API capability pack for bounded Shippo shipping operations against https://api.goshippo.com only. Enroll a Shippo API token connection named shippo using Authorization: ShippoToken <token>; no credential is embedded in the manifest. The pack reads and creates addresses, parcels, shipments/rates, label transactions, tracking status, orders, and refunds for ecommerce shipping workflows. It bundles a scheduled shipping operations digest, a shipment/rate brief, a tracking brief, an approval-gated rate-shopping workflow, and an always-approval label purchase workflow. Writes are limited to one address, parcel, shipment, label transaction, or refund at a time. The pack intentionally excludes carrier-account mutation, batches, pickups, manifests, customs write helpers, webhooks, OAuth/platform account management, arbitrary API passthrough, and credential-bearing arguments.
