This catches the usual React Flow footguns: nodeTypes defined inside components that cause every node to remount, missing memo wrappers that kill performance, and useReactFlow called outside the provider boundary. It walks through five review gates in sequence, from locating flow code to closing out checklists on performance and common mistakes. The real value is in the concrete antipatterns with file:line citations, things like inline callbacks breaking memoization and mutating node state directly. If you're code reviewing anything that uses @xyflow/react, this gives you a structured checklist so you're not just eyeballing for problems.
