AgentMail, Printing Press CLI

Prerequisites: Install the CLI

This skill drives the agentmail-pp-cli binary. 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:

   npx -y @mvanhorn/printing-press-library install agentmail --cli-only
   

2. Verify: agentmail-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). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/social-and-messaging/agentmail/cmd/agentmail-pp-cli@latest

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.

The CLI covers AgentMail's inbox, message, thread, draft, webhook, domain, list, metric, key, pod, and organization surfaces. It adds local triage queues, pre-send risk checks, conversation rollups, schedule audits, delivery reconciliation, and fleet health so agents can reason across time and resources instead of replaying isolated API calls.
