name: blog-taxonomy description: > Extract, suggest, and sync tags and categories for blog posts across all major CMS platforms. Supports WordPress REST API, Shopify GraphQL, Ghost Content API, Strapi REST/GraphQL, and Sanity GROQ. Generates tag suggestions from content analysis (keyword frequency, heading extraction, semantic grouping), enforces minimum post-count thresholds to prevent thin tag archives, and syncs taxonomy via authenticated API calls. Use when user says "tags", "categories", "taxonomy", "tag suggestions", "sync tags", "WordPress tags", "Shopify tags". user-invokable: true argument-hint: "[suggest|sync|audit] [file-or-cms]" license: MIT

Blog Taxonomy

Manage tags, categories, and topic clusters across CMS platforms.

Commands

Command	Purpose
/blog taxonomy suggest <file>	Extract candidate tags and categories from content
/blog taxonomy sync <cms>	Push taxonomy to CMS via authenticated API
/blog taxonomy audit [directory]	Check for thin tags, orphan tags, taxonomy bloat

Tag Suggestion Workflow

Step 1: Parse Content Structure

Read the target file and extract:

• All H2 and H3 headings (primary topic signals)
• Bold and italic phrases (emphasis signals)
• Existing frontmatter tags/categories if present

Step 2: Frequency Analysis

Scan the body text for high-frequency phrases:

• 1-word terms: minimum 4 occurrences (excluding stop words)
• 2-word phrases: minimum 3 occurrences
• 3-word phrases: minimum 2 occurrences

Exclude common non-tag words: articles, prepositions, conjunctions, pronouns.

Step 3: Semantic Grouping

Group related candidates into clusters:

• Merge singular/plural variants (keep the more common form)
• Merge hyphenated and non-hyphenated forms
• Group synonyms under the highest-frequency term

Step 4: Deduplicate and Rank

• Fuzzy match on slugified names (Levenshtein distance <= 2)
• Do not auto-merge short slugs under 5 characters using Levenshtein alone; require token overlap or manual review
• Score each candidate: (frequency * 2) + (heading_presence * 5) + (emphasis * 1)
• Return top 5-10 ranked suggestions

Output Format

## Tag Suggestions: [Post Title]

| Rank | Tag | Score | Source |
|------|-----|-------|--------|
| 1 | content-marketing | 18 | H2 + 6 mentions |
| 2 | seo-strategy | 14 | H3 + 4 mentions |
| 3 | keyword-research | 11 | 5 mentions + bold |

### Suggested Categories
- Primary: [best-fit category]
- Secondary: [optional second category]

CMS Adapters

Adapter Overview

CMS	API Type	Auth Method	Tags Model
WordPress	REST	Application Passwords (base64)	First-class entities with IDs
Shopify	GraphQL (Admin API)	Admin API access token	String array on Article
Ghost	REST (Admin API)	API key with JWT signing	First-class entities
Strapi	REST or GraphQL	API token (Bearer)	User-defined content type
Sanity	GROQ / Mutations	Project token (Bearer)	Document type

WordPress Adapter

List tags:

GET {CMS_URL}/wp-json/wp/v2/tags?per_page=100&search={keyword}
Authorization: Basic {base64(username:app_password)}

Create tag:

POST {CMS_URL}/wp-json/wp/v2/tags
Body: {"name": "Tag Name", "slug": "tag-name", "description": "Optional"}

List categories (hierarchical, supports parent field):

GET {CMS_URL}/wp-json/wp/v2/categories?per_page=100

Create category:

POST {CMS_URL}/wp-json/wp/v2/categories
Body: {"name": "Category", "slug": "category", "parent": 0}

Assign tags to post:

POST {CMS_URL}/wp-json/wp/v2/posts/{id}
Body: {"tags": [1, 2, 3], "categories": [4]}

Pagination: follow X-WP-TotalPages header for full listing.

Shopify Adapter

Tags on Shopify are string arrays on the Article object, not first-class entities.

Update article tags (GraphQL Admin API):

mutation {
  articleUpdate(id: "gid://shopify/Article/123", article: {
    tags: ["tag-one", "tag-two", "tag-three"]
  }) {
    article { id tags }
    userErrors { field message }
  }
}

List all tags in use (GraphQL):

{
  articles(first: 250, after: $cursor) {
    pageInfo { hasNextPage endCursor }
    edges {
      node { id title tags }
    }
  }
}

Auth header: X-Shopify-Access-Token: {token}

Pagination: loop while pageInfo.hasNextPage is true, passing endCursor as the next $cursor.

Note: REST API marked legacy Oct 2024. GraphQL required for new apps since Apr 2025.

Ghost Adapter

List tags:

GET {CMS_URL}/ghost/api/admin/tags/?limit=all
Authorization: Ghost {jwt_token}

Create tag:

POST {CMS_URL}/ghost/api/admin/tags/
Body: {"tags": [{"name": "Tag Name", "slug": "tag-name"}]}

JWT generation: sign with admin API key (id:secret format), iat = now, exp = 5 min, audience = /admin/.

