Choose Copilot Studio harnesses by identity, predictability and cost
Diesen Beitrag auf Deutsch lesen
Use organisation identities, DLP and least privilege for autonomous agents. Match deterministic work to the standard harness and exception handling to the Microsoft Copilot harness.
TL;DR
Copilot Chat, Agent Builder and Cowork run on an individual user's identity, while Copilot Studio harnesses create organisation agents with separate publishing, DLP and ALM. Use the standard harness for deterministic workflows and the Microsoft Copilot harness for reasoning-heavy exceptions. Autonomous and recurrence-triggered flows consume Copilot Credits.

Governance takeaway
- Makers: Choose the standard harness when the same input must produce the same output, and reserve the Microsoft Copilot harness for exceptions requiring reasoning.
- Admins/CoE: Build organisation-owned licence-review workflows with Dataverse, DLP and ALM instead of relying on one person's Cowork.
- Security/Compliance: Prevent protected-group licence changes through the agent account's permissions, because instructions and failed hooks are not sufficient safeguards.
- Leadership/Business: Compare Copilot Credit costs with licence savings before automating a licence review.
Frequently asked questions
How do Copilot Studio standard and Microsoft Copilot harnesses differ?
The standard harness follows maker-defined topics, tools, flows and variables. The Microsoft Copilot harness plans its own route, retains memory and handles errors.
Can a Copilot Studio hook be the only protection against protected-group licence removals?
No, a hook cannot be the only safeguard because a failed hook lets the action proceed. The agent account should lack permission to change licences for protected groups.
When does a Copilot Studio licence-review flow consume Copilot Credits?
A recurrence-triggered or autonomous flow consumes credits at the standard rate. The zero-rated flow case requires a licensed user interacting through the agent trigger.
