UnverifiedA common mistake is tool-first, logic-later, that is, opening n8n and dragging nodes before the business logic has been defined.63% similarUnverifiedIn n8n's LLM node, how the system prompt is written directly determines whether the data received by subsequent nodes is well-structured and usable, making it the most technically demanding and most easily underestimated part of no-code building.62% similarUnverifiedWhen the number of tools increases and tools with similar names and overlapping functions appear (such as get_x, fetch_x, read_x), the LLM's tool selection becomes unreliable.61% similarUnverifiedThree bottom lines for error handling: if the LLM times out, the workflow must fail rather than silently publish an empty summary; retry counts must be capped and after final failure an alert must be sent with the execution link; each run must record the prompt version and model name.61% similarUnverifiedA "ghost document" phenomenon exists: outdated process descriptions may rank higher than the latest version due to their dense keywords, while the retrieval system cannot detect document expiration.60% similar
