Building n8n workflows by hand means knowing hundreds of node schemas. LLMs hallucinate node configs unless they are grounded in the real schema.

“Ground the model in 794 real schemas and it stops guessing.”
01 the system
step 01
Three agents, one artifact
A natural-language enhancer sharpens the brief, the retriever pulls exact node schemas from pgvector, and the builder (Claude + Gemini) assembles JSON that validates against the real schema before it ships.

Hallucinated node configs
Unassisted LLMs invent plausible-looking n8n node parameters that fail on import.
resolutionIndexed all 794 node schemas into Supabase pgvector with OpenAI embeddings; the builder only sees retrieved, real schemas, and output is validated before delivery.
