Get Flow Variable
Access and retrieve variables from your flow, enabling dynamic and context-driven automation in your workflows.
Component description
How the Get Flow Variable component works
Get Flow Variable Component
The Get Flow Variable component is designed to retrieve the value of a specific variable from the flow parameters within your AI workflow. This component acts as a utility tool, allowing other components or agents in the workflow to dynamically access and utilize variables that have been set earlier in the process.
Purpose and Functionality
This component is particularly useful when building modular and dynamic AI workflows. By enabling access to variables stored in the flow, it allows for more flexible decision-making, conditional logic, and data reuse across different stages of your automation or AI process. For example, you might want to retrieve a user’s previous input, a configuration parameter, or the result of a prior computation.
Inputs
The component exposes several configuration fields:
| Field | Type | Description | Required | Advanced |
|---|---|---|---|---|
Input Variable Name (variable_name) | String | The name of the variable you wish to retrieve from the flow. | No | No |
Tool Name (tool_name) | String | Internal name for referring to the tool in agent-based workflows. | No | Yes |
Tool Description (tool_description) | String | Description to help agents understand how to use the tool. | No | Yes |
Verbose (verbose) | Boolean | Whether to print verbose output for debugging or tracing. | No | Yes |
Input Details
- Input Variable Name is the main field you’ll use. Enter the exact name of the variable you want to access.
- Tool Name and Tool Description are optional and generally used for documentation or when integrating with agents that leverage tool metadata.
- Verbose can be toggled on to output detailed logs, which may be helpful for debugging complex flows.
Outputs
When the component runs, it produces several possible outputs:
| Output Name | Type | Description |
|---|---|---|
| Variable Value if exists | Message | The value of the requested variable if it exists. |
| Variable does not exist | Message | An indicator/message that the variable was missing. |
| Tool | Tool | The tool instance itself, for agent workflows. |
- Variable Value if exists: Returns the current value of the variable you asked for.
- Variable does not exist: Informs you that the requested variable was not found in the flow.
- Tool: Provides the tool object, which can be used by agent-based workflows that need to interact with or understand the capabilities of the component.
Why Use This Component?
- Dynamic Data Retrieval: Access and reuse values set earlier in your workflow without hardcoding them.
- Error Handling: Easily detect when expected variables are missing, enabling robust workflow logic.
- Agent Interoperability: Supplies metadata and tool objects to facilitate agent-driven workflows or tool orchestration.
- Debugging Support: Optional verbose output can help you troubleshoot workflow execution.
Typical Use Cases
- Passing user input or computed values between steps in a conversational AI.
- Checking for the existence of configuration or context variables before taking actions.
- Supplying agents with access to relevant parameters as they plan or execute tasks.
By integrating the Get Flow Variable component, your workflows become more adaptable, maintainable, and capable of handling complex scenarios where context and data persistence are crucial.
There are no examples of flow templates available at the moment using this component.
Frequently asked questions
- What does the Get Flow Variable component do?
It allows you to retrieve a specific variable or value previously set in your workflow, so you can use that information in later steps of the flow.
- When should I use Get Flow Variable?
Use this component whenever you need to reference or reuse data created or modified earlier in your workflow, such as user inputs, calculated values, or results from other components.
- What happens if the variable does not exist?
If the variable is not found, the component will provide a separate output indicating that the variable does not exist, allowing you to handle such cases in your workflow logic.
- Is this component essential for dynamic workflows?
Yes, retrieving and using variables is crucial for building flexible and context-aware automations, making this component a key part of advanced flow designs.
