A post-release monitor for a live web application. It checks for console errors, slowdowns, page failures, and visual changes by taking periodic screenshots and comparing them with earlier versions.

In plain words
What is it for?
Use it to watch a deployment, check a production site, and receive alerts when the application behaves or looks different from its baseline.
Why use it?
Problems can appear after deployment even when tests passed beforehand. This helps detect unexpected production issues without waiting for users to report them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

canary scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
