What's inside
- Skill name
sendmux-cli- Description
- Use when a user wants to run the Sendmux **CLI** (the `sendmux` terminal binary) — installing it, OAuth login/logout, connection checks, agent inbox registration and owner invites, managing API-key or OAuth profiles, key-scope preflight errors (e.g. root vs mailbox vs agent key), `--json` output, or invoking Management, Mailbox, and Sending operation commands (domains, mailboxes, webhooks, messages, search, sending email, attachments, delivery logs) via `sendmux COMMAND --flag` syntax. Trigger for "what sendmux command", "how do I run/install sendmux", CLI flag or error questions, and profile/credential setup in the terminal. Do NOT trigger for using Sendmux through MCP tools, the REST API directly from code, or general email-sending strategy questions unrelated to the CLI.
