Discovery

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.

This is a strong skill description that clearly defines its scope around technical SEO with specific, concrete actions and an explicit 'Use when' clause with excellent trigger terms. It uses proper third-person voice and covers both common and specific SEO terminology that users would naturally use. The description is concise yet comprehensive, making it easy to distinguish from related skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: meta tags, JSON-LD structured data, sitemaps, crawlability fixes, schema markup, robots.txt updates, canonical URLs, and Open Graph tags.

3 / 3

Completeness

Clearly answers both 'what' (implements technical SEO: meta tags, JSON-LD structured data, sitemaps, crawlability fixes) and 'when' (explicit 'Use when...' clause listing specific trigger scenarios like adding schema markup, robots.txt updates, canonical URLs, etc.).

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'meta tags', 'JSON-LD', 'structured data', 'sitemaps', 'schema markup', 'robots.txt', 'canonical URLs', 'Open Graph tags', 'crawlability', and 'SEO' are all terms users naturally use when requesting these tasks.

3 / 3

Distinctiveness Conflict Risk

Clearly scoped to technical SEO specifically, with distinct triggers like JSON-LD, robots.txt, canonical URLs, and Open Graph tags that are unlikely to conflict with other skills such as general web development or content writing.

Implementation

100%

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

This is a well-crafted skill that balances conciseness with completeness. It provides executable code examples, clear multi-step workflows with validation checkpoints, and appropriately delegates detailed reference material to a separate file. The checklists with specific measurable criteria (character counts, image dimensions, load times) make the guidance highly actionable.

DimensionReasoningScore

Conciseness

The content is lean and efficient. It doesn't explain what SEO is or what meta tags do—it assumes Claude knows these concepts and jumps straight to actionable patterns. Every section earns its place with concrete code, checklists, or workflow steps.

3 / 3

Actionability

Provides fully executable TSX code for meta tags/Open Graph, a concrete robots.txt example, and specific checklists with measurable criteria (character counts, image dimensions, load time thresholds). The guidance is copy-paste ready and specific.

3 / 3

Workflow Clarity

The implementation workflow is clearly sequenced with explicit checkpoints after each step (unique title check, Rich Results Test validation, sitemap accessibility, robots.txt verification) and includes a recovery action for accidental Disallow entries. The post-deploy monitoring step closes the feedback loop.

3 / 3

Progressive Disclosure

The SKILL.md provides a clear overview with essential code examples inline, then appropriately delegates detailed structured data examples, validation commands, and anti-patterns to REFERENCE.md with well-signaled one-level-deep references.
