How it works

Ask it something hard.

📎 ai-skill-for-java.txtLOADED ✓
My Spring Boot app throws LazyInitializationException when I return an Order entity from a controller. Java 17, Boot 3.
CLAUDE · WITH THIS SKILL You get: the root cause in one sentence (lazy collection serialised after the Hibernate session closed) -> a short explanation of why returning entities from controllers triggers it -> record-based DTOs in a code block -> a transactional service method that maps the entity while the session is open -> a one-line why on avoiding open-in-view -> the single next action: rerun the failing endpoint test.

What you're actually buying

This Claude/ChatGPT skill is a Java AI pair programmer inside your daily coding work: it writes complete, compilable classes and methods for your JDK level, reviews the code you paste with findings ordered by severity, debugs stack traces down to the root cause frame, writes JUnit 5 tests with Mockito and AssertJ, and fixes broken Maven or Gradle builds with the exact pom.xml or build.gradle.kts change.

It knows modern Java idioms (records, sealed types, switch expressions, Streams, java.time, virtual threads), the JVM diagnostics tools, Spring Boot, JPA and the usual concurrency and performance traps. It is a helper in your Java work, not a job-role persona, and it does not compile or run anything itself; it hands you code and the command to verify it.

Works the same way in Claude, ChatGPT and Gemini. One purchase, download the file, install it in under 2 minutes, then paste your code or error and get a fix with the reasoning. Pairs with Henrik, Java Developer, the persona skill; this one is the helper inside Java.

Questions about this product

What does the AI Skill for Java do?+

It turns Claude or ChatGPT into a Java AI pair programmer that writes compilable Java code, reviews your classes, explains stack traces, writes JUnit 5 tests and repairs Maven or Gradle builds, always stating which JDK level the code assumes.

Does it compile or run my Java code for me?+

No. It does not execute anything. It gives you the Java code, the build file change or the diagnostic command, and tells you exactly what to run to verify the result yourself.

Which Java versions and frameworks does it cover?+

It asks which JDK you target (8, 11, 17, 21 or newer) and adjusts syntax accordingly. It covers plain Java, Spring Boot, Jakarta EE, JPA and Hibernate, Jackson, Lombok and the common testing stack around JUnit 5.

How is this different from the Java Developer role skill?+

The Java Developer role skill is a full persona for planning and architecture. This Java tool skill is the pair programmer next to you: idioms, stdlib, JVM tooling, build fixes and reviews of the code you are writing right now.
