The agent can extract tag and category suggestions from blog post content via frequency and semantic analysis, audit taxonomy for thin tags and bloat, and sync changes to WordPress, Shopify, Ghost, Strapi, or Sanity via their native APIs. Invoke when the user needs to manage, suggest, or audit blog tags and categories across supported CMS platforms.

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
