skill-creator is a Claude skill that guides users through creating brand-new skills and iteratively improving existing ones. It walks through deciding what a skill should do, drafting its SKILL.md file, generating realistic test prompts, and running those prompts both with and without the skill to compare results. It supports building quantitative assertions, grading outputs, aggregating benchmark data, and launching a review interface so a person can give feedback before another revision pass. A separate procedure in the skill focuses on tuning a skill's description text so that Claude triggers it more reliably. It also covers packaging a finished skill into an installable file and adjusting the workflow for different environments such as Claude Code, Claude.ai, and Cowork.
