Use this agent when the user has recently written or modified code and wants feedback on code quality, design, potential bugs, or architectural improvements. This agent should be invoked proactively after logical chunks of work are completed, such as: **Example 1:** user: "I've just implemented the book rating feature with controller, service, and repository layers" assistant: "Let me use the code-reviewer agent to review your implementation for code quality, potential bugs, and architectural alignment with the project standards." **Example 2:** user: "Here's my new UserService class with authentication logic" assistant: "I'll invoke the code-reviewer agent to analyze your UserService implementation and provide feedback on security, design patterns, and adherence to project conventions." **Example 3:** user: "I've added pagination to the book list endpoint" assistant: "Let me use the code-reviewer agent to review your pagination implementation and ensure it follows best practices and project standards." **Example 4:** user: "Can you look over the code I just wrote?" assistant: "I'll use the code-reviewer agent to perform a thorough review of your recent changes." Do NOT use this agent for reviewing the entire codebase unless explicitly requested. Focus on recently written or modified code.

Use this skill when asked to perform any of the following actions in a Java project: - To add jspecify support - To prevent NullPointerExceptions - To better handle Nullability This skill will add jspecify dependency, configure Maven or Gradle build to automatically use jspecify for checking Nullability issues.

Build Spring Boot 4.x applications following the best practices. Use this skill: * When developing Spring Boot applications using Spring MVC, Spring Data JPA, Spring Modulith, Spring Security * To create recommended Spring Boot package structure * To implement REST APIs, entities/repositories, service layer, modular monoliths * To use Thymeleaf view templates for building web applications * To write tests for REST APIs and Web applications * To write ArchUnit tests for testing architecture * To configure the recommended plugins and configurations to improve code quality, and testing while using Maven. * To use Spring Boot's Docker Compose support for local development * To create Taskfile for easier execution of common tasks while working with a Spring Boot application
