copywriting-engine skillA

copywriting-engine is agent-read markdown (skill) from quionie/claude-content-engine: Write persuasive copy for any medium: headlines, taglines, landing pages, ads, product descriptions, CTAs, or email copy. Use this skill when the user needs copywriting, wants to write marketing copy, asks for headlines, taglines, ad copy, landing page text, product descriptions, value propositions, calls to action, or says things like "write copy for", "help me sell", "make this more compelling", "punch up this text", or "write a headline"..

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.
