I've been writing Claude Code skills for the past year and kept making the same mistakes: wrong frontmatter format, first-person descriptions, abstract examples instead of concrete input/output pairs.
Good examples exist everywhere, but they are scattered. So I extracted what has worked best for me, combined with Claude's own best practices, and built a generator.
The tool: 1. Takes a plain English description of your expertise 2. Generates a skill following Claude's official format 3. Grades it on a 100-point rubric and gives specific suggestions
Grading criteria includes: format compliance, conciseness (Claude is smart, don't over-explain), Quick Start quality, example concreteness, and completeness.
Tech: Next.js, Claude API, Supabase, v0.

This is v1. I'd love feedback on what's working and what needs improvement.
