ToolAnnotations

Additional properties describing a Tool to clients. NOTE: all properties in ToolAnnotations are **hints**. They are not guaranteed to provide a faithful description of tool behavior (including descriptive properties like `title`). Clients should never make tool use decisions based on ToolAnnotations received from untrusted servers.
