Yeah I mean for many real world scale datasets you don’t want to blow the whole context window on a massive markdown file. Instead you can provide a tool that presents the data as a SQLite database. In my testing Claude code seems very capable of answering questions via SQLite queries or even `head` and `grep` on CSV files.
But the result from the SQL query is going to be... a table. So at some point, tables need to go into context, and we need to know how well LLMs can incorporate those tables.
