What problem does it solve? Power BI's default .pbix format is a binary zip that cannot be diffed, merged, or reviewed in git, making it impossible to track who changed a DAX measure or why. This Skill guides teams through adopting the Power BI Project (PBIP) format so semantic models and reports become reviewable plain-text code. ## Core Features & Use Cases - PBIP Adoption & Assessment: Run governed, read-only intake of an existing PBIP project with seshat adopt-pbip assess, then scaffold an adoption record only after explicitly accepting the assessment digest. - Commit vs. Ignore Rules: Apply Microsoft's official .gitignore baseline so TMDL model definitions are tracked while localSettings.json and cache.abf stay out of version control. - Windows & Diff Troubleshooting: Resolve 260-character path limits, CRLF line-ending noise, UTF-8 BOM corruption, and stale Power BI Desktop sessions that hide external edits. - Use Case: A teammate opens a pull request changing the Gross Margin measure. Because the measure lives in TMDL text, you review it like code—checking for DIVIDE() usage, duplicated logic, and bidirectional relationships—before merging. ## Quick Start Ask the assistant to assess an existing Power BI Project directory for git adoption and explain which files should be committed or ignored.
