New Skill Creator

New Skill Creator scaffolds a new skill from a description of what it should do. It generates the SKILL.md with valid YAML frontmatter (the single most common reason skills are invisible to Claude Code is malformed frontmatter), creates the directory structure under .claude/skills/, sets up reference file stubs, and validates the output. The skill enforces two YAML rules learned after 37 of 52 skills broke simultaneously: never nest double quotes inside double-quoted strings, and every SKILL.md must start with a --- block containing a description: field. It also generates a test invocation prompt so you can verify the skill works before relying on it in production chains. Validation is a one-liner in Python that parses the frontmatter block.
