# Knowledge base

> Give agents retrievable context from URL, text, and file documents organized into folders.

The Agents Platform knowledge base stores URL, text, and file documents that an agent can retrieve during a conversation.

## Content operations

* Add URL, text, and file documents.
* Organize documents into folders.
* Search by text and filter by document type.
* Read metadata, content, source files, and chunks.
* Refresh URL documents or replace file sources.
* Move or delete one or more items.

## Retrieval

RAG index operations expose index status and document chunks. The agent query operation runs the agent's current retrieval configuration without creating a conversation.

## Dependencies

Dependency operations identify agents that use one or more knowledge base documents. Check those dependencies before deleting or replacing published content.
