Conciseness

Core checklists are dense and skill-specific (word-count floors table, E-E-A-T weight split 30/25/25/20, error-handling actions), but generic SEO knowledge Claude already has is restated ("Relevant images with proper alt text", "Secure site (HTTPS)", "Sentence length: average 15-20 words", "Open in new tab"), and heavy time-sensitive date annotations are inlined rather than in a deprecated/old-patterns section ("March 2024 core update", "QRG ... September 11, 2025", "published 2026-05-15, last updated 2026-07-10", "Gemini 3.5 Flash became the default on 2026-05-19"), with the Gen-AI-is-SEO point stated twice (AI Content Assessment blockquote and the GEO section). This is more padding than the level-4 anchor allows but the majority of sections are still efficient, so it sits at 3 rather than 2.

Actionability

Concrete, executable guidance dominates: copy-paste-ready commands ("\"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo\" run content_humanize.py draft.md -o cleaned.md", "seo_updates.py --since <yyyy-mm> --json"), a specific output template with per-factor score bands (Experience XX/20 ... Trustworthiness XX/30), page-type minimum table, named MCP tools ("kw_data_google_ads_search_volume", "content_analysis_summary"), and a per-scenario error-action table. Not level 5 because the page-fetch/analysis mechanics are left implicit and some criteria sections remain descriptive checklists rather than fully specified instructions.

Workflow Clarity

An audit sequence is implied by section order and the Output template (Who/How/Why test first, then E-E-A-T scoring, then metrics, then cleanup), and the Error Handling table gives explicit contingencies for unreachable, paywalled, and thin-content pages. But no explicitly numbered or ordered steps exist, checkpoints are implicit (e.g., no instruction to confirm successful fetch before scoring E-E-A-T), and the update-correlation workflow's hypothesis-check is a caveat rather than a validation loop — matching the level-3 anchor of 'sequence present but checkpoints missing or implicit' rather than level 4's 'most checkpoints present'.

Progressive Disclosure

References are clearly signaled and one level deep ("Read .../references/eeat-framework.md for full criteria and .../eeat-scoring-guide.md for score bands", cross-referencing the seo-geo skill's google-ai-optimization-guide.md), and sections are well-organized with a coherent overview-plus-details split. Below level 5 because the inlined E-E-A-T sub-bullets and metrics checklists partially duplicate the referenced detail files, GEO guidance appears in two separate sections, and no bundle files (references/, scripts/) exist alongside this SKILL.md to verify the referenced paths resolve.

Specificity

Quotes: "Evaluate page content for usefulness, E-E-A-T, readability, thinness, and AI citation readiness, plus last-mile draft cleanup (AI-typical phrasing and invisible Unicode watermark characters)" lists several specific evaluation capabilities plus a concrete cleanup task. It falls short of the level-5 anchor because capabilities like word-count/thin-content analysis detail, freshness review, and update-correlation are only partially covered, and the verbs ("evaluate", "analyze") are less concrete than level-5 examples like "extract text and tables, fill forms, merge documents".

Completeness

The 'what' is explicit and multi-part ("Evaluate page content for usefulness, E-E-A-T, readability, thinness, and AI citation readiness, plus last-mile draft cleanup"), and an explicit 'when' clause exists ("Use for content-only analysis, not full-page technical checks"). It is not level 5 because the 'when' is a scoping boundary rather than concrete trigger phrases like "Use when the user asks to audit a page's content quality or humanize a draft".

Trigger Term Quality

Quotes: "E-E-A-T, readability, thinness, and AI citation readiness" are natural terms an SEO practitioner would say when requesting this skill, and "page content" / "content-only analysis" match common phrasing. Not level 5 because frequently used synonyms such as "content quality", "thin content", "SEO audit", or "humanize this draft" are absent.

Distinctiveness Conflict Risk

Quotes: "Use for content-only analysis, not full-page technical checks" explicitly scopes it away from technical-SEO skills, and the focus on E-E-A-T/content evaluation is a clear niche. Minor overlap risk remains with closely related skills (e.g., a GEO/AI-citation or general SEO audit skill covering some of the same signals), keeping it below the level-5 anchor.
