spring-modulith-verifierVerifies whether code follows Spring Modulith code structure or not.
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.
Read from SKILL.md and the folder at commit e9f9861. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
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.
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.
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.

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:
@Entity that map to database tables. These should not be public to prevent direct instantiation and ensure encapsulation.JpaRepository or CrudRepository for data access. These should not be public.public.@Service containing business logic, converting beans using mappers, transaction management, and orchestration of repository calls.api/: REST API layer containing:
@RestController that handle HTTP requests, validate input, and delegate to services.{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:
@RestControllerAdvice for consistent error responses.Default to minimum necessary visibility. Only expose what other modules or layers genuinely need.

Verifies whether code follows Spring Modulith code structure or not. Spring Modulith Verifier is an agent skill from sivaprasadreddy/sivalabs-agent-skills. Verifies whether code follows Spring Modulith code structure or not.
Spring Modulith Verifier fits situations like: tasks that involve Backend development.
Run `npx skills add sivaprasadreddy/sivalabs-agent-skills --skill spring-modulith-verifier -a claude-code`. Or copy the skill folder (skills/spring-modulith-verifier in sivaprasadreddy/sivalabs-agent-skills) into .claude/skills/spring-modulith-verifier in your project. Claude Code loads it when a task matches its description.
Run `npx skills add sivaprasadreddy/sivalabs-agent-skills --skill spring-modulith-verifier -a codex`. Or copy the skill folder (skills/spring-modulith-verifier in sivaprasadreddy/sivalabs-agent-skills) into .agents/skills/spring-modulith-verifier in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add sivaprasadreddy/sivalabs-agent-skills --skill spring-modulith-verifier -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/spring-modulith-verifier, .gemini/skills/spring-modulith-verifier, .github/skills/spring-modulith-verifier and .opencode/skills/spring-modulith-verifier in your project.
SKILL.md names no scripts, command-line tools or credentials: Spring Modulith Verifier is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Spring Modulith Verifier is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Spring Modulith Verifier: Spring Boot (piomin/claude-ai-spring-boot, 1.3k stars), Dr Jskill (jdubois/dr-jskill, 342 stars), WxJava Integration Guide (binarywang/WxJava, 33k stars) and Flycms Dev (sunkaifei/FlyCms, 656 stars).
