Analyze a semantic model (via MCP or TMDL) to find columns whose value domains overlap, classify ambiguity types, generate proposed descriptions/rules/exclusions, and produce a review Excel for domain experts. Use when a semantic model has columns whose values overlap across tables or hierarchies, when Copilot picks the wrong column for ambiguous queries, when preparing a model for Prep data for AI, or when auditing a model for attribute collisions before connecting a data agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Semantic Overlap Detection Analyze a semantic model (via MCP connection or TMDL export) to find columns whose value domains overlap, classify ambiguity types, generate proposed fixes, and produce a review Excel workbook for domain expert review. This skill covers the full analysis pipeline through Excel generation and async handoff. **Next step after this skill**: Once the domain expert has reviewed the Excel, use the **semantic-disambiguation** skill to apply approved changes to the live model. ## When to Use - A semantic model has multiple columns that could plausibly match the same natural-language query - A Fabric data agent or Copilot is silently picking the wrong column - You need to prepare a model for the "Prep data for AI" workflow - You want to audit a TMDL export for disambiguation gaps before connecting a data agent ## Procedure ### Phase 0: Read Model Metadata via MCP (preferred) or TMDL files …

How to install
mdr add fabioc-aloha/alex_skill_mall/semantic-overlap-detection@sha256:5ef274db189f0b70The line at the top of this page pins the label git:20260728.80a7ab6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
