Agent Island: macOS notch-based workspace for managing local AI coding agent sessions

The article introduces a developer-built macOS utility called Agent Island designed to improve the workflow of users running multiple local AI coding agents. The creator explains that while tools such as Codex, Claude Code, Gemini CLI, Cursor Agent, and terminal-based agents are increasingly useful for coding tasks, managing them simultaneously can become chaotic. Each agent typically runs in its own terminal session, has separate approval prompts, independent history, and different waiting states, which can lead to missed decisions or blocked workflows if the user is not actively monitoring each one.

To address this issue, the developer created Agent Island, a lightweight macOS application that turns the system’s notch area into a centralized workspace for tracking AI coding agents. Rather than being another coding agent itself, it functions as a visibility and coordination layer that sits above existing tools. It displays active sessions in a compact interface, surfaces approval requests and plan-review prompts more quickly, and helps users return to the correct context without manually searching through multiple terminal windows.

The design choice of using the macOS notch is intentional, as it is a naturally visible and frequently observed part of the screen. This allows users to monitor agent activity without opening additional windows or disrupting their workflow. The tool is aimed at improving situational awareness when working with long-running or asynchronous AI coding tasks.

For distribution, the Mac App Store version is sandboxed and focuses on safe monitoring and review functionality. A direct download version includes a 7-day trial, with a Pro license available for a one-time payment of $19.99 per Mac. The project is presented as a response to growing complexity in multi-agent AI development workflows.
