Cut & Joint Cut List: a free Claude skill

A small skill that turns a simple project (box, shelf, bookcase, bench, frame) into a cut list and a board-foot or plywood estimate.

• Parts grouped by assembly
• Board feet with waste allowance
• Plywood sheet count with kerf

Made by Cut & Joint, part of What If Labs.
