[moving this to dev]
2. "open_project" tool is committed. If anyone has a Windows machine handy,
appreciate if you could build Modeler from master ("mvn clean verify
-Passembly,windows") and see if project opening works there.
I also added "Agentic Coding" chapter to the docs that should help with
installation and sample prompts:
https://github.com/apache/cayenne/tree/master/docs/asciidoc/cayenne-guide/src/docs/asciidoc/_cayenne-guide/part3
3. Next is the hardest tool - DB Import. It requires linking XML import config
with a Modeler-defined DataSource. So will likely need to share Modeler
preferences with the MCP Server and make the agent steer the user to
"open_project" to create new datasources and link the project to one of them.
Also, an interesting bit that I haven't fully thought through yet - smart
relationship naming. Our current naming algorithm can do simple English plurals
and that's about it. E.g., when 2 entities have more than one relationship
between them based on multiple FKs, you'd often get meaningless names like
"targets1", "targets2" (specifically for the to-many part). A model should be
able to inspect FKs and create proper phrases ("manager" -> "managedBy"). And
this can go further - we (or the users) can provide naming "skills" for a
particular style, etc. Fun stuff.
Thanks,
