FAQ
Agents & Workflows
Common questions about moving to the new agent and workflow model in Copilot Studio — when to upgrade, what to build on the GitHub Copilot harness, and where topics, prompts, adaptive cards, and child agents land.
Do I need to upgrade each and every agent?
If it does the job, don't rush into an upgrade. Standard agents already running in production can stay as-is; upgrade when there's a clear reason to.
Do I build every new agent on the GHCP harness?
If you want to automate with AI, you probably want a workflow with AI nodes. But if it's conversational and doesn't need to handle complex tasks, you can also build declarative agents in Agent Builder or Copilot Studio (the latter is upcoming).
What happens to topics? Are they coming back?
Not likely. The mental model: if topics are used to drive the conversational flows, then instructions and/or skills; if they are used to transform data, then code execution in the sandbox or workflows.
What happens to prompts?
Prompts are no longer the unit of work. In workflows, prompts become inline agents. In agents, the functionality of the prompt may be turned into a skill in most cases. Rethink what the workload needs and map it to the relevant component.
What happens to adaptive cards?
Rich UI component options in agents are still being actively worked on.
What happens to child agents?
We have a cleaner model now with connected agents: less overlap, and most of the role that child agents played can be covered by skills.
