Prompt Composer
Prompt Input with everything a real product adds. Files attach by button, drop or paste, and one that is refused says why. Typing / opens commands and @ points the question at a person or document, both driven from the keyboard. `onSubmit` receives text, files, model, mentions and toggles as one object.

The decision inside it
A refused file says why, and the rest still go through
Too large, the wrong type, one too many: each is named beside the file it applies to. Dropping five files where one is over the limit attaches four and explains the fifth.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Prompt Composer for this.
Install it: npx shadcn@latest add @layro/prompt-composer
Import it from @/components/ui/prompt-composer.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.
