Conciseness

The Key Concepts table and code patterns are lean and trust Claude's competence, but roughly a third of the body is the 'Recent Updates (v2.6.0-v2.10.5)' changelog plus a 'Current version: v2.10.5 (September 2026)' line — time-sensitive version and date information that is not placed in an old-patterns/deprecated section and competes for context. Not 4 because this block is a substantial, removable chunk rather than minor trimming.

Actionability

Provides copy-paste-ready executable code: the complete controlled Dialog SFC, the Nuxt module config, and the unplugin-vue-components resolver config, plus uncontrolled Select and asChild patterns. Not 5 because there is no plain package-install command (only auto-import setups) and the Select/asChild snippets omit their imports — minor gaps.

Workflow Clarity

As a reference/lookup skill with no risky operations, its single action is well sequenced: When to Use → Available Guidance table → a conditional Loading Files checklist. Not 5 because the final lookup step is ambiguous — the body advertises 'components/*.md (dialog.md, select.md, etc.)' without saying where they live or that they must be generated, so the flow breaks at the last step.

Progressive Disclosure

Top-level structure is good — a clearly signaled references/components.md with a conditional loading checklist and 'DO NOT load all files at once' — but scored against the actual bundle, the chain is two levels deep and terminates in missing files: no components/ directory exists, so the 'components/*.md' row in the body and all ~50 'components/<name>.md' paths listed in components.md are dangling. Broken navigation at the detail level is more than a minor organization gap, though the signaling itself is clear, which keeps it above 2.

Specificity

The description names the domain ("headless Vue components") and lists several concrete capability areas — "component API, accessibility patterns, composition (asChild), controlled/uncontrolled state, virtualization, and styling integration". It stays at 4 rather than 5 because these are capability topics stated as nouns rather than the concrete actions the top anchor expects, with minor gaps in coverage.

Completeness

Explicitly answers both: what ("provides component API, accessibility patterns, composition (asChild), controlled/uncontrolled state, virtualization, and styling integration") and when ("Use when building with Reka UI"). Not 5 because the when-clause names only a single trigger phrase rather than concrete trigger variations (e.g. mentions of Radix Vue, shadcn-vue, or headless Vue).

Trigger Term Quality

Includes the key natural terms users would say: "Reka UI", "headless Vue components", "asChild", and the crucial alias "Formerly Radix Vue". Not 5 because common variations like "unstyled", "shadcn-vue", "Nuxt UI", and "accessible Vue components" are absent.

Distinctiveness Conflict Risk

A clearly named niche library with distinct triggers — "Reka UI", "Formerly Radix Vue", "headless Vue components" — and the body further defers generic Vue patterns to the vue skill, so conflict risk is minimal.
