Brand voice and copy — docs/brand/ is the source of truth for how the product speaks; any public-facing text change updates it in the same change and passes docs/brand/lint.py.
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
# Brand voice (super-ux)
`docs/ux/` decides what the product does. `docs/brand/` decides how it
speaks, under `brand-contract v1`.
## Before writing any user-visible text
Read `docs/brand/voice.md`, `terminology.md`, and the `channels.md` record
for the surface. No pack yet → run `/brand-init` rather than improvising a
voice; a product whose copy was invented surface by surface is the drift
this layer removes.
## Rules
- Any change to public text updates `docs/brand/` in the same change.
- Never quote a figure with no row in `facts.md`. Never invent a fact,
statistic, quote or expert — report the gap.
- One action, one name, everywhere it appears. Check `strings.md` first.
- A register moves the voice axes; it never crosses the invariants listed in
`voice.md`.
- No humor, exclamation marks or emoji on error, destructive confirm,
billing or paywall surfaces, in any voice.
- New interface strings get a `strings.md` row: key, `file:line`, scenario.
## Check
```bash
python3 docs/brand/lint.py
```

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.
A 14 of 14 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
