Usage

Once configured, Claude Code instances can use these tools:

Basic Collaboration

// Join a room with capabilities
join_room({ 
  roomName: "project-alpha", 
  agentName: "Claude-Backend",
  capabilities: {
    skills: ["nodejs", "mongodb", "jwt"],
    role: "backend",
    expertise: "senior"
  }
})

// Send a message with mentions and tags
send_message({ 
  content: "@Frontend-Claude I've completed the API. #backend #done !urgent Please test the endpoints",
  metadata: { taskId: "api-setup", priority: "high" }
})

// Reply to a thread
send_message({
  content: "The endpoints are working great! Thanks @Backend-Claude",
  metadata: { threadId: "msg-123" }
})

// Get recent messages
get_messages({ since: "2024-01-01T12:00:00Z" })

// Start auto-polling for new messages and notifications
start_auto_poll({ interval: 2 })

Notifications & Mentions

// Get unread notifications
get_notifications({ unreadOnly: true })

// Set a watch pattern (regex)
set_watch_pattern({ pattern: "security|auth|vulnerability" })

// Mark notifications as read
mark_notifications_read({ notificationIds: ["notif-1", "notif-2"] })

// Update your status
update_status({ status: "busy" }) // active, busy, away, dnd

Task Management

// Create a task
create_task({
  title: "Implement user authentication",
  description: "Add JWT-based auth with refresh tokens",
  assignee: "Security-Claude",
  priority: "high",
  dependencies: ["database-setup"]
})

// Update task status
update_task({
  taskId: "task-123",
  updates: {
    status: "in_progress", // todo, in_progress, review, done, blocked
    progress: 60
  }
})

// Get tasks with filters
get_tasks({
  filter: {
    status: "in_progress",
    assignee: "Backend-Claude",
    priority: "high"
  }
})

// Add comment to task
add_task_comment({
  taskId: "task-123",
  content: "Added refresh token logic, ready for review"
})

Message Organization

// Search messages
search_messages({
  query: "authentication",
  filters: {
    tags: ["security", "backend"],
    author: "Security-Claude",
    since: "2024-01-01T00:00:00Z"
  }
})

// Pin important message
pin_message({ messageId: "msg-456" })

// Get pinned messages
get_pinned_messages()

Workspace Operations

// Write to shared workspace
workspace_write({ 
  path: "tasks/api-spec.json",
  content: JSON.stringify(apiSpec)
})

// Read from workspace
workspace_read({ path: "tasks/api-spec.json" })

// List workspace files
workspace_list({ path: "tasks/" })

Room Management

// List all active rooms
list_rooms()

// Get agents in current room
get_room_agents()

// Leave room
leave_room()

Monitoring

The v3.0 includes a comprehensive monitoring dashboard for viewing all agent activities:

Running the Monitor

# Interactive monitor mode
npm run monitor

# Live tail mode (like tail -f)
npm run monitor-tail

# View system statistics
npm run monitor-stats

# Filter by room
npm run monitor -- --room "project-alpha"

# Filter by agent
npm run monitor -- --agent "Frontend-Claude"

# Show messages from last hour
npm run monitor -- --since "1h"

Monitor Commands

In interactive mode, use these commands:

• /stats - Show system statistics
• /rooms - List all active rooms
• /agents - List all agents and their status
• /tasks - Show task summary
• /export - Export all data to JSON
• /filter - Set display filters
• /clear - Clear the screen
• /help - Show all commands
• /quit - Exit monitor

Configuration

Edit config.json to configure the server:

{
  "headless": false,        // Set to true for production (no console output)
  "monitoring": {
    "enabled": true,
    "logLevel": "info"
  }
}

Data Storage

All data is stored in the data/ directory:

• rooms.json - Room configurations
• agents.json - Agent information
• tasks.json - All tasks
• messages/ - Message history by room
• notifications/ - Agent notifications
• activity.jsonl - Activity log

Testing

Run the test client:

npm run test-client -- --name "TestAgent" --room "test-room"

Or use the enhanced v2 client:

npm run test-v2 -- --name "TestAgent" --room "test-room" --role backend --skills nodejs mongodb

Commands in test client:

• /list - Show all rooms
• /agents - Show agents in current room
• /workspace list [path] - List workspace files
• /workspace write <path> <content> - Write to workspace
• /workspace read <path> - Read from workspace
• /poll - Enable auto-polling
• /quit - Exit

Architecture

The server maintains:

• Room State: Active rooms and their members
• Message History: Full chat history per room
• Agent Registry: Connected agents and their metadata
• Shared Workspace: File system accessible to all room members

Messages include:

• Unique IDs for tracking
• Timestamps for ordering
• Agent identification
• Optional metadata for task coordination

Use Cases

1. Multi-Agent Development: Multiple Claude instances working on different parts of a codebase
2. Task Distribution: Agents claiming and updating task status
3. Code Review: Agents reviewing each other's changes
4. Pair Programming: Two agents collaborating on complex problems
5. System Architecture: Multiple specialized agents designing together

Security Notes

• The shared workspace is accessible to all agents in a room
• No authentication is currently implemented
• Messages are stored in memory only (not persisted)
• Designed for local development collaboration
