You have a pile of notes or a messy draft and you want it shaped into an actual article. This skill runs a conversational editing session that starts by drafting 2–3 candidate openings, forces you to pick one, then builds the piece paragraph by paragraph. It argues with you about format at each step: should this be prose or a list, does this deserve a callout, is this transition earning its place. The raw material file stays untouched. Everything gets written to a separate article document as you go, so you can edit between turns and watch the piece take shape. It's opinionated about structure and will push back if something doesn't land.
