Copilot Studio agent memory needs separation, control and verification

Diesen Beitrag auf Deutsch lesen

Copilot Studio stores agent memories per user, lets makers enable Memory, and requires testing for stale recall, hallucination and appropriate abstention.

TL;DR

Copilot Studio Memory can be enabled from the Build tab. It captures relevant context, stores it as files in a dedicated Microsoft-managed folder for each user and agent, then applies it in later interactions. Users can inspect, update or clear memories through chat or a memory portal, while teams test recall and hallucination risks.

Governance takeaway

  • Makers: Enable Memory from the Build tab only when the agent needs continuity, then account for how captured context will influence later responses.
  • Admins/CoE: Confirm that each user has a separate memory folder and that users can inspect, update or clear their own memories through chat or the memory portal.
  • Security/Compliance: Treat memory as a quiet risk surface and validate stale recall, negative recall, abstention and hallucination before widening use.
  • Leadership/Business: Measure whether memory improves recall without reducing the agent's willingness to say it does not know.

Frequently asked questions

How does Copilot Studio store agent memory for individual users?

Copilot Studio stores each user’s memories as files in a dedicated folder within Microsoft-managed storage for that agent. Other users and the maker cannot view them.

How can users review or clear Copilot Studio agent memories?

Users can review or clear memories through the memory portal. In chat, they can also ask the agent to describe, update or forget stored information.

What should teams test before expanding Copilot Studio Memory?

Teams should test recall, negative recall, abstention and hallucination. Memory should improve later recall without making the agent confidently repeat stale information or invent details.
