Skill UI

Provides comprehensive guidance for managing the entire lifecycle of tabular data models (e.g., Power BI, Analysis Services). This skill covers design (star schema, relationships), building (measures, calculated groups), refreshing (incremental refresh), and auditing (performance, best practices). It enforces a systematic 'tool cascade,' routing operations through the dedicated CLI first, then to model servers, and finally to TMDL authoring, ensuring optimal model quality and adherence to industry best practices.

Calculates statistical power and required sample sizes for study planning. It supports both closed-form methods (for standard tests like t-tests, ANOVA) and simulation-based methods (for complex models like mixed models or survival analysis). Use this skill to determine the minimum detectable effect (MDE) or justify sample sizes for grants and IRB protocols before data collection.
