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:

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.=20

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,
