Two skills that teach Claude to spend tokens wisely: think-twice (pause before picking an approach) and surgical (build only what was asked). Up to 178x token savings, tested.
Two skills: think-twice forces Claude to check for existing APIs, packages, and simpler approaches before implementing. Surgical forces Claude to build exactly what was asked, nothing more. Tested savings: 178x on fake user profiles, 16x on bug fixes, 13x on currency conversion, 6x on city autocomplete, 5x on rate limiting.
