RAG Collections are workspace knowledge sources that agent nodes retrieve from at runtime. You manage collections under BUILD → RAG Collections, then attach them on each agent node’s RAG tab in Graph Studio.

Connectors

Files, URLs, Notion, Confluence, Drive, and SharePoint.

Attach to nodes

Attach collections (not individual files); set threshold and top k.

Graph Studio

Design Agent Graphs that ground answers in collections.

Collections vs node attach

Attached collections appear on the node card (folder badge) and in the drawer under Knowledge.

​
Create a collection

  1. Open BUILD → RAG Collections.
  2. Click + New Collection (Create Collection).
  3. Set name, optional color, chunk size, and chunk overlap, then confirm.
  4. Open the collection to add sources.

​
Chunk size and overlap

Set chunk size and chunk overlap when you create the collection (also visible under Collection configuration). Overlap must be less than chunk size. Larger chunks preserve context; smaller chunks improve precision for narrow questions. Re-index after changing chunk settings when the UI prompts you.

​
Next steps

  1. Add connectors (files, websites, wikis, synced folders).
  2. Attach collections on Master or Child Agent nodes.
  3. Save the Agent Graph, then Build — builds pin the RAG collection snapshot used at runtime.
