Conciseness

The body is dense and imperative — tabular detection logic ("yarn.lock → use yarn add", dependency checks), library-specific facts Claude would not know ("React's DataProvider has a backup <Suspense>, so a Suspense boundary above it never catches"), and no basic-concept explanations. Not 5 because of minor trims available: the NextJS import path ("@data-client/react/nextjs") is stated three times (inline note, checklist, Common Issues), and some detection pattern lists ("query {, mutation {, subscription {") restate what Claude already knows; not 3 because padding is minor relative to the skill's justified complexity.

Actionability

Guidance is fully executable throughout: per-package-manager install commands ("npm install @data-client/react && npm install -D @data-client/test"), the skills-linking command ("npx --no data-client-skills"), a verbatim AGENTS.md snippet, and complete copy-paste provider code for all five framework variants. Specific examples cover the common cases, matching the top anchor.

Workflow Clarity

A clear sequence runs from numbered detection steps (1-5) through skill/package installation, provider setup, and protocol-specific guides, ending in an explicit "Verification Checklist" with per-phase checkboxes. Feedback loops for error recovery are present ("If it reports Kept .agents/skills/data-client-setup... Remove it... and run the command again"; "If the command isn't found... install the skills with the skills CLI"; the TanStack "Check the migration" list), matching the top anchor.

Progressive Disclosure

The SKILL.md is a genuine overview: protocol detail is delegated to real bundled one-level-deep guides (references/data-client-rest-setup.md, data-client-graphql-setup.md, data-client-endpoint-setup.md, tanstack-query-migration.md — all verified to exist), API docs live in an annotated References list with one-line descriptions, and the Vue convention ("read <name>.vue.md instead of <name>.md when it exists") matches actual .vue.md files on disk. Content split and navigation match the top anchor; not 4 because no organization gaps were found.

Specificity

"Install and set up @data-client/react or @data-client/vue", "Detects project type (NextJS, Expo, React Native, Vue, plain React) and protocol (REST, GraphQL, custom)", and "follows the bundled protocol-specific setup guide" name several concrete, specific actions. Not 5 because coverage has a minor gap: the skill also handles TanStack Query replacement, which the description omits; not 3 because far more than 1-2 actions are enumerated.

Completeness

The "what" is clearly and concretely answered (install/set up these packages, detect project type and protocol, follow the bundled guide), but there is no "Use when..." clause or equivalent explicit trigger guidance — "in a project" only weakly implies when, which caps completeness at 3 per the judging guidelines. Not 4 because no explicit or specific 'when' is present at all.

Trigger Term Quality

Natural terms users would say are present: "Install", "set up", framework names ("NextJS, Expo, React Native, Vue"), and protocol names ("REST, GraphQL"). Not 5 because common synonyms and phrasings are missing — the bare product name "Data Client", "add"/"integrate", and migration triggers like "migrate from TanStack Query" or "react-query"; not 3 because coverage goes well beyond a couple of generic keywords.

Distinctiveness Conflict Risk

Exact package names "@data-client/react or @data-client/vue" establish a clear setup/install niche, and the enumerated project types and protocols further distinguish it. Conflict risk is minimal — a request containing these package names or "set up Data Client" could not plausibly route to another skill; not 4 because no meaningful overlap risk with closely related skills is created by this description.
