offline with no external lookups.","exampleAgentPrompt":"I have two sets of elevation sample readings — the main dataset and a comparison dataset, each with up to 50 rows including elevation_m and sample_weight values — can you run a two-measure correlation between elevation_m and sample_weight and then compare the two datasets row by row using the row_id as the key?","exampleUseCases":[{"title":"Pre/post survey elevation drift check","prompt":"I collected elevation samples at 30 stations before and after a construction project, each row has a row_id,

surveys?"},{"title":"Weighted elevation correlation for research","prompt":"Here are 120 rows of elevation sample measurements with elevation_m and sample_weight fields — I need to know how strongly elevation correlates with the sample weight, and I also have a second reference dataset I want to compare them against key by key using row_id."},{"title":"Multi-group station data
