A useful way to understand n8n is to separate the goal, the input, the model or tool, and the way the output is evaluated.
One important area is cost control. Define what a good result looks like before changing tools or settings, then test one variable at a time so you can tell what actually improved the outcome.
Another area is beginner tips. Keep examples of both strong and weak outputs, check important facts or generated code independently, and document settings that produce consistent results.
The main takeaway is that n8n becomes much more reliable when the workflow includes clear inputs, repeatable checks, and a way to learn from previous results.
