What problem does it solve? Deploys that pass CI can still break in production due to missing environment variables, stale CDN caches, or slow migrations. This Skill watches the live app after a deploy and catches regressions in the first minutes instead of hours. ## Core Features & Use Cases - Baseline Capture: Takes pre-deploy screenshots, console error counts, and load times per page, saved to a baseline manifest for later comparison. - Continuous Monitoring Loop: Checks each monitored page every 60 seconds for a configurable duration (1-30 minutes), comparing results against the baseline and alerting only on persistent changes across 2+ consecutive checks. - Severity-Based Alerts: Classifies findings as CRITICAL (page load failure), HIGH (new console errors), MEDIUM (2x load time regression), or LOW (new broken links), each with screenshot evidence. - Use Case: After deploying a new release, run the canary against your production URL for 10 minutes to verify the homepage, dashboard, and settings pages still load cleanly with no new console errors. ## Quick Start Ask the assistant to run /canary https://your-app.com to monitor the deployed site for 10 minutes and report any regressions against the baseline.
