ghost-headless-blog: Claude Code skill

A Claude Code skill (packaged as a plugin + marketplace) for implementing a headless Ghost CMS blog in a Next.js App Router site, with battle-tested patterns and copy-paste templates.

Once installed, Claude loads it automatically whenever you ask things like "add a Ghost-powered blog to this site" or when debugging an existing headless Ghost integration (empty blog, stale pages, broken images/cards).

Highlights baked into the skill:

• Direct Content API calls (Accept-Version: v6.0), no @tryghost/content-api dependency
• Server-only credentials (no NEXT_PUBLIC_), all fetching in server components
• ISR (revalidate = 3600) + Ghost webhook for instant purges on publish/update/unpublish/delete
• Full archive coverage: tag archives, author archives, and paged feed archives, all statically generated with dynamicParams for new content
• Author pages: bio, avatar and cover image, location, post count, and social links (X, Facebook, Threads, Bluesky, Mastodon, TikTok, YouTube, Instagram, LinkedIn) normalized from Ghost's stored handles
• Three-tier failure handling: missing env renders an empty blog (build succeeds), a rejected key warns once and shows the empty state, transient 5xx throws so ISR keeps the last good page
• SEO: Ghost meta/og/twitter fields with fallbacks, canonical_url, JSON-LD for BlogPosting, Blog, CollectionPage, and ProfilePage/Person with sameAs social profiles, plus an honest sitemap covering posts, tags, and authors
• Rendering: dangerouslySetInnerHTML + dedicated koenig-card CSS, blur-up images via inline onload, first-image LCP promotion, toggle-card JS re-implementation
• Official docs on tap: a reference workflow for querying Ghost's LLM docs feed (https://docs.ghost.org/llms-full.txt) section by section instead of guessing at API shapes
• Operational pitfalls learned in production (env wipes, domain moves, webhook secret placement, redirecting canonical URLs)

Install

Option A: as a plugin (recommended)

In any Claude Code session:

/plugin marketplace add kasuncfdo/ghost-headless-blog-skill
/plugin install ghost-headless-blog@kasuncfdo-skills

Update later with:

/plugin marketplace update kasuncfdo-skills

Option B: skills CLI (works across agents)

Installs into Claude Code, Cursor, Codex, and other agents supported by the skills ecosystem:

npx skills add kasuncfdo/ghost-headless-blog-skill

Add -g for a global (user-level) install instead of the current project.

Option C: personal skill (no plugin system)

Copy the skill folder into your user skills directory:

git clone git@github.com:kasuncfdo/ghost-headless-blog-skill.git
mkdir -p ~/.claude/skills
cp -R ghost-headless-blog-skill/skills/ghost-headless-blog ~/.claude/skills/

Option D: per-project skill

Ship it with one repo only (teammates get it too):

mkdir -p .claude/skills
cp -R ghost-headless-blog-skill/skills/ghost-headless-blog .claude/skills/

Use

The skill triggers automatically on matching requests, or invoke it explicitly:

/ghost-headless-blog

Typical prompts:

• "Add a headless Ghost blog at /blog to this Next.js site"
• "Add author pages with bios and social links to my Ghost blog"
• "My Ghost blog builds with 0 posts, debug it"
• "Ghost toggle cards / bookmarks render broken in my Next.js blog"

Requirements (for the generated implementation)

• Next.js 15+ (App Router; templates assume params is a Promise)
• A Ghost site (managed or self-hosted) with a Custom Integration (Content API key)
• Hosting that supports ISR + revalidatePath (e.g. Vercel) for the webhook flow
