Direct TMDL file authoring and BIM-to-TMDL conversion for semantic models in PBIP projects. Automatically invoke when the user asks to "edit TMDL", "add a measure in TMDL", "TMDL syntax", "fix formatString", "fix summarizeBy", "TMDL indentation", "convert BIM to TMDL", "add a column description", "create a calculated column in TMDL", or mentions .tmdl file editing or BIM-to-TMDL migration.
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
# TMDL Authoring Expert guidance for authoring and editing TMDL (Tabular Model Definition Language) files directly in PBIP projects. > **This skill is a last resort.** Direct TMDL file editing lacks the validation, atomicity, and DAX query capabilities of the Tabular Editor CLI, Power BI MCP server, or the `connect-pbid` skill (TOM via PowerShell). Use those tools when available. TMDL editing is appropriate when: > > - Working with PBIP files in a Git repo without Power BI Desktop open > - No Tabular Editor CLI or MCP server is installed > - Making quick text-level fixes (descriptions, format strings, display folders) where a full tool chain is overkill > > Direct TMDL editing does not validate DAX syntax, check referential integrity, or verify that property values are valid. Errors will only surface when the model is next loaded in Power BI Desktop or deployed via XMLA. Use the **`pbip-validator`** agent to check TMDL files for syntax issues, indentation errors, and referential integrity before opening in PBI Desktop. ## Validation: tmdl-validate v0.2.0 `tmdl-validate` supports two modes: ```bash …

How to install
mdr add santoshkanthety/powerbi-agent/powerbi-tmdl@sha256:2ff3e15fdabad4a1The 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.
