Saving Subagent Output as a variable

Posted on by CU30050819-1

Hi everyone,

I have a question about variables storage. My flow is leveraging a subbagent whose output is really important and which I would like to be saved. Nonetheless, skimming through documentation; I have seen that while this is perfectly feasible for generative answers, this is not the case for a subagent per se.

Is there any way in which such output could be saved in a variable for subsequent storage, like in the attached screenshot? I would really appreciate some guidance on this matter!

You don't need to abandon the subagent approach. Configure explicit outputs on the subagent and consume those outputs in the parent agent. If you're trying to capture an arbitrary final response generated by the subagent's orchestration layer, that is different and isn't reliably exposed as a normal variable; in that case, redesign the subagent to return the information you need as an explicit Text or structured output.

Hi @CU30050819-1,

In the subagent, go to Settings > Agent outputs and define a Text output variable (e.g. OutputResult). At the end of the subagent's topic or flow, set that output variable to the value you want to return.

then the parent agent, after the subagent node, the output variable becomes available as a topic variable you can reference. Use a Set variable node to store it in a global variable if you need it across multiple topics:
Set(Global.SavedOutput, SubagentName.OutputResult)

This is the only supported way to pass structured data from a subagent back to the parent. The free-form conversational response the subagent generates isn't directly capturable as a variable, only explicitly defined output parameters are.
