Copilot Studio workflows put agent reasoning directly into the process

Diesen Beitrag auf Deutsch lesen

The new Copilot Studio workflow experience adds agent nodes, structured outputs, node testing and evaluations alongside deterministic actions.

TL;DR

Copilot Studio’s new workflow experience places an agent node directly on a visual workflow canvas alongside deterministic actions. Makers can use published or workflow-scoped inline agents, return structured outputs, request human assistance, test nodes in isolation and evaluate new inline agents with documented limits.

Why it matters

  • Makers: Build the deterministic backbone first, then add an agent node only where unstructured input or judgment exceeds fixed rules. Define the output schema before writing instructions so downstream steps can use fields directly.
  • Admins/IT: Choose the GitHub Copilot harness deliberately and budget for usage-based billing across building, testing, evaluating and runtime work. Treat workflow and MCP server tools for agents as preview capabilities when planning production designs.

Frequently asked questions

What agent choices are available in a Copilot Studio workflow agent node?

The node can call an existing published agent or create an inline agent scoped to that workflow. Inline agents are not reusable across workflows.

How does structured output improve Copilot Studio workflow steps?

Structured output exposes named fields as dynamic-content tokens, allowing later steps to branch on values or write them directly to Dataverse columns.

What limits apply to Copilot Studio workflow evaluations?

Evaluations apply only to new workflow-created agents, allow up to five AI-generated test methods and 20 evaluation runs per node daily. Custom models are unavailable.
