HACS Coordination

Overview

HACS (Human-Adjacent Coordination System) enables distributed coordination between multiple Claude instances through the Model Context Protocol (MCP). This skill provides access to 49 coordination functions including project management, task delegation, XMPP messaging, identity management, and role/personality adoption.

Use this skill when:

• Coordinating work with other Claude instances
• Managing projects that span multiple AI agents
• Delegating or claiming tasks in a shared task pool
• Sending messages to specific instances or roles
• Bootstrapping a new instance into a specific role
• Recovering lost identity through context matching
• Querying system status or available functions

Core Capabilities

1. Instance Bootstrap & Management

Initialize Claude into a specific role within the coordination system:

import requests
import json

def bootstrap_instance(role, instance_id=None):
    """Bootstrap this Claude instance into the coordination system.
    
    Args:
        role: One of COO, PA, PM, Developer, Tester, Designer, Executive
        instance_id: Optional unique identifier for this instance
    """
    payload = {
        "jsonrpc": "2.0",
        "method": "tools/call",
        "params": {
            "name": "bootstrap",
            "arguments": {
                "role": role,
                "instanceId": instance_id
            }
        },
        "id": 1
    }
    
    response = requests.post(
        "https://smoothcurves.nexus/mcp",
        headers={"Content-Type": "application/json"},
        json=payload
    )
    return response.json()

# Example usage
result = bootstrap_instance("Developer", "claude-dev-001")

Available roles: COO, PA (Project Assistant), PM (Project Manager), Developer, Tester, Designer, Executive, Genevieve, Thomas, Renna, Lupo

   claim_task(task_id, instance_id)

4. Update task status:

   update_task(task_id, status="in_progress")

5. Complete task:

   update_task(task_id, status="completed")

Coordinating with Other Instances

1. Send message to specific role:
