Skill Creator

This is meta-tooling for building other skills. It walks you through the full lifecycle: drafting a new skill from scratch, writing test prompts, running evals to measure performance, then iterating based on qualitative feedback and quantitative benchmarks. It also handles optimizing skill descriptions for better triggering accuracy, which matters since Claude tends to undertrigger skills by default. The workflow is flexible enough to meet users where they are, whether they're starting from zero or already have a draft that needs tuning. One thing that stands out is the attention to progressive disclosure, keeping skills under 500 lines and offloading detail to bundled resources so context doesn't bloat unnecessarily.
