+description: Send system notifications to specific Clawdis nodes (macOS computers) via the Gateway and CLI. Use when you need to alert a person or confirm a remote action on a particular machine, or when an agent must push a notification to another computer.

+
+# Clawdis Notify
+
+## Overview
+
+Send local notifications to a specific Clawdis node (currently macOS only) via the Gateway CLI.
+
+## Quick start
+
+1) Find a target node.
+```bash
+clawdis nodes status
+clawdis nodes describe --node <idOrNameOrIp>
+```
+
+2) Send the notification.
+```bash
+clawdis nodes notify --node <idOrNameOrIp> --title "Ping" --body "Gateway ready"
+```
+
+## Core command
+
+`clawdis nodes notify --node <idOrNameOrIp> [--title <text>] [--body <text>] [--sound <name>] [--priority <passive|active|timeSensitive>] [--delivery <system|overlay|auto>]`
+
+Notes:
+- Provide at least one of `--title` or `--body`.
+- `--delivery` defaults to `system`.
+- Only macOS nodes expose `system.notify` right now.
+- Notification permission must be granted in the macOS app or the command fails.
+
+## Multi‑computer usage
+
+Pick a specific node by id/name/IP, or iterate across nodes:
+
+```bash
+for node in $(clawdis nodes status --json | jq -r '.nodes[].id'); do
+  clawdis nodes notify --node "$node" --title "Heads up" --body "Maintenance in 5 minutes"
+done
+```
+
+## Troubleshooting
+
+- `nodes notify failed: ...` usually means the node is offline, not paired, or missing permission.
+- If the Gateway is down or unreachable, notifications cannot be delivered.
+
+## Low‑level fallback (rare)
+
+If needed, use raw invoke:
+```bash
+clawdis nodes invoke \
+  --node <idOrNameOrIp> \
+  --command system.notify \
+  --params '{"title":"Ping","body":"Hello","sound":"Glass","priority":"active","delivery":"system"}'
+```
