Quality

Content

82%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is a strong, actionable reference: executable commands, a complete worked example, and clearly sequenced workflows with lint-gating guidance. Its main weakness is that validation in the authoring workflow is stated as a step rather than an explicit feedback loop, and some reference material stays inline.

Suggestions

Promote the authoring workflow's lint step into an explicit validate -> fix -> re-lint feedback loop (e.g., 'Lint; if errors, fix and re-run; only return once lint passes').

Consider moving the full lint-rule reference and token-type table into a referenced file (e.g., reference/lint-rules.md) and linking from the body to tighten the overview.

Tighten the File anatomy example with a brief inline note that variant keys are siblings (currently duplicated in Pitfalls) to reduce repetition.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence (no "what is a design token" filler); every section earns its place, with only minor spots that could be tightened.

4 / 5

Actionability

Copy-paste-ready npx commands, a complete YAML frontmatter example, a token-type table, and a lint-rule reference give fully executable coverage of the common cases.

5 / 5

Workflow Clarity

Two clearly numbered workflows are present with a lint step and 'fix before returning' guidance; validation is mentioned as a step rather than an explicit validate->fix->retry feedback loop, leaving a minor checkpoint gap.

4 / 5

Progressive Disclosure

A single well-organized SKILL.md with clear section headers and no bundle files; structure is good though some reference material (e.g., the full 9-rule lint set) is inlined rather than split out.

Description

58%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description states a clear, concrete purpose but omits any explicit "use when" trigger guidance, which caps completeness and limits natural trigger-term coverage. It is distinct from sibling skills but would benefit from explicit trigger phrases.

Suggestions

Add an explicit 'Use when ...' clause listing concrete trigger phrases (e.g., 'Use when the user asks for a DESIGN.md file, design tokens, or wants to lint/export a design spec').

Broaden trigger terms with natural synonyms and file extensions users say (e.g., 'design tokens', 'token spec', '.md design file', 'WCAG contrast check').

Mention the CLI's key capabilities (lint, diff, export to Tailwind/DTCG) in the description to lift specificity toward 5.

DimensionReasoningScore

Specificity

"Author/validate/export Google's DESIGN.md token spec files" names three concrete actions on a specific domain; slightly short of comprehensive coverage of the full lifecycle.

4 / 5

Completeness

The "what" is clear (author/validate/export token spec files) but there is no "when"/Use when clause, which per the guidelines caps completeness at 3.

3 / 5

Trigger Term Quality

Contains relevant keywords ("DESIGN.md", "token spec", "design system") but lacks common synonyms and the natural trigger phrases users would actually say.

3 / 5

Distinctiveness Conflict Risk

The DESIGN.md format and its CLI are a specific niche; minor overlap risk with general design-system skills but clearly distinguishable.
