If you run several Claude Code sessions at once, you know the rhythm: an agent stops, waits for a permission, and you only notice minutes later. Nuza Notch turns the MacBook’s notch into a dynamic island for agent sessions, so the machine’s dead pixel real estate becomes the control tower.
- Every live Claude Code session surfaces in the notch with its status.
- Permission prompts and questions render as cards you answer in one tap.
- Jump-back lands you on the exact Terminal tab that asked.
The design rule I care most about: it fails open. If the app breaks, crashes, or gets confused, Claude just prompts normally in the terminal like the app never existed. A helper that can block the thing it helps would be worse than no helper.
Swift and SwiftUI, MIT licensed, shipped after a 28-agent build weekend. The gate before calling it done: the full 137-test suite twice, end-to-end twice, all green. Story in the journal.
