Tools are classes that an Agent uses to interact with the world.
Each tool has a description. Agent uses the description to choose the right tool for the job.
Class hierarchy:
RunnableSerializable --> BaseTool --> <name>Tool # Examples: AIPluginTool, BaseGraphQLTool
<name> # Examples: BraveSearch, HumanInputRun
Main helpers:
CallbackManagerForToolRun, AsyncCallbackManagerForToolRun
