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

Installation

Install the Create Html Component 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/videojs/v10/tree/main/.agents/skills/create-html-component
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/videojs/v10.git /tmp/v10
mkdir -p .claude/skills
cp -r /tmp/v10/.agents/skills/create-html-component .claude/skills/create-html-component

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

Use it in TypingMind

Enable Create Html Component 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 Create Html Component 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 Create Html Component 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.

HTML component implementation

Read the relevant core contract, nearest HTML element and tests, definition entry, and UI design record before choosing a pattern. Use packages/html/src/ui/play-button/ for a simple control and packages/html/src/ui/slider/ for a compound control. Read packages/element/README.md when changing reactive properties, lifecycle, or controllers.

Workflow

Classify the request as a reusable primitive or app/skin composition before defining its contract. Then define the state owner, semantics, APIs, optional parts, styling contract, and opt-outs.
Put runtime-neutral state and actions in packages/core/src/core/ui/; put reusable DOM interaction in packages/core/src/dom/ui/; keep the element an adapter.
Match the nearest UIElement or MediaButtonElement pattern. Send properties down and semantic events up; use controllers or context only across a real ownership boundary.
Let ReactiveElement own rendered DOM updates: derive changes from reactive properties and controller state, then apply them through its update lifecycle. Avoid out-of-band mutations so scheduling, updateComplete, tests, and integrations remain authoritative.
Add markup for semantics, focus, content, or parts consumers must place, omit, or replace. Leave purely visual structure to skins, CSS, or pseudo-elements. If the API starts coordinating independent behavior, extract another element or controller instead of adding modes and options.
Expose discrete state through mapped data-* attributes and dynamic layout values through stable CSS custom properties. Define each token's owner, units, and fallback. Treat descendant selectors, :has(), and other complex selectors introduced by composition as a likely sign that the primitive boundary or styling hooks need improvement.
Keep the element class free of registration side effects. Register it with safeDefine under packages/html/src/define/ui/, update HTMLElementTagNameMap, and preserve narrow import and sideEffects boundaries.
Clean up subscriptions, observers, listeners, locks, and async work across disconnect and destroy. Add focused core and HTML tests; verify interaction in a browser when semantics, focus, or pointer behavior changes.

Check packages/html/package.json and packages/html/vite.config.ts when adding an entrypoint or registration module. Run the narrow package tests and build; build changed exported types before repository typechecking.

Example

Input: “Create the HTML chapter-skip control.”

Output: A scoped core contract, thin custom element, explicit definition entry, headless styling hooks, cleanup, and focused tests.

Frequently asked questions

What does the Create Html Component AI skill do?

Create or change Video.js custom-element UI components. Use for HTML component boundaries, properties, events, controllers, light-DOM parts, styling hooks, registration, or lifecycle.

Why use Create Html Component on TypingMind?

Because you install it once and use it with any model. Create Html Component 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 Create Html Component in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/videojs/v10/tree/main/.agents/skills/create-html-component. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Create Html Component?

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 Create Html Component?

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

Is the Create Html Component AI skill free?

It is published on GitHub by videojs. 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.
