Build, customize, and deploy Ghost CMS themes. Use whenever the user mentions Ghost themes, Ghost CMS, Handlebars templates (.hbs), Ghost Admin, membership/subscription integration, custom settings, or the content API — even without saying "theme". Trigger on: building a blog theme, creating a Ghost site, editing .hbs templates, member-only content, hero sections, routing (routes.yaml), image optimization, dark mode, search, deploy, gscan validation, JSON-LD/SEO, or any mention of {{ghost_head}}, {{ghost_foot}}, {{#foreach}}, {{#get}}, {{img_url}}, {{asset}}, @custom, @member, or Portal. Also use to modify, extend, or debug an existing theme. Also trigger on Koenig editor cards and .kg-* card styling (kg-image-card, kg-gallery-card, kg-bookmark-card, kg-callout-card, kg-toggle-card, kg-header-card, kg-signup-card), card_assets, cards.min.css, and breakout/wide/full-width card layout.

Content

100%

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

This is an exceptionally well-structured skill that maximizes information density while maintaining clarity. The routing table is a standout pattern for progressive disclosure, efficiently mapping user intents to specific reference files. The Quick Start provides concrete, executable steps with important guardrails (e.g., always copy base template, activate 'dev-theme' not the folder name), and the Common Workflows section elegantly shows how to combine references for multi-faceted tasks.

DimensionReasoningScore

Conciseness

The content is lean and efficient. It assumes Claude's competence with Handlebars, build tools, and web development concepts. No unnecessary explanations of what Ghost CMS is or how templating works. Every section earns its place — the routing table is particularly token-efficient for the amount of information it conveys.

3 / 3

Actionability

Provides concrete, copy-paste-ready bash commands for setup, specific file paths, exact URLs (localhost:2368/ghost/), and precise instructions like activating 'dev-theme' in Ghost Admin. The routing table maps specific tasks to specific reference files with key topic keywords. Common workflows give exact helper names and file references.

3 / 3

Workflow Clarity

The Quick Start section has a clear sequence: copy template → install → build → update package.json → run setup script → start dev → complete wizard → activate theme. The 'Common Workflows' section provides clear multi-file reading sequences for each task type. The explicit instruction 'Do not write Ghost theme files from scratch' is a clear guardrail. Validation is addressed via gscan references.

3 / 3

Progressive Disclosure

Excellent progressive disclosure with a well-organized routing table pointing to 14 reference files, each clearly labeled with key topics. The instruction to 'read only the relevant reference file(s)' and 'Most tasks need 1-2 files, not all 12' is exemplary. Common Workflows section shows exactly which references to combine for specific tasks, all one level deep.

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.

This is an excellent skill description that thoroughly covers the Ghost CMS theming domain with highly specific actions, extensive trigger terms, and clear guidance on when to use it. The description is comprehensive without being vague, listing concrete Ghost-specific helpers, file types, and concepts that make it unmistakable. The only minor concern is that the description is quite long, but the density of useful trigger information justifies the length.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: build, customize, deploy themes, edit .hbs templates, membership/subscription integration, routing, image optimization, dark mode, search, gscan validation, JSON-LD/SEO, debug existing themes, and Koenig editor card styling.

3 / 3

Completeness

Clearly answers both 'what' (build, customize, deploy Ghost CMS themes; modify/extend/debug existing themes) and 'when' with an extensive explicit 'Use whenever...' and 'Trigger on:' clause covering numerous specific scenarios and keywords.

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say, including file extensions (.hbs), tool names (Ghost CMS, Ghost Admin, gscan), template helpers ({{ghost_head}}, {{#foreach}}, {{img_url}}), CSS class patterns (.kg-*), config files (routes.yaml), and conceptual terms (blog theme, member-only content, dark mode, hero sections).

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with Ghost CMS-specific terminology, Handlebars template syntax, Ghost-specific helpers, Koenig editor cards, and gscan validation. Very unlikely to conflict with generic web development or other CMS skills due to the specificity of the Ghost ecosystem terms.
