FAQ
What is Agent Island?
An open-source status companion for your AI coding agents on macOS and Windows — Claude Code, Codex, Antigravity, Grok, and Cursor. It shows live session state, calls you when a turn is yours, and keeps quota and cost in view, all computed locally with no Agent Island account or product telemetry. Read how the Claude Code status monitor distinguishes working, waiting and stalled sessions.
Does it run in the cloud?
No. It runs on your machine, reads the transcript files your tools already write to disk, and calls the official usage APIs with the tokens you already have locally. No account, no telemetry.
How do I install it?
macOS, one line: brew install tristan666666/tap/agentisland — or grab the DMG from the latest GitHub release. Windows: download the AgentIsland win-x64 zip from the same releases page, unzip, run AgentIsland.exe.
Is there a Windows version?
Yes. Agent Island ships a native WPF build for Windows 10/11. As of v2.1.2 both platforms ship from the same tag — same five providers, same live session state, same report cards; the capability matrix separates released code from the UI paths independently rerun on Windows. Download it from the GitHub releases page.
Why does macOS warn me on first launch?
The app is ad-hoc signed (no paid Apple Developer account), so macOS asks for one right-click → Open the first time. Updates are independently verified: Sparkle checks an EdDSA signature before installing anything.
What's on the weekly report card?
Total tokens with an API-value estimate, a Claude-vs-Codex faction duel sitting at your real usage split, 7-day bars with a TOP-3 model donut, and your island rank. The image is rendered locally and shared only when you choose to copy or share it.
How do I report a problem?
Open a GitHub issue with your OS version, app version, Claude Code or Codex version, and the state that looked wrong.
