What it does

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.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

6# PBIR Format Reference

8Skill that teaches Claude about the Power BI Enhanced Report (PBIR) JSON format to read and use it. Doesn't support legacy report.json or layout report metadata. To convert from legacy to PBIR format, users have to open and save their reports in Power BI Desktop.

10Follow within reason the [mental model](./important/MENTAL-MODEL.md) when working with reports.

12**Hard rule:** Treat PBIR JSON as an implementation detail. Read it when schema context is

13useful, but make every report, visual, page, bookmark, filter, mobile-layout, and theme change

14through pbir. Never hand-edit, text-replace, or script writes to report JSON. If pbir cannot

15express a requested mutation, stop and report the capability gap instead of inventing a raw-JSON

16fallback.

18## General, critical guidance

20- **Check examples:** Check [examples](./examples/) for a valid report

21- **Take a backup:** Make a copy of the report before modifying it

22- **PBIX vs PBIP vs PBIR:** Work on a local .Report folder in PBIR format. Use Power BI

23 Desktop or pbir report convert for supported conversions; do not unzip, rezip, or patch PBIX

24 internals. Do not work directly on PBIT files.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈120

always loaded

The name and description, so the model knows the skill exists and when to reach for it.

278,455

on trigger

The instruction body and 108 supporting files, read only when the skill fires.

1.4×

a 200k window

It does not fit in the window: loaded whole, it would need more room than the model has.

050k100k150k200k context window

278.6k tokens, estimated from the bundle at four bytes to the token — more than the whole window, so it cannot all be held at once: the model reads SKILL.md when the skill fires and the other files only as the instructions call for them. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for

Writes filesnot declared

Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

The download carries 109 of the 123 files in its source folder; the list here names 109 files, 1114.3 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in. The other 14 are not in the download, nor is 1 file of a type a skill download does not carry — listed after these, with why.

Not in the download

Too deep is past six folders and not carried is a type a skill download does not hold. Marked read: its SKILL.md or scripts name the file, so without it the skill works only in part. Take them from its source.

What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the download is 109 files — not the whole of its source: 15 files are left out, and the skill reads 14 of them. They are listed under the files, with why. The GPL-3.0 licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

npx mcprush@latest skill add data-goblin/pbir-format-reference

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/pbir-format-reference/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/pbir-format-reference/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/pbir-format-reference" ] && { [ ! -e ~/.claude/skills/pbir-format-reference ] || { mv ~/.claude/skills/pbir-format-reference "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/pbir-format-reference" ~/.claude/skills/ && echo "Installed ~/.claude/skills/pbir-format-reference" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/pbir-format-reference/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as pbir-format in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, pbir-format-reference. Not in this download: 15 files of its source, 14 of them read by its SKILL.md or scripts (the full list, and why). Take them from its source.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.
