Writing and executing C# scripts and macros against Power BI semantic models using Tabular Editor 2/3. Automatically invoke when the user mentions "C# script", "Tabular Editor script", "TOM scripting", "MacroActions.json", "XMLA", or asks to "automate model changes", "bulk update measures", "create calculation groups", "write a macro", "format DAX expressions", "manage model metadata".

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# C# Scripting for Tabular Editor Expert guidance for writing and executing C# scripts to manipulate Power BI semantic model metadata using Tabular Editor 2/3 CLI or the Tabular Editor IDE. ## When to Use This Skill Activate automatically when tasks involve: - Writing C# scripts for Tabular Editor - Bulk operations on model objects (measures, columns, tables) - Creating or modifying calculation groups - Managing model security (roles, RLS, OLS) - Formatting DAX expressions - Automating repetitive model changes - Querying model metadata via TOM API - Building interactive scripts with user input dialogs ## Critical - Every statement must end with `;` (semicolon required by C#) - Use double quotes `"` for strings and escape with `\` when needed - Use forward slashes `/` in DisplayFolder paths (auto-converted to `\`) - Always add `Info()` statements for debugging - script stops at error point - Test scripts on non-production models first - Changes are undoable with Ctrl+Z in the Tabular Editor UI ## C# Version Support | Environment | C# Version | Notes | |-------------|------------|-------| | **Tabular Editor 2** | Default compiler | Older C# syntax | | **Tabular Editor 3** | Roslyn |

What does the c-sharp-scripting skill do?
Writing and executing C# scripts and macros against Power BI semantic models using Tabular Editor 2/3. Automatically invoke when the user mentions "C# script", "Tabular Editor script", "TOM scripting", "MacroActions.json", "XMLA", or asks to "automate model changes", "bulk update measures", "create calculation groups", "write a macro", "format DAX expressions", "manage model metadata".
How do I install it?
Run `npx skills add data-goblin/power-bi-agentic-development --skill c-sharp-scripting --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From data-goblin/power-bi-agentic-development, a repository with 833 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
