+## React 19 UI Standards
+
+### Component Architecture
+
+#### Functional Components with Hooks
+```typescript
+import React, { useState, useEffect } from 'react';
+import { cn } from '@/lib/utils';
+
+interface MyComponentProps {
+  title: string;
+  onAction?: () => void;
+  className?: string;
+}
+
+export function MyComponent({ title, onAction, className }: MyComponentProps): JSX.Element {
+  const [isLoading, setIsLoading] = useState(false);
+
+  useEffect(() => {
+    // Side effects
+  }, []);
+
+  return (
+    <div className={cn('p-4 rounded-lg', className)}>
+      <h2 className="text-lg font-semibold">{title}</h2>
+      {isLoading ? (
+        <div>Loading...</div>
+      ) : (
+        <button onClick={onAction}>Action</button>
+      )}
+    </div>
+  );
+}
+```
+
+### UI Library Standards (shadcn/ui)
+
+#### Component Usage
+- Use shadcn/ui components as base building blocks
+- Customize with Tailwind CSS classes
+- Maintain consistent design tokens
+- Support dark mode out of the box
+
+```typescript
+import { Button } from '@/components/ui/button';
+import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
+
+export function SettingsPage(): JSX.Element {
+  return (
+    <Card>
+      <CardHeader>
+        <CardTitle>Settings</CardTitle>
+      </CardHeader>
+      <CardContent>
+        <Button variant="default">Save Changes</Button>
+      </CardContent>
+    </Card>
+  );
+}
+```
+
+### State Management
+
+#### TanStack Query for Server State
+```typescript
+import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
+import { getProfiles, updateProfile } from '@/lib/api';
+
+export function useProfiles() {
+  return useQuery({
+    queryKey: ['profiles'],
+    queryFn: getProfiles,
+    staleTime: 5 * 60 * 1000, // 5 minutes
+  });
+}
+
+export function useUpdateProfile() {
+  const queryClient = useQueryClient();
+
+  return useMutation({
+    mutationFn: updateProfile,
+    onSuccess: () => {
+      queryClient.invalidateQueries({ queryKey: ['profiles'] });
+    },
+  });
+}
+```
+
+#### Local State with useState
+- Use useState for simple component state
+- Use useReducer for complex state logic
+- Consider Zustand for global state (if needed)
+
+### Vite Configuration
+
+#### Build Settings (vite.config.ts)
+```typescript
+import { defineConfig } from 'vite';
+import react from '@vitejs/plugin-react';
+import path from 'path';
+
+export default defineConfig({
+  plugins: [react()],
+  resolve: {
+    alias: {
+      '@': path.resolve(__dirname, './src'),
+    },
+  },
+  build: {
+    outDir: 'dist',
+    sourcemap: true,
+    rollupOptions: {
+      output: {
+        manualChunks: {
+          vendor: ['react', 'react-dom'],
+          ui: ['@radix-ui/react-dialog', '@radix-ui/react-dropdown-menu'],
+        },
+      },
+    },
+  },
+  server: {
+    port: 3000,
+    proxy: {
+      '/api': {
+        target: 'http://localhost:8080',
+        changeOrigin: true,
+      },
+    },
+  },
+});
+```
+
+### Performance Guidelines
+
+#### Code Splitting
+- Lazy load routes with React.lazy()
+- Dynamic imports for heavy components
+- Use Suspense boundaries for loading states
+
+```typescript
+import { lazy, Suspense } from 'react';
+
+const SettingsPage = lazy(() => import('@/pages/settings'));
+
+function App() {
+  return (
+    <Suspense fallback={<div>Loading...</div>}>
+      <SettingsPage />
+    </Suspense>
+  );
+}
+```
+
+#### Optimization
+- Use React.memo() for expensive components
+- Implement virtual scrolling for long lists
+- Optimize re-renders with useMemo() and useCallback()
+
+### WebSocket Integration
+
+#### Real-time Updates
+```typescript
+import { useEffect, useState } from 'react';
+
+export function useWebSocket(url: string) {
