Requires bbox [west,south,east,north] WGS84 and beforeDate/afterDate (YYYY-MM-DD
Requires bbox [west,south,east,north] WGS84 and beforeDate/afterDate (YYYY-MM-DD, after later). No address input: use free locus_satellite_area_prepare first. Area 1-100 sq km; each side >=500 m; aspect <=8:1. Two dated Copernicus Sentinel-2 images, not detected change or building condition. Imagery metadata only; includeImagery:true inlines base64 PNGs (>128 KB). Private, no-store, REST-only; no charge on source failure. npx @velinussage/locus-agent-skill add.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
