Allow or block DuckAssistBot in robots.txt
Add either rule to the robots.txt at your site root. robots.txt is a request, not a lock: this operator documents honouring it, so the rule is normally enough.

Worth knowing before you block: this is a retrieval crawler. Blocking it removes your pages from what the AI models can read and cite live, which usually costs visibility rather than protecting anything.
