Never Block Paste

NEVER

NEVER: Block paste in input or textarea elements. Users paste from password managers, notes, and other sources. Blocking paste creates friction and security issues.

Never prevent users from pasting into form fields - it breaks password managers and accessibility

Bad

Good

Why it matters

From the Interaction constraints in ibelick's baseline-ui skill. Blocking paste breaks password managers (which is how strong, unique passwords get used at all), blocks users with motor disabilities who rely on assistive input, and forces people to retype sensitive data by hand — where they make errors and pick weaker values.

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.
