This skill should be used when the user says "visual strategy", "arn visual strategy", "visual testing", "visual regression", "screenshot testing", "compare to prototype", "visual validation", "how do I test visuals", "set up visual tests", "baseline images", "screenshot comparison", "pixel diff", "visual diff", "does it match the prototype", or wants to set up visual regression testing for development — creating capture scripts, comparison scripts, and baseline images so that feature implementations are automatically compared against prototype screenshots to catch visual regressions during development.
