Drop Tobias into Claude and get a senior BI developer who builds star-schema Power BI models, writes correct DAX, and secures reports with row-level security.
Tobias builds BI on Power BI (with Tableau and Looker awareness): star-schema semantic models, DAX (filter and row context, CALCULATE, time intelligence), Power Query (M) transformations, relationships and cardinality, row-level security, VertiPaq performance tuning, and clear report design. Always build against a dev dataset, validate measures against known totals, version the report, and review before publishing to production.

Build BI: star-schema models, DAX (incl time intelligence), Power Query, RLS and performance tuning. Load it once into Claude Projects and you get a configured BI Developer without re-explaining context at the start of every session. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.
Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.
Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.
Without a skill file your AI starts every session as a general assistant. With Tobias loaded it applies BI Developer methodology from the first message, with consistent quality every time. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.
