Quality

Content

92%

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

A highly actionable, well-sequenced skill body with strong validation checkpoints. Its main weaknesses are mild redundancy in restating source-preference ordering and on-demand references that point to files absent from the bundle.

Suggestions

Consolidate the source-preference ordering into one place (e.g. the Fallback cascade) and have each section reference it, rather than repeating the DataForSEO > Moz > Bing > Common Crawl ordering inline.

Either bundle the referenced `backlink-quality.md` and `free-backlink-sources.md` under ./references/ or correct the paths so the on-demand links resolve within the skill bundle.

Dimension	Reasoning	Score
Conciseness	The body is mostly efficient and free of concept-explanation fluff, but the per-section source-preference ordering is restated a third time in the "Fallback cascade" section, so it could be tightened.	2 / 3
Actionability	Provides copy-paste-ready commands (e.g. `claude-seo run moz_api.py metrics <url> --json`), named DataForSEO tools, and concrete scoring thresholds in tables — fully executable guidance.	3 / 3
Workflow Clarity	The 7-section sequence is clearly ordered with explicit validation checkpoints: the data-sufficiency gate and the MANDATORY pre-delivery review checklist ("If ANY check fails, fix the finding before presenting") provide real feedback loops.	3 / 3
Progressive Disclosure	References are well-signaled and one-level deep ("Load on demand (do NOT load at startup)"), but the referenced files (`skills/seo/references/backlink-quality.md`, `free-backlink-sources.md`) are not present in this skill's bundle, weakening navigation.	2 / 3

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, third-person description that states concrete capabilities and gives a rich explicit trigger clause. It cleanly answers both what the skill does and when to invoke it with minimal risk of skill conflicts.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — "referring domains, anchor text distribution, toxic link detection, competitor gap analysis" — matching the score-3 anchor rather than the single-action score-2 example.	3 / 3
Completeness	Explicitly answers both what (the four analysis capabilities) and when (an explicit "Use when…" trigger), so it is not capped at 2 per the missing-trigger guideline.	3 / 3
Trigger Term Quality	The "Use when user says backlinks, link profile, referring domains, anchor text, toxic links, link gap, link building, disavow, or backlink audit" clause gives broad natural-term coverage a user would actually say.	3 / 3
Distinctiveness Conflict Risk	A clear SEO-backlink niche with distinct triggers unlikely to fire for unrelated skills; uses third-person voice ("Backlink profile analysis", "Works with") with no first/second person.	3 / 3
	Total	12 / 12 Passed