+  const [data, setData] = useState<any>(null);
+  const [isConnected, setIsConnected] = useState(false);
+
+  useEffect(() => {
+    const ws = new WebSocket(url);
+
+    ws.onopen = () => setIsConnected(true);
+    ws.onclose = () => setIsConnected(false);
+    ws.onmessage = (event) => setData(JSON.parse(event.data));
+
+    return () => ws.close();
+  }, [url]);
+
+  return { data, isConnected };
+}
+```
+
+### Testing Standards
+
+#### Vitest Configuration
+```typescript
+import { defineConfig } from 'vitest/config';
+import react from '@vitejs/plugin-react';
+
+export default defineConfig({
+  plugins: [react()],
+  test: {
+    environment: 'jsdom',
+    setupFiles: ['./src/test/setup.ts'],
+  },
+});
+```
+
+#### Component Testing
+```typescript
+import { render, screen, fireEvent } from '@testing-library/react';
+import { Button } from '@/components/ui/button';
+
+describe('Button', () => {
+  it('renders correctly', () => {
+    render(<Button>Click me</Button>);
+    expect(screen.getByRole('button')).toBeInTheDocument();
+  });
+
+  it('handles click events', () => {
+    const handleClick = vi.fn();
+    render(<Button onClick={handleClick}>Click me</Button>);
+
+    fireEvent.click(screen.getByRole('button'));
+    expect(handleClick).toHaveBeenCalledTimes(1);
+  });
+});
+```

-
-## Core Components (Phase 05 Complete - 2025-12-01 | UI Phase 1 + Listr2)
-
-### 1. Main Entry Point (`src/ccs.ts` - 593 lines, 44.6% reduction)
-
-**Role**: Central orchestrator with **modular command routing** (Phase 02 enhanced)
-
-**Key Functions**:
-- `execClaude(claudeCli, args, envVars)`: Unified spawn logic (Windows shell detection)
-- `execClaudeWithProxy(claudeCli, profile, args)`: GLMT proxy lifecycle
-- `main()`: Profile routing + delegation detection (-p flag) + **command routing to modular handlers**
-
-**Phase 02 Modular Enhancements**:
-- **Command Routing**: Delegates to 6 specialized command handlers
-- **Main File Focus**: Now contains only routing logic + profile detection + GLMT proxy
-- **Maintainability**: Single responsibility principle applied to all commands
-- **Testing Independence**: Each command handler can be unit tested in isolation
-
-**v4.x Enhancements**:
-- Delegation detection: `-p` flag routes to DelegationHandler
-- Stream-JSON output support for real-time tool tracking
-- Shell completion installation (`--shell-completion`)
-- Update checking and CCS sync commands
-- Enhanced version display with API key validation
-
-**Architecture Flow**:
-```javascript
-// Delegation path (v4.0+)
-if (args.includes('-p') || args.includes('--prompt')) {
-  const { DelegationHandler } = require('./delegation/delegation-handler');
-  const handler = new DelegationHandler();
-  await handler.route(args);
-}
-
-// Settings profile (glm, kimi, glmt)
-const expandedSettingsPath = getSettingsPath(profileInfo.name);
-if (profileInfo.name === 'glmt') {
-  await execClaudeWithProxy(claudeCli, 'glmt', remainingArgs);
-} else {
-  execClaude(claudeCli, ['--settings', expandedSettingsPath, ...remainingArgs]);
-}
-
-// Account profile (work, personal)
-const instancePath = instanceMgr.ensureInstance(profileInfo.name);
-registry.touchProfile(profileInfo.name);
-const envVars = { CLAUDE_CONFIG_DIR: instancePath };
-execClaude(claudeCli, remainingArgs, envVars);

+### React Dashboard (ui/)
+
+**Technology Stack**:
+- React 19 with TypeScript
+- Vite for fast development and building
+- shadcn/ui component library (Radix UI + Tailwind)
+- TanStack Query for server state
+- Real-time WebSocket integration
+- Dark mode support
+
+**Key Pages**:
+- Dashboard: Overview and status
+- API Profiles: Model configuration
+- CLIProxy: OAuth provider setup
+- Accounts: Account management
+- Health: System diagnostics
