SQLite databases

Gives every agent six tools for SQLite files (.db, .sqlite, .sqlite3):

Tool	What it does
sqlite_tables	The tables and views, with each table's row count
sqlite_schema	How a table is defined: columns, keys, indexes, foreign keys
sqlite_query	Runs a query that only reads; the file is opened read-only
sqlite_execute	Changes data or tables, in one transaction (all or nothing)
sqlite_import_csv	Loads a CSV file into a table
sqlite_export_csv	Writes a query's rows to a CSV file

It needs only Python 3, with nothing to install. The skill sqlite-databases tells agents how to work with a database carefully: look first, back up before changing, and check the result.
