What problem does it solve? Shopify development questions often get answered from memory, producing unverified claims about Liquid behavior, API limits, or platform constraints. This Skill enforces an evidence standard so every Shopify conclusion is grounded in MCP documentation, repository evidence, or explicit unknowns. ## Core Features & Use Cases - MCP-First Verification: Requires checking Shopify MCP documentation before making claims about Liquid objects, API fields, schema attributes, or checkout behavior. - Vault Routing: Defines a cheapest-first loading order across the Shopify module, project brains, personal preferences, and client-specific vault folders. - Complexity Assessment: Outputs a model recommendation with tier, fallback, and escalation triggers before any implementation begins. - Use Case: When asked whether a Liquid filter supports a specific argument, the agent verifies via Shopify MCP docs, cites the evidence, and states a complexity tier before proposing code changes. ## Quick Start Ask the agent to answer a Shopify platform question or plan a Shopify implementation, and it will verify claims through MCP documentation before responding.
