FAQPage Schema
How do I check web page accessibility violations against a git branch baseline?▼

To check web page accessibility violations against a baseline, this Skill compares a live page's audit results against a specified Git branch or uncommitted changes, reporting newly introduced and fixed issues.

How do I diff accessibility issues introduced by uncommitted changes?▼

To diff accessibility issues from uncommitted changes, the Skill scans the live page and compares violations against the baseline, isolating only new issues and resolved violations while tracking pre-existing counts.

Do I need @accesslint/cli to scan live pages for accessibility compliance?▼

Yes, you need both @accesslint/cli and @accesslint/chrome installed, as the Skill relies on these dependencies to scan live web pages and ensure compliance with accessibility standards.

Can I generate a full accessibility audit without comparing it to a baseline?▼

Yes, you can generate a full accessibility audit without baseline comparison, which provides a comprehensive analysis of all current violations on the target web page without diffing.

What is the best way to automate accessibility checks for a specific URL?▼

To automate accessibility checks for a specific URL, the Skill uses a configurable target approach, allowing you to pass a URL directly, use a config target name, or default to accesslint.config.json.

Why should I use an accessibility diff instead of a full audit during code review?▼

An accessibility diff is ideal for code review because it filters out pre-existing violations and reports only new issues introduced or fixed, reducing noise and focusing on branch-specific changes.
