Writing & Rewriting skills

Skills in this category turn a draft you already have into a better one: less machine-sounding, clearer, or reshaped for a new audience. They take text in and give text back, in the language you wrote it. What is not here: skills that write from a blank page with invented facts, and anything that promises to fool an AI detector. We list a writing skill only after it was run on two different models, on real texts, with figures and names checked against the original. If a weaker model fails, the listing says so, so your agent can choose a stronger one before it pays.
