    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when the user wants a public website or web page checked for accessibility (WCAG 2.1/2.2 AA, ADA, EAA, Section 508): it loads the live page in a real browser, runs axe-core on it and up to two more same-site pages, and returns a 0-100 score, a letter grade and the failing rules with example elements. Takes 15-40 seconds. Do not use it for pages that need a login, for localhost or private-network addresses, or for pasted HTML.

    Annotations the server declares

    Why it is in this group

    • The name "explain_accessibility_issue" says "explain": a word for reading.
    Description, as the server wrote it
    Use this when the user asks what an axe-core accessibility rule means or how to fix it — typically a ruleId returned by scan_accessibility, such as color-contrast, image-alt, label or link-name. Returns plain-English steps and a code example. Do not use it to scan a site; use scan_accessibility for that.

    Annotations the server declares

    • title: Explain how to fix an accessibility rule
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
