Data and tables
What happens when the agent comes back with rows of data.
When a data source or a scrape returns rows, the chat shows a table card with the number of results and the columns, a page at a time.
CSV and JSON download the whole set. API, on some tables, shows ready-made code that fetches the same data.
The whole table is stored, and the agent can filter, sort, sum and join it without reading every row into the chat. Ask it: "which of these has the highest price?". The lookup has no charge of its own, but the step that asks for it costs like any other step.
A very large set stores only its first rows, and the card says so.
