## Tools (as reported by the server, not verified)

- `validate\_app\_links`: Inspect and validate Apple App Site Association \(apple-app-site-association\) and Android Digital Asset Links \(assetlinks.json\) files, HTTPS hosting rules, and test URL path routing, and compare the origin AASA with the copy on Apple's CDN.
- `audit\_website\_seo`: 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.
- `inspect\_domain\_security`: Inspect domain email security and deliverability standards: DMARC \(BIMI compliance\), BIMI DNS & SVG reachability, MTA-STS \(RFC 8461\), SMTP TLS-RPT \(RFC 8460\), SPF and MX records.
- `generate\_favicon\_suite`: 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.
- `analyze\_geo\_readiness`: Analyze Generative Engine Optimization \(GEO\) signals and AI crawler readiness for a web page \(schema, citations, provenance, answer structure, llms.txt, AI bot robots rules\).
- `inspect\_apple\_pkpass`: Inspect and validate Apple Wallet .pkpass JSON structure \(pass.json\) or package manifests: checks required keys, pass styles, dates, ISO 8601 timezones, transit types, barcodes, and color contrast.
- `generate\_apple\_pkpass\_spec`: Generate a production-ready, fully compliant Apple Wallet pass.json specification based on pass type, metadata, colors, barcode, and field values.
- `repair\_apple\_pkpass\_spec`: Automatically repair and sanitize broken Apple Wallet pass.json manifests: fixes missing formatVersion, prefixes passTypeIdentifier, ensures 10-character team ID, normalizes dates to ISO 8601 with timezones, and auto-corrects low contrast.
- `transpile\_regex\_engine`: Transpile and analyze regular expressions across engines \(PCRE, Go RE2, JavaScript, Python re, Rust regex\) with compatibility checks and ReDoS safety analysis.
