Sitemap Cohort Auditor

Sitemap Cohort Auditor is documented as a dependency-free Node.js CLI for reading local or HTTPS sitemap inputs, including compressed XML files and nested indexes. Its reports cover URL and image entries, duplicates, hosts, schemes, last-modified metadata, and additions or removals between inputs. The repository documentation was reviewed, but the CLI was not installed or run, so parsing and report accuracy remain untested.

The README describes comparing the exact decoded URL strings declared in two sitemap inputs. An optional policy file can set allowed hosts and schemes, URL-count limits, and a maximum number of removals. JSON output and distinct exit codes make the result usable in a release check. A completed command can still report findings; maintainers need to distinguish a successful read from a passing policy. The documented policy behavior was not exercised.

This may fit a developer or site maintainer checking generated sitemap output before a release. An unexpected drop in URLs or a change of host is a concrete thing to investigate before shipping. The tool audits declarations rather than crawling the pages they name: it does not establish whether a page loads, uses the intended canonical URL, gets indexed, or performs well in search.

The optional policy gate turns an expected change into a rule that can be checked again on the next release. The README also documents limits on remote inputs, including same-origin HTTPS child maps and redirects. Those boundaries help explain the intended scope, but they are documentation claims rather than a security or runtime test.
