Keep your app true to your design

When one token points at another that was renamed or removed, or loops back to itself through a chain, the value your app gets is no longer the one in the design. This finds missing and circular aliases in a design token file before you build with it.

It reads tokens grouped as objects with a type and a value, the format shown in the design handoff worksheet. It checks that tokens exist and that whole-value aliases resolve; it is not a full validator for the token specification.

It runs from the command line and needs Python 3.10 or later. It pairs with the Turn a Figma design into a working page guide. Provider accounts, model weights, GPU compute and hosting are not included.
