senior-java

senior-java is a skill for Claude Code, Codex from xuansenpa1/skillrevise. It costs 65 tokens per session (4,462 once invoked), scanned A, a copy of senior-java, MIT.

A Java and Spring Boot development guide for enterprise applications and services. It covers project setup, database access, web APIs, security, dependency management, and performance work.

In plain words
What is it for?
Use it to scaffold Spring Boot projects, create JPA data layers and REST APIs, configure OAuth2 or JWT security, review dependencies, and profile JVM performance.
Why use it?
It provides guidance for common Spring Boot development tasks without requiring developers to assemble each project structure or configuration from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

senior-java scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/api_endpoint_generator.py, scripts/dependency_analyzer.py, scripts/entity_generator.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Senior Java

World-class Java and Spring Boot development skill for enterprise applications, microservices, and cloud-native systems. Expertise in Spring Framework, Spring Boot 3.x, Spring Cloud, JPA/Hibernate, and reactive programming with WebFlux.

Overview

This skill provides production-ready Java and Spring Boot development capabilities through six Python automation tools and comprehensive reference documentation. Whether building enterprise monoliths, microservices architectures, or reactive systems, this skill ensures best practices, scalable architecture, and enterprise-grade security.

What This Skill Provides:

  • Spring Boot project scaffolding with layered architecture
  • JPA entity and repository generation with optimized queries
  • RESTful API endpoint scaffolding with proper error handling
  • Spring Security configuration (OAuth2, JWT, RBAC)
  • Dependency analysis and upgrade recommendations
  • JVM performance profiling and optimization guidance

Use this skill when:

  • Starting new Spring Boot projects or microservices
  • Implementing JPA/Hibernate data layers
  • Designing RESTful APIs with Spring MVC or WebFlux
  • Setting up authentication and authorization
  • Optimizing JVM and application performance
  • Reviewing Java code for quality and patterns

Core Value: Save 60%+ time on project scaffolding while ensuring enterprise-grade architecture, security compliance, and performance optimization.

Core Capabilities

  • Spring Boot Scaffolding - Generate production-ready Spring Boot 3.x projects with layered architecture, Docker configuration, and CI/CD pipelines
  • Entity Generation - Create JPA entities with repositories, services, controllers, DTOs, and mappers following DDD patterns
  • API Development - Scaffold RESTful endpoints with validation, error handling, pagination, and OpenAPI documentation
  • Security Implementation - Configure Spring Security with OAuth2, JWT, role-based access control, and security best practices
  • Dependency Management - Analyze dependencies for vulnerabilities, outdated versions, and upgrade paths
  • Performance Optimization - Profile JVM applications, identify bottlenecks, and generate optimization recommendations
