  • 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 Design Mode 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.

  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/harshkedia177/design-mode/tree/main/plugin/skills/design-mode
  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/harshkedia177/design-mode.git /tmp/design-mode
mkdir -p .claude/skills
cp -r /tmp/design-mode/plugin/skills/design-mode .claude/skills/design-mode
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Design Mode 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 Mode 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 Mode 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 Mode — Activate/Deactivate Overlay

Inject or remove the Design Mode visual overlay on the current browser page.

Activation

Step 1: Search for and call the MCP activate tool

IMPORTANT: The tool may be deferred. Use ToolSearch first to find it:

  • Search for "design-mode activate" using ToolSearch
  • The tool name is either mcp__design-mode__activate (user MCP) or mcp__plugin_design-mode_design-mode__activate (plugin MCP)
  • Call whichever one exists with an optional url parameter

This connects to Chrome via CDP and injects the overlay. If it succeeds, report the element count and stop.

Step 2: ONLY if the MCP tool doesn't exist at all

Fall back to manual injection:

  1. Read the overlay script: search for **/design-mode/scripts/overlay.js
  2. Inject via any available browser MCP: preview_eval → javascript_tool → execute_javascript
  3. Take a screenshot to confirm

Do NOT skip to the fallback just because Chrome has a blank tab. The MCP activate tool accepts a url parameter to navigate first.

After Activation

Report:

  • Element count
  • Ctrl+Shift+D to toggle
  • Click to annotate, Shift+click for multi-select
  • "Copy to Claude" copies annotations to clipboard

Deactivation

  1. Call mcp__design-mode__deactivate (or mcp__plugin_design-mode_design-mode__deactivate)
  2. Fallback: execute window.__designMode._destroy() via browser MCP

Viewport Resize

  • mcp__design-mode__resize_viewport with width parameter
  • mcp__design-mode__reset_viewport to restore defaults

Frequently asked questions

What does the Design Mode AI skill do?

Activate or deactivate the visual Design Mode overlay on a web page in the browser. Use when the user says 'activate design mode', 'turn on design mode', 'start design mode', 'inject overlay', 'enable element inspection', or 'deactivate design mode', 'turn off design mode', 'remove overlay'.

Why use Design Mode on TypingMind?

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

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

Which AI models can use Design Mode?

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 Mode?

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

Is the Design Mode 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.
