## What ships is configuration, not an application

The repository description is a template for Spring Boot and other staff, and the README makes the intent plain: clone it and use it to generate the app you want with Claude Code. What you get is a `pom.xml`, a `CLAUDE.md`, a README, an Apache-2.0 `LICENSE`, a `.claude/` directory full of Markdown, and a `.claude-plugin/` directory.

There is no `src/` directory. There is no application class, no controller, no test. This is worth being blunt about because the Spring Boot tag will send people looking for something that is not there. The value proposition is entirely in the `.claude/` tree, and the `pom.xml` exists to give the agent a dependency surface to reason about.

The repository topics tell you what the template expects your finished application to look like: docker, flyway, junit, jwt, kubernetes, postgres and testcontainers. Those are tags for the intended shape of the generated project, not files present in the repository. If your service does not use Flyway or Testcontainers, expect the agent to propose them.

The README also links to a post on the author's own site, which is where the detailed explanation of the template lives. That means the README is deliberately a directory listing, and the real documentation is off-repository.

## Eight agent roles covering the whole delivery chain

The `.claude/agents/` directory holds eight Markdown definitions, and together they cover a full software delivery chain rather than a narrow slice of it:

```text
code-reviewer.md
devops-engineer.md
docker-expert.md
java-architect.md
kubernetes-specialist.md
security-engineer.md
spring-boot-engineer.md
test-automator.md
```

Each of these is a role definition: a name, a remit, and instructions telling the model how to approach that class of work. The `spring-boot-engineer` and `java-architect` agents are the ones that will act most often, since they cover the framework itself and the design decisions above it. `code-reviewer` and `test-automator` overlap deliberately with them, which is the interesting part: the template expects review and testing to be separate passes rather than something the implementer does inline.

The infrastructure roles are the unusual inclusion. Having `docker-expert`, `kubernetes-specialist` and `devops-engineer` as distinct agents means a deployment concern gets prompted as a deployment concern, with its own assumptions, instead of being an afterthought appended to a feature request.

None of these files are visible in the repository listing beyond their names. Whether the definitions are any good is something you can only judge by reading them, which is a two-minute check and the right first step before adopting the template wholesale.

## Nine skills, two of them with reference libraries attached

The `.claude/skills/` directory is where the substantive content sits. There is a `README.md` and nine skills: `api-contract-review`, `clean-code`, `design-patterns`, `java-architect`, `java-code-review`, `jpa-patterns`, `logging-patterns`, `spring-boot-engineer` and `spring-boot-patterns`.

Two of them carry `references/` subdirectories, and those are what separate this from a prompt collection. `java-architect` ships five reference documents: `jpa-optimization.md`, `reactive-webflux.md`, `spring-boot-setup.md`, `spring-security.md` and `testing-patterns.md`. `spring-boot-engineer` ships five more: `cloud.md`, `data.md`, `security.md`, `testing.md` and `web.md`.

That structure matters because it splits the trigger condition from the underlying guidance. A skill file states when to reach for something; a reference file holds the detail, loaded only when relevant. For a Spring Boot project that means the WebFlux guidance is not competing for context with the JPA guidance on every turn, which is the practical difference between a skill set that stays usable on a large service and one that degrades.

The topic coverage also tells you what the author considers the hard parts of Spring Boot work: data access performance, the reactive versus blocking decision, security configuration, and testing. Those are the four areas where a generic model most often produces something plausible and wrong.

## How to actually use the template

There is no install script and no build command to run. The `pom.xml` is there for the agent to read, not for you to compile. The intended workflow, in the README's own framing, is: clone the repository somewhere permanent, open it with Claude Code, and describe the application you want.

```bash
git clone https://github.com/piomin/claude-ai-spring-boot.git
cd claude-ai-spring-boot
```

Inside the project, `CLAUDE.md` is the persistent instruction file that gets loaded into context each session, and `.claude/settings.local.json` holds local settings. Both are ordinary Claude Code conventions, so the template relies on your client supporting that directory layout rather than shipping anything proprietary.

