SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring watches the live app for console errors, performance regressions, and page failures, using the browse daemon to detect issues before users notice.

Core Features & Use Cases

  • Baseline capture and comparison, screenshots, and alerts when anomalies appear.
  • Continuous monitoring of a set of pages after deploy, with configurable duration and pages.
  • Automatic health signals and reporting for post-deploy validation.

Quick Start

Invoke /canary with a URL to begin post-deploy monitoring (duration and pages can be customized).

Frequently Asked Questions about canary

High-intent search queries and answers about installing and using this skill.

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

Post-deploy canary monitoring watches a live URL for console errors, performance regressions, and page failures using the browse daemon to detect production site issues immediately after deployment.

What is baseline comparison in post-deploy canary monitoring?

Baseline comparison in canary monitoring captures the normal performance and error metrics of a page before deployment, then compares live post-deploy metrics against this baseline to flag visual or metric-based anomalies.

How do I set up continuous monitoring for specific pages following a production release?

You can invoke the canary monitoring Skill with a target URL to begin continuous monitoring of specific production pages, customizing the monitoring duration and page selection to validate post-deploy health.

Do I need a baseline capture before using a canary monitoring process?

Yes, baseline capture is a required prerequisite for canary monitoring to enable accurate post-deploy comparison, allowing the system to detect performance regressions and page failures against known good metrics.

What is the best way to validate production reliability and health across targeted pages after a release?

The best way to validate production reliability is using post-deploy canary monitoring, which provides automatic health signals, screenshots, and alerts by continuously watching targeted pages for anomalies.
