A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Set or update a single meta_data key-value pair across a bulk-filtered set of WooCommerce products. Useful for adding custom fields (warranty period, supplier code, origin country) or updating plugin-specific meta values in bulk. Includes dry-run preview before any updates.
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
store_url | string | yes | — | Base URL of the WooCommerce store |
consumer_key | string | yes | — | WooCommerce REST API consumer key (ck_...) |
consumer_secret | string | yes | — | WooCommerce REST API consumer secret (cs_...) |
dry_run | bool | no | true | Preview changes without executing |
format | string | no | human | Output format: human or json |
meta_key | string | yes | — | The meta_data key to set (e.g., _supplier_code) |
meta_value | string | yes | — | The value to set for the key |
filter_category_id | int | no | — | Limit to products in this category |
filter_tag_id | int | no | — | Limit to products with this tag |
filter_status | string | no | publish | Product status to filter |
only_if_missing | bool | no | false | Only write if the key doesn't already have a value |
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.
Step 3 writes meta_data fields. Always run with dry_run: true first (the default). Overwriting existing meta values may affect plugin behavior — confirm the meta_key is correct before proceeding.
Step 1 — Fetch filtered products
GET /wp-json/wc/v3/products
?status=<filter_status>&per_page=100&page=1
[&category=<filter_category_id>]
[&tag=<filter_tag_id>]Extract: id, name, sku, meta_data
Step 2 — Evaluate meta_data
For each product, check if meta_key already exists in meta_data. If only_if_missing: true, skip products where the key already has a value.
Step 3 — Preview or execute
If dry_run: true: output preview table and stop.
If dry_run: false and confirmed:
PUT /wp-json/wc/v3/products/{id}
Body: { "meta_data": [{ "key": "<meta_key>", "value": "<meta_value>" }] }GET /wp-json/wc/v3/products — filtered product list
PUT /wp-json/wc/v3/products/{id} — write meta_data fieldWooCommerce 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 += 1Maximum 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.
Claude MUST emit the following output at each stage. This is mandatory.
