AI Studio Implementation Summary

Date: 2025-10-08 Status: ✅ Phase 1 Complete (AI Studio Tab - Loveable-style)

Overview

Successfully implemented the AI Studio Tab - a Loveable.dev-inspired split-screen interface for AI-assisted development. This is the first of three planned tab modalities for the CODITECT V5 frontend.

Three Tab Modalities Architecture

The V5 frontend now supports three distinct interaction modes:

1. AI Studio Tab ✅ COMPLETE

• Route: /ai-studio and /ai-studio/:sessionId
• Purpose: AI-assisted prototyping for novice users
• layout: Loveable-style split-screen (chat left, preview right)
• Features:
  • 4 llm workflow modes (Single, Parallel, Sequential, Consensus)
  • Live code preview with device size toggle (Mobile/Tablet/Desktop)
  • Real-time code execution in iframe sandbox
  • Multi-model selection (1-3 llms)
  • Code/Preview view toggle

2. workspace Tab 🔲 TODO

• Route: /workspace and /workspace/:sessionId
• Purpose: Traditional file-based development for power users
• layout: VS Code-like with activity bar, editor tabs, panels
• Source: Migrate from /src/frontend-original/src/components/workspace/unified-workspace.tsx

3. theia IDE Tab ✅ EXISTING

• Route: /ide and /ide/:sessionId
• Purpose: Full professional cloud IDE for advanced users
• layout: Eclipse theia embedded in iframe
• Features: Full VS Code compatibility, extensions, terminal

Integration

layout Component (/src/components/layout.tsx)

Updated to support tab modalities:

export type TabModality = 'workspace' | 'ai-studio' | 'theia' | null

interface layoutProps {
  // ...existing props
  tabModality?: TabModality
}

Behavior:

• tabModality="ai-studio" → Full-screen split view (no side panel)
• tabModality="workspace" → VS Code-like layout (with side panel)
• tabModality="theia" → Embedded theia IDE (with side panel)
• showIDE={false} → Regular page content (docs, login, etc.)

Routes (/src/app.tsx)

Added 6 new routes:

// AI Studio
/ai-studio              → AI Studio tab (default session)
/ai-studio/:sessionId   → AI Studio tab (specific session)

// workspace
/workspace              → workspace tab (default session)
/workspace/:sessionId   → workspace tab (specific session)

// theia (existing, now with explicit modality)
/ide                    → theia IDE (default session)
/ide/:sessionId         → theia IDE (specific session)

Key Features Implemented

1. 4 llm Workflow Modes

Single Mode

• One llm response at a time
• Simplest workflow for beginners

Parallel Mode

• 2-3 llms respond simultaneously
• Side-by-side comparison
• User can see different approaches

Sequential Mode

• Chain llms (llm1 → llm2)
• Output of first llm becomes input to second
• Refinement workflow

Consensus Mode

• Multiple llms vote on best answer
• Synthesized result shown
• Highest quality output

2. Live Code Preview

• Iframe Sandbox: sandbox="allow-scripts allow-same-origin"
• Device Sizes: Mobile (375px), Tablet (768px), Desktop (100%)
• Code/Preview Toggle: View source or rendered output
• Refresh: Reload preview
• Open in New Tab: Full-screen preview

3. Resizable Split-Screen

• Default: 40% chat, 60% preview
• Range: 25-75% (draggable divider)
• Smooth Transition: CSS transition on width change
• Visual Feedback: Divider highlights on hover

4. Model Selection

• Primary: Always shown (required)
• Secondary: Shown for multi-model modes (Parallel, Sequential, Consensus)
• Tertiary: Shown for Parallel/Consensus (optional)
• Filtering: Can't select same model twice
• Dynamic Loading: Fetches available models from LM Studio

Mock Data & TODO

Current Mock Implementations

The following are currently mocked and need real API integration:

1. ai-studio-store.ts → loadModels()

   // TODO: Replace with actual LM Studio API call
   const mockModels: llmModel[] = [
     { id: 'qwen/qwq-32b', name: 'QwQ 32B', provider: 'lmstudio', available: true },
     { id: 'meta-llama-3.3-70b', name: 'Meta Llama 3.3 70B', provider: 'lmstudio', available: true },
     // ...
   ]

2. ai-studio-store.ts → mockllmCall()

   // TODO: Replace with actual LM Studio HTTP call
   async function mockllmCall(modelId: string, message: string) {
     await new Promise(resolve => setTimeout(resolve, 1000)) // Simulate delay
     return { content: `Response from ${modelId}: ${message}` }
   }

