What problem does it solve? Migrating content into Wix requires re-deriving fragile API request shapes, retry logic, batching limits, and verification rules for every project, which leads to duplicated bugs like silent pagination loss and invalid bulk payloads. This Skill centralizes the verified Wix write surface and shared execution runtime so migration codegen never re-derives Wix plumbing. ## Core Features & Use Cases - Verified write primitives: Request builders and executors for Wix Stores, Blog, CMS, Contacts, Members, and Media, each marked VERIFIED or UNVERIFIED based on live contract testing. - Shared execution runtime: Common modules for retries, throttling, checkpointing, NDJSON record-stream batching, audit logging, and crosswalk state that generated migrations consume instead of re-implementing. - Machine-readable domain knowledge: A validated domains/ knowledge base with entity suitability, reliability flags, field contracts, and source-alias resolution queryable via CLI scripts. - Use Case: When generating a WooCommerce-to-Wix migration, codegen vendors lib/wix-writers.js and lib/ndjson.js, batches products with readBatchesByLimits against the five simultaneous bulk caps, and resolves target entities through scripts/domain-knowledge.js instead of hardcoding Wix API details. ## Quick Start Ask the AI to look up the Wix target suitability and verified write contract for a source entity such as a WooCommerce product using the domain knowledge scripts.
