Nodes

Overview

The Nodes skill lets you control remote companion devices connected to the Suzent server. Nodes connect via WebSocket and advertise capabilities (commands) you can invoke.

In sandbox mode, the suzent CLI is not available. Use the REST API via $SUZENT_BASE_URL.

Use this skill to:

• Discover connected devices and their capabilities
• Run commands on remote devices (take photos, run scripts, get clipboard, etc.)
• Check device connectivity status

Sandbox API (preferred)

Endpoints

Basic usage (Python)

import os
import requests

base = os.environ["SUZENT_BASE_URL"]

# 1) List nodes
nodes_resp = requests.get(f"{base}/nodes", timeout=30)
nodes_resp.raise_for_status()
nodes = nodes_resp.json().get("nodes", [])

if not nodes:
    print("No nodes connected")
else:
    # 2) Choose a node (usually by display_name)
    node = nodes[0]
    node_id = node["node_id"]

    # 3) Inspect capabilities
    detail_resp = requests.get(f"{base}/nodes/{node_id}", timeout=30)
    detail_resp.raise_for_status()
    detail = detail_resp.json()

    # 4) Invoke command
    invoke_resp = requests.post(
        f"{base}/nodes/{node_id}/invoke",
        json={"command": "camera.snap", "params": {"format": "png"}},
        timeout=60,
    )
    invoke_resp.raise_for_status()
    result = invoke_resp.json()
    print(result)

Finding a node by name

Endpoints accept either node_id or display name. Resolving the node first via GET /nodes is still recommended when names may be ambiguous:

target_name = "MyPhone"
target = next((n for n in nodes if n.get("display_name") == target_name), None)
if not target:
    raise RuntimeError(f"Node not found: {target_name}")
node_id = target["node_id"]

Host mode CLI (fallback)

If you are running on host and the CLI is installed, these commands are still valid:

suzent nodes list
suzent nodes status
suzent nodes describe <node_id_or_name>
suzent nodes invoke <node_id_or_name> <command> key=value [key2=value2 ...]
suzent nodes invoke <node_id_or_name> <command> --params '{"key": "value"}'

Examples

# Sandbox-safe invocation example
result = requests.post(
    f"{base}/nodes/{node_id}/invoke",
    json={"command": "speaker.speak", "params": {"text": "Hello world", "prompt": "cheerful"}},
    timeout=60,
).json()

Best Practices

• Always list nodes first and verify capabilities before invoking.
• Prefer selecting by display_name, then use the resolved node_id for API calls.
• Keep command params JSON-serializable and explicit.
• Handle the case where no nodes are connected gracefully.
• Nodes require the Suzent server to be running.
