warehouse-and-schema-design

Guides agents through data warehouse and schema design. Use when defining fact and dimension models, keys, grain, normalization versus denormalization, serving-layer schema boundaries, and downstream-friendly table design.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by vaquarkhan on GitHub. Read the source before you install it.

Installation

Install the Warehouse And Schema Design AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/vaquarkhan/data-engineering-agent-skills/tree/main/skills/warehouse-and-schema-design
Enable the skill in any chat where you want it available.

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/vaquarkhan/data-engineering-agent-skills.git /tmp/data-engineering-agent-skills
mkdir -p .claude/skills
cp -r /tmp/data-engineering-agent-skills/skills/warehouse-and-schema-design .claude/skills/warehouse-and-schema-design

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Warehouse And Schema Design in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Warehouse And Schema Design on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Warehouse And Schema Design is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Warehouse And Schema Design

Overview

Use this skill when the primary challenge is how data should be modeled for reliable analytics consumption. It helps agents choose good grain, keys, relationships, and serving patterns so downstream work stays understandable and performant.

When to Use

designing marts, warehouse schemas, or curated serving tables
choosing fact and dimension boundaries
deciding grain, surrogate keys, or relationship strategy
balancing normalization and denormalization
restructuring analytics-facing datasets for usability

Do not reduce schema design to column naming alone. Good schema design is about behavior, meaning, and query ergonomics.

Workflow

Define the business grain first. Clarify:
- what one row represents
- what the primary analysis questions are
- how time and change should be represented
Choose the schema pattern intentionally. Common options:
- dimensional modeling
- data vault-oriented integration layers
- normalized serving models for operational analytics
- denormalized marts for common consumption patterns
Define keys and relationships. Include:
- business keys
- surrogate keys where needed
- slowly changing behavior
- null and unknown-member handling
Optimize for consumers, not just model purity. A perfect logical model that no analyst can use is not successful.
Validate compatibility with performance, governance, and metric use.

Common Rationalizations

Rationalization	Reality
"We can figure out grain later."	Grain mistakes spread quickly through metrics and dashboards.
"A wide table is always easier for analysts."	Very wide tables often hide conflicting grains and unclear semantics.
"Normalization is more correct, so we should always prefer it."	Correctness and usability both matter; serving models need intentional trade-offs.

Red Flags

row grain is undocumented
fact tables mix incompatible event types
keys are inconsistent across domains
schema choices are driven only by current dashboard convenience

Verification

Row grain and key strategy are explicit
Schema pattern matches the business use case
Consumer usability and performance have been considered
Change-over-time behavior is documented where relevant

Frequently asked questions

What does the Warehouse And Schema Design AI skill do?

Why use Warehouse And Schema Design on TypingMind?

Because you install it once and use it with any model. Warehouse And Schema Design is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Warehouse And Schema Design in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/vaquarkhan/data-engineering-agent-skills/tree/main/skills/warehouse-and-schema-design. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Warehouse And Schema Design?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Warehouse And Schema Design?

As many as you like. As long as a model supports skills, you can use Warehouse And Schema Design with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Warehouse And Schema Design AI skill free?

Yes. It is published on GitHub by vaquarkhan under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
