The Nook watches thirteen coding agents in one place — your menu bar and notch show every session that is running, thinking, or blocked, and a card answers permission prompts without leaving your keyboard.
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.
