# RAG (Knowledge)

> Native tools to ingest, search, and manage knowledge collections

Toolkit slug: **`flowra_rag`**.

These tools wrap the [Knowledge](/guides/knowledge) API. Collections use **`projectId`** + **`ownerEUID`** — use **`x-username`** per end user ([multi-tenancy](/guides/multi-tenancy)).

| Slug                           | Name                  | What it does                                      |
| ------------------------------ | --------------------- | ------------------------------------------------- |
| `FLOWRA_RAG_LIST_COLLECTIONS`  | RAG list collections  | List knowledge collections for the current owner. |
| `FLOWRA_RAG_ADD_KNOWLEDGE`     | RAG add knowledge     | Add text chunks to a collection.                  |
| `FLOWRA_RAG_ADD_FILE`          | RAG add file          | Ingest a file into a collection.                  |
| `FLOWRA_RAG_ADD_URL`           | RAG add URL           | Ingest content from a URL.                        |
| `FLOWRA_RAG_SEARCH_KNOWLEDGE`  | RAG search knowledge  | Semantic search over a collection.                |

| `FLOWRA_RAG_RENAME_COLLECTION` | RAG rename collection | Rename a collection.                              |
| `FLOWRA_RAG_DELETE_COLLECTION` | RAG delete collection | Delete a collection and all chunks.               |
