Skill: Semantic Schema Mapping Planning

Follow this structured process and procedures for analyzing source-to-target data relationships and creating a high-fidelity Mapping Plan (also known as a Mapping Manifesto). This process is platform-agnostic and should be used before generating any target-specific pipeline code. When this skill is loaded, you MUST use this plan and replace the existing generic plan.

When to Use

Use this skill when:

• You need to map schemas between a source dataset/database and a target destination database/warehouse.
• You are initiating an ETL, ELT, or data integration task.
• You need to identify schema gaps, data type conflicts, or aggregation requirements.
