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.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by thedaviddias on GitHub. Read the source before you install it.

Installation

Install the Aria Required Children 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.
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/thedaviddias/Front-End-Checklist.git /tmp/Front-End-Checklist
mkdir -p .claude/skills
cp -r /tmp/Front-End-Checklist/skills/aria-required-children .claude/skills/aria-required-children

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

Use it in TypingMind

Enable Aria Required Children 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 Aria Required Children 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 Aria Required Children 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.

Ensure ARIA roles contain required child roles

Screen readers like NVDA and VoiceOver navigate composite widgets (menus, tabs, trees) by moving between the required child roles. If a tablist contains <div> elements instead of role='tab', the user hears no tabs at all. JAWS announces 'list of 5 items' only when role='listitem' children exist inside role='list'. Without correct nesting, the entire widget becomes opaque to keyboard-only and screen reader users.

Quick Reference

Container roles mandate specific owned child roles: tablist → tab, list/listbox → listitem/option, menu/menubar → menuitem, tree → treeitem, grid/rowgroup → row
Missing required children break the accessibility tree so screen readers cannot enumerate items or announce counts
Use role='none' or role='presentation' on purely structural wrapper elements inside the container to avoid invalid nesting
Applies to WAI-ARIA 1.2 required owned elements for composite widget roles

Check

Identify all elements with ARIA container roles (tablist, list, listbox, menu, menubar, tree, treegrid, grid, rowgroup, radiogroup). For each, verify it contains the required owned child roles per the WAI-ARIA spec: tablist must own tab elements; list must own listitem; listbox must own option; menu/menubar must own menuitem, menuitemcheckbox, or menuitemradio; tree must own treeitem; grid must own row (which owns gridcell); radiogroup must own radio. Flag any container roles missing required children.

Fix

For each container role missing its required children: (1) Add the correct role to each child element — e.g., add role='tab' to each tab button inside role='tablist'. (2) If wrapper <div> elements exist between the container and the required children for layout purposes, add role='none' or role='presentation' to those wrappers. (3) Prefer native HTML equivalents where possible: <ul>/<li> instead of role='list'/role='listitem', <select>/<option> instead of role='listbox'/role='option'.

Explain

WAI-ARIA 1.2 defines 'required owned elements' for composite widget roles — these are the child roles a container must contain for the widget to be valid. Screen readers build their understanding of a widget from this structure. A tablist without tab children means a screen reader user in Forms Mode will find nothing to navigate between. A menu without menuitem children will not be announced as a menu at all in some ATs. This is distinct from aria-required-parent, which checks the inverse direction.

Code Review

Review the rendered markup and interactive states that affect Ensure ARIA roles contain required child roles. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.

Frequently asked questions

What does the Aria Required Children AI skill do?

Why use Aria Required Children on TypingMind?

Because you install it once and use it with any model. Aria Required Children 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 Aria Required Children in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/thedaviddias/Front-End-Checklist/tree/main/skills/aria-required-children. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Aria Required Children?

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 Aria Required Children?

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

Is the Aria Required Children AI skill free?

It is published on GitHub by thedaviddias. 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.
