Saleor Paper Storefront

Project-specific guide for the Saleor Paper storefront — a Next.js 16 e-commerce application with TypeScript, Tailwind CSS, and the Saleor GraphQL API. Contains 11 rules across 6 categories covering caching, PDP architecture, checkout components, UI patterns, and SEO.

Prerequisite: This skill depends on saleor-storefront for universal Saleor API knowledge (data model, permissions, checkout lifecycle, channels). Install it alongside this skill.

When to Apply

Reference these guidelines when:

• Working on product detail pages (PDP), variant selection, or filtering
• Modifying checkout flow or payment integration
• Editing GraphQL queries or regenerating types
• Debugging caching, stale content, or revalidation
• Creating UI components with design tokens
• Adding SEO metadata, JSON-LD, or OG images
• Writing tests or investigating Saleor API behavior
