API Contract Review audits REST endpoints for HTTP semantics, versioning, backward compatibility, and response consistency. Use it when reviewing API changes or checking controller PRs before release.

Architecture Review analyzes Java project structure at the macro level, including packages, modules, layers, and dependency direction. Use it to check organization, boundary violations, and clean or hexagonal architecture compliance.

Changelog Generator creates changelog entries from conventional git commits for Java projects. Use it when preparing a release, updating release notes, or summarizing what changed since the last version.

Clean Code helps refactor code for readability and maintainability using DRY, KISS, YAGNI, and clear naming. Use it when cleaning up code, simplifying functions, or reviewing code quality.

Concurrency Review checks Java code for thread safety, race conditions, deadlocks, and async pitfalls. Use it when reviewing multi-threaded code, CompletableFuture, @Async, or modern concurrency patterns.

Design Patterns gives Java examples for common patterns like Factory, Builder, Strategy, and Observer. Use it when implementing a pattern, designing extensible components, or refactoring rigid code.

Git Commit Messages generates conventional commit messages for Java changes. Use it after code edits or when you need a commit message for staged changes.

Issue Triage categorizes open issues as bugs, feature requests, questions, duplicates, or unclear reports, then assigns priority labels. Use it during backlog reviews and regular issue maintenance.

JPA Patterns covers JPA/Hibernate performance issues, lazy loading errors, transactions, and query fetching strategies. Use it when dealing with N+1 queries, LazyInitializationException, or entity relationship design.

Java Code Review performs systematic reviews of Java code for null safety, exception handling, concurrency, collections, and idioms. Use it when reviewing code, checking a PR, or before merging changes.

Java Migration guides upgrading Java projects between major versions such as 8, 11, 17, 21, and 25. Use it when modernizing legacy code, changing build targets, or fixing API and module-system breakages.

Logging Patterns shows how to add structured SLF4J logging in Java, including JSON output and MDC request tracing. Use it when debugging application flow or making logs easier for Claude Code to analyze.

Maven Dependency Audit checks Maven projects for outdated dependencies, version conflicts, and security vulnerabilities. Use it before releases or during routine maintenance to prioritize updates and removals.

Performance Smell Detection identifies potential Java performance smells in code such as regex compilation, boxing, stream overhead, and inefficient collection use. Use it when reviewing hot paths or measured slowdowns, and measure before changing code.

Security Audit reviews Java code for OWASP Top 10 risks, input validation, injection prevention, and secure coding. Use it when reviewing vulnerabilities, checking auth code, or preparing a release.

Solid Principles reviews Java classes against SRP, OCP, LSP, ISP, and DIP. Use it when refactoring code or checking whether a class has too many responsibilities or too many reasons to change.

Spring Boot Patterns provides best practices for controllers, services, repositories, and exception handling in Spring Boot apps. Use it when creating REST APIs, structuring projects, or reviewing Spring Boot code.

Test Quality writes maintainable Java tests with JUnit 5 and AssertJ. Use it when adding tests, improving coverage, or reviewing test classes for better structure and assertions.
