# Missing Knowledge

If your AI agent responds with:

> “I don’t have information about that.”

It means the system couldn’t find a confident match in your knowledge collection.    
This guide shows you how to identify, verify, and correct missing or mismatched knowledge so your agent always delivers accurate, complete answers.

## **Step 1: Review a Conversation Session**

Go to the **Sessions** tab in your MagicBlocks dashboard.![1](https://export.supademo.com/renders/6wzm8opvgm/out.png)

Open a conversation where your agent gave an incorrect or incomplete response.

Click the **Robot Head** icon in the top-right corner of the chat view.

This opens the **AI Debug Panel**, which shows how the AI built its response, including what knowledge it retrieved and how it used it.

## **Step 2: Check What Knowledge Was Used**

Scroll through the debug details until you see a section labeled **Knowledge Used**.

Expand this section to see:

-   Which knowledge document or webpage was referenced
-   The specific text retrieved from your collection
-   Compare this content with the answer you expected.

If the correct answer exists but wasn’t matched:

-   Try rephrasing the question or related keywords inside your knowledge article.
-   Add more context to help the AI make stronger matches in future.

## **Step 3: Verify Knowledge Linkage in the Agent**

Go to the **Agents** tab and open the relevant agent.![15](https://export.supademo.com/renders/ovytal9dwk/out.png)

Click into the specific **Journey Block** where the issue occurred (for example, “Confirm Details” or “Pricing”).![17](https://export.supademo.com/renders/uf8lrlq50u/out.png)

Under the **Advanced** tab, review the **Knowledge Source** field.![36](https://export.supademo.com/renders/1psbexut9x/out.png)

Make sure it’s linked to the correct knowledge collection.![39](https://export.supademo.com/renders/rdusavsxmp/out.png)

If you’ve recently created a new collection, double-check that the block isn’t still pointing to the old one.

You can select multiple knowledge collections if needed. If this field hasn’t been edited, it typically inherits the agent-level knowledge automatically—but it’s worth confirming nothing has been overridden or locked.

## **Step 4: Search Inside the Knowledge Collection**

Open the **Knowledge** section in your sidebar.![45](https://export.supademo.com/renders/qbvy3voeoh/out.png)

Choose the collection that should contain the relevant content.

Use the search bar to locate the information:![61](https://export.supademo.com/renders/vkyae0r30v/out.png)![62](https://export.supademo.com/renders/93ikgjx53f/out.png)![69](https://export.supademo.com/renders/v5ykvrhfxf/out.png)

-   Search by **keyword** for quick matches (e.g., “pricing”)
-   Or enter the **full user question** (e.g., “How can I move into a new plan?”)
-   The second method simulates how the AI searches by meaning, not just by keyword.

If nothing is found:

-   Add a new entry that directly answers that question.
-   Save and rebuild your knowledge base.

## **Step 5: Test the Updated Response**

After making adjustments:

1.  Return to your agent’s **Test Mode**.
2.  Ask the same question again.
3.  Confirm the new response is accurate, clear, and uses the intended knowledge source.

## **Quick Checklist**

-   Open and review the session using the Robot Head panel
-   Verify the correct knowledge source is linked
-   Add or refine missing content in the right collection
-   Re-test until the agent responds accurately
-   Each time you refine your knowledge, your AI becomes more confident and capable in real conversations.

## **Pro Tip**

If you notice repeated “no information found” messages, review the **Missing Knowledge Report** in your Agent Dashboard. It compiles all weak or incomplete knowledge responses, allowing you to resolve them in one place.![68](https://export.supademo.com/renders/rtxq8hy9cn/out.png)
