Read the case’s method and prerequisites
Prerequisites: accessible n8n instance; OpenAI API key (for chat completions and embeddings). After importing the template, replace the example URL in the HTTP Request node with a real FAQ endpoint, run the manual ingestion flow once to populate the vector store, then enable the Chat Trigger for conversational testing. The in-memory vector store is volatile and will be lost on n8n restart, requiring re-ingestion.

Sales, Marketing & SupportImport n8n template → configure OpenAI credentials → send technical requests via Chat Trigger → CTO (o3) analyzes and delegates to Architecture/DevOps/Security/QA/Backend/Frontend Agents (gpt-4.1-mini) → receive comprehensive technical deliverables
Read the case’s method and prerequisites
Prerequisites: accessible n8n instance with LangChain nodes enabled; OpenAI API key supporting o3 and gpt-4.1-mini; webhook capability for chat messages. Boundaries: this is an official n8n workflow template—import the workflow JSON and configure credentials per node. Specialist Agents use the n8n dynamic expression `={{ $fromAI(...) }}` in their prompt fields; the framework injects the user message at runtime, so these are not traditional static system prompts. Cost: o3 is used only for the CTO Agent's strategic decisions; specialists use gpt-4.1-mini to reduce cost (source claims ~90% reduction). Not tested by this site.
