Audit fixed-viewport HTML slides for excessive whitespace by rasterizing visible content onto a grid and computing coverage ratio
Set up
Skills are installed by placing their folder where your agent loads skills.
The download comes from github.com/tsaijamey/slide-whitespace-audit itself, not from our server, so what you get is exactly what its author published.

What this skill does
This skill turns any 1280x720 (or other fixed-viewport) slide HTML into a quantitative density report. It rasterizes every visible text node, image, and SVG onto a coarse grid, computes the uncovered fraction of the viewport, and flags slides that fall into the common "sparse content collapsed at top, big empty area below" failure mode that LLM-generated slides exhibit. Outputs sortable per-slide whiteRatio, coverage, and threshold bands so reviewers can triage a deck in seconds.
When to use
This skill should be used when auditing slide HTML files (1280x720 or other fixed-viewport layouts) for the common design anti-pattern of excessive whitespace and insufficient information density. It computes a quantitative whiteRatio by rasterizing all visible content elements (text nodes, images, SVGs, canvases, videos) onto a coarse grid and calculating the uncovered fraction of the viewport. Use after an LLM or sub-agent generates slide HTML to catch under-filled layouts before review. Trigger phrases: whitespace audit, slide design audit, coverage ratio, information density check, slide layout review, check slide for empty space, audit my slides, slide HTML coverage analysis, design density check, layout density audit.
