🎯 Course Overview

Transform your Java development workflow by learning how to select, invoke, and combine Plinth's Java Agent Skills. The course uses progressive, hands-on exercises to improve Maven builds, design, testing, security, modern Java, performance, profiling, and documentation.

Rather than treating a skill as a reusable prompt fragment, each module treats it as an executable workflow with prerequisites, constraints, validation, and explicit outputs.

🎓 What You'll Learn

By the end of this course, you'll be able to:

Select the right Java skill for a concrete engineering objective
Provide the repository context and trusted inputs each skill needs
Follow interactive skill workflows without bypassing safeguards
Validate Maven, code, tests, profiling evidence, and documentation proportionally
Compose several skills into traceable delivery workflows
Distinguish generation, analysis, refactoring, and verification responsibilities

📚 Course Structure

This course is organized into 7 progressive modules:

Module 1: Foundations - Maven project setup with 110-java-maven-best-practices, 111-java-maven-dependencies, 112-java-maven-plugins, and 113-java-maven-documentation
Module 2: Code Quality - Testing and design with 131-java-testing-unit-testing, 121-java-object-oriented-design, and 122-java-type-design
Module 3: Secure and Resilient Code - Security, concurrency, logging, and exceptions with skills 124, 125, 181, and 126
Module 4: Modern Java - Generics, functional programming, data-oriented programming, and modern refactoring with skills 128 and 141-144
Module 5: Performance - Load testing and the complete Detect → Analyze → Refactor → Verify profiling lifecycle with skills 151 and 161-164
Module 6: Documentation - Project documentation and architecture diagrams with 170-java-documentation and 033-architecture-diagrams
Module 7: Skill Workflows - Skill selection, sequencing, evidence handoffs, validation, and workflow design

Total Duration: approximately 34 hours, suitable for a 4-6 week learning path.

🚀 Getting Started

Clone the repository:

git clone https://github.com/jabrena/plinth.git
cd plinth

Review the generated skills available to your agent:

find .agents/skills -mindepth 1 -maxdepth 1 -type d | sort

Start with Module 1: Foundations.
For every exercise:

State the engineering objective and relevant file scope.
Name the skill explicitly.
Answer required workflow questions.
Review proposed changes and generated evidence.
Run the validation required by the skill and repository.
