duckdb

name	duckdb
description	The duckdb cli is installed on this system and is a good choice for ad-hoc data analysis from CSV, parquet or NDJSON files. Use it when the user asks for data values in the context of a specific data file or to join multiple files together.
globs	["*.csv","*.parquet"]
allowed-tools	["Bash(duckdb:*)"]

When using duckdb for querying single files, use the DESCRIBE SELECT and, optionally, SUMMARIZE SELECT statements to understand the structure beforehand.
