Writes, explains, debugs, and optimizes BI calculations - Power BI / Fabric DAX measures and calculated columns, Tableau calculated fields (FIXED/INCLUDE/EXCLUDE LOD expressions, table calculations), and Looker LookML measures, dimensions, and derived tables. Use it whenever the request involves DAX, CALCULATE, a Power BI measure, a Tableau calc or LOD, LookML, or a business metric such as YoY, YTD, rolling 12 months, running total, percent of total, distinct customers, ranking, new vs…
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
# BI Measure Builder Most wrong BI numbers are not syntax errors. They are the right formula evaluated in the wrong context. Work context-first, and prove every measure against numbers computed independently. ## Workflow 1. **Pin down the model before writing anything.** Get (or state as an explicit assumption): the fact table and its grain (one row per order line? per snapshot?), dimension tables, relationship keys and direction, and the date table. Ask only for what changes the formula; otherwise state the assumption and proceed. Why: the same YoY formula is right on a star schema and wrong on a flat table with a text date. 2. **Name the platform and version features.** DAX: classic vs calendar-based time intelligence (preview), marked date table or not. Tableau: live vs extract, context filters in use. Looker: dialect (window-function support, `period_over_period` support). 3. **State the evaluation context in one or two sentences** for a typical visual cell *and* for the grand total. Example: "Row = Month; filters = Region slicer; total = all months in the slicer range, recomputed, not summed." Why: this is where most bugs live, and saying it forces the check. …

How to install
mdr add onewave-ai/claude-skills/bi-measure-builder@sha256:0ae09bda75ec971fThe line at the top of this page pins the label git:20260923.ebdb76d, 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.
