Prompt Node

The Prompt node is a structured text input. You type instructions once, and downstream generation and processing nodes consume that text through a connection. It is the usual way to start a workflow with words rather than a model call.

What it stores

• A single prompt string field holding the authored text.
• The node starts empty. There is no model, provider, or parameter configuration on a Prompt node.

Authoring a prompt

1. 1

   Add a Prompt node

   Add a Prompt node from the canvas toolbar. A freshly spawned node shows a placeholder, “Describe what you want to create...”, with a brief shimmer to draw your attention to the input.

2. 2

   Type your text

   The body is a multi-line text area. Edits are saved to the node's promptfield as you type. When you do not have edit access, the node shows “View only” and the input is read-only.

3. 3

   Connect it downstream

   Drag from the Prompt node's output port to a generation node's prompt input. The footer shows a connection count once the node has at least one outgoing edge.

Ports and execution

The Prompt node runs locally — it does not make a network request. When the workflow executes, the node reads its text and emits it on the text-out port as a text value. Downstream nodes receive it on their prompt input (for example, prompt-in on Text Generation).

• Whitespace-only text is treated as empty. If the resolved text is empty at execution time, the node fails with “Prompt node has no text content.”
• The executor trims the text before emitting it.
• If a value arrives on the node's own prompt input port, that connected value takes precedence over the stored field, followed by any expression input, then the stored prompt field.
