Substack Ghostwriting

samber/cc-skills
2k installs178 stars
Summary

This is a production-level ghostwriting skill that treats Substack as what it actually is: a social-media-newsletter hybrid with subscription-driven incentives, not a blog with an email bolt-on. It walks you through voice matching first (sample collection, marker extraction, validation), then forces an intake interview before drafting anything. The workflow splits cleanly between newsletter issues (email-first, subject line optimization) and web posts (SEO-first, evergreen articles), with dedicated formatting guidance for each. What I appreciate is the brutally honest framing on ghostwriting: you're extracting insights from clients who have them but lack time, not generating thought leadership from scratch. If you write for founders or execs on Substack, or run your own technical newsletter, this gives you a repeatable system instead of winging it every week.

blueprint

affaan-m/ecc

Turn a one-line objective into a step-by-step construction plan for multi-session, multi-agent engineering projects. Each step has a self-contained context brief so a fresh agent can execute it cold. Includes adversarial review gate, dependency graph, parallel step detection, anti-pattern catalog, and plan mutation protocol. TRIGGER when: user requests a plan, blueprint, or roadmap for a complex multi-PR task, or describes work that needs multiple sessions. DO NOT TRIGGER when: task is completable in a single PR or fewer than 3 tool calls, or user says "just do it".
