power-query

power-query is a skill for Claude Code, Codex from data-goblin/power-bi-agentic-development. It costs 79 tokens per session (2,113 once invoked), scanned A, original, GPL-3.0.

A tool for writing, validating, and testing Power Query M expressions, the formulas used to prepare and transform data in Microsoft data models. It can work with model partitions, which are separate portions of a dataset.

In plain words
What is it for?
Creating or fixing M expressions, testing partition logic, previewing partition data, investigating query folding, and debugging Power Query work.
Why use it?
It helps diagnose errors in data-transformation formulas and investigate whether queries can be pushed back to the data source efficiently.

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

power-query scanned grade A with 1 finding 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 5d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (examples/execute_m.py, examples/preview_partition.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
