Phase 5: Frontend Complete - Ready for Testing & Backend Integration

🎉 Phase 5 Frontend Status: COMPLETE

We've successfully implemented the frontend portion of Phase 5, which establishes the complete data flow from the collaborative document editor to the chat system with full document context.

✅ What's Working Now

1. Document Context Capture

• When a user clicks "Ask Goose" in the document editor, the full document context is captured
• Context includes:
  • Document ID
  • Full document content
  • Selected text (if any) with position information
  • Timestamp

2. Chat Integration

• Document context is stored in ChatInput component state
• Chat input is automatically populated with a contextual prompt
• User can modify the prompt before sending

3. Message Submission with Metadata

• When the user sends a message, document context is included in the payload
• Message structure:

  {
    value: string,  // The actual message text
    documentContext?: {
      docId: string,
      content: string,
      selection?: { from: number, to: number, text: string },
      timestamp: number
    }
  }
  

4. State Management

• Document context is automatically cleared after message submission
• Prevents stale context from being included in subsequent messages
• Backward compatible - messages without document context work normally

🧪 How to Test Right Now

Test 1: Basic Document Context Flow

# 1. Start the application
cd /Users/spencermartin/Desktop/goose
source bin/activate-hermit
cd ui/desktop
npm run dev

# 2. In the application:
# - Click the "+" button
# - Select "New Document"
# - Type some content: "Hello World! This is a test document."
# - Click "Ask Goose" button
# - Check browser console (F12) for: "📄 Document context stored for message submission"
# - Chat input should be populated with: "I need help with this document: ..."

Test 2: Verify Context in Message

# 1. Continue from Test 1
# 2. Before sending, open browser console
# 3. Type a message: "Make this text bold"
# 4. Click Send
# 5. Check console for: "📄 Including document context in message: {...}"
# 6. You should see the full document context object logged

Test 3: Selection Context

# 1. In the document editor, type: "The quick brown fox jumps over the lazy dog"
# 2. Select "quick brown fox"
# 3. Click "Ask Goose"
# 4. Check console - the documentContext should include:
#    selection: { from: 4, to: 19, text: "quick brown fox" }

Test 4: API Direct Testing

// Open browser console and run:

// 1. Check if editor is registered
console.log(window.gooseEditors);

// 2. Get the document ID (replace 'doc-xxx' with actual ID from console)
const docId = Object.keys(window.gooseEditors)[0];

// 3. Test editor methods
window.gooseEditors[docId].appendText("\n\nThis was added via API!");
window.gooseEditors[docId].insertText("INSERTED TEXT ", 0);
window.gooseEditors[docId].formatText(0, 13, { bold: true });

// 4. Get content
console.log(window.gooseEditors[docId].getContent());

🔧 Files Modified in Phase 5

Frontend (Complete ✅)

1. ui/desktop/src/components/ChatInput.tsx

   • Added documentContext state
   • Enhanced populate-chat-input event listener
   • Modified performSubmit to include context in message
   • Added context clearing after submission

2. ui/desktop/src/components/CollaborativeDocEditor.tsx (from previous phases)

   • Exposes window.gooseEditors[docId] API
   • Dispatches populate-chat-input event
   • Dispatches goose-doc-assist event
   • Visual feedback for Goose editing state

Backend (To Be Implemented 🔄)

1. Message Handler (Rust)

   • Parse documentContext from incoming messages
   • Pass context to AI agent

2. Tool Registration (Rust)

   • Register edit_document tool
   • Define tool parameters and actions

3. IPC Bridge (Electron)

   • Create execute-document-edit IPC handler
   • Execute JavaScript in renderer process

4. AI Prompt System (Rust/Python)

   • Enhance system prompt with document context
   • Include document content and selection info

🎯 Next Steps for Backend Team

Step 1: Verify Frontend Works

# Run the tests above to confirm frontend is working
# Check console logs for document context flow
# Test the window.gooseEditors API directly

Step 2: Identify Backend Entry Point

# Find where messages are received in the Rust backend
cd /Users/spencermartin/Desktop/goose/crates
rg "handleSubmit" -A 5
rg "message.*handler" -A 5

Step 3: Parse Document Context

// In the message handler, parse the documentContext field
struct MessagePayload {
    value: String,
    document_context: Option<DocumentContext>,
}

struct DocumentContext {
    doc_id: String,
    content: String,
    selection: Option<Selection>,
    timestamp: i64,
}

Step 4: Register Document Tool

// Register the edit_document tool for AI to call
fn register_document_tools() {
    register_tool("edit_document", |params| {
        // Execute JavaScript in renderer via IPC
        execute_document_edit(
            params.doc_id,
            params.action,
            params.args
        )
    });
}

Step 5: Create IPC Bridge

// In ui/desktop/src/main/index.ts
ipcMain.handle('execute-document-edit', async (event, docId, method, args) => {
  const window = BrowserWindow.getFocusedWindow();
  if (window) {
    return window.webContents.executeJavaScript(`
      (function() {
        const editor = window.gooseEditors['${docId}'];
        if (editor && typeof editor.${method} === 'function') {
          return editor.${method}(...${JSON.stringify(args)});
        }
        return { error: 'Editor not found' };
      })()
    `);
  }
});
