Conciseness

The body is lean: rules delivered via tables, an executable grep check, and no explanation of concepts Claude already knows (no CSS-variable tutorials, no library comparisons). Not 5 because the 22-line tokens.css example mostly demonstrates a naming convention Claude could infer from a 5-line sample, and the 'Convoy Integration' fenced block restates its five items in prose; not 3 because there is no padded or over-explained section.

Actionability

Concrete, usable guidance throughout: exact paths ('src/styles/tokens.css', 'src/components/Layout.tsx'), an executable check ('grep -rF "style={{" src/pages/'), naming rules (PascalCase components, camelCase props), and a copy-paste-ready tokens.css with the var-only usage pattern 'bg-[var(--color-primary)]'. Not 5 because the foundation checkpoint's 'Layout renders, UI components compile' gives no command or procedure to actually verify those, and the convoy section defers its substance to a file that isn't there.

Workflow Clarity

The two-phase sequence is explicit — 'Phase 1 (sequential): foundation-setup creates tokens, Layout, UI library, style guide brief. Phase 2 (parallel): every page task imports from Phase 1' — with two numbered validation checkpoints including a zero-hit grep gate. Not 5 because there is no error-recovery feedback loop telling an agent what to do when the per-page grep returns hits or imports fail to resolve; not 3 because checkpoints are explicit and concrete, not merely implied.

Progressive Disclosure

Sections are well-organized, but the body's only external reference — 'Prompt templates: see [TEMPLATES.md](./TEMPLATES.md)' — points to a file that does not exist anywhere in the skill directory, and no references/, scripts/, or assets/ bundle is present. Navigation to the prompt templates (the operational core of the Convoy Integration section) is a dead end, matching the anchor where referenced content is effectively unreachable. Not 3 because a clearly signaled-but-missing reference is worse than one that is merely 'not clearly signaled'; not 1 because the in-body content is genuinely sectioned and self-navigable.

Specificity

Names the domain and three concrete actions — 'Generates shared CSS variables, validates component naming conventions, creates layout pattern templates' — each with a specific object and verb. Not 5 because coverage stops at three actions with no mention of related capabilities (e.g., validation tooling, drift checks); not 3 because the actions listed are specific and complete as stated rather than minimal.

Completeness

Explicitly answers 'what' (three concrete generative/validating actions) and 'when' with a concrete 'Use when coordinating design system, theme, consistent styling, CSS variables, or component library across parallel agents' clause listing multiple trigger phrases. Voice is third person throughout. Matches the anchor-5 pattern of concrete actions plus an explicit multi-trigger 'Use when' sentence.

Trigger Term Quality

The 'when' clause covers natural user phrasings: 'design system', 'theme', 'consistent styling', 'CSS variables', 'component library'. Not 5 because common variations like 'design tokens', 'shared styles', 'styling consistency', or 'shared components' are missing; not 3 because several natural, likely-spoken terms are present rather than just a few relevant keywords.

Distinctiveness Conflict Risk

CSS variables, design tokens, and the 'across parallel agents' framing carve a fairly distinct niche with specific triggers. Not 5 because broad terms like 'theme' and 'consistent styling' could also fire on generic styling or theming requests where this orchestration skill is not wanted; not 3 because the parallel-agent coordination context meaningfully separates it from ordinary styling skills.
