From java-core
Explains Java code in plain language: purpose, step-by-step logic, features like streams and annotations, design patterns, and gotchas. Activates on 'explain this code' or similar queries.
npx claudepluginhub ducpm2303/claude-java-plugins --plugin java-coreThis skill is limited to using the following tools:
Explain the Java code I've selected or provided. Tailor the explanation to what the code actually does — avoid generic descriptions.
Explains complex code with high-level overviews, step-by-step walkthroughs, diagrams, and audience-adapted language for onboarding and knowledge sharing.
Explains complex code in any language with plain English line-by-line breakdowns, pattern and algorithm identification, rationale for design choices, and improvement suggestions. Use on inherited code, for reviews, or onboarding.
Detects GoF design patterns like Singleton, Builder, Decorator, Strategy in Java code (Java 8+) or recommends patterns for problems with minimal implementations.
Share bugs, ideas, or general feedback.

1. Purpose (1–3 sentences) What is this code trying to accomplish? What problem does it solve?
2. How it works — step by step Walk through the logic in plain English. For each significant block:
3. Java features used Identify and briefly explain any Java-specific features present:
@Transactional, @Override)synchronized, volatile, AtomicInteger, etc.)4. Design patterns (if present) If the code implements a recognisable design pattern (Factory, Builder, Strategy, Observer, Singleton, Repository, etc.), name it and explain how the code implements it.
5. Potential gotchas Point out anything that a reader might misunderstand or that could cause subtle bugs:
Write as if explaining to a competent developer who is new to this particular codebase. Assume familiarity with basic Java but not with the specific patterns or domain logic shown.
