About this task

A Knowledge Graph is a semantic layer that connects data, relationships, and context across your enterprise. It structures information as a graph of entities and their connections. This lets AI agents understand how real-world entities relate to each other and retrieve the facts they need to take action accurately. When adding a Knowledge Graph tool, you can configure its query instruction, conversation history, execution mode, output display, and processing messages to ensure the tool works effectively within your AI agent's workflow.

Procedure

  1. In the Tools section, select Add tools, then Create new tool, then select Knowledge graph.

  2. Select a Knowledge Graph from the Select knowledge graph dropdown.

  3. Enter a name for the tool in the Name field.

  4. Enter a detailed description of the tool in the Description for this AI agent field.

    A thorough description helps the AI agent understand what the tool does and when to use it.

  5. Enter a query instruction in the Query instruction field.

    The query instruction should be a direct translation of the request into a search query without any added interpretations.

  6. Toggle Conversation history to control whether the tool uses conversation history.

  7. Select an execution mode under Execution mode.

    Choose Supervised to require human oversight when the tool executes, or Autonomous to allow the tool to run without human intervention.

  8. Toggle Display output to users to control whether the tool's output is shown to users.

  9. If display output is enabled, select an output widget from the Widget dropdown.

    Widgets can only be used by assistants built in Premium Chat experiences. Select the widget type that best formats the tool's output for users.

  10. Choose whether to display a refined widget message under Display refined widget message.

  11. Expand the Advanced settings section to configure output transformation and processing messages.

    1. Select an output transformation format from the Output transformation format dropdown.

      Raw output data usually needs to be transformed into a format that is user-friendly and readable. You can also transform data into smaller formats to reduce the amount of data the AI agent needs to analyze. Transforming data involves tradeoffs between data completeness and latency.

      The available output transformation formats are:

      • None: Output data isn't changed into a different format and users will see raw data.
      • Concise: Output data is changed into the most minimal format for users, with less data for the AI agent to analyze.
      • Verbose: Output data is changed into a summary-like format for users, with slightly less data for the AI agent to analyze.
      • Paraphrase: Output data is changed into a format featuring direct statements for users, with no reduction in data.
      • Custom: Output data is changed into a format you specify (consider data loss and performance issues).
    2. Write processing messages for users under Write processing messages for users.

      Describe the action that happens while the tool is running in the In-progress message field and the final action when the tool completes in the Completion message field. For example, users can see "Querying knowledge graph" when the tool is in progress and "Query complete" when the tool is done.

Result

You have added a Knowledge Graph tool to your AI agent with the appropriate query instruction, execution mode, output settings, and processing messages configured.
