Shopify Liquid

This is a comprehensive Shopify theme development skill that enforces best practices through a search-then-validate workflow. Every response must search the Liquid documentation first, then validate generated code before returning it to you. It covers the full theme architecture (sections, blocks, snippets, layouts) with clear guidance on when to use each, plus it handles the gotchas like the 50-item loop limit and scope isolation in render tags. The schema validation is particularly useful since it checks your JSON against actual Shopify specs. If you're building themes and want guardrails that prevent common mistakes like using deprecated image filters or forgetting shopify_attributes on blocks, this keeps you honest.
