Newsletter Voice
/newsletter-voice
Build newsletter writing instructions inside a Codex or Claude project. Runs after voice-builder. Produces newsletter-voice.md, a single file the assistant references when drafting newsletters in your voice. Works with or without existing newsletter samples: if you have past issues, the skill analyses them, if not, the skill offers 6 archetypes tuned to your voice.
Free. Built and used by me, Charlie Hills.
