Generate Substack post
generate_substack_postRead-only
Draft one Substack post and save it to the user's files, ready to paste into their Substack editor. Nothing is published and nothing is sent. Drafts are limited to 20 per day. Templates: 'post' takes signoff; 'digest' takes intro, signoff. Write the body as markdown (paragraphs, lists, links) or as blocks, never both. The title and subtitle are the post's own headline and standfirst. audience is everyone, paid or founding. It costs 1 credit, or nothing on a Solo or Pro plan. Do not call this again to retry. When Substack is connected, call get_my_substack_voice first and write the post in that voice.
