Author, validate, and test Power Query M expressions in semantic model partitions.

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 Query for Semantic Models
Author, validate, and test Power Query M expressions in semantic model import partitions. Covers writing correct M code, preserving query folding, validating expressions, and testing them by executing against real data sources.
## Partition Expressions
Each import table in a semantic model has a partition with an M expression defining what data gets loaded during refresh. The expression typically connects to a data source, navigates to a table/view, and applies transformations.
### Structure of a Partition Expression
```
let
Source = Sql.Database(#"SqlEndpoint", #"Database"),
Data = Source{[Schema="dbo", Item="Orders"]}[Data],
#"Removed Columns" = Table.RemoveColumns(Data, {"InternalId"}),
#"Changed Type" = Table.TransformColumnTypes(#"Removed Columns", {{"Amount", Currency.Type}})
in
#"Changed Type"
```
Key elements:
- **Parameters**: `#"SqlEndpoint"`, `#"Database"` are shared M parameters defined at the model level
- **Navigation**: `Source{[Schema="dbo", Item="Orders"]}[Data]` navigates to a specific table
- **Steps**: Each step is a named variable in the `let...in` chain

How to install
mdr add santoshkanthety/powerbi-agent/powerbi-power-query@sha256:5814f1ad09e2b393The line at the top of this page pins the label git:20260808.22d6d33, 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.
