newsletter skillA

newsletter is agent-read markdown (skill) from openclaudia/openclaudia-skills: Plan and grow an email newsletter. Use when the user says "newsletter strategy", "grow my newsletter", "newsletter content", "email newsletter", "subscriber growth", "newsletter monetization", "Substack strategy", "Beehiiv", or asks about building, growing, or monetizing a newsletter..

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 openclaudia/openclaudia-skills/newsletter@git:20260212.78e31a7
Exact content
mdr add openclaudia/openclaudia-skills/newsletter@sha256:ea1925e454172367

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.
