powerbi-semantic-model-gotchas skillB

powerbi-semantic-model-gotchas is agent-read markdown (skill) from guust-franssens/tableau-to-powerbi-migration: Hard-won Power BI semantic-model gotchas - TMDL hand-authoring pitfalls that crash Desktop on open, the field-parameter sourceColumn bracket trap, the PLACEHOLDER measure-filter error, MCP/Desktop operational rules, offline model-integrity checks, and table-calculation patterns. Use before hand-authoring TMDL or DAX, and whenever a model validates clean but fails at open, refresh or render. Source-tool agnostic (Tableau, Qlik, Cognos to Power BI)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add guust-franssens/tableau-to-powerbi-migration/powerbi-semantic-model-gotchas@git:20260910.9808b82
Exact content
mdr add guust-franssens/tableau-to-powerbi-migration/powerbi-semantic-model-gotchas@sha256:39c7251d7341a5d2

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
