Install Spring Boot Architecture

skills CLI
$ npx skills add HoangNguyen0403/agent-skills-standard --skill spring-boot-architecture -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install HoangNguyen0403/agent-skills-standard spring-boot-architecture --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/HoangNguyen0403/agent-skills-standard.git skills-src && mkdir -p .claude/skills && cp -r skills-src/skills/spring-boot/spring-boot-architecture .claude/skills/spring-boot-architecture && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

What it does

Spring Boot Architecture is an agent skill from HoangNguyen0403/agent-skills-standard. Structure Spring Boot 3+ projects with feature packaging and clean layering. Use when structuring Spring Boot 3 projects, defining layers, or applying architecture patterns.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Backend & APIs, covering Backend development. It works with Spring Boot and Java. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Structuring Spring Boot 3 projects
  • Defining layers
  • Applying architecture patterns

Example prompts

  • “/spring-boot-architecture”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Controller (Web): Handle HTTP, Validation (@Valid), DTO mapping. Delegate logic to Service.
  2. Service (Business): Transaction boundaries, orchestration. Returns Domain/DTOs.
  3. Repository (Data): Database interactions only. Returns Entities/Projections.

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spring Boot Architecture loads about 643 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 232 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~643
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Spring Boot Architecture Standards

Priority: P0 (CRITICAL)

Organize by Feature

  • Package by Feature: Prefer com.app.feature (e.g., user, order) over technical layers (controllers) for scalability.
  • Dependency Rule: Outer layers (Web) depend on Inner (Service). Inner layers MUST NOT depend on Outer.
  • DTO Pattern: ALWAYS use DTOs for API inputs/outputs. NEVER return @Entity directly.
  • Java Records: Use record for DTOs to ensure immutability (Java 17+).

See implementation examples for Java Record DTOs, controller patterns, and global exception handling.

Define Layer Responsibilities

  1. Controller (Web): Handle HTTP, Validation (@Valid), DTO mapping. Delegate logic to Service.
  2. Service (Business): Transaction boundaries, orchestration. Returns Domain/DTOs.
  3. Repository (Data): Database interactions only. Returns Entities/Projections.

Design API Layer

  • Global Error Handling: Use @RestControllerAdvice with ProblemDetails (RFC 7807).
  • Validation: Use Jakarta Bean Validation (@NotNull, @Size) on DTOs.
  • Response: Use ResponseEntity for explicit status or ResponseStatusException.

Verification Checklist (Mandatory)

  • No Entities in API: all API responses using DTOs/Records instead of JPA Entities?
  • Validation: @Valid and Jakarta Bean Validation constraints present on all input DTOs?
  • Layer coupling: Services depend on Controllers? (Prohibited)
  • Transactionality: business transactions correctly bounded with @Transactional in Service layer?
  • Error Details: ProblemDetails used for consistent error responses?

Anti-Patterns

  • No Fat Controllers: Move business logic to Services.
  • No Leaking Entities: Use DTOs instead of JPA Entities in APIs.
  • No Circular Dependencies: Use Events or refactor to decouple services.
  • No God Classes: Split large services into single-responsibility components.
