What is Skill Creator?

Skill Creator is an official Anthropic skill for Claude that helps you create new skills from scratch, modify and improve existing ones, and measure their performance. It supports running evals to test a skill, benchmarking with variance analysis, and optimizing a skill's description so it triggers more accurately.
