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.

Segment all customers by their total_spent value into configurable Bronze, Silver, and Gold tiers, then write the tier label as a meta_data field on each customer record. Useful for loyalty programs, email segmentation, and B2C personalization. Includes dry-run preview before any writes.
| Parameter | Type | Required | Default | Description |

format | string | no | human | Output format: human or json |
silver_threshold | number | no | 200 | Minimum total_spent (store currency) for Silver tier |
gold_threshold | number | no | 1000 | Minimum total_spent (store currency) for Gold tier |
meta_key | string | no | _loyalty_tier | The meta_data key to write on each customer |

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 4 executes customer meta writes. Always run with dry_run: true first (the default) and confirm the tier distribution preview before tagging live. Writing a meta field is non-destructive — re-running the skill updates the tier — but verify the threshold values match your program rules.
Step 1 — Fetch all customers
GET /wp-json/wc/v3/customers
?role=<role>
&orderby=registered_date
&order=asc
&per_page=100
&page=1Extract per customer: id, first_name, last_name, email, total_spent, orders_count Paginate until response length < 100. Note total from X-WP-Total header.
Step 2 — Compute tier for each customer
if total_spent >= gold_threshold:
tier = gold_label
elif total_spent >= silver_threshold:
tier = silver_label
else:
tier = bronze_labelStep 3 — Preview
If dry_run: true: output tier distribution summary and sample table, then stop.
Step 4 — Write tier meta
If dry_run: false and user has confirmed:
PUT /wp-json/wc/v3/customers/{id}
Body: {
"meta_data": [
{ "key": "<meta_key>", "value": "<tier_label>" }
]
}Process in batches (sequential PUTs, not batch endpoint — customer batch is not available in WC core). Emit progress after every 50 customers.
GET /wp-json/wc/v3/customers — list all customers with spend data
PUT /wp-json/wc/v3/customers/{id} — write loyalty tier meta 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.
