Introduction

CCCC (Collaborative Code Coordination Center) is a local-first multi-agent collaboration kernel that helps you coordinate multiple AI agents to work together on software projects.

What is CCCC?

Think of CCCC as a "group chat for AI agents" with execution capabilities:

• Working Groups: Like IM group chats, but with durable history and automation
• Multiple Agents: Coordinate Claude Code, Codex, Droid, OpenCode, Copilot, and more
• Web Control Plane: Mobile-first responsive UI for remote access
• IM-Grade Messaging: @mentions, reply/quote, read receipts, and consistent behavior

Key Concepts

Working Group

A working group is the collaboration unit in CCCC. Each group has:

• An append-only ledger as the single source of truth
• One or more actors (agent sessions)
• Optional scopes (project directories)
• Automation rules for nudges, timeouts, etc.

Actor

An actor is an agent session within a working group:

• Foreman: The first enabled actor becomes the coordinator + executor
• Peer: Additional actors serve as independent experts

Actors can run in two modes:

• PTY (Terminal): Interactive terminal session with embedded xterm.js
• Headless: MCP-only mode for autonomous operation

Ledger

The ledger is an append-only event stream that stores:

• All messages (user → agent, agent → agent)
• State changes (actor status, context updates)
• Decisions and outcomes

The daemon is the single writer to ensure consistency.

Who Should Use CCCC?

CCCC is designed for:

• Developers who want to leverage multiple AI agents on a single project
• Teams who need to coordinate AI-assisted development
• Power users who want remote access to their AI agents from mobile devices
