You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: multimail-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Use multimail-pp-cli when you need to manage an agent email fleet — process oversight queues, monitor trust ladder progression, search across mailboxes, and track inbox health. It turns MultiMail's graduated autonomy model into a daily operator workflow. Anti-triggers Do not use this CLI for: Sending bulk marketing email — MultiMail is for agent-to-human communication, not mass email Managing non-MultiMail email accounts (Gmail, Outlook) — use better-email-mcp or native MCP tools Real-time email streaming — use MultiMail webhooks directly for sub-second event delivery Account billing changes — use the MultiMail dashboard for payment and plan management Unique Capabilities These capabilities aren't available in any other tool for this API. …
