Agent Island Tracks Six AI Coding Sessions From a Single Menu-Bar Icon

Agent Island is a monitoring tool designed to manage multiple simultaneous AI coding-agent sessions — such as Claude Code and Codex — through a single menu-bar icon. The tool addresses a core challenge: determining which session needs a human response, which is still producing output, and which completions belong to child agents rather than main threads. It groups sessions by provider and identity, filters out internal or automated runs, and assigns each visible thread a priority state — from unacknowledged user turns down to idle — so the most actionable session surfaces first. To avoid missed updates, Agent Island combines filesystem event triggers for speed with a six-second polling timer for recovery after sleep or watch restarts. The tool reports only observable session state and does not attempt to restart tasks or interpret the underlying work being performed.
