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.

Audit WooCommerce coupons for expired, never-used, or usage-exhausted codes and delete them in batch after confirmation. Reduces coupon table bloat and prevents confusion from stale codes. Includes dry-run preview listing every coupon to be deleted.
| 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 without deleting |
format | string | no | human | Output format: human or json |
delete_expired | bool | no | true | Delete coupons past their date_expires |
delete_zero_use | bool | no | false | Delete coupons that have never been used (use with caution) |
delete_usage_exhausted | bool | no | true | Delete coupons where usage_count >= usage_limit |
expired_before | string | no | <today> | Only delete coupons that expired before this date |
force_delete | bool | no | true | Permanently delete (bypass trash) |
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 permanently deletes coupons. Deleted coupons cannot be recovered. Always run with dry_run: true first (the default) and review the list carefully. Do not use delete_zero_use: true without verifying those coupons are not in active email campaigns.
Step 1 — Fetch all coupons
GET /wp-json/wc/v3/coupons?per_page=100&page=1Extract: id, code, discount_type, amount, date_expires, usage_count, usage_limit, date_created
Step 2 — Classify coupons for deletion
date_expires != null and date_expires < now (and < expired_before)usage_count == 0 (if delete_zero_use: true)usage_limit > 0 and usage_count >= usage_limitStep 3 — Preview or delete
If dry_run: true: list coupons to be deleted. Stop.
If dry_run: false and confirmed:
DELETE /wp-json/wc/v3/coupons/{id}?force=<force_delete>GET /wp-json/wc/v3/coupons — list all coupons
DELETE /wp-json/wc/v3/coupons/{id} — delete individual couponWooCommerce 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.
