## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/notion.com/switch_language`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/notion.com/switch_language
```

## Input

- `language` (string, required): Target display language.

## Output

- `language` (string, required)
- `alreadySet` (boolean, required)
- `docLang` (string, optional): document.documentElement.lang after the switch, waited for until it agrees with the requested language. On the already-set path the tab may have booted from Notion's cached shell still rendering the previous locale, so it is reloaded once before the guard gives up.
