Included in this chapter:

  • The agent already exists, so the work is the seam
  • Four preconditions, and what each one gates
  • Preparing the target agent to accept connections
  • Adding the connection, field by field
  • The routing description is a local copy
  • Deciding what crosses to the connected agent
  • What the latest published version means, and where
  • Suspending, removing and watching the connection
  • How these choices show up in questions

The four preconditions: where each one is set and how it fails

PreconditionWhere it is setWhose job it isWhat you see when it is missing
Same Power Platform environmentNot a setting: a property of where each agent was created or importedWhoever owns the ALM path for the two agentsThe agent is absent from the list of available Copilot Studio agents
The other agent is publishedThe specialist's own Publish actionThe specialist's ownerNot connectable at all, and later in its life, unpublished changes the main agent never sees
Connections from other agents allowedLet other agents connect to and use this one, on the specialist's Settings pageThe specialist's ownerThe agent does not appear in the connection list even though it is published in the same environment
Owner or shared access for the makerAgent sharing, from the specialist's three dots menuThe specialist's ownerMicrosoft states the requirement without naming a symptom: the maker is simply not permitted to make the connection
End users can reach the connected agent at runtimeAgent sharing again, depending on the authentication setupThe specialist's owner, once the main agent's audience is knownDepending on the authentication setup, end users may not be able to access the connected agent at runtime
