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.

A well-structured, actionable skill body with a concrete extraction command, explicit success criteria, error-handling feedback loops, and clean one-level-deep reference to its script bundle. Minor conciseness gains are available in the inline output-spec comments.

DimensionReasoningScore

Conciseness

Mostly lean and assumes Claude's competence; avoids explaining basic concepts. The large JSON output example carries per-field inline comments that earn their place but could be trimmed slightly for some obvious fields.

4 / 5

Actionability

Copy-paste-ready executable command ('eval "$(python scripts/extract-item-detail.py)"'), explicit preconditions (navigate -> wait stable), a full output example, and concrete per-error root-cause/remediation guidance.

5 / 5

Workflow Clarity

Clear sequence (navigate -> wait stable -> eval) with explicit validation via the Success Criteria section and a test-before-batch checkpoint plus error-resumption feedback loop. Falls just short of the top anchor because the main extraction flow is not presented as an explicit numbered validated checklist.

4 / 5

Progressive Disclosure

Well-organized single overview with a one-level-deep, clearly signaled reference to scripts/extract-item-detail.py ('no need to read scripts/*.py source code... Only inspect scripts when execution fails'). The bundle file referenced in the body exists, and extraction logic is appropriately split into the script.

Description

95%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.

A strong, highly specific description with comprehensive trigger-term coverage and a clear what/when structure. The main action is a single extraction task, which keeps specificity just short of the top anchor despite broad field and use-case enumeration.

DimensionReasoningScore

Specificity

Names the concrete action ('Extracts full item detail from any open eBay item URL') and enumerates 25+ output fields plus several use cases (monitoring, research, audits), but the actions are largely variations of one extraction task rather than multiple distinct operations.

4 / 5

Completeness

Explicitly answers both 'what' (extracts full item detail returning JSON with named fields) and 'when' ('Use when user mentions eBay item page...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural-term coverage including synonyms and path tokens users actually say: 'eBay item page', 'eBay itm', 'ebay.com/itm', 'scrape eBay item', 'eBay sold count', 'eBay hi-res images', 'eBay brand MPN UPC EAN'.

5 / 5

Distinctiveness Conflict Risk

Clear niche (eBay item-detail extraction with /itm/{digits} URLs) and distinct, eBay-specific triggers that are unlikely to fire for unrelated skills.
