Quality

Content

100%

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

A tight, well-organized instruction skill: actionable field lists, explicit validation, and a correctly-signaled one-level reference to a real bundle file. No meaningful conciseness or disclosure issues.

DimensionReasoningScore

Conciseness

The body is lean and well-sectioned (Quick Reference, Check, Fix, Explain, Code Review) with no padding or explanation of concepts Claude already knows. Every section earns its place, matching the level-3 'lean and efficient' anchor.

3 / 3

Actionability

It gives concrete, specific guidance — exact required fields (name, image, description, offers.price, offers.priceCurrency, offers.availability), ISO 4217 / schema.org URL constraints, reviewCount > 0 check, and validation via Google's Rich Results Test. Per the code-vs-instruction note, the absence of a code block is not penalized because the instruction guidance is highly actionable.

3 / 3

Workflow Clarity

Check→Fix→Code Review is sequenced with explicit validation steps ('Validate with Google's Rich Results Test', 'Run through Google's Rich Results Test'). For a simple single-task SEO skill, the validation checkpoints satisfy the level-3 simple-skill allowance.

3 / 3

Progressive Disclosure

SKILL.md is a concise overview with a single clearly-signaled one-level-deep reference ('see references/rule.md'), and that bundle file exists in ./references/. Organization is clean and navigation is easy, matching the level-3 anchor.

Description

90%

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 with an explicit 'Use when' trigger and a clear e-commerce/structured-data niche. Specificity could go further by naming concrete schema actions (adding/validating Product JSON-LD) rather than the broader verbs it uses.

Suggestions

Add a concrete action verb tied to the skill's output, e.g. 'Add and validate Product JSON-LD schema on e-commerce product pages'.

Include a natural trigger term a user might say, such as 'product schema' or 'rich results', to broaden keyword coverage.

DimensionReasoningScore

Specificity

Quotes 'auditing e-commerce product pages' and 'implementing structured data for a shop' name the domain and concrete actions, but the action set is not comprehensive (no mention of rich-result validation or specific schema fields). It is above the vague anchor (1) but short of the multi-specific-action example (3).

2 / 3

Completeness

It explicitly states what it does ('auditing e-commerce product pages or implementing structured data for a shop') and when to use it ('Use when ... Applies to any page selling or describing a specific product'). Both what and when are explicit, matching the level-3 example.

3 / 3

Trigger Term Quality

'e-commerce product pages', 'structured data', 'shop', and 'selling or describing a specific product' are natural terms a user would say. It is above level 2 (which would miss common variations) because it captures several phrasings users actually use.

3 / 3

Distinctiveness Conflict Risk

The niche (e-commerce product pages / shop structured data) is clear and distinct, with triggers unlikely to fire for unrelated skills. It is well above the generic/conflict-prone anchor (1).
