Enumerate types of objects that can be created using `create_object` tool

[saramaebee]

During the demo the other day with Ahmed, one problem they encountered was the create_object tool defaulting to issue. I think that enumerating the types of objects that can be created might help here

How do we help provide the model with information about devrev, such as knowing when it should create issue vs enhancement vs ticket? Perhaps that's where prompts come in to play as well, but I'm not sure
