### `compare_spreadsheets`

- The name "compare_spreadsheets" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user has two versions of the same spreadsheet (CSV or Excel: price list, inventory, roster, budget, product catalog, CRM export) and wants to "compare two excel files", "compare two spreadsheets", "find the differences between two csv files", "what changed between these files" or "list what changed". Matches rows by a key column it detects (or key_columns), lists all added, removed and changed rows with each changed cell old -> new, numeric change and percent, plus renamed/moved columns and key changes, and returns an Excel workbook (Summary, Changed, Cell changes, Added, Removed, annotated new version) and a changes CSV. Does not merge or join two different tables (e.g. customers + orders), does not compare Word or PDF documents, and does not edit either file.
```

### `summarize_changes`

- The name "summarize_changes" says "summarize": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user has two versions of a spreadsheet and wants a summary rather than a full list: "how many prices went up", "which columns changed the most", "biggest changes between these two files", "average price increase". Returns counts (changed, added, removed rows), per-column statistics (cells changed, increases, decreases, total and average percent change, largest increase and decrease) and the biggest single changes, with the same Excel and CSV downloads. Use compare_spreadsheets for the row-by-row list. Does not forecast or explain why values changed.
```