Strapi Adapter

Endpoint auto-generated from content types. Typical setup:

GET {CMS_URL}/api/tags?pagination[pageSize]=100
POST {CMS_URL}/api/tags
Body: {"data": {"name": "Tag Name", "slug": "tag-name"}}
Authorization: Bearer {api_token}

Pagination: increment pagination[page] until all pages are exhausted.

Strapi v4 responses use the data wrapper with attributes; Strapi v5 uses a flatter response shape. Detect the version or normalize both shapes before deduplication. Check your content type schema for field names.

Sanity Adapter

Query tags (GROQ):

*[_type == "tag"] { _id, name, slug }

Create tag (Mutations API):

POST https://{project_id}.api.sanity.io/{SANITY_API_VERSION}/data/mutate/{dataset}
Body: {"mutations": [{"create": {"_type": "tag", "name": "Tag", "slug": {"current": "tag"}}}]}
Authorization: Bearer {token}

Default SANITY_API_VERSION to a current tested API date supplied by the project environment; do not hard-code it in generated requests.

Taxonomy Audit Workflow

Step 1: Inventory

Scan all posts in the target directory (or fetch from CMS). Build a map:

• tag_name -> [list of post files/IDs using this tag]
• category_name -> [list of post files/IDs]

Step 2: Health Checks

Check	Threshold	Action
Thin tag archives	< 5 posts per tag	Review for merge or noindex after traffic, intent, and link checks
Orphan tags	0 posts	Recommend deletion
Tag bloat	More than max(50, post_count * 0.25) total tags, adjusted for taxonomy purpose	Recommend consolidation
Category depth	> 3 levels	Recommend flattening
Uncategorized posts	No category assigned	Assign to appropriate category
Duplicate slugs	Same slug, different name	Merge into canonical version

Step 3: Recommendations

Group findings by priority:

• Critical: orphan tags creating empty archive pages (crawl waste)
• High: thin tags with < 5 posts after traffic, intent, and link checks
• Medium: tag bloat above the scaled threshold (diluted taxonomy, harder to navigate)
• Low: naming inconsistencies (mixed case, hyphen vs space)

Output Format

## Taxonomy Audit: [Site/Directory]

**Total tags**: [n] | **Total categories**: [n]
**Healthy**: [n] | **Thin**: [n] | **Orphan**: [n]

### Critical Issues
- [orphan tags list]

### Recommendations
1. Merge [tag-a] and [tag-b] (same topic, [n] combined posts)
2. Delete orphan tags: [list]
3. Merge or noindex tag archives with < 5 posts only after traffic, intent, and link checks

Site-Wide Guidelines

• Aim for 5-10 main categories per site (broad topics)
• Tags should have at least 5 posts before creating an archive page
• Use consistent slug format: lowercase, hyphen-separated
• Every post needs exactly 1 primary category
• Tags per post: 3-8 recommended, never exceed 15

Environment Variables

Variable	Purpose	Example
CMS_TYPE	Platform identifier	wordpress, shopify, ghost, strapi, sanity
CMS_URL	HTTPS base URL of the CMS	https://example.com
CMS_ALLOWED_HOSTS	Optional comma-separated allowlist for CMS hosts	example.com,admin.example.com
CMS_USERNAME	WordPress username when using Application Passwords	editor@example.com
CMS_API_KEY	Authentication credential	WordPress app password, API token, or key
SANITY_API_VERSION	Sanity API date for mutations	v2026-07-01

These must be set in the shell environment. Never store credentials in files or commit them to version control. The skill reads them via $CMS_TYPE, $CMS_URL, $CMS_USERNAME, $CMS_API_KEY, and optional platform-specific variables at runtime.

Security rule for CMS calls: require HTTPS, allow only http and https parsing paths but send authenticated requests over HTTPS only, resolve DNS and block loopback/private/link-local/reserved IPs, validate redirects with the same checks or disable redirects, cap timeouts at 10 seconds, and enforce CMS_ALLOWED_HOSTS when set.

Error Handling

• Missing environment variables: If CMS_TYPE, CMS_URL, or CMS_API_KEY is unset, or if WordPress lacks CMS_USERNAME, report which variable is missing and provide the expected format
• Invalid credentials: If the CMS API returns 401/403, report "Authentication failed - check CMS_USERNAME/CMS_API_KEY" and do not retry
• Connection timeouts: If the CMS endpoint is unreachable after 10 seconds, report the timeout and suggest checking CMS_URL
• Duplicate tag slugs: If a tag already exists on the CMS, skip creation and note "Tag already exists: [name]"
• Rate limits: If the CMS API returns 429, honor Retry-After when present; otherwise use exponential backoff and retry once. Report if the limit persists
• Unsupported CMS: If CMS_TYPE is not one of the 5 supported platforms, list the valid options and exit
