What a Dynamic Island should do on a Mac
On the iPhone, the island earns its space by showing live activities: the things changing in the background that you'd otherwise check on. macOS doesn't ship an equivalent, and for a developer, the background activity worth watching is agents. AgentPeek applies the island idea to exactly that: a compact pill under the notch with glanceable status, expanding into live sessions, prompts, and usage the moment something needs you, then collapsing again.

One job: your agents
Most Mac notch apps are general-purpose: music controls, file shelves, battery HUDs. AgentPeek does none of that. It spends the notch on Claude Code, Codex, Cursor, and nine more coding agents: their sessions, their permission prompts, their questions, their token usage, plus your local dev servers. If you want album art in your notch, AgentPeek is the wrong app; if you want to stop alt-tabbing to check on agents, it's the right one.

Native, shaped to your notch
AgentPeek is a native macOS Swift app. The island never steals focus, and Appearance settings shape it to taste: expanded and collapsed widths, density, glass opacity, what the collapsed pill shows, per-tool colors. Auto-expand opens it when an agent needs you; hide-when-idle keeps the notch bare between runs. On a Mac without a notch, menu bar mode carries the same live numbers.
