In short:
ak-copywritingreads your brief to know what to write, for whom, for what purpose and in which voice, then loads only the template group for that kind of copy. Formulas such as AIDA or PAS are just a frame; the brand voice always wins. Every figure, result and customer quote needs evidence you provided or a citable source.

Summary
Use it when you need headlines, emails, landing pages, CTA buttons or social posts that get readers to act, or want copy that sounds like what you have written before.

E --> BFour concepts to know:
| Concept | Question | Example |
|---|---|---|
| Brief | Which deliverable, for which reader, for what purpose, in which voice? | The hero section of a landing page for a budgeting app, readers are students, the goal is trial sign-up, the voice is friendly |
| Voice before formula | The formula suggests urgency but the brand is calm; which wins? | A premium furniture brand does not say "only 3 left"; the skill writes calm, specific lines instead of fake scarcity |
| Evidence for claims | Where does this figure, result or praise come from? | With a test results file, it writes "cuts data entry time by 30%"; without one, it drops the line or marks it as a proposed claim |
| Your own writing style | Want the copy to sound like your past posts? | Put a few old blog posts in assets/writing-styles/, and the skill extracts the voice and writes in it |
Type it as /ak-copywriting <copy type> <context>. The bundled formulas include AIDA, PAS, BAB, 4Ps, FAB, 4Us; the skill picks by situation and does not force any of them.
Sample prompt for a landing page hero:
/ak-copywriting landing page Write the hero section for <product name>, a budgeting app for students.
Readers: first-year students who know they overspend but have not used any app.
Goal: click "Try for free".
Voice: friendly, concise.
Evidence: only use the figures in <figures file path>.
Save to <output file path>.This skill has no flags.
