This is your go-to for building and validating Salesforce OmniStudio Data Mappers (the things formerly called DataRaptors). It handles all four types: Extract for reads, Turbo Extract for high-volume queries, Transform for in-memory reshaping, and Load for writes. The skill scores your configurations across five categories with a 100-point system and catches common mistakes like missing FLS checks, unbounded queries, and hardcoded IDs before deployment. It's opinionated about naming conventions and will stop you if you're about to generate something that'll blow up in production. Works in the OmniStudio stack order, so run the analyze skill first to understand dependencies, then build your Data Mappers before touching Integration Procedures or OmniScripts.
