Chat Integration Summary

Date: February 20, 2026
Status: ✅ COMPLETE
Scope: Fill all instances where Chat components are required in officer-web

---

What Was Done

1. Chat Module Exports (Chat/index.tsx)

File: src/apps/officer-web/Screens/Dashboard/Chat/index.tsx

Changed From:

export {};

Changed To:

export { ChatPanel } from './ChatPanel';
export { EmbeddableChat, type Attachment } from './EmbeddableChat';
export { InputArea } from './InputArea';
export { Settings } from './Settings';
export { usePi } from './usePi';
export { ChatList } from './ChatList';

Impact: Now all Chat components are properly exported and available for import via @/Screens/Dashboard/Chat

---

2. ChatList Implementation (Chat/ChatList/index.tsx)

File: src/apps/officer-web/Screens/Dashboard/Chat/ChatList/index.tsx

Changed From: Placeholder that just displayed "ChatList"

Changed To: Fully functional component that:

• ✅ Displays all chat sessions from useChatSessions hook
• ✅ Shows session title, creation date, and model name
• ✅ Renders session count when empty
• ✅ Links to individual sessions via /chat/{sessionId}
• ✅ Uses duck-teal color scheme for consistency
• ✅ Shows message icon and metadata
• ✅ Responsive styling with hover states

Features:

export const ChatList = () => {
  const { sessions } = useChatSessions();

  if (sessions.length === 0) {
    return <empty-state>;
  }

  return (
    <div className="space-y-1.5 p-3">
      {sessions.map((session) => (
        <a href={`/chat/${session.id}`}>
          // Session item with title, date, model
        </a>
      ))}
    </div>
  );
};

Routes & Components

/chat                          → SessionListPage
  ├── SessionList (left panel)
  │   ├── ChatList (displays sessions)
  │   ├── Create Group button
  │   └── New Chat button
  │
  └── ChatDetailPanel (right panel)
      ├── SessionChat (existing sessions)
      │   ├── DetailBar (session info)
      │   └── EmbeddableChat
      │
      └── NewChat (new conversation)
          ├── DetailBar
          └── EmbeddableChat

/chat/new                     → SessionListPage with isNew=true
/chat/:sessionId              → SessionListPage with selected session

Workspace Registry

File: src/apps/officer-web/Screens/Dashboard/Workspaces/app-registry.tsx

Registered Apps:

appRegistry = {
  'chat': ChatWidget,                  // Main chat panel
  'chat-history': ChatHistory,         // Session management
  'chat-launcher': ChatLauncher,       // Quick launcher from home
  ...
}

Integration Points Verified

1. ChatDetailPanel (ChatHistory/ChatDetailPanel.tsx)

   • ✅ Uses usePi from Chat/usePi
   • ✅ Uses EmbeddableChat from Chat/EmbeddableChat
   • ✅ Uses useVisiblePiModels from state
   • ✅ Properly handles session and new chat flows

2. TaskRunnerModal (Files/Screen/TaskRunnerModal.tsx)

   • ✅ Uses usePi with taskInfo option
   • ✅ Uses EmbeddableChat with task context
   • ✅ Imports TaskInfo type from apps/Chat

3. CapabilityPage (CapabilityPage.tsx)

   • ✅ Uses usePi with replaceUrl=false
   • ✅ Uses EmbeddableChat for capability editing
   • ✅ Integrates with resource directory context

4. AutomationEditChat (Automation/AutomationEditChat.tsx)

   • ✅ Uses CapabilityChat from CapabilityPage
   • ✅ Handles delete and close operations
   • ✅ Integrates with automation workflow

5. App Registry (Workspaces/app-registry.tsx)

   • ✅ ChatWidget properly instantiated with usePi hook
   • ✅ Chat models passed via useVisiblePiModels
   • ✅ Registered as embeddable workspace app

Type Exports

All types properly exported from workspaces/apps/Chat/types.ts:

// Message Types
ChatMessage           // Frontend message representation
ServerMessage         // WebSocket protocol
Message              // Backend storage format

// Entity Types
SessionEntry         // Chat session metadata
GroupEntry           // Session group metadata
MessageCost          // Token/cost tracking
ModelOption          // AI model definition
TaskInfo             // Task execution context

// Legacy Types (for migration)
LegacyChatMessage
LegacySessionEntry
LegacyServerMessage

Exported Via:

• apps/Chat (workspaces/apps/Chat/index.ts)
• @/state/useModels (ModelOption)
• @/state/useChatSessions (SessionEntry, Message)
• @/state/useChatGroups (GroupEntry)

Next Steps (For Refactor)

Now that all Chat instances are filled and integrated, you can proceed with the major refactor:

1. Message Handlers Extraction: Move ServerMessage handlers from usePi to separate utilities
2. Streaming Abstraction: Create reusable hook for streaming text optimization
3. Component Consolidation: Consider merging redundant UI patterns
4. Model Selection Unification: Remove legacy OpenCodeModelPicker if still present
5. Type Safety Improvements: Convert panel channel to typed version
6. Feature Enhancement: Add drag-and-drop for session reordering
7. Performance Optimization: Consider virtual scrolling for large session lists
8. Search Enhancement: Implement full-text search across messages
