on-page-seo-checker

Use when the user asks to "audit on-page SEO" or "diagnose why a single page dropped"; scores titles, meta, header structure, keyword placement, links, and images with prioritized fixes. Not for E-E-A-T / publish-readiness scoring — use content-quality-auditor; not for crawl / CWV / indexing — use technical-seo-checker. 页面SEO审计/排名诊断

Quality

Content

82%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 well-structured, actionable, and properly splits detail into clearly signaled one-level reference files with a validated 11-step workflow and decision gates. It is only mildly verbose in a few caveat sections.

DimensionReasoningScore

Conciseness

The body is mostly efficient and assumes Claude's competence (e.g. terse numbered step descriptions), but a few explanatory caveats like the JS-injected JSON-LD false-negative block and keyword-fallback rationale add some length that could be trimmed.

4 / 5

Actionability

Concrete executable commands are present (e.g. `python3 "${CLAUDE_PLUGIN_ROOT}/scripts/connectors/onpage.py" <url>` and the firecrawl fallback), and the 11-step list is specific, though the per-step audit guidance stays descriptive rather than fully copy-paste ready.

4 / 5

Workflow Clarity

A clear 1-11 step sequence with explicit validation checkpoints ("score /10", DONE_WITH_CONCERNS status, decision gates that stop-vs-continue) and error-recovery hints; minor gaps keep it just below a 5.

4 / 5

Progressive Disclosure

The SKILL.md is an overview pointing to four real one-level-deep reference files (audit-example, audit-templates, scoring-rubric, bulk-audit-playbook), each confirmed present and clearly signaled with a labeled link, with no nested-reference chains.

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 concrete, trigger-rich, and clearly distinct from sibling SEO skills via explicit handoff boundaries. It fully answers both what and when, with no vague fluff.

DimensionReasoningScore

Specificity

Lists multiple concrete audited elements — "titles, meta, header structure, keyword placement, links, and images" — plus "prioritized fixes", giving comprehensive concrete actions.

5 / 5

Completeness

Explicitly answers both what (scores the listed on-page elements with prioritized fixes) and when ("Use when the user asks to..."), and adds negative-boundary "Not for..." clauses.

5 / 5

Trigger Term Quality

Captures the natural user phrases "audit on-page SEO" and "diagnose why a single page dropped" with synonyms covering the domain well.

5 / 5

Distinctiveness Conflict Risk

The "Not for E-E-A-T... use content-quality-auditor; not for crawl/CWV/indexing... use technical-seo-checker" carve-out creates a clear niche with minimal conflict risk.
