Refreshing Semantic Models
Trigger, monitor, validate, and troubleshoot semantic model refreshes via the Power BI Enhanced Refresh REST API and Fabric CLI.
Core Concepts
A semantic model refresh reloads data from upstream sources and/or recalculates dependent objects (calculated columns, calculated tables, measures). The scope can be the entire model, specific tables, or individual partitions.
Six refresh types are available via the REST API; a seventh (add) is TMSL-only:
| Type | Reloads Data | Recalculates | Primary Use Case | API |
|---|---|---|---|---|
full |
Yes | Yes | Complete reload from scratch | REST |
automatic |
Conditional | Conditional | Smart refresh; process only if needed | REST |
dataOnly |
Yes | No* | Reload data; clear dependents | REST |
calculate |
No | Yes | Recalculate without reloading data | REST |
clearValues |
No | No | Empty data from objects | REST |
defragment |
No | No | Clean up column dictionaries | REST |
add |
Append | Yes | Append rows to a partition | TMSL |

create-pbi-report
Step-by-step workflow for creating complete Power BI reports from scratch using pbir CLI. Covers model discovery, report creation, page layout, theme setup, visual placement, field binding, filtering, formatting, validation, and publishing. Automatically invoke when the user asks to "create a new report", "build a report from scratch", "make a dashboard", "set up a report with KPIs", "create an executive dashboard", "add pages and visuals to a new report".
16tmdl
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.
16pbi-report-design
Power BI report design principles, layout guidance, and formatting best practices. Automatically invoke when the user asks about "report layout", "design best practices", "visual hierarchy", "3-30-300 rule", "KPI card design", "page layout", "accessibility in reports", "visual spacing", "report canvas", "card design patterns", "table formatting", "matrix formatting", or mentions report design principles.
15pbir-format
Format reference for Power BI Enhanced Report (PBIR) JSON schemas and patterns. Automatically invoke when the user asks about PBIR JSON structure, visual.json properties, PBIR expressions, objects vs visualContainerObjects, theme inheritance, conditional formatting patterns, extension measures, bookmarks, field references, filter formatting, query roles, PBIR page structure, report wallpaper, or any PBIR metadata format question.
15pbip
Expert guidance for the Power BI Project (PBIP) file format; project structure, cross-cutting operations (renames, forking), and PBIX extraction/conversion. Automatically invoke when the user mentions PBIP, PBIX, .pbip/.pbism/.platform files, or asks about "PBIP project structure", "PBIP vs PBIX", "thin report vs thick report", "rename a table", "cascade rename", "fork a PBIP project", "convert pbix to pbip", "extract pbix", "what files are in a PBIP", "PBIP encoding", "definition.pbir", or discusses project-level file structure and post-rename verification.
14modifying-theme-json
Design, enforce, audit, and validate Power BI report themes. This skill MUST be invoked when a report uses the default or built-in theme, has a minimal custom theme (few or no visualStyles), or has accumulated many visual-level formatting overrides (objects/visualContainerObjects in visual.json); these are signs the theme needs attention. Also automatically invoke when the user asks to "create a theme", "design a theme", "enforce theme compliance", "audit theme adherence", "push formatting to theme", "clear visual overrides", "standardize report formatting", "update theme colors", "change theme typography", "set theme text classes", "validate a theme", "add visual-type overrides to the theme", "copy a theme", "download a theme", "apply a template", or mentions theme design, enforcement, compliance, or visual formatting inconsistency.
