semantic-model-disambiguation

semantic-model-disambiguation is a skill for Claude Code, Codex from fabioc-aloha/Alex_Skill_Mall. It costs 37 tokens per session (8,252 once invoked), scanned A, original, MIT.

A Power BI workflow for applying approved fixes to a semantic model, such as clearer column descriptions, hidden columns, and instructions for AI tools.

In plain words
What is it for?
Use it after reviewing an overlap analysis to apply approved changes to a live Power BI model.
Why use it?
It reduces confusion when Copilot or Fabric data agents choose between columns with similar meanings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

semantic-model-disambiguation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Semantic Disambiguation

Read a reviewed disambiguation Excel workbook, extract approved rows, and apply changes to the live semantic model via MCP. This skill handles the execution phase — it assumes the semantic-overlap-detection skill has already produced the analysis and review Excel, and a domain expert has reviewed it.

Prerequisite: The semantic-overlap-detection skill must have been run first to produce output/disambiguation_analysis.json and output/disambiguation_results.xlsx in the plugin directory, and the domain expert must have set Review Status on all rows.

When to Use

  • A domain expert has reviewed the disambiguation Excel and set Review Status to Approved/Rejected/Needs Discussion
  • You need to apply approved column descriptions to the live model
  • You need to hide excluded columns from the AI data schema
  • You need to generate AI instructions text from approved business rules

Procedure

Step 1: Establish MCP Connection

MCP tool naming: This skill references tools by their VS Code MCP integration names (mcp_powerbi-modeling-mcp_*). In other environments (Agency CLI, Claude Code), find the equivalent Power BI Modeling MCP server tools — the operations and parameters are the same, only the tool name prefix may differ.

The apply phase updates the live model via MCP tools. If the MCP connection has expired (e.g., the user reviewed the Excel in a different session), re-establish it:

  1. Connect via mcp_powerbi-modeling-mcp_connection_operations:

    • Fabric: ConnectFabric with workspace and dataset names
    • Desktop: Connect with port number
  2. Verify connection by listing tables via mcp_powerbi-modeling-mcp_table_operations (operation: List).

Step 2: Read the Reviewed Excel

Use openpyxl (or the apply script's read_approved_items() function) to parse the Excel:

from scripts.apply_disambiguation_excel import read_approved_items
from pathlib import Path

# Plugin output directory
output_dir = Path(__file__).resolve().parent.parent.parent / "output"
descriptions, rules, exclusions = read_approved_items(output_dir / "disambiguation_results.xlsx")

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
