At a glance

A skill your agent uses when applies to HTML documents with <li elements.

  • Applies to HTML documents with <li elements
  • SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Accessibility

What it does

Listitem is an agent skill from thedaviddias/Front-End-Checklist. Use when applies to HTML documents with <li elements. Also applies to custom ARIA lists where role='listitem' must be owned by role='list'. Common violations occur in templating systems where list markup is split across components or in CSS resets where developers use <li for layout without proper list parents.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

It sits in Frontend & Design, covering Accessibility. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Applies to HTML documents with <li elements
  • Tasks that involve Accessibility

Example prompts

  • “listitem”
  • “/listitem”

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Listitem loads about 819 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 411 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~819
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Place list items within list containers

When a <li> element exists outside a list container, screen readers lose the ability to announce critical context: NVDA and JAWS will not say 'list of 5 items' or 'item 2 of 5' because there is no list context. VoiceOver may announce the orphan <li> as plain text without any group context, stripping users of the structural information that helps them understand how many items exist and where they are in the list.

Quick Reference

  • Every <li> element must have a direct parent of <ul>, <ol>, or <menu>
  • Orphan <li> elements are invalid HTML per the HTML Living Standard
  • Screen readers announce list type and item count (e.g., 'list, 3 items') only when <li> is inside a valid list container
  • Similarly, role='listitem' must be owned by a role='list' element per WAI-ARIA requirements

Check

Find all <li> elements in the DOM. For each, check that its direct parent element is <ul>, <ol>, or <menu>. Flag any <li> whose parent is <div>, <section>, <nav>, <span>, or any element other than those three. Also check role='listitem' elements to ensure their closest ancestor with a list-related role is role='list'.

Fix

For each orphan <li>: (1) Wrap it and any sibling <li> elements in the appropriate list container — use <ul> for unordered items or <ol> for sequentially ordered items. (2) If the <li> was being used purely for styling (e.g., a bullet point visual), replace it with a <div> or <p> and apply the visual style via CSS. (3) If inside a navigation element, ensure <nav><ul><li> nesting is maintained.

Explain

The HTML Living Standard specifies that <li> elements are only valid as children of <ul>, <ol>, or <menu>. This is a structural requirement, not a style preference. Screen readers use the list container to announce the list type ('bullet list' vs 'numbered list') and the total item count. Without the container, this context is lost entirely. Additionally, when list-style: none is applied to a <ul>, some browsers strip the list semantics — if this is intentional (e.g., a navigation menu), add role='list' to the <ul> to restore list semantics for screen readers.

Code Review

Review the rendered markup and interactive states that affect Place list items within list containers. 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.
