When working with agentic workflows, expressions used in branching, looping, and data mapping must follow a defined syntax. This structure also applies to the generated data map within the model. Below are the keywords and reference patterns used in agentic workflow expressions:
  • Refers to the top-level agentic workflow context:
    Python
    flow
  • Refers to the parent context, equivalent to the top-level agentic workflow for nodes within it:
    Python
    parent
  • Refers to the current node:
    Python
    self
  • Refers to inputs and outputs of the current agentic workflow within agentic workflow nodes:
    Python
    parent.[input|output].<name>
parent.[input|output]["<name>"]
  • Refers to the current index in a foreach loop, returns null if not in a loop:
    Python
    parent._current_index
  • Refers to the current item in a foreach loop, returns null if not in a loop:
    Python
    parent._current_item
  • Refers to inputs and outputs of other nodes within the current agentic workflow:
    Python
    parent.<nodeName>.[input|output].<name>
parent["<nodeName>"].[input|output]["<name>"]
  • Refers to inputs of the current node:
    Python
    self["input"].<name>
self["input"]["name"]
