Chrome Tab Watchdog
Conservative Chrome tab cleanup with in-process observation and browser-call leases.
Good to know before installing
Runs a background thread inside Hermes that proxies your local Chrome DevTools port (127.0.0.1:9222 → 127.0.0.1:9223, loopback only, you must point browser.cdp_url at it), injects a focus/activity listener into every Chrome page, rewrites browser_exec session names to a per-profile namespace, and a cron script you schedule auto-closes idle, duplicate and blank tabs (including tabs with unsaved text).

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install chrome-tab-watchdog - Said no? Turn it on later:
hermes plugins enable chrome-tab-watchdog - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
