Type a question. Watch Claude pick the right tables, write the SQL, build the charts, and deliver a ranked set of recommendations. Every tool call is visible — no black boxes. Reports are shareable, commentable, schedulable, and exportable.
The UI streams each tool call as Claude makes it — the SQL written, the row counts, the execution time. Click any step to expand the full query + preview rows. An indeterminate progress bar plus elapsed timer mean the run never looks stuck.
Claude never sees a blank SQL prompt. It composes queries via a small, typed toolbox — keeping the agent focused and the errors cheap.
list_tablesNames + row-count hints + one-liner per table. Always the first call.
describe_tableFull schema + CAVEATS + live null-rate / cardinality probe.
sampleUp to 20 raw rows for data-shape understanding. Hard-capped, not for analysis.
query_sqlRead-only SELECT / WITH only. Auto-LIMIT 10k, 30s timeout, DDL/DML rejected.
finish_reportTerminal. Emits structured report: stats, charts, tables, text, recommendations.
