FastStore SDK State Management

When this skill applies

Use this skill when:

• You are building any interactive ecommerce feature that involves the shopping cart, user session, product search/filtering, or analytics tracking.
• You need to add, remove, or update cart items.
• You need to read or change session data (currency, locale, sales channel, postal code).
• You need to manage faceted search state (sort order, selected facets, pagination).
• You are working with @faststore/sdk hooks (useCart, useSession, useSearch).

Do not use this skill for:

• Visual-only changes — use the faststore-theming skill.
• Replacing or customizing native components — use the faststore-overrides skill.
• Extending the GraphQL schema or fetching custom data — use the faststore-data-fetching skill.
