Claude Project Instructions Discourage Code Nodes

[hueyfreemanwasright]

Why do the claude project instructions discourage code node use?

It states "## Key Insights

• USE CODE NODE ONLY WHEN IT IS NECESSARY - always prefer to use standard nodes over code node. Use code node only when you are sure you need it."

I find this strange because code nodes seem very helpful and precise. Why is the n8n MCP discouraged from using them?
