up to 200 sampling observation rows (sample_value, sample_weight) producing two reports: adjacent row change analysis and keyed dataset comparison between two supplied datasets.","exampleAgentPrompt":"Compare these two sets of sampling observations for sample_value — the first dataset has rows for group-a and group-b from Oct 1–4 2026, and the second dataset has slightly different values for the same rows — give me both an adjacent row change breakdown and a keyed comparison showing where the two datasets differ.","exampleUseCases":[{"title":"Survey wave-over-wave change detection","prompt":"I have two waves of survey data, each with up to 150 rows tagged by respondent ID, date, and group — can you run adjacent row change analysis and a keyed comparison on sample_value between wave 1 and wave 2 so I can see what shifted?"},{"title":"QA check on updated sample weight file","prompt":"Our data team just revised the sample_weight column in our sampling records — compare the original file and the updated file row by row using sample_weight as the field, and flag which row IDs changed and by how much."},{"title":"Sequential measurement drift analysis","prompt":"I have 200 rows of instrument readings over time with sample_value and sample_weight fields — run the adjacent row change report on sample_value so I can spot where readings jumped unexpectedly between consecutive dates."}],"resultDescription":"Returns two analytical reports: (1) an adjacent row change report showing value deltas between consecutive rows ordered by date/row, and
