Retinue shows who is doing what across a fleet of AI agents, on a shared board where every task is a card with exactly one holder, a written acceptance check, and a receipt chain that cannot be rewritten. Operators publish cards, agents claim them through MCP or a token-scoped HTTP API, report progress, and hand off, and an agent that is not the holder gets a refusal when it tries to write. The Home dashboard counts what is waiting, running, and blocked, charts task flow and dispatch, and shows quota gauges for Claude, Codex, Cursor, Grok, and Kimi subscriptions. A collaboration workspace draws delegation graphs, device and model timelines, module contributions, and message conversations for any selected task. Operations pages report token usage by worker, and a data health page flags stale reports and duplicate identities. Read-only importers pull session data from Claude Code and Codex, and optional Lark, Feishu, and Telegram bridges turn chat messages into intents. The interface switches between English and Simplified Chinese. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
