Quality

Content

92%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a lean, actionable, well-structured analysis checklist with a clear output format and error-handling table. Its main weakness is a dangling inline reference to quality-gates.md that has no corresponding bundle file.

Suggestions

Add the missing references/quality-gates.md file (with the page-type word-count minimums) or remove the inline '(see quality-gates.md)' reference so no path is unresolved.

Move time-sensitive guidance such as 'FAQ for rich results (retired May 2026)' and the HowTo deprecation note into a labeled 'Deprecated / old patterns' section to keep the core checklist evergreen.

Make the analysis-to-output sequence explicit (e.g., a short numbered '1. Fetch and parse HTML, 2. Run each checklist section, 3. Produce the score card, 4. List issues by priority') so the workflow order is unambiguous.

DimensionReasoningScore

Conciseness

Lean bullet checklists with concrete thresholds ('Title tag: 50-60 characters', '>200KB (warning), >500KB (critical)') assume Claude's competence and avoid explaining basic SEO concepts. The inline 'retired May 2026' date earns its place as actionable deprecation guidance though it is not in a labeled deprecation section.

3 / 3

Actionability

Concrete numeric thresholds, an explicit output score-card template with priority ordering, and ready-to-use JSON-LD suggestion guidance make the direction executable for an instruction-only analysis skill.

3 / 3

Workflow Clarity

A clear deliverable sequence (Score Card -> Issues by priority -> Recommendations -> Schema Suggestions) plus an error-handling decision table with per-scenario actions gives a well-defined single-pass workflow appropriate for analysis (no destructive/batch validation cap applies).

3 / 3

Progressive Disclosure

Sections are well-organized, but the inline reference '(see quality-gates.md)' points to a file that does not exist in references/ (all bundle directories are empty), leaving an unresolved, dangling reference.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, concise description that states concrete capabilities and provides explicit, natural trigger phrases covering what the skill does and when to use it. It is distinctive and uses proper third-person voice.

DimensionReasoningScore

Specificity

Lists multiple concrete capability areas ('on-page elements, content quality, technical meta tags, schema, images, and performance') rather than vague language.

3 / 3

Completeness

Explicitly answers both what ('Deep single-page SEO analysis covering...') and when ('Use when user says...') with explicit trigger guidance.

3 / 3

Trigger Term Quality

Natural phrases a user would actually say ('analyze this page', 'check page SEO', 'single URL', 'page analysis') give good coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Clear single-page-SEO niche with distinct triggers, unlikely to fire for unrelated skills; voice is correctly third person.
