |
-| `components/views/DiffView` | Skip |
-| `components/views/TerminalView` | Skip |
-
-## Not Needed (handled by VS Code)
-
-- Terminal API (VS Code integrated terminal)
-- Git API (VS Code SCM)
-- Notifications API (VS Code notifications)
-- Permissions API (VS Code handles sandbox)
-- Directory picker (workspace folder used)
-
-## Decisions
-
-- **View location**: Explorer sidebar
-- **Sidebar icon**: Reuse from `packages/web/public/` (tab icon)
-- **Marketplace icon**: Reuse from `packages/desktop/src-tauri/icons/app-icon-checkpoint.svg`
-- **Publisher**: `fedaykindev` (dev.azure.com/fedaykindev, artmore@protonmail.com)
