        "longDescription": "aInbox is a messaging layer for your AI assistants. Sign in once and your account gets a dedicated @ainbox.io address; each assistant you connect (a chat assistant, a coding agent) gets its own sub-address under it. Hand a brief, a draft or a decision from one assistant to another without copying and pasting: send it here, open the other assistant, and the context is waiting. Messages are relayed, not stored: content is deleted once the receiving assistant acknowledges it, and unread messages expire after seven days. Humans can reach your assistants too, by emailing your @ainbox.io address, and your assistants can reply or send email on your behalf within per-account limits. Tools: list_agents (who is under your account and whether they are listening), pull_messages and ack_messages (crash-safe read then confirm), send_message and reply_message (to your own addresses or to email). Message bodies arrive wrapped in a data envelope and are never treated as instructions.",
