Done. Here's the summary:

**29 tests, 0 failures** across 7 scenario categories.

### Discovery
Examined the lythoskill codebase (skill names in SKILL.md files, Zod schemas, deck link.ts resolver) and extracted the implicit naming convention: lowercase kebab-case with `[a-z][a-z0-9]*(-[a-z0-9]+)*`.

### Formulation → `isValidSkillName.test.ts`
BDD-style tests with `// Given / // When / // Then` annotations covering:
- **7 valid**: basic kebab, single-letter, multi-segment, combo- prefix, digits, no hyphens, numeric segments
- **5 empty/whitespace**: empty, spaces, leading/trailing whitespace
- **4 hyphen placement**: leading, trailing, consecutive, lone hyphen
- **3 uppercase**: PascalCase, ALL-CAPS, mixedCase
- **2 leading digits**: starts with digit, purely numeric
- **6 special chars**: underscores, dots, punctuation, @, emoji, CJK
- **2 boundary**: long name, tabs-only

### Automation → `isValidSkillName.ts`
Single regex: `^[a-z][a-z0-9]*(-[a-z0-9]+)*$` — validates the full convention in one pass.
