Conciseness

The body is lean (~45 lines) with purposeful sections and no padding explaining concepts Claude already knows; the Quick Reference bullets deliver rule-specific facts (e.g., 'the schema is a signal, not a guarantee'). Not level 5 because the intro sentence about 'reducing friction for brand-aware users' is trimmable rationale and the 'query-input' format is repeated between Quick Reference and Fix; not level 3 because there is no noticeably unnecessary explanation.

Actionability

The Fix section gives concrete, field-level instruction — 'Set potentialAction with SearchAction, target pointing to your search results URL with {search_term_string} placeholder, and query-input as required name=search_term_string' — enough to construct the markup without the reference. Not level 5 because there is no inline copy-paste JSON-LD example in the body (it is delegated to references/rule.md); not level 3 because the guidance names exact properties and values rather than being pseudocode or missing key details.

Workflow Clarity

A clear Check-then-Fix sequence: Check specifies exactly what to verify ('a <script type=application/ld+json> block with "@type": "WebSite" and a potentialAction of type SearchAction', 'Verify target is a valid search URL template'), and Fix follows with the remedy. Not level 5 because there is no explicit re-validation loop after applying the fix (the Check step is not repeated post-Fix); not level 3 because the verification checkpoint is explicit and the sequence is unambiguous for this simple skill.

Progressive Disclosure

The body is a concise overview with well-organized sections and a single, clearly signaled, one-level-deep reference — 'For full implementation details, code examples, and framework-specific guidance, see references/rule.md' — and that file exists in the bundle. Content is appropriately split (implementation detail out, summary in), matching the top anchor for this short skill.

Specificity

The description names the domain ("internal site search functionality", "branded search result appearance", "adding structured data") and implies 1-2 concrete actions, matching the anchor for naming a domain with limited actions. It is not level 4 because no distinct capability statement lists several actions, and not level 2 because the actions referenced (adding structured data, optimizing branded search appearance) are specific rather than generic — though the garbled opening clause 'Use when applies to sites' weakens clarity.

Completeness

Both clauses are 'Use when' triggers; the description never states what the skill does (e.g., 'Adds WebSite SearchAction JSON-LD schema...'). This matches the anchor-2 pattern 'only when is present without what' (example: 'Use when working with documents'). Per the guideline to score only what is explicitly stated, the what cannot be inferred, so it cannot reach level 3-4 despite the strong explicit when-clauses.

Trigger Term Quality

Good keyword coverage: 'internal site search functionality', 'branded search result appearance', 'structured data' are natural phrases a user might say. Not level 5 because common synonyms users would actually use — 'sitelinks searchbox', 'WebSite schema', 'JSON-LD', 'search box in Google results' — are absent; not level 3 because the present terms are varied and reasonably natural rather than only technical jargon.

Distinctiveness Conflict Risk

The triggers are fairly niche (site search functionality, branded search result appearance, structured data for the first time), giving mostly distinct activation. Not level 5 because 'structured data' and 'adding structured data for the first time' overlap with sibling SEO/structured-data skills; not level 3 because the site-search and branded-result qualifiers keep overlap minor.
