Conciseness

The body is lean and operational — terse bash snippets, BAD/GOOD tables, and no explanation of concepts Claude already knows. It falls short of the score-5 anchor because of small redundancies: the 'When to Use' list repeats the description's triggers verbatim, and the Mindset section ('developers trust the reference sheet and will use the wrong values') restates the first anti-pattern's WHY. It is well above the score-3 anchor, whose whole-section unnecessary explanations are not present.

Actionability

There is real executable guidance (grep discovery commands, a TBD-gap check, validation invocation), but steps 4–7 depend on artifacts absent from the bundle: 'templates/skill-output.yaml', 'schemas/design-reference.schema.json', and 'bun run generate'/'bun run validate' have no backing files or scripts. This matches the score-3 anchor ('concrete guidance but incomplete ... missing key details') rather than score 4, where gaps would be minor rather than central to half the workflow.

Workflow Clarity

The 8-step sequence is clearly ordered with checkpoints: step 5 gates generation on a gap check ('Gaps found — fill before generating') and step 7 validates against the schema. It falls short of the score-5 anchor because the error-recovery loop is implicit — what to do when the TBD check or validation fails is not spelled out — and the validation command targets a schema file that is missing. It exceeds score 3, where checkpoints would be absent.

Progressive Disclosure

Good structure: the body is an overview pointing to one-level-deep, clearly labelled references, each with a descriptive tag in the References section. Against the actual bundle, however, 2 of the 12 listed paths (templates/skill-output.yaml, schemas/design-reference.schema.json) do not exist, and 2 bundle files (elements-of-design.md, principles-of-design.md) are orphaned — unlisted and undiscoverable. These are minor organization gaps per the score-4 anchor, not the inline-bulk or buried-reference problems of score 3.

Specificity

Multiple concrete actions are listed — 'Extracts CSS custom properties, validates against a JSON schema scratchpad, inspects components, and produces a 12-section document' — with the section topics enumerated (colours, typography, spacing, layout, borders, shadows, motion, accessibility, dark mode, Figma sync notes). This matches the comprehensive-coverage anchor; it is above the score-4 anchor because no concrete capability is missing or generic, and the voice is consistently third person.

Completeness

It explicitly answers both questions: the 'what' ('Generate a project-specific web design reference sheet ... and companion enforcement skill') and the 'when' ('Use when starting a new project, onboarding a design system, ... or auditing existing styles', plus an explicit 'Triggers on:' list of concrete trigger phrases). This is a direct match to the score-5 anchor and above score 4, whose 'when' is present but less explicit.

Trigger Term Quality

Good natural-language coverage: 'create a design reference, generate a style guide, document the design tokens, make a brand reference sheet, port design tokens, audit existing styles'. It falls short of the score-5 anchor, which expects synonyms and file extensions, because terms like '.css', 'CSS variables', or 'design system documentation' are absent; it is clearly above the score-3 anchor because the listed phrases are phrasings a user would naturally say rather than generic keywords.

Distinctiveness Conflict Risk

It occupies a clear niche — generating a project-specific web design reference sheet and enforcement skill — with triggers ('design reference', 'style guide', 'port design tokens', 'audit existing styles') that are unlikely to fire for unrelated skills. It is above the score-4 anchor ('minor overlap risk') because no closely related skill territory is claimed by these triggers.
