Quality

Content

86%Weight 40%Scale 1-5

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, well-organized reference of concrete SEO constraints with an executable inspection command and explicit pre-ship/post-deploy validation gates. Its only weakness is that sitemap and JSON-LD generation are described instructionally rather than with example code.

Suggestions

Add a minimal executable example for sitemap generation (e.g., a one-liner that emits a sitemap.xml or sitemap index from a data source) to lift actionability toward fully copy-paste-ready.

Include a short example JSON-LD script block template so the 'Structured Data' section shows what to emit, not only how to verify it.

Consider a brief pre-deploy checklist tying the three sections into a single sequenced workflow (implement constraints -> generate JSON-LD -> pass Rich Results Test -> generate sitemap -> deploy -> check Search Console).

DimensionReasoningScore

Conciseness

Lean and efficient with no padding or explanation of concepts Claude already knows; every line is either a concrete constraint or an actionable instruction and every token earns its place.

5 / 5

Actionability

Provides concrete, executable guidance including a copy-paste curl/pup/jq command and specific thresholds (50–60 chars, 1200×630 px, 50,000 URLs/50 MB), but the sitemap and JSON-LD generation steps are described instructionally without example code, leaving minor gaps.

4 / 5

Workflow Clarity

Explicit validation checkpoints are present ('must return 0 errors from Google's Rich Results Test before shipping' and the post-deploy Search Console check with a remediation loop), but the body is organized as parallel topical sections rather than a single sequenced workflow, so it falls just short of the top anchor.

4 / 5

Progressive Disclosure

Under 50 lines with no need for external references and well-organized into clear sections (Constraints, Structured Data, Sitemap & robots.txt), satisfying the simple-skill exception for a top score.

Description

100%Weight 40%Scale 1-5

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

The description is exemplary: it states concrete capabilities and pairs them with an explicit, trigger-rich 'Use when' clause covering synonyms. It answers both what and when with no padding or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — 'meta tags, JSON-LD structured data, sitemaps, crawlability fixes' plus 'schema markup, JSON-LD, robots.txt updates, canonical URLs, Open Graph tags' — giving comprehensive coverage of specific actions rather than vague language.

5 / 5

Completeness

Explicitly answers both 'what' ('Implements technical SEO: ...') and 'when' ('Use when adding schema markup, JSON-LD, robots.txt updates, canonical URLs, Open Graph tags, or improving crawlability.') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes the natural terms users actually say (JSON-LD, schema markup, robots.txt, canonical URLs, Open Graph tags, crawlability) plus synonyms (JSON-LD / structured data / schema markup), matching the comprehensive-coverage anchor.

5 / 5

Distinctiveness Conflict Risk

Targets a clear niche (technical SEO) with distinct, specific triggers (JSON-LD, robots.txt, canonical URLs, OG tags) that are unlikely to fire for unrelated skills, giving minimal conflict risk.
