Tools as reported by the server

Run a deterministic technical SEO audit for a public website URL. Checks canonicals, title tags, headings, robots.txt, sitemaps, redirects, crawl traps, and indexability.
transpile_to_caddyfile
Transpile Nginx (nginx.conf, server blocks) or Apache (.htaccess, VirtualHost) web server configuration to clean, idiomatic Caddyfile with migration advisories.
calculate_cidr_overlap
Analyze IPv4/IPv6 CIDR subnets for range collisions, full containment, 2D bit-tree matrix partition, and available free subnet allocation.
diagnose_cors_policy
Analyze CORS HTTP request and response headers for wildcard/credential security violations, missing Vary: Origin, preflight OPTIONS handling, and header exposure.
trace_dns_delegation
Query live DNS records and inspect the authoritative nameservers returned for a domain.

Generate modern multi-platform favicon bundle (adaptive dark-mode SVG, multi-resolution ICO, Apple Touch Icon, Android PWA icons, webmanifest) and minimal HTML tags from SVG or image input.
