seo-cluster

SERP-based semantic topic clustering for content architecture planning. Groups keywords by actual Google SERP overlap (not text similarity), designs hub-and-spoke content clusters with internal link matrices, and generates interactive visualizations. Optionally executes content creation if claude-blog is installed. Use when user says "topic cluster", "content cluster", "semantic clustering", "pillar page", "hub and spoke", "content architecture", "keyword grouping", or "cluster plan".

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-structured, actionable workflow with clear sequencing, concrete thresholds/commands, and good progressive disclosure through three real reference files. It loses a point mainly to mild redundancy and a referenced template file absent from the bundle.

Suggestions

Trim the opening paragraph (it repeats the frontmatter description) and consider whether the Quick Reference table adds enough beyond the detailed Planning Workflow section to justify its tokens.

Either include `templates/cluster-map.html` in the bundle or note explicitly that it is expected at the plugin root, so the Step 6 reference resolves to a real file.

For batch/destructive steps (e.g., content execution, DataForSEO calls), phrase validation as explicit validate→fix→retry feedback loops to push workflow clarity higher.

Dimension	Reasoning	Score
Conciseness	Mostly efficient — dense tables, specific thresholds, and exact commands that assume Claude's competence — but the intro paragraph echoes the frontmatter description and the Quick Reference table previews detail elaborated later, minor redundancy that could be trimmed.	4 / 5
Actionability	Provides concrete executable guidance — SERP overlap thresholds, JSON adjacency/schema examples, and exact `scripts/claude-seo run dataforseo_costs.py ...` commands — with a minor gap: `templates/cluster-map.html` is referenced but not present in the bundle.	4 / 5
Workflow Clarity	Steps 1–6 are clearly sequenced with real checkpoints (DataForSEO cost-check approval gate, resume-state scan, cannibalization check, thorough error-handling table), though few are framed as strict validate→fix→retry feedback loops.	4 / 5
Progressive Disclosure	Three well-signaled one-level-deep references ("Load `references/serp-overlap-methodology.md` for the full algorithm", etc.) verified real and non-nested, with content appropriately split; the missing `templates/cluster-map.html` and a fairly long inline body keep it just below a 5.	4 / 5

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 exemplary: concrete third-person actions, comprehensive natural trigger terms, and an explicit what-and-when structure. It is clearly distinguishable from other SEO skills and carries no vague padding.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions in third person — "Groups keywords by actual Google SERP overlap", "designs hub-and-spoke content clusters with internal link matrices", "generates interactive visualizations", "Optionally executes content creation" — giving comprehensive coverage with no vague filler.	5 / 5
Completeness	Explicitly answers both what (SERP-based clustering, hub-and-spoke design, visualizations, optional execution) and when ("Use when user says...") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Provides comprehensive natural trigger phrases users would actually say — "topic cluster", "content cluster", "semantic clustering", "pillar page", "hub and spoke", "content architecture", "keyword grouping", "cluster plan" — including synonyms and phrasings.	5 / 5
Distinctiveness Conflict Risk	Occupies a clear niche (SERP-overlap SEO topic clustering) with distinctive triggers unlikely to fire for unrelated skills; minimal conflict risk.	5 / 5
