About this skill
This skill compares two images using structural similarity indexing, highlights pixel-level differences with color-coded heatmaps, and generates side-by-side visualizations. It addresses the need to detect and quantify changes between image pairs, useful for quality control, before/after analysis, or automated testing workflows. Developers should use it when programmatic image comparison with visual output is required.
