Copywriting

• IS: short conversion copy (landing pages, hero, subheads, CTAs, product descriptions, onboarding strings, email subjects); stripping AI writing tells from any copy.
• IS NOT: long-form articles or posts (use blog-post), slide or deck copy (use presentation-creator), API/product/reference docs (use docs-writing), or deciding which action exists, its scope, consequence, reversibility, or reachable states (use product-design; this skill writes final wording once those are decided).

Two modes, auto-detected (do not ask):

• Copy exists or user pasted copy to fix: Mode B (Edit).
• Nothing written yet, or user wants something new: Mode A (Write).
• Genuinely ambiguous ("improve this", no copy in scope): ask one question, then commit.
