What
When a name matches more than one agent, the error now distinguishes several teammates sharing the name from a name that matches both a teammate and a background agent, and tells you to use the full name@team agent ID or the task ID.
Details
The name resolver also reports whether any of the ambiguous candidates is still running.
Evidence
Use the full agent ID (name@team) for the teammate or the task ID for the background agent.
