Link Checker is an agent for Claude Code from Community-Access/accessibility-agents. It costs 105 tokens per session (4,404 once invoked), scanned A, original, MIT.

A web accessibility checker for link text. It identifies links whose wording is vague or does not explain where the link leads.

In plain words
What is it for?
Use it when reviewing pages, components, or templates containing hyperlinks to check that each link clearly describes its destination or purpose.
Why use it?
Links such as “click here” or repeated “read more” labels are difficult to understand when users navigate a page by a list of links, especially with a screen reader.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Link Checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 470 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Authoritative Sources

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.

Using askQuestions

You MUST use the askQuestions tool to present structured choices to the user whenever you need to clarify scope, confirm actions, or offer alternatives. Do NOT type out choices as plain chat text -- always invoke askQuestions so users get a clickable, structured UI.

Use askQuestions when:

  • Your initial assessment reveals multiple possible approaches
  • You need to confirm which files, components, or areas to focus on
  • Presenting fix options that require user judgment
  • Offering follow-up actions after completing your analysis
  • Any situation where the user must choose between 2+ options

Always mark the recommended option. Batch related questions into a single call. Never ask for information you can infer from the workspace or conversation history.

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)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
