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. Takes periodic screenshots, compares against pre-deploy baselines, and alerts on anomalies. Use when: "monitor deploy", "canary", "post-deploy check", "watch production", "verify deploy".

Core Features & Use Cases

Setup and baseline capture to establish a reference health.
Auto-discovery of critical pages and continuous monitoring with alerting.
Centralized telemetry and reports for post-deploy health.

Quick Start

Provide a URL, then start 10 minutes of automated canary checks with default pages and baseline capture.

FAQPage Schema

How do I monitor production for errors after a deploy?▼

Post-deploy monitoring watches a live URL for console errors, performance regressions, and page failures. It takes automated baselines, periodic screenshots, and alerts on anomalies via the browse daemon.

What is canary monitoring for production health checks?▼

Canary monitoring establishes pre-deploy baseline health and then continuously watches the live app for regressions. It coordinates baseline capture, page discovery, and ongoing health checks to catch post-deploy issues fast.

How do I start an automated post-deploy check on a live URL?▼

Provide a URL to start automated canary checks. A 10-minute monitoring session begins with default pages and baseline capture to establish reference health and alert on anomalies.

Does post-deploy canary monitoring require external dependencies?▼

No external dependencies are required. The skill uses the browse daemon internally to coordinate multi-phase workflows including baseline capture, pre-deploy snapshots, and ongoing health checks.

What is the best way to catch performance regressions after releasing?▼

Automated post-deploy canary checks capture baseline metrics and take periodic screenshots to compare against pre-deploy states. This approach alerts you to performance regressions and page failures immediately.

When should I not use automated canary checks for production?▼

Canary checks are designed for post-deploy verification of live URLs. They are not suited for pre-deploy testing or monitoring environments without accessible web pages for the browse daemon to capture.
