Geofeed Desk - notice This app is a derived work of the agent skill "geofeed-tuner" (version 0.0.9) by Sid Mathur / Fastah Inc., published in github/awesome-copilot at skills/geofeed-tuner (commit 421418928715158da3610571cb9e9cbb18d4747d, fetched 2026-09-28) and originally developed at fastah/ip-geofeed-skills. The skill declares license: Apache-2.0 in its SKILL.md front matter and plugin.json; the fastah/ip-geofeed-skills repository is Apache-2.0; the github/awesome-copilot repository as a whole is MIT. What this app takes from the skill: - the Validation Rules Reference: rule IDs 1101-3402, their types, texts and auto-tunable flags, reproduced in geokit.js; - the report-data.json schema (the "report-data.json" export); - the data tables assets/iso3166-1.json, assets/iso3166-2.json and assets/small-territories.json, reproduced in isodata.js with the flag emoji dropped and codes and names unchanged (sha256 of the originals are recorded in the header of isodata.js). The skill does not say where these tables were compiled from. Changes: the checks are reimplemented in JavaScript for the browser; checks the skill leaves to the agent or does not make are added under "A" rule IDs; the skill's Fastah place-lookup phase (an MCP service) is not used - the model lane replaces it and every proposal is re-checked in the browser. The non-public check reads the IANA IPv4 and IPv6 Special-Purpose Address Registries (fetched 2026-09-28), transcribed in ianadata.js. The Apache License 2.0 text ships with this app as LICENSE-Apache-2.0.txt.
