Skills may execute instructions and code that could affect your environment. Marketplace scans reduce risk but do not guarantee safety. Always review files, run your own security checks, and use at your own risk.

I understand these skills can contain unsafe or unintended behavior, and I will review and security-scan before use. No warranty, suitability, or outcome is guaranteed.

# E-Commerce Engineering

Build transactional systems for online retail: catalogs, carts, inventory, orders.

## Process

1. Design product catalog schema: categories, filterable attributes, variant combinations, pricing tiers, multi-currency.
2. Implement product search: faceted navigation, full-text search, typo tolerance, synonym expansion, ranking.
3. Build shopping cart: server-side persistence, cart merging, quantity validation, discontinued item removal.
4. Implement inventory management: real-time tracking, soft reservation during checkout, concurrency control.
5. Design checkout flow: address validation, shipping selection (real-time rates), tax computation, order summary.
6. Build order processing state machine: pending, payment-authorized, payment-captured, fulfillment, shipped, delivered.
7. Implement pricing engine: discounts, coupon codes with limits, tiered pricing, bundle pricing, rules.
8. Design returns workflow: RMA generation, return labels, inspection, refund processing, inventory restock.
9. Build notification pipeline: order confirmation, shipping updates, delivery, review requests with templating.
10. Implement analytics: product views, add-to-cart, checkout progression, completion for funnel analysis.

## Technical Standards

- Inventory decrements use optimistic concurrency control with version checks.
- Price calculations use integer arithmetic in minor currency units.
- Cart state survives browser closure, device switching, server restarts.
- Order state transitions validated against state machine.
- Coupon validation checks expiration, limits, minimum order, product eligibility.
- Prices displayed match prices charged; changes communicated before payment.
- Product search returns results within 200ms for up to 100,000 SKUs.

## Verification

- Simulate concurrent purchases; confirm exactly one succeeds.
- Test checkout flow with all payment methods.
- Verify coupon edge cases: expired, exceeded limits, minimum not met.
- Confirm cart merging without duplicates.
- Validate tax calculations for multiple jurisdictions.
