skill-no-em-dashes

Enforce em-dash-free writing. Use this skill whenever you write or edit prose for the user, including drafts, emails, essays, reports, documentation, blog and social posts, marketing copy, creative writing, summaries, and rewrites, so the output contains zero em dashes and avoids the grammatical structures that invite them. Replace em-dash constructions with commas, semicolons, colons, periods, or parentheses, and recast sentences when a plain swap would read awkwardly. Trigger this even when the user does not explicitly mention em dashes, dashes, or punctuation, because the point is that every piece of writing comes out clean by default. Also apply it when polishing or proofreading text the user pastes in, and when the user asks for writing that does not look machine-generated.
