# AgentMail Skill AgentMail enables communication between AI agents running in different tmux windows through a simple file-based mail system. ## Overview AgentMail is a CLI tool for inter-agent communication within tmux sessions. Messages are stored in `.agentmail/mailboxes/` as JSONL files, providing persistent, file-locked message queues for each agent. ## Prerequisites - Must be running inside a tmux session - AgentMail CLI must be installed and available in PATH - Messages stored in `.agentmail/` directory ## Core Commands ### Send a Message ```bash agentmail send <recipient> "<message>" ``` Send a message to another agent. The recipient must be a valid tmux window name. **Examples:** ```bash agentmail send agent2 "Can you review the changes in src/api?" agentmail send -r worker -m "Task completed" echo "Build succeeded" | agentmail send agent2 ``` ### Receive Messages ```bash agentmail receive ``` Read the oldest unread message from your mailbox. Messages are delivered in FIFO order and marked as read after display. ### List Recipients ```bash agentmail recipients ``` List all tmux windows that can receive messages. Your current window is marked with `[you]`. ### Set Status `
