All done. **29 pass, 0 fail** across 29 test cases.

**BDD workflow completed:**

1. **Discovery** — identified 7 categories of scenarios: valid kebab-case, empty/whitespace, hyphen placement, uppercase, leading digits, special characters (6 types), and boundary/defensive cases.

2. **Formulation** — wrote `isValidSkillName.test.ts` with 29 `describe`/`test` blocks, each annotated with `// Given / // When / // Then` comments following the BDD convention.

3. **Automation** — implemented `isValidSkillName.ts` with the regex `/^[a-z][a-z0-9]*(-[a-z0-9]+)*$/` plus a `typeof` guard against non-string inputs.

**Result:** `result.txt` written with full pass/fail summary.
