What problem does it solve? Turning approved migration schemas and mapping plans into runnable import code is error-prone: hand-written Wix request shapes, slug sanitizing, bulk batching, and dedupe logic repeatedly ship bugs that only surface at execution time. This Skill generates the project-specific code layer from machine-readable artifacts so the migration runs through verified shared runtime primitives instead of ad-hoc code. ## Core Features & Use Cases - Source reader generation: Produces platform-agnostic extraction entrypoints that vendor the matching source adapter's transport (HTTP or CSV file readers) and write durable NDJSON extract files to disk. - Transform and write-spec generation: Emits thin transforms over the shared Wix build layer and per-entity write specs that call the verified rp-target-wix runtime, including Catalog V3 product shapes, bulk batching by endpoint limits, and crosswalk-based idempotent dedupe. - Execution artifacts and safety gates: Generates runnable setup/extract/import entrypoints, execution manifests, dry-run support, notification-mute preflight, and a mandatory code-safety review artifact when SAFE_MODE or DRY_RUN is enabled. - Use Case: After approving a mapping plan for a WordPress-to-Wix store migration, run this Skill to produce the reader, transforms, and import runner that rp-execute-import will execute, complete with a sample-preview gate before any live write. ## Quick Start Generate the migration import code for the active project from its source-schema.json, mapping-plan.json, and setup-plan.json artifacts.
