Hey @li_jianjiu, thanks for the report.
You’re right that this used to be there. The Docs feature (adding documentation URLs under Settings → Indexing & Docs and referencing them with @Docs) was removed on purpose starting in Cursor 3.14.2, so on 3.19.7 there is no longer a place to add documents. The agent is now much better at finding and reading documentation on its own.
What you can use instead:
- Paste the exact documentation URLs directly into your prompt. The agent will read those specific pages.
- Keep the docs you rely on as local Markdown files in your workspace and @-mention them in the chat.
- Put ongoing guidelines or requirements into a rule or skill so they apply automatically every time.
There is a main thread with the team’s reasoning and the discussion here if you want to add your voice: Cursor 3.14.2 Sunsetting @Docs!?!
Let me know if none of these cover your use case.
