SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill finds layout issues where content spills outside its container, gets clipped at the edge, or hides important columns and badges behind horizontal scrolling.

Core Features & Use Cases

  • Horizontal overflow detection: Flags containers whose scroll width exceeds their client width by a meaningful margin, helping prevent unwanted page scroll.
  • Clipped badges and chips: Detects status pills, tags, and badges that are partially cut off in tables or scrollable panels.
  • Hidden table columns: Identifies cases where the rightmost table column is clipped at the initial view, so action buttons or statuses are not visible without scrolling.
  • Use case: Run it during responsive QA to catch layout regressions on dashboards, data tables, forms, and dense UIs before release.

Quick Start

Ask the agent to scan the current page for horizontal overflow and clipped badges on mobile, tablet, laptop, and desktop viewports.

FAQPage Schema
How do I detect horizontal overflow and clipped badges during responsive UI audits?

You can detect horizontal overflow by evaluating the browser DOM to compare scrollWidth against clientWidth across mobile, tablet, laptop, and desktop viewports. This flags containers where content spills outside its boundaries and identifies partially clipped badges and chips.

What causes hidden rightmost table columns in responsive layouts?

Hidden rightmost table columns occur when table content exceeds the container width, clipping action buttons or statuses at the initial view. Scroll ancestor boundaries and viewport-sensitive checks identify these hidden columns without requiring manual horizontal scrolling.

Can I scan for layout regressions on dense dashboards and data tables?

Yes, you can scan dense dashboards and data tables for layout regressions by running viewport-sensitive DOM checks. This evaluates scrollable containers, status pills, and clipped last-column rendering across mobile, tablet, laptop, and desktop scenarios before release.

What's the best way to catch content spilling outside scrollable containers?

The best way to catch content spilling outside scrollable containers is applying browser DOM evaluation that checks scroll ancestor boundaries and viewport width margins. This detects visible layout defects where content gets clipped at the edge or hides important elements.

Does horizontal overflow detection work on mobile and tablet viewports?

Yes, horizontal overflow detection works on mobile and tablet viewports by applying responsive UI audits. It checks scrollWidth and clientWidth metrics across multiple screen sizes to ensure badges, chips, and table columns render correctly without unwanted page scroll.
