Spring Boot Engineer Skill for Claude Code: What It Does and How to Install It

Makes Claude build Spring Boot 3.x services with a fixed workflow: design, implement, secure, test and check health.

This skill gives Claude a six-step routine for Spring Boot work: analyze requirements, design, implement, secure, test and deploy checks. It also carries starter code for an entity, repository, service, controller, DTO, exception handler and test slice, plus rules such as constructor injection and input validation on every mutating endpoint.

It loads when you ask about Spring Boot, Spring Security, Spring Data JPA, WebFlux or Spring Cloud. Its test step tells Claude to run ./mvnw test or ./gradlew test in your project, so it needs a Maven or Gradle project on your machine. The folder bundles 5 reference guides and no scripts.

Good for

Java developers building Spring Boot 3.x REST APIs or microservices
Teams adding Spring Security 6, OAuth2 or JWT to a Spring app
Developers setting up Spring Data JPA repositories and transactions

Install spring-boot-engineer

Claude Code

Copy this prompt.

Install the spring-boot-engineer skill in Claude Code. Run this command:

/plugin marketplace add jeffallan/claude-skills
/plugin install fullstack-dev-skills@fullstack-dev-skills

Then check that it loaded and tell me how to use it.

2
Paste it into Claude Code. It shows the change and asks before running it.

Pick one route. The plugin route installs the whole fullstack-dev-skills plugin (67 skill folders and 10 command files in the repo tree, no hooks or MCP config); the skills CLI and folder routes install only spring-boot-engineer. The skill tells Claude to run ./mvnw test or ./gradlew test, so there is no Claude app upload route.

What's in the skill

When it loads

Generates Spring Boot 3.x configurations, creates REST controllers, implements Spring Security 6 authentication flows, sets up Spring Data JPA repositories, and configures reactive WebFlux endpoints. Use when building Spring Boot 3.x applications, microservices, or reactive Java applications; invoke for Spring Data JPA, Spring Security 6, WebFlux, Spring Cloud integration, Java REST API design, or Microservices Java architecture.

What it includes

Identifies service boundaries, APIs, data models and security needs.
Read · 1. Analyze requirements
Plans services, data access, cloud and security, and confirms the design before coding.
2. Design architecture
Writes services with constructor injection and a layered structure.
Starter code in SKILL.md covers an entity, repository, service, REST controller, DTO record, global exception handler and a test slice.
Try: “Add a products endpoint with search and validation to my Spring Boot app”
Write · 3. Implement
Adds Spring Security, OAuth2 and CORS, then checks the rules compile and pass tests.
Runs code · 4. Secure
Writes unit, integration and slice tests, then runs ./mvnw test or ./gradlew test.
Runs code · 5. Test
Configures Actuator health checks and validates /actuator/health returns UP.
Write · 6. Deploy checks
Five guides loaded on demand: web, data, security, cloud and testing.
Files: references/web.md, data.md, security.md, cloud.md and testing.md.
Read · Reference guides
Constructor injection, input validation, typed config, no secrets in properties files.
Bans field injection, mixing blocking and reactive code, and deprecated Spring Boot 2.x patterns such as WebSecurityConfigurerAdapter.
Rules (7 must do, 7 must not do)

Watch out for

It runs your project build and tests
SKILL.md tells Claude to run ./mvnw test or ./gradlew test and re-run after failures. Those commands run whatever your build and tests do, so use a branch and review changes first. github.com
It edits security code
The Secure step adds Spring Security, OAuth2 and CORS configuration. Review authentication and authorization changes yourself before you deploy. github.com
The plugin route adds 67 skills and 10 commands
The plugin branch tree has 67 skill folders and 10 command .md files; the marketplace description says 9 project workflow commands. We saw no hooks, agents or MCP config files in that tree. The skills CLI and folder routes install only this skill. github.com

Technical details

Turning on read-only	No read-only mode. The skill writes code and runs tests in your project.
Sign-in and keys	SKILL.md says to keep secrets in environment variables or Spring Cloud Config and never in application.properties.
Scopes	Writes Java code, configuration and tests into your project Runs ./mvnw test or ./gradlew test in your project

Questions

What does the Spring Boot Engineer skill do?

It makes Claude follow a six-step routine for Spring Boot 3.x work: analyze, design, implement, secure, test and check health. It covers REST controllers, Spring Security 6, Spring Data JPA, WebFlux and Spring Cloud.

How do I install it in Claude Code?

Use the install box at the top of this page. The repo documents a plugin route that installs the whole fullstack-dev-skills set, and the skills CLI or a folder copy installs only this skill.

Does it work in the Claude app?

The install box has no Claude app upload route. SKILL.md tells Claude to run ./mvnw test or ./gradlew test in your project, which needs a local Maven or Gradle project.

Does it need an API key?

SKILL.md names no API key. It bundles no scripts, only SKILL.md and 5 reference guides.

Is it safe?

It writes code into your project and runs your test command. Run it on a branch, read the security changes before you merge, and check that your tests do not touch real data.

Which Spring versions does it target?

Spring Boot 3.x and Spring Security 6. Its rules say not to use deprecated Spring Boot 2.x patterns such as WebSecurityConfigurerAdapter.

Does it need the other skills it lists?

No. SKILL.md lists java-architect, database-optimizer, microservices-architect and devops-engineer as related skills, but nothing in it calls them.
