substack-ghostwriting skillA
substack-ghostwriting is agent-read markdown (skill) from samber/cc-skills: Write, optimize, and grow Substack content — newsletter issues (email-first) and web posts (web-first essays). Covers voice matching, Substack algorithm and Notes strategy, email formatting, SEO, growth tactics, and paid-subscriber monetization. Use when the user mentions Substack, a newsletter issue, a Substack post or article, evergreen content, newsletter growth, Notes, paid subscribers, 'ghostwrite for', or 'write in the style of' — and for newsletter or essay writing even when Substack is n.
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.
