What does copywriting do?
copywriting is a Claude skill that writes or rewrites marketing copy for homepages, landing pages, pricing, feature and about pages. It first reads a product-marketing.md context file if one exists, then asks about the page goal, audience, offer and traffic source. Next it sorts the job into one of three cases: a blank brief, a draft with a real voice to restore, or a point edit that changes only what you asked. It drafts each unit several ways, tests every line for a concrete image and proof, and bans common AI tells. Output is page copy by section, with annotations and two or three headline and CTA options.
When should you use copywriting?
Use it when
- Your homepage headline says nothing specific
- A draft reads like generic AI text
- You need two or three CTA options to test
Skip it when
- You need email sequences or popup copy
- You want light line edits on finished copy
What it needs and what it can touch
