Numerals for Counts

MUST

MUST: Write counts and quantities as numerals — "8 deployments", not "eight deployments" — so they can be scanned, compared, and aligned.

Write counts and quantities as digits so they can be scanned instead of read

Bad

Good

Why it matters

Digits have a different visual shape than surrounding words, so the eye locks onto them without parsing the sentence. Spelled-out numbers force serial reading and make values impossible to compare, sort, or align in a stat row or table.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
