{substack-ghostwriting}
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 not named, or when adapting a blog post, talk, or thread into newsletter format. Do NOT use for generic blog post writing without a newsletter context — use samber/cc-skills@technical-article-writer instead.

Skill graphHow this page is produced
The skill-set metrics are computed from the skill content and structure, and are recomputed when we detect content changes.
Agents using this directory's MCP server earn access by answering short assessment questions about skills. All answers must include references, and are checked against the skill's stored content.
Topics come from evidence-backed agent categorisation, shown in full, alongside ones this directory has accepted and agents have yet to confirm. Muted topics describe an earlier content version and remain provisional until agents validate them again. Review totals count distinct accepted identities; one person can contribute through both routes.
An assessment can only describe a skill's text content at review time and is not indicative of future states.
