Rewrites marketing and product claims into the premium register - every quantified claim carries a number, a baseline, and a footnote, headlines run 7 words or fewer in sentence case with a concrete noun, an intensifier lint bans hype words without adjacent numerals, and voice is defined as X-not-Y spectra. Use when someone asks "make this headline sound premium", "remove the hype from this copy", "does this claim need a number", "our copy sounds like every other startup", "rewrite this without buzzwords", or copy leans on intensifiers instead of evidence. Do NOT use to write a full landing page section by section - use landing-page-copy instead; for auditing an in-product copy corpus, use ux-writing-audit; for the brand voice document itself, use brand-guidelines.

# premium-copy-register
Readers process specifics as evidence and vague intensifiers as advertising - the strongest single convergence across premium craft practice. Design-literate audiences pattern-match hype copy faster than any visual tell, and display type magnifies weak words: a padded verb that hides at 17px is an embarrassment at 64px. The costly failure this skill prevents is the beautifully designed page whose headline reads "Supercharge your workflow" - the copy alone outs the whole page as generated.
## Operating procedure
Run the steps in order: lint before rewrite, rewrite before receipts. You cannot attach evidence until the hype is stripped and the real claim is visible underneath it, and you cannot set voice spectra until you have seen what the claims actually are.
### Step 1: Gather the corpus, the proof, and the charter
Ask for five inputs before touching a word:
1. The **corpus** in scope: headlines, subheads, CTAs, and quantified claims, each tagged with its role.
2. The **proof** actually available: metrics, baselines, sources, customer counts. Never invent these. A receipt with an invented number is worse than no receipt, because one fabricated figure poisons every true claim beside it.
3. The client **charter** voice character. Paste the charter block if one exists. If the client has a charter but the foundations pack is not installed, elicit the needed values directly and label them provisional. If no charter exists at all, halt and route to premium-design-foundations - never substitute worked-example values. The charter is this skill's pass/fail baseline; rewriting without it enforces house taste instead of the brand's recorded decisions.
4. The **surface** the copy ships on (hero, store listing, deck slide) - register tightens as type gets bigger.
5. Three **voice adjectives** and three forbidden registers, if a voice spec exists. If any input is a guess, label it a guess and move on.
