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.

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=1Aggregate units sold and revenue per product_id from line_items.
Step 2 — Fetch refunded orders
GET /wp-json/wc/v3/orders
?status=refunded&after=<date_after>T00:00:00Z&before=<date_before>T23:59:59Z&per_page=100&page=1Aggregate refunded units and amounts per product_id from line_items.
Step 3 — Compute rates
refund_rate = refunded_units / (sold_units + refunded_units) * 100Flag products where refund_rate > high_rate_threshold.
Step 4 — Export
GET /wp-json/wc/v3/orders — completed and refunded order scan
GET /wp-json/wc/v3/orders/{id}/refunds — detailed refund line itemsWooCommerce 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.