+- Settings: Configuration
+- Shared: Data sharing management
 
 **Components**:
-- **version-command.ts** (3.0KB): Version display with build information and platform details
-- **help-command.ts** (4.9KB): Comprehensive help system with dynamic profile listings
-- **install-command.ts** (957B): Installation and uninstallation workflows
-- **doctor-command.ts** (415B): System diagnostics and health checks
-- **sync-command.ts** (1.0KB): Configuration synchronization and symlink repair
-- **shell-completion-command.ts** (2.1KB): Shell completion installation for 4 shells
-- **update-command.ts** (2.1KB): Update management with force reinstall support (Phase 2 implementation)
-
-**Phase 02 Benefits**:
-- **Single Responsibility**: Each command has focused, dedicated module
-- **Code Navigation**: Developers can quickly locate specific command logic
-- **Testing Independence**: Command handlers can be unit tested in isolation
-- **Parallel Development**: Multiple developers can work on different commands simultaneously
-- **Future Extension**: New commands can be added without modifying main orchestrator
-
-**Command Handler Interface**:
-```typescript
-interface CommandHandler {
-  handle(args: string[]): Promise<void>;
-  requiresProfile?: boolean;
-  description?: string;
-}
-```
-
-**New Utility Modules** (`src/utils/` - Phase 02):
-- **shell-executor.ts** (1.5KB): Cross-platform shell command execution with process management
-- **package-manager-detector.ts** (3.8KB): Package manager detection (npm, yarn, pnpm, bun)
-
-#### Phase 2 Implementation Details (Update Command)
-
-**Force Reinstall Feature (Phase 2)**:
-- **Purpose**: Allows users to bypass update checks and force reinstall from target channel
-- **Implementation**: Added `force` and `beta` flags to `UpdateOptions` interface
-- **Behavior**:
-  - When `force=true`: Skips version comparison and cache validation
-  - Installs directly from `latest` or `dev` tag based on `--beta` flag
-  - Automatically clears package manager cache before reinstalling
-  - Supports both npm and direct installation methods (with limitations)
-- **Error Handling**: Graceful fallback for direct install + beta flag combination
-
-**Key Functions**:
-- `handleUpdateCommand(options)`: Main entry point with flag parsing
-- `performNpmUpdate(targetTag, isReinstall)`: Handles npm-based updates with cache clearing
-- `performDirectUpdate()`: Handles installer-based updates (force only)
-- `handleDirectBetaNotSupported()`: Clear error messaging for unsupported combinations
-
-### 3. Delegation System (`src/delegation/` - ~1,200 lines, Phase 5 Enhanced)
-
-**New in v4.0**: Complete delegation subsystem; **Phase 5 Enhanced** with UI layer & Listr2
-
-**Components**:
-- **delegation-handler.ts** (~300 lines): Routes `-p` commands, validates profiles; async formatting
-- **headless-executor.ts** (~400 lines): Executes Claude CLI in headless mode with stream-JSON; UI progress
-- **session-manager.ts** (~200 lines): Manages delegation session persistence (continue support)
-- **result-formatter.ts** (~150 lines): **Async formatting** with styled boxes and tables (Phase 5)
-- **settings-parser.ts** (~150 lines): Parses profile settings for validation
-
-**Key Features**:
-- **Stream-JSON output**: Real-time tool visibility (`--output-format stream-json --verbose`)
-- **Session continuation**: `ccs glm:continue -p "follow-up"` resumes last session
-- **Tool tracking**: Shows file paths, commands, patterns as they execute
-- **Signal handling**: Ctrl+C kills child processes properly
-- **Cost tracking**: USD cost display per delegation
-- **13 Claude Code tools** supported: Bash, Read, Write, Edit, Glob, Grep, NotebookEdit, SlashCommand, TodoWrite, etc.
