Conciseness

Mostly dense and information-bearing (class tables, a full component, checklists), but the LCP/CLS targets are repeated in the header line, the SEO Checklist, and the Performance Targets table, and "Common Pitfalls" restates checklist items (image preload, mobile CTA). Not score 5 because of this repetition; not score 3 because there is no padded explanation of concepts Claude already knows.

Actionability

The hero component is copy-paste-ready TSX and the design-style table gives exact Tailwind classes, but the non-hero sections (features, pricing, FAQ, testimonials) are prose pattern descriptions rather than code, and the bundled scaffolder script (scripts/landing_page_scaffolder.py) is never mentioned as a concrete tool. Not score 5 because coverage of the common cases is incomplete in code form; not score 3 because the guidance given is specific and executable in structure.

Workflow Clarity

The 7-step generation workflow is clearly sequenced with an explicit validation checkpoint ("run through every item in the SEO Checklist... Fix any gaps inline — do not skip items"), which is a real fix-and-continue loop. Not score 5 because step 2 depends on an external path (marketing-skill/skills/content-production/scripts/brand_voice_analyzer.py) not present in this bundle, there is no re-validation after fixes, and the stated performance targets have no verification step.

Progressive Disclosure

The bundle ships four reference files (conversion-patterns.md, copy-frameworks.md, landing-page-patterns.md, seo-checklist.md) and a scaffolder script, but the body never links to any of them — instead it inlines its own SEO Checklist, Copy Frameworks, and section-pattern sections that duplicate that reference material. This matches score 2 ("content that clearly belongs in separate files is inlined; or references are buried"); not score 3 because the local references are not merely unclearly signaled, they are entirely unreferenced.

Specificity

Lists multiple specific concrete actions in third person — "Creates hero sections, feature grids, pricing tables, FAQ accordions, testimonial blocks, and CTA sections", "Outputs SEO meta tags, structured data, and performance-optimised code targeting Core Web Vitals (LCP under 1s, CLS under 0.1)" — with comprehensive coverage of the skill's output surface. Not score 4 because coverage extends beyond section types to copy frameworks, structured data, and quantified performance targets.

Completeness

Explicitly answers both what ("Generates high-converting landing pages as complete Next.js/React (TSX) components with Tailwind CSS") and when ("Use when the user asks to create a landing page...") with concrete trigger phrases. Matches the score-5 anchor structure exactly; not score 4 because the when-clause is already fully explicit.

Trigger Term Quality

Comprehensive natural trigger terms with synonyms: "landing page, marketing page, homepage, single-page site, lead capture page, campaign page, promo page, or conversion-optimised web page", plus A/B testing variants and "replace a static page with one designed to convert". These are phrases a user would naturally say; not score 4 because no common variation is missing.

Distinctiveness Conflict Risk

Clear niche (conversion-focused landing/marketing pages in Next.js/Tailwind) with distinct trigger phrases; minimal conflict risk with adjacent web-development skills. Terms like "homepage" broaden it slightly, but the conversion-optimisation framing keeps the niche distinct — fits the score-5 anchor better than score 4's "minor overlap risk".
