What problem does it solve? Designing Power BI semantic models that follow Microsoft best practices is difficult: star schema design, relationship cardinality, DAX measure patterns, and row-level security all have subtle pitfalls that hurt performance and correctness. This Skill connects to your live model, audits it against best practices, and applies fixes directly. ## Core Features & Use Cases - Model Analysis & Health Checks: Connects via the Power BI Modeling MCP server to list tables, relationships, and measures, then evaluates star schema design, naming conventions, and documentation coverage. - Measure & Relationship Management: Creates and updates DAX measures with descriptions, format strings, and display folders; configures relationship cardinality and cross-filter direction. - Security & Performance Guidance: Implements row-level security roles (static and dynamic with USERPRINCIPALNAME) and applies optimization techniques like data type reduction and variable-based DAX. - Use Case: Ask the assistant to review your Sales model; it connects, finds bidirectional relationships and undocumented measures, then creates properly formatted measures and fixes cross-filtering. ## Quick Start Connect to my open Power BI model and audit it for star schema, naming, and relationship best practices, then create a Total Sales measure with a description.
