Workflow Prompts and Knowledge
Each Agent node in a Workflow can have its own prompt and toolset, and the entire workflow can share a common knowledge base. This section explains how to configure both.
Configuring Prompts for Agent Nodes
Select any Agent node on the canvas to open its settings panel on the right side of the screen. Navigate to the Prompts tab within the panel.
System Prompt
The system prompt defines the Agent node's role, tone, and behavior. For example, a "Classifier" node might have the system prompt: "You are a support ticket classifier. Categorize the incoming message as Billing, Technical, or General." Write a focused prompt that tells the agent exactly what its job is within the broader workflow.
Welcome Prompt
The welcome prompt is an optional opening message that the agent sends when it is first activated. This is most useful on Conversational nodes where you want the agent to greet the user or explain what information it needs.
Adding Tools to Agent Nodes
Within the node settings panel, use the Tools dropdown to enable specific tools for that agent. You can give each Agent node a different set of tools — for example, a "Research" node might have web search enabled, while a "Formatter" node has no external tools at all.
Shared Workflow Knowledge
The Knowledge tab at the workflow level (accessible from the top toolbar) applies to all Agent nodes in the workflow. To add documents:
- Click the Knowledge tab.
- Click Upload Document.
- Select a PDF, DOCX, or TXT file from your computer.
Uploaded documents are automatically vectorized and indexed. Every Agent node in the workflow can retrieve relevant excerpts from these documents when answering questions or processing data. This is useful for grounding your entire workflow in a shared set of reference materials, such as a product manual or policy document.
