testing-visual-regression

Quick Review

The skill addresses visual regression testing but suffers from significant gaps. The description mentions 'screenshot comparison' and 'pixel differences' but the SKILL.md provides only generic testing workflow without visual-specific implementation details (no screenshot capture tools, image comparison libraries, or diff threshold configurations). Task knowledge is weak—no concrete tools (Puppeteer, Playwright, Percy, Applitools), no image diff algorithms, and no example commands are provided. Structure is reasonable with clear sections, though somewhat verbose for the limited specific content. Novelty is low: visual regression testing tools are readily available and well-documented; a CLI agent could easily invoke existing tools like BackstopJS or Percy with comparable effort. The skill would benefit from concrete screenshot capture scripts, specific image comparison tooling (pixelmatch, looks-same), and threshold configuration examples to justify its existence over direct tool usage.
