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

Installation

Install the Responsive Testing 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/spencerpauly/awesome-cursor-skills/tree/main/resources/responsive-testing
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/spencerpauly/awesome-cursor-skills.git /tmp/awesome-cursor-skills
mkdir -p .claude/skills
cp -r /tmp/awesome-cursor-skills/resources/responsive-testing .claude/skills/responsive-testing

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

Use it in TypingMind

Enable Responsive Testing 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 Responsive Testing 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 Responsive Testing 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.

Responsive Testing

After a UI change, verify the app looks correct at all standard breakpoints.

Viewports to Test

Workflow

1. Navigate to the Page

Use browser_navigate to open the target URL (usually http://localhost:3000 or whatever the dev server is running on).

2. Test Each Viewport

For each viewport size:

Resize the viewport using browser_navigate with viewport parameters, or use browser_snapshot to inspect the layout
Take a screenshot with browser_take_screenshot
Check browser_snapshot for the aria tree — look for:
- Content overflowing or hidden behind other elements
- Navigation that should collapse into a hamburger menu
- Text that's too small to read
- Buttons/links too close together (touch target issues)
- Horizontal scrollbars that shouldn't exist

3. Check for Common Breakage

Overflow: Elements wider than the viewport causing horizontal scroll
Collapsed layout: Flex/grid items that should stack on mobile but don't
Hidden content: Elements that disappear at certain sizes without a menu toggle
Font scaling: Text that's readable on desktop but tiny on mobile
Fixed positioning: Modals, toasts, or sticky headers that break on small screens
Images: Oversized images that don't scale down

4. Report


Responsive Test Results:
  375px (mobile):  PASS — layout stacks correctly
  428px (mobile):  PASS
  768px (tablet):  WARN — nav items overlap, need hamburger menu
  1280px (desktop): PASS
  1536px (ultrawide): WARN — content not centered, stretched too wide

Fix any issues found, then re-test the affected viewports.

Frequently asked questions

What does the Responsive Testing AI skill do?

Open the app in Cursor's browser at multiple viewport sizes, screenshot each, and report any layout breakage.

Why use Responsive Testing on TypingMind?

Because you install it once and use it with any model. Responsive Testing 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 Responsive Testing in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/spencerpauly/awesome-cursor-skills/tree/main/resources/responsive-testing. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Responsive Testing?

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 Responsive Testing?

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

Is the Responsive Testing AI skill free?

Yes. It is published on GitHub by spencerpauly under the CC0-1.0 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.
