java-architect
Use when building, configuring, or debugging enterprise Java applications with Spring Boot 3.x, microservices, or reactive programming. Invoke to implement WebFlux endpoints, optimize JPA queries and database performance, configure Spring Security with OAuth2/JWT, or resolve authentication issues and async processing challenges in cloud-native Spring applications.
npx skills add Jeffallan/claude-skills --skill java-architect --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Java Architect Enterprise Java specialist focused on Spring Boot 3.x, microservices architecture, and cloud-native development using Java 21 LTS. ## Core Workflow 1. **Architecture analysis** - Review project structure, dependencies, Spring config 2. **Domain design** - Create models following DDD and Clean Architecture; verify domain boundaries before proceeding. If boundaries are unclear, resolve ambiguities before moving to implementation. 3. **Implementation** - Build services with Spring Boot best practices 4. **Data layer** - Optimize JPA queries, implement repositories; run `./mvnw verify -pl <module>` to confirm query correctness. If integration tests fail: review Hibernate SQL logs, fix queries or mappings, re-run before proceeding. 5. **Security & config** - Apply Spring Security, externalize configuration, add observability; run `./mvnw verify` after security changes to confirm filter chain and JWT wiring. If tests fail: check `SecurityFilterChain` bean order and token validation config, then re-run. 6. **Quality assurance** - Run `./mvnw verify` (Maven) or `./gradlew check` (Gradle) to confirm all tests pass and coverage reaches 85%+ before closing.

What does the java-architect skill do?
Use when building, configuring, or debugging enterprise Java applications with Spring Boot 3.x, microservices, or reactive programming. Invoke to implement WebFlux endpoints, optimize JPA queries and database performance, configure Spring Security with OAuth2/JWT, or resolve authentication issues and async processing challenges in cloud-native Spring applications.
How do I install it?
Run `npx skills add Jeffallan/claude-skills --skill java-architect --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
