Quality

Content

75%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.

The body is a well-sequenced, actionable SEO validation workflow with concrete criteria, a copy-paste report template, and executable commands for the optional live check. It is efficient rather than padded, though a few prose passages could be trimmed and some detailed checklists could be split into reference files now that no bundle exists.

Suggestions

Trim the narrative prose in the link-dedup and FLOW sections to tight criteria, or move the detailed FLOW evidence-triple rules into a reference file (the body already points to skills/blog/references/flow-alignment.md — make that the canonical location).

Add an explicit validate->fix->retry loop or a 're-run failed checks after applying fixes' note in Step 11 so the workflow has a clear feedback loop, lifting workflow_clarity toward 5.

Consider extracting the per-area criteria tables (Steps 2-10) into a bundled reference file under references/ so SKILL.md reads as an overview, improving progressive_disclosure now that the skill exceeds 50 lines with no bundle.

DimensionReasoningScore

Conciseness

The body is mostly tight, actionable tables (checks vs pass criteria) with little concept-explanation Claude doesn't need, but a few prose passages could be trimmed — e.g. 'Historical third-party anchor-text tests suggest repeated identical body links have limited value. Prefer Google's guidance: mak...' and the narrative around link dedup scoring — so it sits at 'efficient with minor instances of over-explanation' rather than fully lean. It is not a 3 because padding is the exception, not the rule, and not a 5 because those prose passages do not each earn their tokens.

4 / 5

Actionability

Provides concrete, specific guidance throughout — exact character ranges (40-60, 50-60 ideal; under 70; under 200), named tags, a copy-paste-ready report template, and executable commands for the optional live check ('python3 skills/blog-google/scripts/run.py google_auth --check --json'). It is not a 5 because much of the guidance is judgment-based pass/fail criteria rather than copy-paste code covering common cases, but it is well above a 3 since commands and the report template are directly executable.

4 / 5

Workflow Clarity

An explicit 11-step sequence (Step 1 through Step 11) with built-in checklists (the criteria tables) and validation checkpoints (URL safety checks in Step 1, JSON-LD validity, structured-data date consistency) and a defined PASS/FAIL/WARN/N/A output. It is not a 5 because there is no explicit validate->fix->retry error-recovery loop, and not a 3 because checkpoints are present and the sequence is unambiguous; the destructive/batch cap does not apply since this is a read-only validation/reporting skill.

4 / 5

Progressive Disclosure

Well-organized into clearly headed steps with a defined report section and clearly signaled one-level pointers ('See skills/blog/references/flow-alignment.md', 'For a one-shot prompt-driven check, see /blog flow optimize'). No bundle files exist in this skill (references/scripts/assets absent), so all content is inlined in a 236-line SKILL.md; it is not a 5 because some detailed checklists (e.g. FLOW evidence triple, link dedup) could live in separate reference files, and not a 3 because structure is good and the references that do appear are clearly signaled.

Description

100%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.

The description is comprehensive, concrete, and explicitly pairs a detailed 'what' with a rich set of natural 'when' triggers in third person. Its only weakness is verbosity — the checklist of areas is long — but the content is dense specifics rather than fluff, so it does not cross into padding.

DimensionReasoningScore

Specificity

Lists multiple concrete actions across the full SEO surface — 'title tag length and keyword placement', 'meta description quality', 'heading hierarchy and keyword density', 'internal/external link audit with anchor text analysis', 'canonical URL verification', 'Open Graph meta tags (og:title, og:description, og:image)', 'Twitter Card validation', 'structured data presence and validity', 'URL structure optimization', and 'image alt text presence' — plus 'Produces prioritized fix list with specific recommendations', giving comprehensive coverage rather than the 1-2 actions of a score-3 anchor.

5 / 5

Completeness

Explicitly answers both 'what' (post-writing SEO validation with a pass/fail checklist covering enumerated areas, producing a prioritized fix list) and 'when' ('Use when user says ...' with concrete trigger phrases), matching the score-5 anchor that clearly and explicitly answers both with concrete triggers.

5 / 5

Trigger Term Quality

Comprehensive natural trigger phrases a user would actually say — 'seo check', 'check seo', 'validate seo', 'blog seo', 'seo validation', 'on-page seo', 'title tag check', 'meta description check', 'heading check', 'link audit' — covering synonyms and component-level variations, matching the score-5 anchor's comprehensive coverage.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (on-page blog SEO validation post-writing) with distinct, specific triggers unlikely to fire for unrelated skills, matching the score-5 anchor's clear niche with minimal conflict risk.
