It accepts a plain-text problem description via a POST webhook and uses an Azure OpenAI-backed AI Agent to decide whether the problem warrants a multi-agent workflow or a simpler single-flow automation.\n\nThe AI Agent applies structured decision rules: if the problem involves multiple independent reasoning steps — such as classification, validation, routing, or risk scoring — it designs a full multi-agent architecture with named agents, n8n node types, and logical flow. If the problem is simple, it recommends a minimal node list instead.\n\nThe raw AI output is then parsed to extract the decision, agent definitions, and workflow steps. Finally, a styled HTML report is generated and returned directly in the webhook response as a visual card-based dashboard.\n\n### Setup steps\n1. **Activate the workflow** in n8n to register the Webhook URL.\n2. **Configure Azure OpenAI credentials** — ensure the `Azure Open AI account` credential is valid and the `gpt-4o-mini` deployment is active in your Azure resource.\n3. **Send a POST request** to the webhook URL with body: `{ \"description\": \"Your problem description here\" }`\n4. The response will be a styled HTML page with the architecture decision and agent breakdown.\n\n### Customization\n- Replace `gpt-4o-mini` with `gpt-4o` for higher reasoning accuracy on complex problems.\n- Modify the AI Agent system prompt to add new decision rules or output formats.\n- Update card styles in the **Build HTML Architecture Report** node to match your brand."},"typeVersion":1},{"id":"8fef77e7-2fd2-4ae8-9455-083f6bfe0588","name":"Sticky Note - Input Section","type":"n8n-nodes-base.stickyNote","position":[-448,384],"parameters":{"color":7,"width":388,"height":326,"content":"## 📥 Input & Extraction\nReceives a POST request with a `description` field and extracts the raw request body for downstream processing."},"typeVersion":1},{"id":"25685a95-fea8-49f1-8ccf-ff9d4130e7b1","name":"Sticky Note - AI Section","type":"n8n-nodes-base.stickyNote","position":[-32,384],"parameters":{"color":7,"width":432,"height":374,"content":"## 🤖 AI Architecture Decision\nThe AI Agent evaluates the problem description and decides if a multi-agent workflow is needed.
