Geofeed Tuner

If you run a network and need to tell geolocation providers where your IP blocks actually are, this builds and validates RFC 8805 compliant geofeeds in CSV format. It checks structure, validates against the standard, and applies opinionated best practices from real deployments. The skill includes a six-phase pipeline that downloads feeds, runs quality checks, fetches tuning data via Fastah's MCP tool, and generates HTML reports. It's aimed at ISPs, hosting providers, and anyone tired of seeing their Sydney datacenter geolocated to San Francisco. Won't help with private IPs, only publicly routable space.
