AssistantComplete

Two decisions need an owner.

This local example uses recorded response alternatives.

When to use

Use it for

Edit a supplied message with an application-owned async save. Failed saves preserve the draft.
Compose this editor with ResponseBranch when editing produces another response version. The application owns regenerate requests and history.
Escape or Cancel invalidates local pending feedback and calls onCancel.

Avoid

Treating local cancellation as cancellation of a backend operation; pass and manage that signal in the application.

Props

ResponseEditor

Multiline message editing with async save, cancellation, and failed-draft retention.

Prop	Type	Default

`onSave`required	`(text: string) => void \| Promise<void>`
`onCancel`required	`() => void`
`label`	`string`	`"Edit message"`
`saveLabel`	`string`	`"Save message"`
`disabled`	`boolean`
`onError`	`(error: unknown) => void`

Also accepts Omit<FormHTMLAttributes<HTMLFormElement>, "onSubmit" | "onError">.

The ref reaches HTMLFormElement.

Keyboard

Keys	Does
`Tab`	Moves through the supplied native controls in reading order
`Enter, Space`	Activates focused buttons and disclosure summaries
`Escape`	Cancels the editor and invalidates pending feedback

Accessibility

Native attributes, className, style, and the forwarded ref reach the outer element.
Interactive content requires accessible names; progress text is not announced for every streamed token.

Markup

The same styles are available as CSS. Native HTML provides the static presentation; React or application code supplies state updates and actions.

npm install @noorddev/vlak

import "@noorddev/vlak/css";

<form class="rs-response-editor" aria-label="Edit message"><label>Message<textarea>Review the brief</textarea></label><div class="rs-response-editor-actions"><button class="rs-btn-subtle" type="submit">Save message</button></div></form>
