All States Designed

MUST

MUST: Design empty/sparse/dense/error states

Design empty, sparse, dense, and error states

Bad

Good

Why it matters

Every interface has multiple states beyond the ideal happy path. Design and implement empty states (no data yet), sparse states (minimal data), dense states (lots of data), error states (something went wrong), and loading states. Don't leave users facing blank screens.

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.
