Product Tag Bulk Update

Purpose

Add or remove one or more tags from a bulk-filtered set of WooCommerce products. Filters include category, price range, stock status, or existing tags. Useful for tagging seasonal collections, sale items, or featured products in bulk. Includes dry-run preview before any products are updated.

Prerequisites

• WooCommerce store with REST API enabled
• Consumer Key with Read/Write scope
• Minimum WooCommerce version: 3.5.0

Parameters

Authentication

WooCommerce uses OAuth 1.0a for HTTP and Basic Auth over HTTPS.

For HTTPS stores (recommended):

Authorization: Basic base64(consumer_key:consumer_secret)

For HTTP stores (development only): Use OAuth 1.0a — include oauth_consumer_key, oauth_nonce, oauth_signature, oauth_signature_method=HMAC-SHA1, oauth_timestamp, oauth_version=1.0

Never log or output consumer_key or consumer_secret values.

See docs/AUTHENTICATION.md for full setup instructions.

Safety

Step 3 updates product tags on multiple products. Always run with dry_run: true first (the default). Verify the product list in the preview before applying.

Workflow Steps

Step 1 — Resolve tag names

GET /wp-json/wc/v3/products/tags?per_page=100&page=1

Build tag ID → name lookup for display in preview.

Step 2 — Fetch filtered products

GET /wp-json/wc/v3/products
  ?status=publish&per_page=100&page=1
  [&category=<filter_category_id>]
  [&tag=<filter_tag_id>]
  [&stock_status=<filter_stock_status>]

Filter client-side by price range if specified. Extract per product: id, name, sku, tags

Step 3 — Preview or update tags

Compute new tag list:

• add: merge tag_ids into existing tags (avoid duplicates)
• remove: subtract tag_ids from existing tags

If dry_run: true: output preview table and stop.

If dry_run: false and confirmed:

PUT /wp-json/wc/v3/products/{id}
  Body: { "tags": [{ "id": <tag_id> }, ...] }

API Endpoints Used

GET  /wp-json/wc/v3/products/tags    — resolve tag IDs to names
GET  /wp-json/wc/v3/products         — fetch filtered product set
PUT  /wp-json/wc/v3/products/{id}    — update product tags

Pagination Strategy

WooCommerce REST API uses page/per_page pagination (not cursor-based).

Standard pattern:

page = 1
while True:
  response = GET /endpoint?per_page=100&page=page
  process(response)
  if len(response) < 100: break
  page += 1

Maximum per_page is 100 for most endpoints. The X-WP-Total and X-WP-TotalPages response headers report totals. Always read X-WP-TotalPages on the first request to estimate job size.

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

STARTUP:

╔══════════════════════════════════════════╗
║  SKILL: woo-product-tag-bulk-update      ║
║  STORE: <store_url>                      ║
║  TIME:  <ISO-8601 UTC>                   ║
║  MODE:  <DRY RUN | LIVE>                 ║
╚══════════════════════════════════════════╝

PER-OPERATION (emit after each API call batch):

[N/TOTAL] <METHOD> <endpoint> → <result_count> records | params: <key>=<val>

COMPLETION (human format):

╔══════════════════════════════════════════╗
║  COMPLETE: woo-product-tag-bulk-update   ║
║  RECORDS PROCESSED: <n>                  ║
║  OUTPUT: stdout                          ║
╚══════════════════════════════════════════╝

COMPLETION (json format):

{
  "skill": "woo-product-tag-bulk-update",
  "store": "<store_url>",
  "completed_at": "<ISO-8601>",
  "records_processed": <n>,
  "output_file": null,
  "dry_run": <bool>
}

Output Format

Human format: a table listing each product, its current tags, and the new tag set.

Error Handling

Best Practices

• Always run with dry_run: true first (the default). Confirm the product list before applying.
• Use tag IDs (not names) in tag_ids — fetch them from WooCommerce → Products → Tags.
• For adding seasonal tags: schedule this skill at the start of the season; use remove at the end.
