blog-taxonomy

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".

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)
• 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) {
    edges {
      node { id title tags }
    }
  }
}

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

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}

Strapi v4+ uses the data wrapper. 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/v2024-01-01/data/mutate/{dataset}
Body: {"mutations": [{"create": {"_type": "tag", "name": "Tag", "slug": {"current": "tag"}}}]}
Authorization: Bearer {token}

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	Recommend noindex or merge
Orphan tags	0 posts	Recommend deletion
Tag bloat	> 50 total tags	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 < 3 posts (poor user experience, weak SEO signal)
• Medium: tag bloat over 50 (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. Add noindex to tag archives with < 5 posts

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	Base URL of the CMS	https://example.com
CMS_API_KEY	Authentication credential	Application password, API token, or key

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, and $CMS_API_KEY at runtime.

Error Handling

• Missing environment variables: If CMS_TYPE, CMS_URL, or CMS_API_KEY is unset, report which variable is missing and provide the expected format
• Invalid credentials: If the CMS API returns 401/403, report "Authentication failed - check 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, wait 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
