At a glance

Create or update ARIA accessibility annotations and validate WCAG compliance for a Kendo UI component.

  • Works in 6 steps: Gather context → Add @aria annotations → Apply ARIA attributes in JSX → …
  • The user wants to add accessibility support
  • SKILL.md covers When to use, Inputs, Architecture and JSDoc annotation system, plus 2 more sections
  • Calls npm; reaches w3.org

What it does

Manage HTML A11y is an agent skill from telerik/kendo-themes. Create or update ARIA accessibility annotations and validate WCAG compliance for a Kendo UI component. Reads the component spec, writes @aria/@keyboard/@ux/@see JSDoc annotations, applies attributes to TSX templates, and validates with the axe-core test runner. Use this skill when the user wants to add accessibility support, fix ARIA violations, document keyboard shortcuts, or ensure WCAG 2.2 Level AA compliance.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/ariaspec-reference.md`). Compatibility notes: Requires Node.js with npm, and a built HTML package

It sits in Frontend & Design, covering Accessibility. The repository describes itself as: Monorepo for SASS-based Kendo UI themes.

When your agent uses it

  • The user wants to add accessibility support
  • Fix ARIA violations
  • Document keyboard shortcuts
  • Ensure WCAG 2.2 Level AA compliance

Example prompts

  • “/manage-html-a11y”

Requirements

  • Node.js
  • Compatibility (from SKILL.md): Requires Node.js with npm, and a built HTML package

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Gather context
  2. Add @aria annotations
  3. Apply ARIA attributes in JSX
  4. Add @keyboard and @see to the bottom block
  5. Validate WCAG compliance
  6. Regenerate docs

What it can do on your machine

Read from SKILL.md and the folder at commit 00ae7da. 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

    Shell commands in SKILL.md call:

    • npm

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • w3.org

    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.

  • Compatibility

    Requires Node.js with npm, and a built HTML package

    From compatibility in the SKILL.md frontmatter.

Context cost

Manage HTML A11y loads about 2k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 498 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.6k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 498 words (~2,006 tokens).

“Document ARIA attributes as JSDoc annotations in component specs and validate WCAG 2.2 Level AA compliance.”
