Quality

Content

72%

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

A well-structured, actionable skill body with concrete config/code examples and a clean one-level reference to rule.md. It loses points for a redundant QDF explanation and the absence of an explicit post-fix validation feedback loop.

Suggestions

Collapse the opening QDF paragraph and the Explain section into one concise statement to remove the duplicated explanation.

Add an explicit verification step after Fix (e.g., re-run the Check items or curl the Last-Modified header) to form a validate→fix→retry loop.

Replace the vague Apache bullet ("ensure mod_headers is enabled") with a concrete directive so every server example is equally actionable.

DimensionReasoningScore

Conciseness

The body is mostly lean, but the QDF concept is explained twice — once in the opening paragraph ("Google's Query Deserves Freshness (QDF) algorithm boosts recent or recently updated content") and again in the Explain section — adding redundancy Claude does not need.

2 / 3

Actionability

Concrete, copy-paste-ready guidance is provided: Nginx `add_header Last-Modified $date_gmt;`, an Article JSON-LD `dateModified` example, and a Next.js/MDX frontmatter wiring example.

3 / 3

Workflow Clarity

Check and Fix are clearly numbered sequences, but there is no explicit validate-then-retry feedback loop; the Code Review section is an inspection checklist rather than a runtime verification step after changes.

2 / 3

Progressive Disclosure

The body is organized into clear sections (Quick Reference, Check, Fix, Explain, Code Review) and points one level deep to a verified `references/rule.md` for full implementation details.

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 description: concrete actions, natural trigger terms, an explicit Use-when clause, and a clearly distinct SEO-freshness niche. No first/second-person voice that would warrant a penalty.

DimensionReasoningScore

Specificity

"auditing content pages for freshness signals, setting up HTTP Last-Modified headers in a web server config, or ensuring Article JSON-LD dateModified is updated when CMS content changes" lists three distinct, concrete actions rather than vague language.

3 / 3

Completeness

It opens with an explicit "Use when" trigger clause and states both what the skill does and the situations that call for it, satisfying the what-and-when requirement.

3 / 3

Trigger Term Quality

Natural terms an SEO practitioner would say are well covered: "freshness signals", "Last-Modified headers", "web server config", "Article JSON-LD dateModified", and "CMS content changes".

3 / 3

Distinctiveness Conflict Risk

The freshness/QDF SEO niche with JSON-LD dateModified and Last-Modified header triggers is clearly scoped and unlikely to fire for unrelated skills.
