SC-003: Validation Fails When Frontmatter Missing Description

Covers: FR-001, FR-011, FR-012 — Generated SKILL.md MUST have valid frontmatter; Validation MUST check description length Type: Failure

Given

  • A skill directory test-skill/ exists with a SKILL.md that has frontmatter missing the description field: 
    ---
name: test-skill
---

When

  • The validation function validate_skill("test-skill/") is invoked

Then

  • The validation result valid is False
  • The errors list contains a message indicating the description field is missing

Verification Method

Method: Automated test

Steps:

  1. Create a temporary directory test-skill/ with a SKILL.md containing only a name field in frontmatter
  2. Call validate_skill("test-skill/")
  3. Assert result.valid is False
  4. Assert any item in result.errors contains the substring description

Expected evidence: valid: False, errors list includes an entry like "Missing required field: description".
