Steps

1. Import the workflow template

   In the n8n editor, click the upper-right menu → Import → Import from file, and select workflow.json. After import you should see 18 nodes: 1 Chat Trigger, 1 AI Agent (Director), 6 AI Agent Tools (specialists), 7 OpenAI Chat Model nodes, 1 Think Tool, and 2 Sticky Notes.

2. Configure the director layer (entry and strategy)

   Locate the 'When chat message received' node and confirm the webhook path (default: creative-webhook-id; change if needed). Then configure the 'Creative Director Agent' node: connect its language model to 'OpenAI Chat Model Director' with model set to o3. Connect the 'Think' tool node's ai_tool output to the Director Agent's tools input so the Director can plan and reason.

3. Configure the 6 specialist designer agents

   Inspect the following 6 AI Agent Tool nodes. Confirm each node's text field is `={{ $fromAI('Prompt__User_Message_', ``, 'string') }}` and connect each one's language model input to its corresponding OpenAI Chat Model node (model fixed to gpt-4.1-mini). The toolDescription fields are pre-filled with role definitions and should not need modification: - Graphic Designer: visual identity, logos, print, packaging - UI/UX Designer: interface design, prototyping, interaction - Brand Strategist: positioning, market research, competitive analysis - Creative Copywriter: copy, taglines, brand messaging - Motion Graphics Designer: animation, promo videos, dynamic visuals - Web Designer: websites, responsive layouts, accessibility

4. Add credentials and activate for testing

   Add an OpenAI API key in n8n's Credentials page. Return to the workflow and select that credential for all OpenAI Chat Model nodes. Save, then click Activate to bring the Chat Trigger online. Send a message via the built-in n8n chat or externally to the webhook URL, e.g. 'Design a brand identity for a sustainable clothing startup'. Verify that the Director invokes multiple specialists and returns a combined creative package.

Please set up this n8n workflow as an AI creative design agency simulation. Core requirements: 1) Chat Trigger receives design briefs; 2) Creative Director Agent uses o3 for strategic planning; 3) Think tool assists decision-making; 4) Director delegates to 6 GPT-4.1-mini specialist agents (Graphic/UI/UX/Brand/Copy/Motion/Web); 5) Each specialist's toolDescription defines its domain. First confirm n8n instance availability and OpenAI API key permissions, then import the JSON and verify node connections.
