Conciseness

Lean and assumes Claude's competence (no basic explanations of Astro/CMS/Portable Text), but the final 'Reference Documents' table duplicates paths already linked in the Workflow steps, a minor redundancy.

Actionability

Provides copy-paste-ready TypeScript imports and query calls in the cheat sheet, exact gotcha fixes (e.g. '<Image image={post.data.featured_image} />', 'getTerm("category", slug)'), and concrete commands like 'pnpm dev'.

Workflow Clarity

A clear six-step sequence (Configure, Design schema, Build pages, Wire up features, Create seed, Run and verify) is present, but the 'Run and verify' step lacks explicit validation checkpoints or feedback loops.

Progressive Disclosure

A concise overview points to four real one-level-deep reference files (configuration.md, schema-and-seed.md, querying-and-rendering.md, site-features.md), each clearly signaled with bold links and summarized in a navigation table.

Specificity

Lists multiple concrete actions -- 'schema and seeds, content queries, Portable Text rendering, menus, taxonomies, widgets, and deployment configuration' -- giving comprehensive coverage of the skill's capabilities.

Completeness

Explicitly answers both what ('Build the site-facing parts...') and when ('Use for EmDash site and theme work; use creating-plugins instead when the task is plugin authoring alone.') with concrete trigger phrases.

Trigger Term Quality

Good keyword coverage with natural terms ('EmDash site and theme work', 'plugin authoring', 'Astro'), but lacks synonyms or file extensions that would push it to comprehensive.

Distinctiveness Conflict Risk

Clear niche (EmDash CMS on Astro) with an explicit boundary clause directing plugin work to a separate skill, minimizing conflict risk.
