This skill should be used when the user asks to "compare these two GIS datasets", "what changed between this cadastre version and that one", "diff these shapefiles", "find added or removed parcels", "before and after comparison", "what features moved", or invokes `/gis-to-db:analyze-diff`. Compares two GIS layers — typically two versions of the same dataset over time — and reports added features, removed features, geometry changes (movement, area drift), and attribute changes per feature. Matches features by an attribute key (e.g. `parcel_id`) or by geometric proximity when no key is supplied.
