Conciseness

The body is bullet-driven with no explanation of what Figma, Storybook, or atomic design are, and includes a tight two-tier token example ("color-blue-600" base + "color-text-link" semantic). Not a 5: sections like "Why this layer matters" ("Tokens are the source of truth for everything above") and parts of the per-element documentation checklist restate what a competent model already knows and could be trimmed; not a 3: padding is minor, not a pattern.

Actionability

For an instruction-only skill the guidance is fully executable: two ordered workflows (9-step build, 6-step audit) with specific numbers ("The 10 to 15 components that appear most often"), named deliverables ("a markdown report at `design-system-audit.md`" with a 6-part structure), and concrete per-layer output lists. Not a 4: both the build and audit cases are covered end-to-end with copy-paste-ready process guidance and no significant gaps.

Workflow Clarity

Both workflows are clearly sequenced with per-step guidance and explicit prioritization ("Foundation gaps first. High-use component drift second. Rarely-used component cleanup last"), and there is an upfront gate ("If brand identity is undefined, run `brand-identity` first"). Not a 5: no explicit validation/verification steps inside the workflows (e.g., verifying token accessibility or piloting with one team before rollout) — co-design and drift checks appear only in the failure-patterns section; not a 3: the sequences are far richer than a bare step list and contain an entry checkpoint.

Progressive Disclosure

The body is an overview with a dedicated "Reference files" section linking three real, one-level-deep files (`references/system-architecture.md`, `references/system-audit-template.md`, `references/governance-playbook.md`), each with a one-line description; grep confirms no nested references inside the bundle files. Not a 4: navigation is easy, references are clearly signaled, and the split (framework summary inline, detail in references) is appropriate.

Specificity

"Build or audit a design system including component library, design tokens, naming conventions, contribution model, and documentation" plus "define design tokens at the system level, structure a component library, or set up design system governance" lists multiple concrete, comprehensive actions in third person. Not a 4: coverage spans build, audit, token definition, library structure, and governance with no meaningful gaps in the domain.

Completeness

Explicitly answers both what ("Build or audit a design system including component library, design tokens, naming conventions, contribution model, and documentation") and when ("Use this skill whenever the user wants to build a design system, audit an existing system... Triggers on...") with concrete trigger phrases. Not a 4: the 'when' clause is explicit and enumerates specific triggering scenarios, not just a general condition.

Trigger Term Quality

Triggers include "design system, component library, design tokens, atomic design, atoms, molecules, organisms, design system documentation, Storybook, Figma library, system governance, design contribution model" — natural user phrasing plus synonyms and tool names, and a scenario trigger ("teams are inconsistent across products"). Not a 4: no natural term in this domain is obviously missing.

Distinctiveness Conflict Risk

"Design system" at the system level is a clear niche, but "design tokens" and "Storybook" are terms that plausibly also trigger closely related skills (the body itself routes token templates to a sibling `design-standards` skill). Not a 5: the description does not state its boundary against those sibling skills, leaving minor overlap risk; not a 3: the core triggers are unmistakably system-level rather than generic design work.
