SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring detects production issues quickly by watching a live URL for console errors, performance regressions, and page failures, and by validating visual baselines.

Core Features & Use Cases

  • Watches the live app via the browse daemon to collect screenshots, console logs, and load times.
  • Compares against baselines and applies a defined alerting policy to catch regressions early.
  • Supports baseline capture, per-page monitoring, and persistent issue reporting to guide remediation.

Quick Start

Run /canary <url> to begin monitoring the deployed site for a defined duration with automatic baseline capture and alerting.
