Agent Get Variable
Variable source: set variable_name via the node’s inline text field or wire a STRING into the variable_name input. Output: value (ANY, or null if unset). A 🔑 button in the left toolbar adds this node to the canvas.
Tip: In the Agent Settings dialog (gear icon), you can add a variable using the inputs under the Variables section. Pressing Save also persists a filled variable name/value pair along with the description. Reusing the same variable name overwrites the value.
