# Assign Knowledge to Agents

> Connect knowledge bases, folders, or items to an agent from the Knowledge tab

## Overview

In the Agent Editor, open **Knowledge** to connect sources from your knowledge bases.

You can connect at three levels:

* Entire knowledge base
* Folder
* Individual item(s)

Connections use RAG by default." />

## Connect Knowledge

<Steps>
  <Step title="Open an agent">
    Go to **AI Agents**, open an agent, then open the **Knowledge** tab.
  </Step>

  <Step title="Click Connect Knowledge">
    Use **Connect Knowledge** (or **Add Knowledge** from the empty state).
  </Step>

  <Step title="Pick from the knowledge browser">
    In the **Connect Knowledge** panel, use the left tree to select a knowledge base or folder.
  </Step>

  <Step title="Connect at the level you need">
    * Knowledge base level: **Connect Entire KB**
    * Folder level: **Connect Folder**
    * Item level: select items, then use **Connect {count} Items**
  </Step>
</Steps>

***

## What You See After Connecting

The connections table includes:

* **Name**
* **Type** (`Entire KB`, `Folder`, `Item`)
* **Path**
* **Mode** (Expert Mode only)
* **Items**
* Remove action (trash icon)

You can remove a connection at any time.

### Mode Controls

<Badge>Expert Mode</Badge>

<Screenshot lightSrc="/images/agent-editor__knowledge-tab-expert-light.png" darkSrc="/images/agent-editor__knowledge-tab-expert-dark.png" alt="Agent Knowledge tab in Expert mode showing RAG and Context mode controls" caption="Expert mode adds retrieval-mode controls so you can choose RAG or Context per connection." />

You can:

* Choose **RAG** or **Context** when connecting a knowledge base, folder, or selected items
* Change connection mode from the table **Mode** column
* Toggle an existing connection mode from the browser panel

In Simple mode, connections use **RAG** by default.

***

### Context Budget

<Badge>Expert Mode</Badge>

When using Context mode, the UI enforces a **10,000 token** budget across all context connections.

If a source exceeds remaining context budget, the UI blocks the switch and shows a warning.

***

## Connection Behaviors to Know

* If an entire knowledge base is connected, folder/item entries under it are effectively inherited.
* If a folder is connected, items in that folder are inherited.
* The folder browser shows inherited/connected state so you can avoid redundant connections.

***

## Test Your Setup

After connecting knowledge:

1. Open your agent test flow.
2. Ask questions that should be answered from connected sources.
3. Verify answers are grounded in your content.
