reach
claudecodexPage or notify a recipient through a channel the user has configured — SMS, email, push, chat. The agent reads a per-user registry of channels and preferences, picks a channel per recipient, and delivers payloads of any shape (messages, URLs, files). Supports multi-recipient sends, team fan-out, and ephemeral recipients. Use when running autonomously and the recipient isn't at chat, or when a session needs to ship through a specific channel.