3. preview-service.ts → transformJSXToJS()

   // TODO: Replace with Babel transformation for production
   // Current implementation is simplified and handles basic JSX only

Integration TODOs

• Connect loadModels() to LM Studio API: http://localhost:1234/v1/models
• Connect sendMessage() to LM Studio chat API: http://localhost:1234/v1/chat/completions
• Add error handling for offline LM Studio
• Add retry logic for failed llm calls
• Add rate limiting for llm requests
• Add Babel transformer for JSX → JS (production)
• Add syntax highlighting for code preview
• Add export functionality (download generated code)
• Add session persistence to FoundationDB

Testing Instructions

Local Development

1. Start the development server:

   cd /workspace/PROJECTS/t2
   npm run dev

2. Access AI Studio tab:

   http://localhost:5173/ai-studio

3. Test workflow modes:

   • Select "Single" mode → Enter prompt → Check single response
   • Select "Parallel" mode → Select 2-3 models → Enter prompt → Check multiple responses
   • Select "Sequential" mode → Select 2 models → Enter prompt → Check chained output
   • Select "Consensus" mode → Select 2-3 models → Enter prompt → Check synthesized result

4. Test preview panel:

   • Ask llm: "Build a React component with a button"
   • Check code appears in preview panel
   • Toggle device sizes (Mobile/Tablet/Desktop)
   • Toggle Code/Preview views
   • Test Refresh and "Open in new tab"

5. Test resizable panels:

   • Drag divider left/right
   • Verify chat panel stays within 25-75% range

Expected Behavior

✅ What Should Work:

• Route navigation (/ai-studio)
• UI rendering (split-screen layout)
• Workflow mode selection
• Model dropdowns (1-3 models based on mode)
• Message input/display
• Device size toggles
• Code/Preview toggle
• Panel resizing

⚠️ What Won't Work Yet (mocked):

• Actual llm responses (returns mock data)
• Model availability (shows hardcoded list)
• Code execution (basic iframe only)
• Session persistence (in-memory only)

Next Steps

Phase 8: Testing (Current)

• Run local development server
• Test all workflow modes
• Test preview panel features
• Test device size toggles
• Verify responsive layout

Phase 9: workspace Tab (Next)

• Copy V4 Unifiedworkspace components
• Adapt to V5 routing/layout
• Integrate with aiStudioStore (reuse session logic)
• Test multi-session tabs

Phase 10: LM Studio Integration

• Implement real loadModels() API call
• Implement real sendMessage() API call
• Add error handling
• Add loading states
• Test with actual llm responses

Phase 11: Production Readiness

• Add Babel transformer for JSX
• Add syntax highlighting
• Add export functionality
• Add session persistence to FoundationDB
• Add rate limiting
• Add comprehensive error handling

Architecture Decisions

1. Zustand for State Management

• Why: Lightweight, TypeScript-friendly, easy persistence
• Alternative considered: Redux (too complex for this use case)

2. Iframe for Preview

• Why: Sandboxed execution, prevents XSS, isolated styles
• Alternative considered: Shadow DOM (less isolation)

3. Mock llm Calls

• Why: Allows frontend development without backend dependency
• Plan: Replace with real API calls in Phase 10

4. No Side Panel in AI Studio

• Why: Loveable-style focuses on full-screen chat experience
• Tradeoff: Can't access sessions/models sidebar (use Header instead)

5. Resizable Panels (25-75% range)

• Why: Prevents panels from becoming unusable
• User Control: Still offers significant flexibility

Known Limitations

1. JSX Transformation: Simplified implementation, doesn't handle complex JSX

   • Impact: Advanced React components won't preview correctly
   • Mitigation: Add Babel transformer in Phase 11

2. Mock llm Responses: Not real AI responses

   • Impact: Can't test actual llm quality
   • Mitigation: Integrate LM Studio API in Phase 10

3. No Session Persistence: Sessions lost on page reload

   • Impact: User loses conversation history
   • Mitigation: Add FoundationDB persistence in Phase 11

4. No Export Functionality: Can't download generated code

   • Impact: Users must copy-paste
   • Mitigation: Add export button in Phase 11

5. No Syntax Highlighting: Code shown as plain text

   • Impact: Less readable code preview
   • Mitigation: Add Monaco editor or Prism.js in Phase 11
