copywriting
Writes or rewrites persuasive marketing copy for any page — homepage, landing, pricing, feature — built around clarity, specificity, and customer language over company language.
What it actually does
- Gathers page purpose, audience, product/offer, and traffic context before writing, then applies a fixed set of principles: clarity over cleverness, benefits over features, specificity over vagueness, customer language over company language, one idea per section.
- Applies concrete style rules (simple over complex, active over passive, no exclamation points, no unearned adverbs) and explicitly flags fabricated statistics or testimonials as a trust and legal problem, not just a style issue.
- Outputs organized page copy (headline, subheadline, CTA, section-by-section body), annotations explaining the reasoning behind key choices, and 2-3 alternative options for headlines and CTAs.
When to use it — and when not to
Use it when
- You need copy written or rewritten for a page meant to persuade — homepage, landing page, pricing, feature, or about page.
- Existing copy reads unnatural, vague, or unconvincing and you want it rebuilt around a stated set of principles rather than a generic rewrite.
Not for
- You're polishing a draft line-by-line rather than writing new copy — that's `copy-editing`, meant to run after this skill's draft.
- The page's structure or conversion strategy is the actual problem, not the words on it — see `cro`.
- You need email, popup, or SMS copy specifically — those have their own skills (`emails`, `popups`, `sms`) tuned to those formats.
The caveat that matters
It draws a hard line on fabricated proof: "Fabricated statistics or testimonials erode trust and create legal liability" is stated as a principle, not a suggestion — worth knowing if you're hoping it will invent social proof for you.
Agent compatibility
- Claude Code
marketingskills' README states the collection "works with Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent that supports the Agent Skills spec" as a collection-wide claim.
- Codex
Same collection-wide compatibility statement.
- Cursor
Same collection-wide compatibility statement.
Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.
Requirements and operational surface
What it actually does at runtime
- Reads `.agents/product-marketing.md` (or the legacy `.claude/` path) if present, for shared product context — no writes or network access of its own
Workflow fit
product-marketing context → copywriting draft → copy-editing polish → ab-testing to validate.
