The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill installs the multimail-pp-cli tool using npx from the vendor's official @mvanhorn/printing-press npm package and go install from the vendor's repository at github.com/mvanhorn/printing-press-library. These resources are hosted on well-known, trusted registries.
[COMMAND_EXECUTION]: The skill executes the multimail-pp-cli binary to perform various email-related tasks, including account management, API key rotation, and audit log retrieval. It also invokes npx, go, and claude commands during the initial setup and configuration phases.
[DATA_EXFILTRATION]: The CLI includes a documented --deliver webhook:<url> feature. This capability allows the agent to route the JSON output of any command to an external HTTP endpoint, providing a functional mechanism for data delivery to third-party services.
