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.

Analyze whether the shipping revenue collected on WooCommerce orders (via shipping_total) aligns with your shipping zone rate configuration. Identifies zones or methods where shipping is underpriced relative to actual carrier costs, and quantifies the net shipping P&L. Read-only.
| 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 | false | No effect — read-only skill |
format | string | no | human | Output format: human or json |
date_after | string | yes | — | Start date (YYYY-MM-DD) |
date_before | string | yes | — | End date (YYYY-MM-DD) |
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.
Read-only skill — no mutations are executed. Safe to run at any time.
Step 1 — Fetch completed orders
GET /wp-json/wc/v3/orders
?status=completed&after=<date_after>T00:00:00Z&before=<date_before>T23:59:59Z&per_page=100&page=1Extract: id, shipping_total, shipping_tax, shipping_lines[].method_id, shipping_lines[].method_title, shipping_address.country
Step 2 — Fetch shipping zones and methods
GET /wp-json/wc/v3/shipping/zonesFor each zone: GET /wp-json/wc/v3/shipping/zones/{id}/methods
Build map: method_id → flat_rate cost
Step 3 — Aggregate by shipping method
Group orders by shipping_lines[].method_id. For each group: total_collected = sum(shipping_total), order_count, avg_collected.
Step 4 — Export analysis
GET /wp-json/wc/v3/orders — order shipping totals
GET /wp-json/wc/v3/shipping/zones — shipping zone list
GET /wp-json/wc/v3/shipping/zones/{id}/methods — rates per zoneWooCommerce 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.
