A curated collection of Rules, Skills, and Agents for Java Enterprise development, designed to streamline modern SDLC workflows.
The project add support for:
- Agile:
User Stories&Github Issues - Architecture:
ADRs&UML/C4/ERDiagrams` - Spec-Driven:
AGENTS.md,AI Plan mode&OpenSpec - Java development:
Build system based on Maven,Design,Coding,Testing,Observability,Refactoring & JMH Benchmarking,Performance testing with JMeter,Profiling with Async profiler/OpenJDK tools&Documentation - Java frameworks:
Spring Boot,Quarkus&Micronaut.
The project generates a set of deliverables at the end of any iteration.
| Deliverable | Location |

Agents
The SDLC has evolved with the arrival of this new set of AI tooling, enhancing the Software Engineering process. In the development of this project, it was identified 3 different workflows: Prompting Enginering Workflow, Pipelines Workflow & Agentic Workflow.
In this workflow, the Software engineer interact with models using User prompts and in an incremental way you delegate a delegate completely a task or ask help in certain moments. You could use this project to refactor the code generated or delegate the task and associate a System prompt / Skills to that task.
Agents for Java Enterprise development were designed to help the Software engineer in the implementation phase. The software engineer define good Specs and that Specifications are delegated to Agents.
Adding AI tools to your pipeline can provide new opportunities to deliver more value (examples: automatic coding, code refactoring, continuous profiling, and others).
From the outset, be aware that the results provided by interactions with the different Cursor rules are not deterministic due to the nature of the models, but this can be mitigated with clear goals and validation checkpoints.
Models are able to generate code, but they cannot run code with your local data. To address this limitation, some prompts provide scripts to bridge this gap on the model side.
See CONTRIBUTING.md for conventions, generator workflows, tests, and how to open a pull request.
The repository includes a collection of examples where you can explore the possibilities of these system prompts designed for Java.

- Review the CHANGELOG for further details
Java uses JEPs as the vehicle to describe new features to be added to the language. The repository continuously reviews which JEPs could improve any of the cursor rules present in this repository.
