What it does
Spring Boot Idioms is an agent skill from irahardianto/awesome-agv. Spring Boot 3.x framework patterns: constructor-based DI, Spring Data JPA, REST controllers with RFC 7807 error handling, Actuator observability, and slice testing. Use when building or maintaining Spring Boot microservices. Pair with java-idioms.
Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Backend development, Observability and Microservices. It works with Spring Boot and Java. The repository describes itself as: Comprehensive sets of standards and practices designed to elevate the capabilities of AI coding agents. The licence is MIT.
When your agent uses it
- Maintaining Spring Boot microservices
- Tasks that involve Backend development
- Tasks that involve Observability
Example prompts
- “/spring-boot-idioms”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Constructor injection only — never field injection
- @ConfigurationProperties over @Value for typed config.
What it can do on your machine
Read from SKILL.md and the folder at commit 9e997ba. 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 (its code samples are java).
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 Idioms loads about 794 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 145 words of instructions outside code blocks.
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.

- description
- Spring Boot 3.x framework patterns: constructor-based DI, Spring Data JPA, REST controllers with RFC 7807 error handling, Actuator observability, and slice testing. Use when building or maintaining Spring Boot microservices. Pair with java-idioms.
Spring Boot Idioms and Patterns
Spring Boot (3.x) rewards auto-configuration, constructor injection, and actuator-driven observability. Idiomatic Spring = annotation-driven, testable, production-ready.
Scope: Spring Boot-specific patterns. For Java:
@.agents/skills/java-idioms/SKILL.md.
Dependency Injection
Constructor injection only — never field injection:
java @Service public class TaskService { private final TaskRepository repository; private final TaskMapper mapper; public TaskService(TaskRepository repository, TaskMapper mapper) { this.repository = repository; this.mapper = mapper; } }@ConfigurationPropertiesover@Valuefor typed config.
Spring Data JPA
Query methods for simple queries:
java interface TaskRepository extends JpaRepository<Task, UUID> { List<Task> findByStatusOrderByCreatedAtDesc(TaskStatus status); @Query("SELECT t FROM Task t WHERE t.priority = :priority AND t.status = 'ACTIVE'") List<Task> findActivByPriority(@Param("priority") Priority priority); }Projections for read-only views — avoid loading full entities.
@Transactionalon service methods, never on repositories.
REST Controllers
@RestController+ DTOs — never expose entities directly:java @RestController @RequestMapping("/api/v1/tasks") public class TaskController { @PostMapping @ResponseStatus(HttpStatus.CREATED) public TaskResponse create(@Valid @RequestBody CreateTaskRequest request) { return taskService.create(request); } }@ControllerAdvicefor global exception handling.
Actuator and Observability
- Actuator endpoints enabled for health, metrics, info.
- Micrometer for custom metrics.
- Structured logging with MDC for correlation IDs.
Testing
For universal testing principles, see
.agents/rules/testing-strategy.md. Below: language-specific patterns only.
@SpringBootTestfor integration,@WebMvcTestfor controller slices:java @WebMvcTest(TaskController.class) class TaskControllerTest { @Autowired MockMvc mockMvc; @MockBean TaskService taskService; @Test void createTask_returns201() throws Exception { mockMvc.perform(post("/api/v1/tasks") .contentType(MediaType.APPLICATION_JSON) .content("{\"title\":\"Test\",\"priority\":\"HIGH\"}")) .andExpect(status().isCreated()); } }TestContainers for database integration tests.
