Notifications are a daemon and desktop capability, not a configurable plugin slot. AO currently persists notifications for these lifecycle events:

a session needs input;
a pull request is ready to merge;
a pull request was merged;
a pull request closed without merging.

The desktop notification center provides Unread and All views, pagination, live updates, mark-read controls, and links to the related session or pull request. While the Electron app is running, new records can also appear as native app toasts.

Slack, Discord, generic webhook, Composio, OpenClaw, and standalone desktop notifier configuration from the legacy TypeScript release are not supported in the rewrite.

See notification center for the current behavior.
