  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Spring Modulith Verifier is an agent skill from sivaprasadreddy/sivalabs-agent-skills. Verifies whether code follows Spring Modulith code structure or not. Show list of violations along with recommendations on how to fix them. Use this skill: When reviewing Spring Boot applications which uses Spring Modulith When verifying whether Spring Boot application code follows Spring Modulith package structure

Its SKILL.md is about 1.7k 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. It works with Spring Boot and Java. The repository describes itself as: Spring Boot skills for AI coding agents. The licence is MIT.

When your agent uses it

  • Tasks that involve Backend development

Example prompts

  • “Use the spring-modulith-verifier skill to verify whether code follows Spring Modulith code structure or not”
  • “/spring-modulith-verifier”

What it can do on your machine

Read from SKILL.md and the folder at commit e9f9861. 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 Modulith Verifier loads about 1.7k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 425 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

Explanation of the above package structure:

  • Application.java: The main Spring Boot entry point class annotated with @SpringBootApplication. Contains the main() method that bootstraps the application.

  • shared/: Contains cross-cutting concerns and utilities shared across multiple modules (e.g., common utilities, shared DTOs, base classes, custom annotations).

  • {module}/ (e.g., users/, catalog/, orders/): Each business module represents a bounded context and contains:

    • config/: Module-specific configuration classes annotated with @Configuration for beans, properties, or third-party integrations relevant only to this module.

    • domain/: Core business logic layer containing:

      • models/: Domain model classes (Command, Query objects, Enums, Value Objects, Result objects, etc) representing business concepts (not JPA entities). These are pure Java objects that encapsulate business rules.
      • exceptions/: Domain specific custom Exception classes.
      • entities: JPA entity classes annotated with @Entity that map to database tables. These should not be public to prevent direct instantiation and ensure encapsulation.
      • repositories: Spring Data JPA repository interfaces extending JpaRepository or CrudRepository for data access. These should not be public.
      • mappers: Mapper classes/interfaces (e.g., MapStruct mappers) for converting between entities, domain models, and DTOs. These should not be public.
      • services: Service classes annotated with @Service containing business logic, converting beans using mappers, transaction management, and orchestration of repository calls.
    • api/: REST API layer containing:

      • controllers: REST controller classes annotated with @RestController that handle HTTP requests, validate input, and delegate to services.
      • DTOs: Data Transfer Objects including request payloads (data coming from clients) and response payloads (data sent to clients).
    • {Module}API.java: A facade class that serves as the module's public API, delegating calls to services, exposing only what other modules should access while hiding internal implementation details.

  • config/: Global application-wide configuration classes including:

    • WebMvcConfig.java: MVC configuration (CORS, interceptors, formatters).
    • SecurityConfig.java: Spring Security configuration for authentication and authorization.
    • GlobalExceptionHandler.java: Centralized exception handling using @RestControllerAdvice for consistent error responses.
