npx skills add sickn33/antigravity-awesome-skills --skill shopify-development
Use this skill when the user asks about:
IF user wants to integrate external services OR build merchant tools OR charge for features:
→ Build an App (see references/app-development.md)
IF user wants to customize checkout OR add admin UI OR create POS actions OR implement discount rules:
→ Build an Extension (see references/extensions.md)
IF user wants to customize storefront design OR modify product/collection pages:
→ Build a Theme (see references/themes.md)
IF user needs both backend logic AND storefront UI: → Build App + Theme Extension combination
Install CLI:
Create and run app:
Generate extension:
Theme development:
Configure in shopify.app.toml:
Common scopes:
read_products, write_products - Product catalog accessread_orders, write_orders - Order managementread_customers, write_customers - Customer dataread_inventory, write_inventory - Stock levelsread_fulfillments, write_fulfillments - Order fulfillmentVariables example:
In shopify.app.toml:
pageInfo.endCursorimg_url filterIF you see rate limit errors:
→ Implement exponential backoff retry logic
→ Switch to bulk operations for large datasets
→ Monitor X-Shopify-Shop-Api-Call-Limit header
IF authentication fails: → Verify the access token is still valid → Check that all required scopes were granted → Ensure OAuth flow completed successfully
IF extension is not appearing:
→ Verify the extension target is correct
→ Check that extension is published via shopify app deploy
→ Confirm the app is installed on the test store
IF webhook is not receiving events: → Verify the webhook URL is publicly accessible → Check HMAC signature validation logic → Review webhook logs in Partner Dashboard
IF GraphQL query fails: → Validate query against schema (use GraphiQL explorer) → Check for deprecated fields in error message → Verify you have required access scopes
