SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Deploying code to production carries the risk that subtle bugs, performance regressions, and console errors can slip through testing and affect real users before you notice. This Skill automates post-deploy monitoring by watching the live application, taking screenshots, comparing against baselines, and alerting you to anomalies so you can catch issues early.

Core Features & Use Cases

  • Live Error Detection: Watches the live app for console errors, performance regressions, and page failures using the browse daemon.
  • Visual Baseline Comparison: Takes periodic screenshots and compares them against pre-deploy baselines to catch visual regressions.
  • Automated Alerting: Alerts on anomalies so you don't have to manually check production after every deploy.
  • Use Case: After shipping a new feature, run this Skill to verify the deploy didn't break anything in production. It will monitor the app, take screenshots, and notify you if it spots console errors, performance drops, or visual differences from the baseline.

Quick Start

Use the canary skill to monitor your production app for console errors, performance regressions, and visual anomalies after a deploy.

FAQPage Schema
How do I monitor my production application for console errors after a deployment?

To monitor production applications for console errors after a deployment, you can use an automated canary monitoring process that watches the live app and alerts you to anomalies. It uses a browse daemon to continuously detect page failures and performance regressions.

What is automated canary monitoring and how does it catch visual regressions?

Automated canary monitoring catches visual regressions by using a browse daemon to take periodic screenshots of your live production application. It compares these screenshots against pre-deploy baselines to automatically detect and alert on visual differences.

How do I set up post-deploy verification to catch performance regressions before users do?

Post-deploy verification to catch performance regressions requires taking pre-deploy baseline screenshots of your application. After deploying, an automated canary monitoring daemon continuously compares live application behavior against these baselines to alert on performance drops.

Can I use automated screenshot comparisons for continuous production monitoring?

Yes, you can use automated screenshot comparisons for continuous production monitoring. A browse daemon captures periodic screenshots of your live application and compares them against your pre-deploy baselines to catch visual and functional regressions before users report them.

Do I need pre-deploy baseline screenshots to detect page failures in production?

Yes, pre-deploy baseline screenshots are required for post-deploy verification workflows. The canary monitoring process relies on comparing live production screenshots against these baselines to accurately detect visual anomalies, page failures, and console errors.

What is the best way to alert on console errors without manually checking production after every deploy?

The best way to alert on console errors without manual production checks is to deploy an automated canary monitoring daemon. It continuously watches your live application for console errors, performance regressions, and page failures, automatically alerting you when anomalies are detected.
