Conciseness

Extremely lean — no explanations of concepts Claude already knows, and the telegraphic style assumes competence ("a write replaces the whole file: a copy read earlier would undo a rename"). Falls short of 5 because critical rules are repeated in several places (the index "written LAST" appears in the table, in Creating step 3, and in Revising step 3) and version-sensitive detail (React 18/19, Node 20+) sits inline rather than in a consolidated spot; still well above 3 since there is no padding or filler.

Actionability

Largely executable: exact CLI invocations ("upload <root> <file> --group <Group>", "check <root>" → "problems"), complete JSON examples for the index and tokens.json, a verbatim npm-install line, and a full copy-paste pre-commit hook script. Not 5 because a few steps are described rather than given as commands — the React 19 bundling route says only "(esbuild, format iife, production)" with no verbatim esbuild command — but it is far from the 3 anchor's pseudocode level.

Workflow Clarity

Both multi-step workflows are numbered and end in an explicit validation loop: "run `check` and fix what it names until `problems` is 0" (Creating step 3) and "Then `check` until `problems` is 0" (Revising step 3). Risky operations carry safety gates — "Never delete uploads unprompted" and "A path read from the index or a README holding `..`, `\` or a leading `/` never names a file: stop and say so" — plus ordering rules (uploads first, index last).

Progressive Disclosure

References are clearly signaled and one level deep with stated purpose ("format.md ... read before writing components", "craft.md", "cover.md", "from-design-tool.md", "from-code.md", "artifact-type/demo.json is a WORKED EXAMPLE"), but none of these files exist in the bundle as shipped — there is no `artifact-type/reference/` directory, only `scripts/artifact.mjs`, `scripts/server.mjs`, and `scripts/editor/`. Scoring against the actual bundle structure, the disclosure path a reader is told to follow (e.g., the full token grammar lives only in the missing format.md) is broken, which is more than the 4 anchor's 'minor organization gaps' though better than the unstructured 2 anchor.

Specificity

Multiple concrete actions with concrete artifacts: "Create and revise design systems in the Design System artifact format (project/design-system.json, tokens.json, a README brand book, component previews, fonts and asset groups)" then "open them in a local design-system page where the user can browse and edit tokens, type, components and assets". Coverage spans creation, revision, and the browsing/edit surface, so it is not the 4 anchor ('minor gaps in coverage').

Completeness

Both halves are explicit: the 'what' ("Create and revise design systems ... as local files, then open them in a local design-system page") and the 'when' ("Use when the user asks for a design system or brand kit in this format ... or wants to revise a folder that holds project/design-system.json"). This matches the anchor-5 pattern of concrete trigger phrases attached to an explicit 'Use when' clause, not the 4 anchor where the 'when' could be more specific.

Trigger Term Quality

Natural terms and their synonyms are covered: "a design system or brand kit", "built from a code repository, a design tool or scratch", "names claude-design-system or the Design System type", "revise a folder that holds project/design-system.json". It even adds negative triggers ("Not for a free-form HTML style guide, UI kit or token page"), going beyond the 4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

Clear niche (the Design System artifact format, claude-design-system) with explicit fencing against the nearest neighbors: "Not for a free-form HTML style guide, UI kit or token page". It also states its relationship to adjacent skills ("claude-slides and claude-design install these systems"), keeping conflict risk minimal rather than merely 'minor overlap'.
