Add Treeship receipts to an anthropics/commerce-agents deployment: a signed intent and result for every tool call on all three runtimes, the merchant's approval as a signed single-use grant, and a receipt for exactly the cart that went to checkout. One command, one skill; the plugin runs no code of its own.

by Matt Corbett

Web commerce integration specialist — scaffolds production-ready payment/commerce backends (Stripe, Square, or Shopify; one per site) into static or JS-framework sites at full depth: catalog, cart, hosted/embedded checkout, verified webhooks, idempotency, POS/inventory reconciliation, and order handling. Three first-class provider tracks behind a thin shared payment-lifecycle contract — NOT a leaky unified adapter. Generates first-party code (no dormant/deprecated deps), with PCI card-isolation, webhook signature verification, idempotency, and env-only secrets as GENERATED-CODE invariants. The backend-integration lane that plugs into web-design's build pipeline; every payment/PII security verdict routes to ravenclaude-core/security-reviewer. Inherits ravenclaude-core protocols.

by Fluveo

Agent skills for integrating with the Fluveo payments API (Stripe-shaped /v1) over raw HTTP: payment intents, refunds, hosted checkout, payment links, customers, billing, balance.
