progen: Spring Boot Project Generator

progen is an offline, single-binary Go CLI (https://github.com/sivaprasadreddy/progen) that scaffolds a complete, production-ready Spring Boot project: build files, Java source, tests, Docker Compose, GitHub Actions, DB migrations, security, and more.

This skill's job: turn a user's description of the app they want into a .progen.json config, fill gaps by asking the user, run progen to generate the project, and — if the user asked for anything progen can't do natively — layer that on afterward by editing the generated code.
