It's a Substack-specific growth/ghostwriting workflow (algorithm mechanics, Notes strategy, monetization math), not a generic newsletter tool — and Phase 1 is a hard stop: it produced five subject-line variants and three distinct hooks for review before writing a single word of body copy, versus a baseline that just wrote one draft outright. (Listed here under our older name; the skill's own name is "Substack Ghostwriting & Content Optimization".)
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5

- Output vs. baseline 9/10
- Docs & honesty 5/5
What Substack Ghostwriting & Content Optimization does
Writes and optimizes Substack newsletter issues and web posts, covering voice matching (own-voice or ghostwriting), Substack's algorithm mechanics, Notes strategy, email vs. web formatting constraints, SEO, and paid-tier strategy. Phase 1 is a hard stop: it interviews the user on topic, format, audience, objective, and length before drafting anything, and offers (never auto-generates) social distribution posts. Built specifically for Substack, not generic newsletter or blog writing.
