Loop Node
In many workflow scenarios, you'll find yourself needing to perform the same task multiple times with different inputs - like writing social media posts for multiple product features or analyzing feedback from different customers. The Loop Node is designed exactly for these situations, making it easy to process a list of items without creating redundant workflow steps.
What is a Loop Node?
A Loop Node is a specialized component that automates repetitive tasks by:
- Taking a list of items as input
- Using a designated agent to process each item
- Following specific instructions for handling each item
This creates an efficient system for handling multiple similar tasks without creating separate nodes for each item.
When to use a Loop Node?
Consider using the Loop Node when:
- You have a list of similar items that need the same processing
- A task needs to be repeated multiple times with different inputs
- You want to automate repetitive operations
- You need to process data in batches
- You want to maintain consistency across multiple outputs
Here are some common scenarios where Loop Node excels:
| Scenario | Example |
|---|---|
| Content Creation | Processing a list of blog post ideas to generate full articles for each topic |
| Social Media | Creating LinkedIn posts for multiple product features or announcements |
| Data Processing | Analyzing customer feedback from multiple sources using the same criteria |
| Documentation | Generating documentation for multiple API endpoints following the same template |
How a Loop Node Works
The Loop Node operates through a systematic process:
- Extracts a list of items from some source, which can be a human input, a previous node output, or both
- Processes each item individually using the configured agent with the same instructions
Configuring a Loop Node
To set up a Loop Node, you need to configure these three essential components:
1. The List Setup
The first thing you'll see when creating a Loop Node is the "For each item in" field. This is where you specify your list of items to process. You can reference a human input or a previous node output via variables. The system will automatically handle converting your input into a processable list.
2. Agent Selection
Next, you'll choose an agent to process each item in your list:
- Click "Select an agent" to choose from your available agents
- Pick an agent with expertise relevant to your task
- The same agent will process each item in your list
3. Instruction Configuration
In the "Task" field, write instructions for how the agent should process each item:
- Be clear and specific about what you want the agent to do
- Use variables to reference human inputs or previous node outputs if needed
- The system will automatically apply these instructions to each item in your list
4. Processing Limits
For workflow efficiency and resource management:
- Use the "Max items to process" slider to set a limit
- The default maximum is 10 items
- Adjust based on your needs while considering processing time and resources
