blog-cluster

Semantic topic cluster planning and automated execution engine for claude-blog. Performs SERP-based keyword research, groups keywords by search intent and SERP overlap, builds a hub-and-spoke cluster architecture, generates an interactive SVG cluster map, and executes the full cluster by orchestrating blog-write calls with shared cluster context and automatic internal-link injection. Fills the strategy-to-execution gap: blog-strategy plans the blueprint, blog-cluster builds the house. Use when user says "blog cluster", "topic cluster", "content cluster", "cluster plan", "cluster execute", "pillar content", "hub and spoke", "content ecosystem", "cluster map".

Quality

Content

77%

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

The body is highly actionable and the multi-phase workflow is clearly sequenced with validation checkpoints. The main weaknesses are mild redundancy across sections and one broken bundle reference plus detail that could be pushed into reference files.

Suggestions

Fix or remove the dangling reference to skills/blog/references/flow-alignment.md (Step 3 of the Execute Phase), which does not exist in the bundle.

Move the full cluster-plan.json schema and/or the Quality Gates and Error Handling tables into an existing reference file to slim the SKILL.md body.

De-duplicate failure-handling guidance, which currently appears in both the Execute Phase steps and the Error Handling table.

DimensionReasoningScore

Conciseness

The body is dense and skill-specific with no padding about concepts Claude already knows, but it restates several points across the Plan/Execute narrative, the Quality Gates table, and the Error Handling table, so it could be tightened further.

2 / 3

Actionability

It provides concrete, executable guidance: a full cluster-plan.json schema, exact word-count ranges, a file tree, internal-link rules, XSS-escaping rules for the SVG map, and explicit failure-handling actions.

3 / 3

Workflow Clarity

Plan and Execute phases are clearly sequenced with numbered steps and explicit validation checkpoints ('Validate JSON structure', 'wait for explicit user approval', stop-the-batch-on-quality-failure) including a feedback loop for batch operations.

3 / 3

Progressive Disclosure

The overview signals three one-level-deep references that all exist on disk, but the body also points to a non-existent skills/blog/references/flow-alignment.md and inlines substantial detail (full JSON schema, Quality Gates, Error Handling tables) that could live in the reference files.

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.

The description is specific, trigger-rich, complete (what + when), and distinct from sibling claude-blog skills. It is a near-textbook example of the rubric's good_overall_examples.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'SERP-based keyword research', 'groups keywords by search intent and SERP overlap', 'builds a hub-and-spoke cluster architecture', 'generates an interactive SVG cluster map', 'orchestrating blog-write calls' — rather than vague language.

3 / 3

Completeness

Explicitly answers both what the skill does (capability sentences) and when to use it (an explicit 'Use when user says ...' trigger clause).

3 / 3

Trigger Term Quality

The 'Use when user says' clause enumerates natural phrases users would actually say — 'blog cluster', 'topic cluster', 'cluster plan', 'pillar content', 'hub and spoke', 'content ecosystem', 'cluster map'.

3 / 3

Distinctiveness Conflict Risk

The cluster-planning-and-execution niche and the specific trigger phrases ('cluster plan', 'hub and spoke') make it unlikely to fire for the wrong skill.
