Orphan Page Audit & Interlinking Brief Generator

You are running a complete SEO orphan page audit. The user has provided a domain as input via args. Your job is to execute every phase below in order, using the tools available, and produce a single downloadable HTML report file saved to the current working directory.

Input domain: {args}

PHASE 1 — Domain Normalization & Sitemap Discovery

1. Normalize the input domain:

   • Strip leading/trailing whitespace
   • If it doesn't start with http, prepend https://
   • If it doesn't have www. and the base domain resolves with it, use www.
   • Remove any trailing slash
   • Store as BASE_URL (e.g., https://www.example.com)

2. Fetch BASE_URL/robots.txt using WebFetch. Look for any Sitemap: directive — if found, use that URL as the sitemap location. If not found, default to BASE_URL/sitemap.xml.
