What it does

This skill teaches an AI agent to review and improve copy you already have, such as landing pages, emails, or blog posts. Instead of rewriting everything at once, the agent checks the text in a fixed series of focused passes (clarity, voice, benefits, proof, specificity, emotion and more), explaining each change. It also removes common signs of AI-generated writing, and makes only minimal edits when you ask about a single line.

Great for

  • Marketers polishing landing pages, emails, or ads they already wrote
  • Founders who want a clear, evidence-backed version of their website copy
  • Anyone whose draft reads awkwardly or sounds like generic AI text
  • Teams refreshing outdated pages or running a content audit

Skip it if

  • Writing brand-new copy from scratch, since the skill is for improving existing text (a separate copywriting skill is referenced for that)
  • Legal, medical, or regulated claims that need expert review, because the skill checks style and proof gaps but cannot verify facts

Try asking

  • “Review my copy and tell me what to tighten on this landing page.”
  • “This paragraph reads awkwardly, can you clean it up without changing my message?”
  • “Refresh this outdated product page and flag claims that need proof.”
  • “Make this email sound less like AI and more human, but keep my wording where it works.”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Say whether you want a full edit or a single-line fix, since a point edit changes only what you asked for.
  • Add your product marketing context file if you have one, so edits match your brand voice and customer language.
  • Provide the goal of the copy (audience, offer, call to action) so the agent can judge what counts as persuasive.
