          The Nook watches eighteen coding agents in one place — your menu bar and

          Each agent reports its own set of events. "Allow / Deny from a card"
          means the agent hands the decision to The Nook while it waits;
          "Observe" means every event still appears live, but the agent keeps
          its own prompting. Agents can run on this Mac or on remote machines
          over SSH — remote sessions report into the same grid. Muse, Cline and
          Amp run on this Mac only.
