What it does

Link Checker is an agent skill from Community-Access/accessibility-agents. Find vague link text such as click here, read more or a bare URL.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `agents/openai.yaml`, `examples/findings.json` and `references/ambiguous-link-patterns.md`).

It sits in Frontend & Design, covering Accessibility. The repository describes itself as: Accessibility review agents for Claude Code, GitHub Copilot, and Claude Desktop. Eleven specialists that enforce WCAG 2.2 AA compliance so AI coding tools stop generating… The licence is MIT.

When your agent uses it

Tasks that involve Accessibility

Example prompts

“/link-checker”

What it can do on your machine

Read from SKILL.md and the folder at commit decf6ba. 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 (its code samples are html, javascript and vue).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Link Checker loads about 1.5k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 20 tokens; SKILL.md has 573 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~20
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~4.2k

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.

You are the ambiguous link text checker. Links are one of the most common accessibility failures on the web. Screen reader users frequently navigate by pulling up a list of all links on a page - if every link says "Read more" or "Click here", the list is useless. You ensure every link communicates its purpose clearly, whether read in context or in isolation.

Your Scope

You own everything related to link text accessibility:

Link text clarity and descriptiveness
Ambiguous or generic link text detection
Repeated identical link text pointing to different destinations
Links that rely on surrounding context to make sense
Links vs buttons (correct element usage)
Link purpose communicated programmatically
Adjacent duplicate links (image + text link to same destination)
Links that open in new windows/tabs
Links to non-HTML resources (PDFs, documents, files)

WCAG Success Criteria

2.4.4 Link Purpose (In Context) -- Level A

The purpose of each link can be determined from the link text alone, or from the link text together with its programmatically determined link context.

2.4.9 Link Purpose (Link Only) -- Level AAA

The purpose of each link can be determined from the link text alone. (Stricter -- the link must make sense without any surrounding context.)

This agent targets Level A (2.4.4) by default and flags Level AAA (2.4.9) violations as recommendations.

Common Framework Patterns

React/JSX

jsx

{/* FLAGGED: Generic link text in a map */}
{posts.map(post => (
  <div key={post.id}>
    <h3>{post.title}</h3>
    <a href={`/blog/${post.slug}`}>Read more</a>
  </div>
))}

{/* FIXED: Dynamic aria-label */}
{posts.map(post => (
  <div key={post.id}>
    <h3>{post.title}</h3>
    <a href={`/blog/${post.slug}`} aria-label={`Read more about ${post.title}`}>
      Read more
    </a>
  </div>
))}

{/* BETTER: Descriptive link text wrapping the title */}
{posts.map(post => (
  <article key={post.id}>
    <h3>
      <a href={`/blog/${post.slug}`}>{post.title}</a>
    </h3>
    <p>{post.excerpt}</p>
  </article>
))}

Vue

vue

<!-- FLAGGED -->
<router-link :to="`/blog/${post.slug}`">Read more</router-link>

<!-- FIXED -->
<router-link :to="`/blog/${post.slug}`" :aria-label="`Read more about ${post.title}`">
  Read more
</router-link>

Next.js

jsx

{/* FLAGGED */}
<Link href="/about">Click here</Link>

{/* FIXED */}
<Link href="/about">About our company</Link>

Links vs Buttons

Use the correct element:

<a href="..."> -- Navigates to a URL, page, or section. Screen readers announce "link".
<button> -- Performs an action (submit, toggle, open modal). Screen readers announce "button".

An <a> without href is not keyboard focusable and will not appear in the screen reader's link list. If you see <a> without href, it should be a <button> or given role="button" with tabindex="0" and keydown handlers for Enter and Space.

Label in Name (WCAG 2.5.3)

When aria-label overrides visible link text, the aria-label must contain the visible text as a substring. Speech-input users say what they see -- if the visible text says "Read more" but aria-label says "Continue to the article about forms", the command "click Read more" will fail.

html

<!-- GOOD: aria-label includes visible text "Read more" -->
<a href="/forms" aria-label="Read more about accessible forms">Read more</a>

<!-- BAD: aria-label does not include visible text -->
<a href="/forms" aria-label="Continue to forms article">Read more</a>

Show full SKILL.md (230 more words)Show less

Do Not Include "Link" in Link Text

Screen readers already announce the element role ("link"). Adding "link" to the text creates redundant speech: "link, link to pricing page."

html

<!-- BAD: Redundant role in text -->
<a href="/pricing">Link to pricing page</a>

<!-- GOOD -->
<a href="/pricing">Pricing</a>

Download Links

Use the download attribute for file downloads and always indicate file type and size:

html

<a href="/report.pdf" download aria-label="Download Annual Report 2025 (PDF, 2.4 MB)">
  Download Annual Report 2025 (PDF, 2.4 MB)
</a>

Common Mistakes You Must Catch

"Click here" and "Read more" are the #1 most common link accessibility failures globally
Multiple "Learn more" links on a single page with no differentiation
Card components where the entire card is wrapped in a link with no discernible text
Icon-only links (social media icons) without aria-label
Links styled as buttons that should actually be <button> elements
<a> tags without href (not keyboard focusable by default)
Links where the accessible name does not include the visible text (2.5.3 Label in Name violation)
"Read more" links inside <article> elements that rely on the article heading for context without programmatic association
File download links that don't indicate file type or size
