What it does

Kotlin Springboot is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Get best practices for developing applications with Spring Boot and Kotlin.

Its SKILL.md is about 1.1k 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 Mobile, covering Android development and Backend development. It works with Kotlin and Spring Boot. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

When your agent uses it

  • Tasks that involve Android development
  • Tasks that involve Backend development

Example prompts

  • “/kotlin-springboot”

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. 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 kotlin).

    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

Kotlin Springboot loads about 1.1k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 496 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~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 with Kotlin Best Practices

Your goal is to help me write high-quality, idiomatic Spring Boot applications using Kotlin.

Project Setup & Structure

  • Build Tool: Use Maven (pom.xml) or Gradle (build.gradle) with the Kotlin plugins (kotlin-maven-plugin or org.jetbrains.kotlin.jvm).
  • Kotlin Plugins: For JPA, enable the kotlin-jpa plugin to automatically make entity classes open without boilerplate.
  • Starters: Use Spring Boot starters (e.g., spring-boot-starter-web, spring-boot-starter-data-jpa) as usual.
  • Package Structure: Organize code by feature/domain (e.g., com.example.app.order, com.example.app.user) rather than by layer.

Dependency Injection & Components

  • Primary Constructors: Always use the primary constructor for required dependency injection. It's the most idiomatic and concise approach in Kotlin.
  • Immutability: Declare dependencies as private val in the primary constructor. Prefer val over var everywhere to promote immutability.
  • Component Stereotypes: Use @Service, @Repository, and @RestController annotations just as you would in Java.

Configuration

  • Externalized Configuration: Use application.yml for its readability and hierarchical structure.
  • Type-Safe Properties: Use @ConfigurationProperties with data class to create immutable, type-safe configuration objects.
  • Profiles: Use Spring Profiles (application-dev.yml, application-prod.yml) to manage environment-specific configurations.
  • Secrets Management: Never hardcode secrets. Use environment variables or a dedicated secret management tool like HashiCorp Vault or AWS Secrets Manager.

Web Layer (Controllers)

  • RESTful APIs: Design clear and consistent RESTful endpoints.
  • Data Classes for DTOs: Use Kotlin data class for all DTOs. This provides equals(), hashCode(), toString(), and copy() for free and promotes immutability.
  • Validation: Use Java Bean Validation (JSR 380) with annotations (@Valid, @NotNull, @Size) on your DTO data classes.
  • Error Handling: Implement a global exception handler using @ControllerAdvice and @ExceptionHandler for consistent error responses.

Service Layer

  • Business Logic: Encapsulate business logic within @Service classes.
  • Statelessness: Services should be stateless.
  • Transaction Management: Use @Transactional on service methods. In Kotlin, this can be applied to class or function level.

Data Layer (Repositories)

  • JPA Entities: Define entities as classes. Remember they must be open. It's highly recommended to use the kotlin-jpa compiler plugin to handle this automatically.
  • Null Safety: Leverage Kotlin's null-safety (?) to clearly define which entity fields are optional or required at the type level.
  • Spring Data JPA: Use Spring Data JPA repositories by extending JpaRepository or CrudRepository.
  • Coroutines: For reactive applications, leverage Spring Boot's support for Kotlin Coroutines in the data layer.

Logging

  • Companion Object Logger: The idiomatic way to declare a logger is in a companion object.
    kotlin
    companion object {
    private val logger = LoggerFactory.getLogger(MyClass::class.java)
}
  • Parameterized Logging: Use parameterized messages (logger.info("Processing user {}...", userId)) for performance and clarity.

Testing

  • JUnit 5: JUnit 5 is the default and works seamlessly with Kotlin.
  • Idiomatic Testing Libraries: For more fluent and idiomatic tests, consider using Kotest for assertions and MockK for mocking. They are designed for Kotlin and offer a more expressive syntax.
  • Test Slices: Use test slice annotations like @WebMvcTest or @DataJpaTest to test specific parts of the application.
  • Testcontainers: Use Testcontainers for reliable integration tests with real databases, message brokers, etc.

Coroutines & Asynchronous Programming

  • suspend functions: For non-blocking asynchronous code, use suspend functions in your controllers and services. Spring Boot has excellent support for coroutines.
  • Structured Concurrency: Use coroutineScope or supervisorScope to manage the lifecycle of coroutines.
