## About Shadcn Dialog

### When to use

- Short forms and settings that need an answer before the page continues
- Long text such as terms, read in a scrolling body that can grow to nearly full screen
- Reference overlays and notices, such as a keyboard shortcuts list or a session timeout

### When not to use

- A yes or no confirmation before a destructive action: use [Alert Dialog](https://reui.io/components/alert-dialog.md) (`get_component("alert-dialog")`)
- Long forms or record details that slide in from the screen edge: use [Sheet](https://reui.io/components/sheet.md) (`get_component("sheet")`)
- Mobile panels that open from the bottom and close with a swipe: use [Drawer](https://reui.io/components/drawer.md) (`get_component("drawer")`)

### Agent notes

- Compose the trigger through `render` on the base twin and `asChild` on the radix twin; the other one is silently ignored
- `DialogContent` renders its own close button; pass `showCloseButton` as false to drop it

Every ReUI item has a twin like this one; the index is https://reui.io/llms.txt. Agents with the ReUI MCP (https://reui.io/docs/mcp) get the same guidance from the getters named above.
