agent-browser adds axe-core accessibility audits

Introduced 2026-07-23 · score 0.99

HOW TO USE IT

When auditing a page, run the `a11y` command with its URL, optionally filtering axe tags, scoping to a selector, or requesting JSON output. The audit uses an embedded axe-core engine and requires a CDP browser.

WHY THIS HELPS

Audit a web page's accessibility while developing or reviewing its code.

REQUIREMENTS AND LIMITATIONS

• Version: v0.33.0
• <url>: URL to navigate to before auditing; omit it to audit the current page.
• --tags <tags>: Limit rules by comma-separated axe tags, such as `wcag2a,wcag2aa`.
• --selector <selector>: Scope the audit to a subtree selected by CSS.
• --json: Return structured results, including counts, violations, and incomplete checks.
• Prerequisite: Requires a CDP browser; unavailable with Safari or iOS WebDriver sessions.
