playground

Live CSS playground for tweaking element styles in real-time in the browser. Use when the user says 'open css playground', 'let me tweak styles', 'live edit CSS', 'try different styles', 'experiment with styles', or wants to visually iterate on CSS before committing to source code.

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 harshkedia177 on GitHub. Read the source before you install it.

Installation

Install the Playground 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/harshkedia177/design-mode/tree/main/plugin/skills/playground
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/harshkedia177/design-mode.git /tmp/design-mode
mkdir -p .claude/skills
cp -r /tmp/design-mode/plugin/skills/playground .claude/skills/playground

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

Use it in TypingMind

Enable Playground 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 Playground 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 Playground 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.

CSS Playground — Live Style Tweaking

Apply temporary CSS changes to elements in the browser for visual iteration. Changes are applied via inline styles and can be committed to source code when the user is satisfied.

Apply Temporary Styles

Use mcp__design-mode__apply_style with:

selector: CSS selector of the element
styles: object of CSS property-value pairs (camelCase keys), e.g. {"fontSize": "20px", "color": "red"}

The tool automatically stores original styles for revert.

Take Before/After Screenshots

Take a screenshot before: mcp__design-mode__screenshot
Apply the style change
Take another screenshot after
Ask the user if they want to keep, adjust, or revert

Revert Styles

Use mcp__design-mode__apply_style with revert: true and the same selector.

Commit to Source

When the user says "commit this" or "save these styles":

Use mcp__design-mode__read_element to get the element's source file info
Locate the source file following ../references/source-lookup.md
Apply the style changes to the actual source file using Edit, following ../references/commit-to-source.md to match the project's styling approach

Common Style Tweaks

Interpret natural language into CSS:

"make it bigger" → increase font-size or dimensions
"more spacing" → increase padding, margin, or gap
"bolder" → font-weight: 700
"center it" → appropriate flex/grid/text-align centering
"red" / "blue" / any color → change color or background
"rounded" → increase border-radius
"shadow" → add box-shadow

Frequently asked questions

What does the Playground AI skill do?

Why use Playground on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/harshkedia177/design-mode/tree/main/plugin/skills/playground. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Playground?

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 Playground?

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

Is the Playground AI skill free?

It is published on GitHub by harshkedia177. Check the repository for licensing terms. 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.
