What problem does it solve? Raw Excel columns from heterogeneous toll providers arrive in inconsistent formats, and this Skill guides the implementation of the Peajes transformation engine that adapts them into the standardized Pasada-Columns model across Angular preview and Supabase persistence. ## Core Features & Use Cases - Strategy Registry: Maps stable algorithm codes (BORRAR_ESPACIOS, FORMATEAR_FECHA_HORA, CALCULAR_IMPORTE_NETO, and more) to atomic TransformStrategy implementations, rejecting unknown codes per RN-20. - Pipeline Builder: Expands combined algorithms like NORMALIZAR_PATENTE into ordered atomic steps and validates duplicate orden values per RN-18. - Provider Adapters: Normalizes provider-specific headers (Demo today, extensible via IProviderAdapter) with compatibility detection before execution. - Use Case: When wiring Paso 3 transformaciones to preview how a provider's FECHA, HORA, DOMINIO, and TARIFA columns become FECHA_HORA, PATENTE_ID, and IMPORTE_NETO, use this Skill to build and validate the pipeline through PeajesMotorTransformacionService. ## Quick Start Ask the agent to build and validate a transformation pipeline for the Demo provider columns using PeajesMotorTransformacionService and show the Paso 3 preview output.
