CSV analyse

When to use

The user has a CSV file (uploaded, written to the filesystem, or inline) and wants a structured summary or statistical analysis.

Examples:

• "Summarise sales.csv"
• "What columns are in this file and what do they contain?"
• "Give me descriptive stats for the numeric columns"
• "Count missing values per column"

Steps

1. Locate the CSV. If the user mentioned a filename, call fs_list and fs_read under uploads/ or their chosen folder to get the content as a string. If the content is in a previous tool result or an attachment, pass it directly as stdin.
