Sharing an agent normally means sharing your screen: one person drives, everyone else watches a video of it, and the whole thing ends when the driver closes the laptop.
In Loopyard the agent is the shared surface. Every chat, terminal session, and service log has its own URL. Send the link and your teammate is in the same live session, not watching a recording of yours. They can type in the chat, run commands in the same terminal, and scroll the same logs. Three people can watch a flaky test get debugged at once.
Nobody is hosting. The server owns the session and streams it to everyone, so the state stays consistent and nothing depends on your laptop staying open. Close it and the work continues. Anyone with the link picks up where it is.
