dag node

Discover and inspect the node types available in your installation. Use these subcommands to explore what each node does, what ports it exposes, and how to wire it into a pipeline.

dag node list

Print all registered node types grouped by category.

bash

dag node list

dag node example <type>

Generate a minimal, runnable DAG JSON file that exercises the specified node type. The output is printed to stdout and can be piped into a file or passed directly to dag run.

bash

dag node example llm-text-anthropic

json

{
  "dagId": "llm-text-anthropic-example",
  "nodes": [
    { "id": "input",  "type": "input" },
    { "id": "llm",    "type": "llm-text-anthropic" },
    { "id": "output", "type": "text-output" }
  ],
  "edges": [
    { "source": "input", "target": "llm"    },
    { "source": "llm",   "target": "output" }
  ]
}

Save and run immediately:

bash
