# Flow Tools
## Introduction
**Flow Tools** are tools used to build and manage intelligent agent workflows, allowing developers to define multi-step task processes through visual interfaces or code. These workflows can include calling external APIs, processing data, executing logical decisions, and more, ultimately forming a complete automated task chain.
* **Visual Workflow Design**: Users can intuitively design each step and logic of the workflow via a drag-and-drop interface.
* **Multi-step Task Chains**: Supports defining multiple sequential or parallel task steps to implement complex business logic.
## Create a Flow Tool
First, select the **Tool** panel. Here, you can choose either **Create From Blank** or **Create From Template**. In this example, we’ll go with the first option — **Create From Blank**.
After clicking **Create**, you will be redirected to the **Tool Creation Panel**, where you need to configure the following information:
* **Avatar**\
The icon or image representing your tool. This helps visually identify the tool in the interface.
* **Name**\
The internal name of the tool. **Tool name can only contain letters, numbers, and underscores** (e.g., `my_custom_tool`). This name is used programmatically and must follow naming rules.
* **Display Name**\
The name shown to users, such as when the tool is used by an agent. **There are no restrictions on characters**, so you can use spaces, symbols, or non-English characters if needed (e.g., `My Custom Tool`).
* **Description**\
A brief explanation of what the tool does. This helps others (and yourself) understand the purpose of the tool at a glance.
* **Create Tool Type**\
Choose the type of tool to create.
After clicking **Create** in the creation panel, you will be redirected to the **Flow Tool Orchestration** panel. Here, you can customize your tool using a variety of powerful nodes—almost the same as in AgentFlow.
## Flow Tool Example
The following presents a simplified **Enhanced Knowledge Search Flow Tool** along with its implementation method. This tool
This flow tool, aside from the start and end nodes, uses only two core components:
An LLM node for extracting the query, and a knowledge search node for retrieving information from the WorkFX
The configuration of the LLM node is shown above. Users are free to customize it to enable more complex functionalities; this setup is for demonstration purposes only. The blue text indicates a reference to the query from the start node, which serves as the default input for the tool.
The configuration of the Knowledge Search node includes the following:
* **Knowledge Selection**: Choose one or more knowledge sources to define the search scope. In this example, the *WorkFX* introduction document is selected.
* **Search Parameters**: Configure the following parameters:
* **TopK**: Specifies the number of top relevant results to return.
* **Score Threshold**: Sets the minimum relevance score required for results to be considered.
* **Enhanced Domain Mode**:
* Optional feature;
* Improves retrieval performance when enabled;
* May result in slower responses and higher computational cost;
* Not enabled in this example.
In the End Node, select the `text` output from the **Knowledge Search node** as the final output
* This will pass the retrieved text to the user or downstream processes.