-- **Phase 5 Enhancements**:
-  - **Styled output**: UI layer integration for semantic boxes and tables
-  - **Async formatting**: Result formatter now fully async with ui.init() call
-  - **Listr2 integration**: Optional task list progress in TTY mode
-  - **Fallback chain**: Graceful degradation for non-TTY/CI environments
-
-**Delegation Flow**:
-```
-User: ccs glm -p "add tests"
-  ↓
-DelegationHandler: Parse args, validate profile
-  ↓
-HeadlessExecutor: Spawn Claude CLI with --output-format stream-json --verbose
-  ↓
-Stream parser: Extract [Tool] lines, format in real-time
-  ↓
-SessionManager: Save session ID for :continue
-  ↓
-ResultFormatter: Display cost, duration, exit code
-```
-
-### 3. Auth System (`bin/auth/` - ~800 lines)

-- **auth-commands.js** (~400 lines): CLI handlers for auth subcommands
-- **profile-detector.js** (~150 lines): Profile type routing (settings vs account)
-- **profile-registry.js** (~250 lines): Metadata management (profiles.json)
-
-**v4.x Status**: Core logic stable, focus shifted to delegation
-
-**Profile Creation Flow (v3.0+)**:
-```bash
-# Create profile (prompts login)
-ccs auth create work  # Opens Claude, auto-prompts OAuth
-# Use directly (credentials in instance)
-ccs work "task"
-```
-
-### 4. GLMT System (`bin/glmt/` - ~900 lines)
-
-**Role**: GLM with thinking mode via embedded proxy

-
-### 7. CCS .claude/ Directory (`/.claude/` - packaged with npm)
-
-**New in v4.1**: Selective symlink approach
-
-**Structure**:
-```

-```
-
-**Symlink Strategy** (v4.1):
-- **Source**: `~/.ccs/.claude/` (copied from npm package)
-- **Target**: `~/.claude/commands/ccs@`, `~/.claude/skills/ccs-delegation@`
-- **Selective**: Only CCS items symlinked, doesn't overwrite user's other commands/skills
-- **Windows**: Falls back to copying if Developer Mode not enabled
-
-**Installation Flow** (v4.1.1):
-1. `npm install -g @kaitranntt/ccs`
-2. Postinstall: ClaudeDirInstaller copies `.claude/` → `~/.ccs/.claude/`
-3. Postinstall: ClaudeSymlinkManager creates selective symlinks → `~/.claude/`
-4. User can now use `/ccs` (auto-select) and `/ccs:continue` commands

-## Key Features (v4.5.0 - Phase 02 Complete, UI Phase 1)
-
-### 0. Central UI Abstraction Layer (UI Phase 1 - 2025-12-01, Phase 5 Complete)
-- **New Module**: src/utils/ui.ts (5.2KB) - Semantic, TTY-aware CLI styling
-- **Dependencies**: chalk@5.6.2, boxen@8.0.1, gradient-string@3.0.0, cli-table3@0.6.5, ora@5.4.1, listr2@8.0.0
-- **Features**:
-  - Semantic color system (success, error, warning, info, dim, primary, secondary, command, path)
-  - ASCII-only status indicators ([OK], [X], [!], [i]) - NO EMOJIS per CLAUDE.md
-  - TTY-aware output (respects NO_COLOR, FORCE_COLOR env vars)
-  - Box rendering (with fallback ASCII renderer)
-  - Table rendering via cli-table3
-  - Spinner/progress (ora wrapper with fallback)
-  - Section headers with optional gradient
-  - **Listr2 task lists** (Phase 5 NEW) - intelligent renderer selection:
-    - TTY mode: Default renderer with subtask hierarchy
-    - Non-TTY/CI: Simple renderer for clean output
-    - Claude Code detection: Automatic fallback for tool context
-  - Lazy loading of ESM modules for CommonJS compatibility
