Variables allow you to store and use data that your agent extracts through the execution of the agent.

​
Variable Operations

​
Creating Variables

Variables are automatically populated when creating extraction blocks through the Recursion Agent or executing existing extraction blocks.
Runtime variable extraction example
Populated variables are added into the Variables tab in the Builder after execution.

​
Referencing Variables

Variables can be referenced to the AI Assistant or directly in prompts using {variable_name} syntax. Note, however that that workflow blocks can only reference variables populated by extraction blocks that are executed prior to the workflow block.

​
Referencing Variables in For Loop Blocks

For loop variable example
During iteration, use the variable name assigned to the name field in the for loop block to reference the current item in the loop.
  • {item.value} represents the current item’s value
  • {item.key} represents either:
    • The object property name when iterating over an object
    • The numeric index (0, 1, 2, etc.) when iterating over an array
When these references are used, they will be automatically resolved to their current values during agent execution.
