# Build Checklist Before implementation, confirm that .ai/STORE-BRIEF.md contains enough detail for: - Repo mode and current repo responsibilities. - Backend stack and database choice. - Frontend stack and rendering assumptions. - Storefront pages and flows. - Auth model and cart model. - Admin modules and staff roles. - Catalog entities and filtering model. - Order or lead flow. - Integrations and external dependencies. - Visual direction and asset status. - AGENTS.md plan. If one of these is materially missing, ask a focused follow-up question or record the implementation assumption before building.