-- **Type Support**: SemanticColor, BoxOptions, TableOptions, SpinnerOptions, SpinnerController, TaskItem, TaskListOptions
-- **Compliance**: Strict CLAUDE.md adherence (no emojis, TTY-aware, NO_COLOR respect)
-- **Fallback Architecture**: Works in non-TTY environments with graceful degradation
-- **Claude Code Integration** (Phase 5): `isClaudeCodeContext()` detection for adaptive UI rendering
-
-### 1. npm-First Installation (Phase 02 - 2025-11-28)
-- **Recommended method**: All users directed to npm installation
-- **Native installer deprecation**: curl/irm scripts auto-redirect to npm
-- **Cross-platform parity**: Single installation method across macOS/Linux/Windows
-- **Easy updates**: `npm install -g @kaitranntt/ccs` (version pinning supported)
-- **Bootstrap installers**: Replaced shell scripts with Node.js-based installation
-
-### 2. AI-Powered Delegation (v4.0+)
-- **Headless execution**: `ccs glm -p "task"` runs without interactive UI
-- **Stream-JSON output**: Real-time tool visibility (`[Tool] Write: file.js`)
-- **Session continuation**: `ccs glm:continue -p "follow-up"` resumes last session
-- **Cost tracking**: USD cost display per delegation
-- **Signal handling**: Proper Ctrl+C cleanup
-- **13 tools supported**: Comprehensive Claude Code tool coverage
-
-### 3. Selective .claude/ Symlinking (v4.1)
-- **Package-provided**: `.claude/` ships with npm, copied to `~/.ccs/.claude/`
-- **Selective symlinks**: Only CCS items linked to `~/.claude/`
-- **Non-invasive**: Doesn't overwrite user's commands/skills
-- **Windows support**: Falls back to copying if symlinks unavailable
-- **Auto-sync**: `ccs sync` re-creates symlinks
-
-### 4. Enhanced Shell Completion (v4.1.4)
-- **4 shells**: bash, zsh, fish, PowerShell
-- **Color-coded**: Commands vs descriptions
-- **Categorized**: Model profiles, account profiles, flags
-- **Auto-install**: `ccs --shell-completion` or `ccs -sc`
-
-### 5. Comprehensive Diagnostics (v4.1+)
-- **ccs doctor**: Health check for installation, configs, symlinks, delegation
-- **ccs sync**: Re-sync delegation commands and skills
-- **ccs update**: Check for updates (v4.1+)
-
-### 6. Text-Only Output (Phase 02 - CLAUDE.md Compliance)
-- **ASCII indicators only**: [OK], [!], [X], [i] (no emoji)
-- **TTY-aware colors**: Respects NO_COLOR environment variable
-- **Consistent formatting**: Box borders for errors using ╔═╗║╚╝
-- **Cross-platform consistency**: Identical output on all shells
-
-### 7. GLMT Thinking Mode (v3.x, stable experimental)
-- **Embedded proxy**: HTTP proxy on localhost:random
-- **Format conversion**: Anthropic ↔ OpenAI
-- **Reasoning injection**: Force English, thinking prompts
-- **Debug logging**: `CCS_DEBUG_LOG=1` writes to `~/.ccs/logs/`
-
-## Breaking Changes
-
-### v3.0 → v4.0
-- **No breaking changes**: v4.0 purely additive (delegation features)
-- **New dependencies**: None (all Node.js built-ins)
-- **Migration**: Automatic via postinstall
-
-### v2.x → v3.0 (Historical)
-- Command renamed: `ccs auth save` → `ccs auth create`
-- Schema changed: Removed `vault`, `subscription`, `email` fields
-- Migration required: Users must recreate profiles
-
