No-Paste Field
A confirm field that refuses paste: an attempt lights up the border and swaps the note below for a couple of seconds, then fades on its own — a silent refusal would read as a broken field.
React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.
What you can change
- the label, placeholder, hint and blockedText copy for your own wording and domain (email, password, code)
- name — drives the field ids and the aria-describedby link
- the accent through the accent prop
A link for your AI agent: preview, code and instructions.

FAQ
- How do I add No-Paste Field with Cursor or Claude Code?
- Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
- What does No-Paste Field depend on?
- No npm packages beyond React and Tailwind CSS.
- What can I change in No-Paste Field?
- Adapt: the label, placeholder, hint and blockedText copy for your own wording and domain (email, password, code); name — drives the field ids and the aria-describedby link; the accent through the accent prop. Keep as installed: the local --vibeui-field-012-* palette — do not swap it for your theme tokens; light-dark() in the palette: the component has to follow the surrounding color-scheme rather than ship a dark theme of its own; preventDefault on onPaste together with a visible reaction — a silent refusal is indistinguishable from a broken field.
- Is No-Paste Field free?
- Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

Technical notes
The component is self-contained: one file, no dependencies, its own palette in local variables --vibeui-field-012-*. A client component: "use client" (the blocked state and its timer). onPaste calls preventDefault and raises data-blocked="1" on the root for 2.4 seconds: the border and the note below change tone, then clear themselves through window.setTimeout with cleanup in useEffect. The hint and the warning share one <p>, linked to the field through aria-describedby and announced with role="status".
