web-commerce

v0.1.2

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.

Included Skills5

commerce-gold-standard-rubricskills/commerce-gold-standard-rubric/SKILL.md

Score a scaffolded commerce integration against the seven-dimension gold-standard rubric and run the BUILD-measure-fix iteration loop until it passes. Use after scaffolding a provider track, before calling it done. Each dimension is a falsifiable test; a live provider-sandbox test is required beyond the static checks.

payment-lifecycle-contractskills/payment-lifecycle-contract/SKILL.md

Understand and extend the thin shared contract every provider track implements — the payment-lifecycle interface plus advertised capabilities. Use when adding a provider, wiring a track to the contract, or deciding what belongs in the shared seam vs a track. The ONLY cross-provider abstraction; catalog/cart/inventory are track-specific.

pos-reconciliation-loopskills/pos-reconciliation-loop/SKILL.md

Reconcile online inventory/catalog with an in-store POS (Square), keeping the POS as the source of truth. Use when a storefront's online store must mirror in-store stock. One-way sync driven by catalog/inventory webhooks, de-duped by event id — never bidirectional. Square-specific; Shopify inverts and Stripe has no catalog.

provider-track-selectionskills/provider-track-selection/SKILL.md

Choose the commerce provider (Stripe / Square / Shopify) and the tier (static hosted-checkout vs framework embedded-SDK) for a site, then point at the right template set. Use at the START of any commerce integration, before scaffolding. Routes on how the merchant's inventory truth already lives and the site's runtime.

webhook-hardeningskills/webhook-hardening/SKILL.md

Harden a commerce webhook handler: verify the provider signature with a constant-time compare BEFORE parsing the body, then de-duplicate retried deliveries by provider event id. Use when writing or reviewing any Stripe/Square/Shopify webhook receiver. Two invariants (verify-before-parse, event-id idempotency) that are non-negotiable.
