**Description**: ToolKit and Tools for accessing data in a Cassandra Database primarily for Agent integration. Initially, this includes the following tools: - `cassandra_db_schema` Gathers all schema information for the connected database or a specific schema. Critical for the agent when determining actions. - `cassandra_db_select_table_data` Selects data from a specific keyspace and table. The agent can pass paramaters for a predicate and limits on the number of returned records. - `cassandra_db_query` Expiriemental alternative to `cassandra_db_select_table_data` which takes a query string completely formed by the agent instead of parameters. May be removed in future versions. Includes unit test and two notebooks to demonstrate usage. **Dependencies**: cassio **Twitter handle**: @PatrickMcFadin --------- Co-authored-by: Phil Miesle <phil.miesle@datastax.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Bagatur <baskaryan@gmail.com>
