Delegate agent tasks using child agents in Copilot Studio: Review

The whole concept of 'child agents' sounded like a recipe for over-engineering, maybe just a bunch of abstract diagrams and enterprise jargon. But it's not. It's just a function call, but for a chatbot.

I needed this because the last agent I built became a monolithic nightmare of branching topics that nobody could debug. This module shows you how to break off a specific task—like handling returns or checking order status—into its own self-contained agent. The parent agent just routes the request and gets a result back. Simple. The walkthrough for setting up inputs and outputs between the two was clean. It actually worked, which is more than I can say for some of these docs-as-a-course modules.

My only real complaint is the sterile example. Passing a single text string is trivial. Try passing a JSON object with optional fields and see how fast the pretty UI gets complicated. The module avoids that mess entirely. It also doesn't touch what happens when the child agent fails or times out. In my world, that's 90% of the job. But for what it is—a quick tutorial on structuring things inside Copilot Studio—it's solid. It gave me a concrete pattern to refactor my mess, and that's worth an hour.
