Write or rewrite any text a user reads (interface strings, errors, empty states, landing and pricing pages, posts, changelogs, store listings, ads, email): apply when asked to write copy, rewrite a headline or CTA, fix microcopy, or when a draft reads machine-made.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# copywriting — write it in the product's own voice

`brand-voice` decides how the product speaks. This is the pass that writes
in it. The two are not interchangeable: defining a voice mid-sentence to
finish a button is how a product ends up with six voices.

## First action, every time

Read the pack: `docs/brand/voice.md`, `terminology.md`, and the
`channels.md` record for the surface being written. **No pack? Stop and run
`/brand-init`.** Guessing the voice and being wrong costs more than the
pause.

**Never write to `docs/brand/`.** A term missing from the dictionary, or a
number with no row in `facts.md`, is **reported** — never invented to finish
the sentence. Adding it is `brand-voice`'s decision, not this pass's.

## Rules that hold in every voice

- **Every figure comes from `facts.md`.** No sourced fact, no number. Never
  fabricate a statistic, a quote, or an expert.
- **One action keeps one name** across button, confirmation, toast, history,
  notification and accessible name. Search `strings.md` before naming one.
- **No humor, exclamation marks or emoji** on error, destructive confirm,
  billing or paywall surfaces — including in a playful voice.

How to install

The exact contents, by fingerprint

mdr add ssheleg/super-ux/.cursor/rules/copywriting.mdc@sha256:ce426497d0bc3a30

The line at the top of this page pins the label git:20260909.1c2e4ab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
