Command

Syntax Hints

A palette with prefix syntax where an empty result answers with a legend of the symbols instead of a bare "nothing found" line.

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 entries array and the set of prefixes
  • the field hint through the placeholder prop
  • the wording of the syntax legend through the hints prop

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Syntax Hints 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 Syntax Hints depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Syntax Hints?
Adapt: the entries array and the set of prefixes; the field hint through the placeholder prop; the wording of the syntax legend through the hints prop. Keep as installed: the local --vibeui-command-007-* palette — do not swap it for your theme tokens; the legend instead of a "nothing found" line: an empty list is where the user got stuck; the mode chip at the field: without it the list swap looks random.
Is Syntax Hints free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

This command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options

Technical notes

The component is self-contained: one file, no dependencies, its own palette in the local --vibeui-command-007-* variables. Client-side: "use client" for the sake of parsing the query. The first character of the query determines the mode: > for commands, @ for symbols, # for lines; the same character is shown as a chip to the left of the field, so the link «typed a prefix — the list changed» is obvious. An empty result is replaced by a legend of the prefixes: a list with no rows is where the user got stuck, and a hint is more useful there than a no-matches message. The combobox, listbox and option roles are declared explicitly.
