SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a safety net after deploys by continuously monitoring production URLs for console errors, performance regressions, and page failures using a browse daemon and baseline comparisons.

Core Features & Use Cases

  • Baseline capture and comparison against pre-deploy state
  • Continuous monitoring of selected pages with periodic checks
  • Health reporting and concise post-run summaries including actionable alerts

Quick Start

Type /canary <url> to start a 10-minute live canary monitoring session on your production site.

FAQPage Schema
How do I monitor production URLs for console errors and performance regressions after a deploy?

Post-deploy canary monitoring uses a browse daemon to continuously check live production URLs, detecting console errors, performance regressions, and page failures by comparing real-time metrics against a pre-deploy baseline.

What is baseline comparison in canary monitoring for production reliability?

Baseline comparison in canary monitoring captures pre-deploy page metrics like performance and error rates, then compares them against live production data to quickly identify regressions introduced by the new deployment.

How do I start a canary monitoring session for a live web app?

You can start a 10-minute live canary monitoring session by entering the /canary command followed by your target production URL, which initiates baseline capture, page discovery, and continuous health reporting.

Does canary monitoring work without external dependencies or components?

Yes, this canary monitoring runs as a standalone process with no external dependencies or components required, using only an internal browse daemon to discover pages, capture baselines, and generate structured health alerts.

What is included in the health reporting for post-deploy canary checks?

Health reporting for post-deploy canary checks includes concise post-run summaries with actionable alerts for console errors and performance regressions, plus page-level prompts generated to guide immediate remediation of detected failures.

Can I update the monitoring baseline during an ongoing canary session?

Yes, the canary workflow supports optional baseline updates during continuous monitoring, allowing you to refresh the stored pre-deploy snapshot if you need to reset performance or error thresholds mid-session.
