Power BI semantic modelling assistant for building optimised data models. Use when working with Power BI semantic models, creating measures, designing star schemas, configuring relationships, implementing RLS, or optimising model performance. Triggers on queries about DAX calculations, table relationships, dimension/fact table design, naming conventions, model documentation, cardinality, cross-filter direction, calculation groups, and data model best practices. Always connects to the active…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Power BI Semantic Modelling Guide users in building optimised, well-documented Power BI semantic models following Microsoft best practices. ## When to Use This Skill Use this skill when users ask about: - Creating or optimising Power BI semantic models - Designing star schemas (dimension/fact tables) - Writing DAX measures or calculated columns - Configuring table relationships (cardinality, cross-filter) - Implementing row-level security (RLS) - Naming conventions for tables, columns, measures - Adding descriptions and documentation to models - Performance tuning and optimisation - Calculation groups and field parameters - Model validation and best practice checks **Trigger phrases:** "create a measure", "add relationship", "star schema", "optimise model", "DAX formula", "RLS", "naming convention", "model documentation", "cardinality", "cross-filter" ## Prerequisites ### Required Tools - **Power BI Modelling MCP Server**: Required for connecting to and modifying semantic models - Enables: connection_operations, table_operations, measure_operations, relationship_operations, etc. - Must be configured and running to interact with models ### Optional Dependencies …

How to install
mdr add marielynneblock/arcanum-artifex/powerbi-modelling@sha256:064b034f1dbc31bfThe line at the top of this page pins the label v0.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
