  • 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 kemiljk on GitHub. Read the source before you install it.

Installation

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

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/kemiljk/skills/tree/main/skills/subtractive-design
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

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/kemiljk/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/skills/subtractive-design .claude/skills/subtractive-design
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Subtractive 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 Subtractive 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 Subtractive 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.

Subtractive Design

Design is subtractive. Absence creates hierarchy, calm, and focus. Adding feels productive; removing is usually the harder and better move.

Defaults

  1. Require a demonstrable purpose for every element, token, and interaction.
  2. Prefer fewer decisions for the user at each step.
  3. Use space, silence, and restraint as active design materials.
  4. Hide necessary complexity rather than celebrating it.
  5. Cut anything that exists only because it was easy to generate.

Prefer / Reject

PreferReject
Clear primary actionEqual-weight button forests
Progressive disclosureShowing every option up front
Shared tokens and patternsOne-off flourishes per screen
Defaults that remove setupPreference panels for undecided design
Calm empty spaceFilling space because it is empty

Process

  1. List what the screen must accomplish.
  2. Mark every element that does not serve that list.
  3. Remove or demote the marked set.
  4. Recheck whether the remaining pieces still need labels, chrome, or motion.
  5. Stop when further removal would hide a needed decision or affordance.

Review checklist

  • Can any control be removed without harming the task?
  • Is there a single clear primary action?
  • Are secondary actions visually secondary?
  • Is any copy repeating what the UI already shows?
  • Are decorative layers earning their keep?
  • Would a quieter version communicate the same intent faster?

Frequently asked questions

What does the Subtractive Design AI skill do?

Simplify noisy interfaces and evaluate whether proposed UI additions serve a concrete user need.

Why use Subtractive Design on TypingMind?

Because you install it once and use it with any model. Subtractive 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 Subtractive Design in TypingMind?

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

Which AI models can use Subtractive 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 Subtractive Design?

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

Is the Subtractive Design AI skill free?

Yes. It is published on GitHub by kemiljk 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.
