DSH Turn Notifier

Chrome notification when a DeepSeek Harness (DSH) agent turn finishes on your machine. No tab kept open, no account.

DSH Turn Notifier tells you the moment a DeepSeek Harness (DSH) agent turn finishes, with a native Chrome notification — no pinned tab, no account, nothing to configure. HOW IT WORKS • A Manifest V3 service worker polls your local harness's own session-list endpoint on 127.0.0.1 every 5 seconds. • When the main (non-subagent) session flips from running to finished, a two-line notification appears: "DeepSeek", and under it the name of the conversation that finished. • A bundled chime plays with it, so you hear it even when macOS has Chrome's own notification sound muted. • Clicking the notification focuses your harness tab, or opens it if it is closed. • The toolbar icon doubles as a health light: clean while the local relay answers, badged when it does not. OPTIONS Sound on or off, whether the agent preset and working directory are appended, whether the notification stays on screen until dismissed, how often it checks, and whether it stays quiet while you are already looking at the harness tab. WHAT YOU NEED This is a companion tool for a harness running on your own machine. It reads turn state from a local relay at http://127.0.0.1:3098 and matches your harness GUI tab at http://127.0.0.1:3080. Both must be running on your machine for the extension to do anything; with neither running it stays idle. There is no remote service, no sign-in and no account. PRIVACY No data is collected, stored or transmitted. Every request the extension makes stays on 127.0.0.1. Your options are kept in Chrome's own settings storage and nowhere else. Not affiliated with, endorsed by or sponsored by DeepSeek. The name is used only to identify the local harness this extension works with.
