mailgun-setup skillA

mailgun-setup is agent-read markdown (skill) from vellum-ai/vellum-assistant: Set up and send emails via a user-provided Mailgun account (BYO email provider).

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add vellum-ai/vellum-assistant/mailgun-setup@git:20260702.6c6fc7d
Exact content
mdr add vellum-ai/vellum-assistant/mailgun-setup@sha256:043d6fc064d4e273

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