The `.claude-plugin/` directory in the tree is the one unexplained element. That path is the convention for packaging a Claude Code plugin, which would allow distribution through a marketplace rather than by cloning. The README does not mention it at all, so do not assume the template is publishable as a plugin without checking whether that directory actually holds a manifest.

A sensible adoption path is to clone it, read `CLAUDE.md` to see what the template instructs by default, then delete the agents and skills your team does not want. A template that prescribes a DevOps agent when you deploy from a different platform is a template you will spend time fighting.

## What you have to supply, and what the template will not notice

Because the repository contains no application code, everything that makes a Spring Boot project real is absent by design. There is no database schema, no Flyway migration baseline, no Dockerfile, no Kubernetes manifest, no CI workflow and no test fixture. The repository topics name those technologies, so the agent will propose them, but it has nothing to align with.

That has a specific failure mode. The generated project will look plausible and will compile, and you will discover the gaps when you try to deploy it. Establishing the connection pooling configuration, the migration baseline and the JWT issuer are decisions with no correct default, and a template cannot make them for you.

Licensing is unambiguous here, which is unusual enough to note. The repository records the Apache-2.0 licence, `LICENSE` is present at the top level, and Apache-2.0 is a permissive licence with an explicit patent grant. This article does not give legal advice; the practical point is that you can fork this into an internal repository and modify the agent definitions without worrying about copyleft obligations.

One maintenance detail: the repository has no tagged releases, so there is no version to pin and no changelog to read. The last push was on 2026-04-29, so a clone taken now reflects that point in time and nothing marks how to move forward when the agent definitions change.

## Conclusion

This template is worth cloning if you build Spring Boot services with Claude Code and want the agents and skills already written, because the reference material on JPA optimisation, reactive WebFlux, Spring Security and testing patterns is the part you would otherwise write yourself. It is not a starter application, and treating it as one will waste an afternoon. What ships is a `pom.xml`, a `CLAUDE.md`, a settings file and a directory of Markdown definitions, with no source tree and no Docker or Kubernetes manifests despite those being repository topics. Two things to verify first. The `.claude-plugin/` directory appears in the tree but the README never explains it, so check whether your client expects a plugin manifest before relying on `Load unpacked`. And the README is a directory listing plus a link to the author's own post, with no version releases, so there is no upgrade path to follow. Start by reading `CLAUDE.md`, then open `.claude/agents/spring-boot-engineer.md` and `.claude/skills/spring-boot-engineer/SKILL.md` to judge whether the instructions match how your team actually works.

## FAQ

### Is there a Claude skill available for Java?

This template bundles nine, including `java-architect`, `java-code-review`, `design-patterns`, `jpa-patterns` and `spring-boot-engineer`. Two of them attach reference libraries: `java-architect` carries guidance on JPA optimisation, reactive WebFlux, Spring Security and testing patterns, and `spring-boot-engineer` carries cloud, data, security, testing and web references.

### Can we use AI in Spring Boot?

That is the template's premise. It provides eight agent roles covering Java architecture, Spring Boot engineering, code review, testing, security, Docker, Kubernetes and DevOps, plus a CLAUDE.md, so the model works from written roles rather than from a blank prompt. The repository ships no application code, only those definitions and a pom.xml.

### Does the claude-ai-spring-boot template include a working Spring Boot application?

No. There is no source directory and no application class. The repository holds a `pom.xml`, a `CLAUDE.md`, a settings file, eight agent definitions and nine skills, and the stated workflow is to clone it and describe the application you want to generate.

### What licence is claude-ai-spring-boot released under?

Apache-2.0. The repository records that licence, a `LICENSE` file is present at the top level, and Apache-2.0 is permissive with an explicit patent grant, so the agent definitions can be forked and modified internally.
