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 Dragoon0x on GitHub. Read the source before you install it.

Installation

Install the Design Spec Writing 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/Dragoon0x/everything-design-taste/tree/main/skills/design-spec-writing
Enable the skill in any chat where you want it available.

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/Dragoon0x/everything-design-taste.git /tmp/everything-design-taste
mkdir -p .claude/skills
cp -r /tmp/everything-design-taste/skills/design-spec-writing .claude/skills/design-spec-writing

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

Use it in TypingMind

Enable Design Spec Writing 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 Design Spec Writing 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 Design Spec Writing 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.

Design Spec Writing

Why Most Specs Fail

Engineers don't read specs because specs are usually:

Too long (nobody reads 40 pages)
Too vague ("the button should feel responsive")
Out of date (the design changed but the spec didn't)
Redundant with the Figma file (so why bother?)

What a Good Spec Contains

1. Overview (1 paragraph)

What this feature is, who it's for, and why it exists. Link to the product brief.

2. User Flow (visual)

Flowchart or numbered steps showing the complete path. Include error paths and edge cases.

3. Screen-by-Screen Spec

For each screen:


## [Screen Name]

**Entry point:** How does the user get here?
**Primary action:** What's the main thing they do?
**Exit points:** Where can they go from here?

### States
- Default: [description + link to Figma frame]
- Loading: [description]
- Empty: [description]
- Error: [description + error messages]
- Success: [description]

### Interactions
- [Element]: [Behavior on click/hover/focus]
- [Element]: [Behavior on click/hover/focus]

### Content
- [Field]: [Character limits, formatting rules]
- [Field]: [Validation rules, error messages]

### Edge Cases
- What happens when [unlikely but possible scenario]?
- What if the user [does something unexpected]?

4. Component Inventory

List of design system components used and any new components introduced.

5. Responsive Behavior

How the layout adapts. Not "it stacks on mobile." Specific decisions: what changes, what hides, what reorders.

6. Animation Spec


[Element]: [Trigger] → [Property] from [start] to [end]
Duration: [Xms], Easing: [curve], Delay: [Xms]

7. Acceptance Criteria

Testable statements:

User can [action] and sees [result]
When [condition], the system [behavior]
Error state shows when [trigger]

Writing Style

Use numbered steps, not paragraphs
Link to specific Figma frames, not "see designs"
Include actual copy, not "TBD"
State exact values (16px, not "some padding")
Update the spec when the design changes

Frequently asked questions

What does the Design Spec Writing AI skill do?

Writing design specifications that engineers actually read, reference, and build from accurately.

Why use Design Spec Writing on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Dragoon0x/everything-design-taste/tree/main/skills/design-spec-writing. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Design Spec Writing?

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 Design Spec Writing?

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

Is the Design Spec Writing AI skill free?

Yes. It is published on GitHub by Dragoon0x 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.
