What problem does it solve? Migrating a site to Wix requires deciding what every source entity and field becomes on the Wix side, and hand-authoring those mappings is slow, inconsistent, and prone to silently dropping data. This Skill produces machine-readable mapping artifacts and human review summaries so every column is either mapped or explicitly skipped. ## Core Features & Use Cases - Deterministic mapping resolution: Runs scripts/resolve-mapping.js to join discovered CSV headers, vendor overlays, and the Wix target spec, producing mapping-resolution.json and an explicit residue queue of unmapped columns, unsupported targets, and unfilled required fields. - Faithfulness ledger: Records lossy transformations, skipped entities, hierarchical-to-flat taxonomy drops, and unverified Wix targets in mapping-gaps.json before execution, so users are warned before consent. - Review workflow: Generates mapping-plan.md and mapping-summary.md, then pauses at a mapping review checkpoint before downstream setup and code generation. - Use Case: After discovering a Shopify CSV export, run the resolver to auto-map known columns, then decide only the residue entries and produce a reviewable plan mapping products, categories, and orders to Wix Stores and eCommerce entities. ## Quick Start Ask the assistant to run the rp-mapper skill on the discovered source schema in migrations/<project> to produce the mapping plan and review summary.
