From the source SKILL.md

Activate this skill before any CSV load — Data Loader, dataloader.io, Workbench, or a custom Bulk API V2 client — to lock down the column-to-field binding before a single row is sent. The cost of a wrong mapping is rarely a hard error: it is a "successful" job that silently dropped fields because of FLS, header case mismatches, polymorphic lookups missing a type prefix, or picklist labels submitted where API names were required.
