Run comprehensive Java quality audits covering OWASP security, performance (N+1, memory, threading), and JUnit 5/Mockito/Testcontainers test generation, with automated git workflow guards for dependency and policy enforcement.
Java performance reviewer — identifies N+1 queries, memory leaks, thread safety issues, and inefficient code patterns in Java 8+ applications
Java security reviewer — deep analysis of OWASP Top 10, injection vulnerabilities, Spring Security misconfigurations, and secrets handling
Java test engineer — expert in JUnit 5, Mockito, Testcontainers, test strategy, and coverage for Java 8+ projects
Quick Java performance scan flagging N+1 queries, memory issues, threading problems, and algorithmic hotspots. Use when user asks to "check performance", "performance scan", "any N+1 queries", "performance issues", "is this efficient", or "slow code".
Quick OWASP security scan for injection risks, hardcoded secrets, weak crypto, and Spring Security misconfigs. Use when user asks to "security scan", "check for vulnerabilities", "any security issues", "OWASP check", "hardcoded secrets", or "is this secure".
Generates JUnit 5 and Mockito unit tests or Testcontainers integration tests, auto-detecting project setup. Use when user asks to "write tests", "generate tests", "add unit tests", "create test class", "test this service", or "write integration tests".
