Conciseness

The body is mostly lean, but the opening sentence is repeated verbatim in the 'Explain' section ('Google's Search Quality Rater Guidelines and Helpful Content system reward pages...'), the E-E-A-T acronym expansion is a concept Claude already knows, and 'Code Review' substantially overlaps 'Check'. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') — the redundancies are real but bounded, not pervasive enough for anchor 2.

Actionability

As an instruction-only skill, the guidance is concrete: 'Check' poses specific evaluation questions (first-hand experience, search intent, accuracy, depth), 'Fix' gives a 5-point enumerated remediation list, and 'Code Review' provides a 6-item signal checklist. It fits anchor 4 ('mostly executable guidance... with minor gaps') rather than 5 because some directives remain generic ('add specific details, examples, or data not found on competing pages').

Workflow Clarity

The Check → Fix → Explain → Code Review sections give a recognizable evaluate-then-fix sequence, but there are no validation checkpoints or a re-check loop in the body — the reference file's Verification section is never surfaced. This matches anchor 3 ('steps listed but validation gaps; sequence present but checkpoints missing or implicit') and the skill is multi-step (evaluate then rewrite), so the simple-skill exception does not apply.

Progressive Disclosure

The body is a concise overview and the single bundle file is clearly signaled ('For full implementation details, code examples, and framework-specific guidance, see references/rule.md'), which exists and is exactly one level deep with no nested skill references. This matches anchor 5 ('clear overview with well-signaled one-level-deep references; content appropriately split; easy navigation').

Specificity

The description names the domain ('evaluating content pages for SEO quality') and a single concrete action (evaluating), plus target page types (blog posts, product descriptions, landing pages). It matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive') because it never states what the evaluation covers (e.g., E-E-A-T signals, thin content, authorship); it is above anchor 2 because the enumerated page types go beyond a bare domain mention.

Completeness

Both parts are present: 'what' ('evaluating content pages for SEO quality') and an explicit 'when' ('Use when evaluating... Applies to blog posts, product descriptions, landing pages...'). It fits anchor 4 ('both what and when; when could be more explicit or specific') rather than 5 because the 'what' is a single thin action that doesn't convey the skill's actual capabilities.

Trigger Term Quality

Natural phrases users would say are present: 'SEO quality', 'blog posts', 'product descriptions', 'landing pages', 'organic search traffic'. This matches anchor 4 ('good keyword coverage; a few natural terms missing') — common variations like 'content quality', 'E-E-A-T', 'thin content', or 'SEO audit' are absent, keeping it below anchor 5.

Distinctiveness Conflict Risk

The 'SEO quality' framing plus concrete page-type triggers make it mostly distinct from non-SEO skills, matching anchor 4 ('mostly distinct; minor overlap risk with closely related skills'). It falls short of anchor 5 because 'any page expected to receive organic search traffic' is broad and could overlap with sibling SEO auditing/optimization skills.
