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.

9# Migrating a dbt Core Project to Fusion
10
11dbt Fusion is dbt Labs' next-generation engine for parsing, compiling, and running dbt projects. This skill guides you through migrating an existing dbt Core project to be compatible with the Fusion engine.
12
13## Goals
14
151. Make a pre-existing dbt project compatible with dbt Fusion, so it can parse and compile successfully on the Fusion engine.
162. Preserve existing functionality as much as possible.
173. Flag when the dbt project is using functionality that's not yet supported in Fusion, and ask users so they can choose whether to wait for feature support or remove use of unsupported features.

20## Migrating to the new authoring layer and the dbt Fusion engine
21
22if a user says "migrate my dbt project to the new authoring layer" or "make my dbt project compatible with the Fusion engine" do the following steps and the migration is only successfully completed once dbtf compile finishes with 0 errors. Create a changes_made.md file documenting and summarizing all of the code changes made in the user's dbt project, including what the error was, the fix applied, and a summary of why the fix was chosen.
23
24Before you begin, please read and understand the resources section below. Only apply fixes that are described in the provided Resources. Do not attempt undocumented fixes—if a solution isn't in these resources, inform the user and stop.
25
261. Run dbtf debug in the terminal to check their data platform connections. Proceed to step 2 if there are no errors. If there are errors, please summarize the error succinctly so the user knows how to debug on their own.
272. Run dbtf parse --show-all-deprecations in the terminal to check for compatibility errors in their current project. Summarize the log output by specifying how many errors were found and group the errors in a way that's easily understandable.

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.

≈50
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
4,350
on trigger
The instruction body and 7 supporting files, read only when the skill fires.
2.2%
of a 200k window
Ten skills this size would take about 22% of the window before you open a file.
050k100k150k200k context window

4.4k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. 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

8 files, 17.6 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md6.3 kB
  • manual_fixes/custom_configuration.md3.5 kB
  • manual_fixes/dynamic_sql.md0.7 kB
  • manual_fixes/iceberg_tables.md2.3 kB
  • manual_fixes/misspelled_config_keys.md1.4 kB
  • manual_fixes/package_incompatibility.md2.3 kB
  • manual_fixes/README.md0.5 kB
  • manual_fixes/sources_without_tables.md0.6 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 8 files you can review in full before installing. The Apache-2.0 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.

# Migrating a dbt Core Project to Fusion · 4.4k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/migrating-a-dbt-core-project-to-fusion/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/migrating-a-dbt-core-project-to-fusion" ] && { [ ! -e .claude/skills/migrating-a-dbt-core-project-to-fusion ] || { mv .claude/skills/migrating-a-dbt-core-project-to-fusion "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/migrating-a-dbt-core-project-to-fusion" .claude/skills/ && echo "Installed .claude/skills/migrating-a-dbt-core-project-to-fusion"

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/migrating-a-dbt-core-project-to-fusion/ 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/migrating-a-dbt-core-project-to-fusion/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/migrating-a-dbt-core-project-to-fusion" ] && { [ ! -e ~/.claude/skills/migrating-a-dbt-core-project-to-fusion ] || { mv ~/.claude/skills/migrating-a-dbt-core-project-to-fusion "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/migrating-a-dbt-core-project-to-fusion" ~/.claude/skills/ && echo "Installed ~/.claude/skills/migrating-a-dbt-core-project-to-fusion" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/migrating-a-dbt-core-project-to-fusion/ 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 migrating-dbt-core-to-fusion in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, migrating-a-dbt-core-project-to-fusion.

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.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
