CCCC
CCCC coordinates several coding agents, such as Claude Code, Codex and ChatGPT Web, as one persistent team by recording every message in an append-only ledger, tracking delivery and read status, and exposing that state to a web UI, CLI and MCP tools.
CCCC coordinates multiple coding agents as one durable, persistent group instead of a set of disconnected terminal sessions. Message history is kept in an append-only ledger, and tasks and shared context have their own persistent stores, so state survives a restart.
Delivery, read and reply status are tracked as separate, visible facts rather than assumed from a prompt, and a Web UI, CLI, MCP tools and instant-messaging bridges all operate on the same daemon-owned state. Supported runtimes include Claude Code, Codex CLI, ChatGPT Web and Grok Build, and instances can connect to each other through same-account discovery or approved cross-member connections. It installs with a single command and needs no separately operated database or message broker.
