Start Node (type = "start")

Defines the input schema of a workflow.

Schema

• See: StartNode.json
• Key field:
  • data.outputs: JSON Schema describing the input fields exposed by the workflow

Typical usage

• The execution API maps the request body into the context fields defined by Start’s outputs.
• Subsequent nodes access them via ref syntax (for example ["start_0", "query"]).

Example

Minimal Start → End workflow (receive query and output it as result):
