What This Skill Does

Canary monitors a live app after a deploy by checking pages for console errors, performance regressions, and load failures. It takes periodic screenshots, compares them against pre-deploy baselines, and alerts when something changes. Run it after shipping to catch production issues before users report them. Instead of manually refreshing pages and checking DevTools after every deploy, canary automates the comparison against a known-good baseline so you catch regressions in minutes, not hours.
