Seems to work when testing it out locally

Generally LGTM, but some operational notes/concerns:

• I wasn't able to "create a database" or "create an autonomous database", but describing and interacting with an existing db worked fine.
• I could only convince one model to "list all my databases" (after a confirmation):

To list “all my databases,” do you want me to include every compartment (including subcompartments) and every subscribed region, and include both Autonomous Databases and DB System databases?

• Excessive context use (large server w/ many tools)
