## Summary [#summary]

The **CSV to Questions Agent** takes a CSV dataset and turns it into a set of
sharp, answerable analytical questions. It first summarizes the data — columns,
types, ranges, patterns — to compress large files and avoid token-limit errors,
then generates questions a data analyst would actually ask. Reach for it to
kickstart exploratory analysis or build study material from raw data.

## Composition [#composition]

```text
├── config.ts            # Agent definition (model + config)
├── instructions.md      # Summarize-then-question instructions
└── tools/
    └── fetch_csv.ts     # Loads a CSV file from a URL
```

## Customization [#customization]

* **Read local files.** Swap `fetch_csv` to read from disk or object storage
  instead of a URL.
* **Control the question style.** Edit `instructions.md` to bias toward trends,
  comparisons, or hypothesis tests.
* **Swap the model.** Edit `config.ts`. A large-context model handles wide
  datasets without truncation.
* **Chunk huge files.** Summarize in row batches and merge the profiles before
  generating questions.
