+#!/bin/bash
+# slskd auto-disconnect
+# Disconnects from Soulseek after a period of inactivity to avoid
+# sharing files 24/7. Runs via cron every 5 minutes.
+#
+# Activity is detected by:
+#   1. Active downloads in progress via the API
+#   2. Recent log activity (searches, browsing, downloads) in docker logs
+#
+# Uploads do NOT reset the idle timer, but an in-progress upload will
+# delay disconnection until it finishes.
+#
+# Environment overrides:
+#   SLSKD_IDLE_TIMEOUT  - minutes before disconnect (default: 30)
+#   SLSKD_GOTIFY_TOKEN  - Gotify app token for notifications (optional)
