Build Modern Java Systems
Java teams need practical guidance for modern language features, Spring Boot, and production performance. This skill gives Claude, Codex, and Claude Code focused Java architecture, testing, and optimization support.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "java-pro" from https://skillstore.io/skills/sickn33-java-pro.md and its manifest at https://skillstore.io/api/skills/sickn33-java-pro/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "java-pro". I need to migrate a high-traffic Spring service to Java 21.
Expected outcome:
A migration plan covering dependency checks, Spring Boot 3.x changes, virtual thread readiness, test coverage, rollout steps, and monitoring signals.
Using "java-pro". Our Java API has high latency during peak traffic.
Expected outcome:
A performance review plan covering profiling, garbage collection analysis, database query checks, thread model review, benchmarking, and safe tuning experiments.
Using "java-pro". We need secure OAuth2 authentication in a Spring application.
Expected outcome:
A security design outline covering Spring Security 6 configuration choices, token validation, authorization rules, error handling, tests, and operational controls.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Modernize Java Services
Plan upgrades to Java 21, Spring Boot 3.x, virtual threads, and current framework conventions.
Design Enterprise Architectures
Shape microservices, distributed tracing, resilience, security, and persistence patterns for production systems.
Improve JVM Performance
Review throughput, latency, memory, startup time, profiling, benchmarking, and GraalVM deployment options.
Try These Prompts
Help me plan this Java 21 task. Explain the best approach, key risks, tests, and verification steps.
Review this Spring Boot service upgrade to Java 21 and Spring Boot 3.x. Identify required changes, compatibility risks, and testing priorities.
Analyze this Java service performance issue. Recommend profiling steps, JVM tuning options, concurrency changes, and benchmark checks.
Design a production-ready Java microservices architecture for this domain. Include security, persistence, observability, resilience, deployment, and test strategy.
Best Practices
- Provide the Java version, Spring version, build tool, deployment target, and relevant constraints.
- Ask for tests, observability, security, and rollback guidance when changing production Java systems.
- Share representative errors, profiling results, or architecture diagrams when asking for optimization help.
Avoid
- Do not ask for broad Java advice without project goals, constraints, or runtime context.
- Do not apply virtual threads or GraalVM only because they are modern features.
- Do not skip integration tests, dependency review, or production monitoring for framework upgrades.
