Conciseness

The body is only a heading and one sentence ('This skill tests that multiline YAML descriptions are normalized to single lines.') with no padding and no over-explanation of concepts Claude already knows, matching the lean score-5 anchor.

Actionability

It states a fact about what the skill tests but provides only a high-level hint with no concrete steps, commands, or examples for how normalization is performed, sitting just above the entirely-vague score-1 anchor.

Workflow Clarity

This is a simple single-purpose skill under 50 lines whose single action is unambiguous, and it involves no destructive or batch operation that would require validation, so the simple-skill exception yields a 5.

Progressive Disclosure

With under 50 lines, no need for external references, and a single well-organized section, the simple-skill exception for progressive disclosure applies and yields a 5.

Specificity

The description ("This is a multiline description. It spans multiple lines. And should be normalized.") names no domain and no concrete actions — it is pure placeholder/abstract language with no capability described, matching the score-1 anchor.

Completeness

It answers neither 'what does this do' (beyond placeholder self-reference) nor 'when should Claude use it' — there is no 'Use when...' clause and both what and when are extremely vague, matching the score-1 anchor.

Trigger Term Quality

There are no natural keywords a user would say to invoke this skill; the text is generic test scaffolding with no real trigger terms, matching the score-1 anchor.

Distinctiveness Conflict Risk

The description is entirely generic placeholder text with no distinguishing niche, so it would conflict with virtually any skill, matching the score-1 anchor.
