Creates or changes something that can be changed back. Claude Code: ask.

### `create_branded_link`

- The name "create_branded_link" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Creates a permanent public page (screenparty…/r/<slug>) with a name, an optional one-line description, colour and video; everyone who opens it lands in that page's room. For teachers, classes and communities. Returns the public link and a private edit link (where a logo, background and a QR-code poster can be added). The edit link must be kept private.
```

### `create_watch_room`

- The name "create_watch_room" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Creates a private ScreenParty room that friends join from a link, now or at a scheduled time, optionally with a video already loaded. Returns the room link to share. The first person to open the room becomes its host (controls playback), so the user should open it before sharing.
```
