SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy monitoring is hard to catch in production. This skill continuously watches the live app for console errors, performance regressions, and page failures, and compares against baselines.

Core Features & Use Cases

  • Real-time canary checks: monitor console errors, page failures, performance, and take periodic screenshots.
  • Baseline management: capture before-deploy baselines and post-deploy references to detect anomalies.
  • Guided remediation: alert with actionable insights and suggested next steps for operators.

Quick Start

Run /canary <URL> after deploy to begin 10 minutes of automatic monitoring, baseline capture, and page checks.

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

Post-deploy monitoring of a production URL surfaces console errors, performance regressions, and page failures by continuously checking the live app and comparing results against captured baselines.

What is canary monitoring and how does it catch performance regressions?

Canary monitoring captures pre-deploy baselines and periodic screenshots, then compares post-deploy page results against those baselines to detect anomalies and performance regressions early.

How do I start automated page checks and baseline capture for a live app?

Run a canary command with a production URL to begin automatic monitoring, baseline capture, and periodic page checks across configured pages for a set duration.

Can I configure the monitoring duration and specific pages to check?

Yes, canary monitoring operates via the browse daemon and supports configurable duration and pages, allowing you to target specific URLs for periodic screenshot collection and health checks.

Does canary monitoring work without external dependencies or components?

Canary monitoring operates via the browse daemon with no external dependencies or components, emitting structured health signals directly for alerting and reporting.

What is the best way to get actionable alerts for production page failures?

Canary monitoring emits structured health signals and alerts with actionable insights, providing guided remediation and suggested next steps for operators when page failures occur.
