Defined in:

Overview

Audits ERB templates (and plain HTML) by parsing them in-process with the Herb gem, then looking up every HTML element and global attribute against the bundled MDN browser-compat-data snapshot.

No external tools are needed — Herb is a gem dependency — so ERB/HTML analysis works on a machine with nothing else installed.
