Adding a widget to the catalog is a lot of work and seemingly boilerplate #528
Description
IIUC, if someone wants to add a widget to the catalog, they need to:
- specify it via JSON schema
- create a CatalogItem
- update the system prompt
That's a lot of work. What are some ways we can help make this easier?
Will code generation help? Maybe build_runner is useful here.
Could we make the JSON Schema something that a CatalogItem can generate for us?
Are their convenience or utility mechanisms to update the system prompt?
