plain-sales-copy skillA

plain-sales-copy is agent-read markdown (skill) from labs21-dev/agents-stack: Write or rewrite any sales or business content so a stranger gets it in 3-5 sentences, needs no glossary, and meets zero puff adjectives. Use when the user asks for a sales pitch, elevator pitch, cold email, landing-page hero, homepage copy, one-pager, pitch-deck opener, investor blurb, about-us, pricing intro, LinkedIn outreach, value proposition, ICP messaging, or says "make this less salesy", "too much jargon", "rewrite this pitch", or "what do we actually say". Also use when existing copy is.

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

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.
