# Build Better Spring Boot Applications

Spring Boot projects can become inconsistent across architecture, configuration, data access, and testing. This skill provides focused practices for maintainable Java applications.

## Capabilities

- Recommends Maven or Gradle setup, Spring starters, and feature-based package organization.
- Guides constructor injection, immutable dependency fields, and correct Spring component stereotypes.
- Covers externalized configuration, typed properties, profiles, and secret management.
- Explains REST controllers, DTO validation, consistent errors, service boundaries, and transactions.
- Provides Spring Data JPA guidance for repositories, queries, and DTO projections.
- Recommends structured logging, focused tests, Spring Security, password hashing, and input protection.

## Use Cases

- Plan a New Service: Choose a clear project structure, dependency injection approach, configuration strategy, and testing scope before implementation.
- Review an Existing API: Check controllers, DTOs, services, repositories, transactions, logging, and validation against consistent practices.
- Standardize Team Practices: Create shared review criteria for architecture, configuration, persistence, testing, and application security.

## Prompt Templates

### Start a Spring Boot Project

```
Recommend a Spring Boot structure for [service purpose]. Include build tooling, starters, packages, configuration, and an initial testing plan.
```

### Review a REST Feature

```
Review my [feature] design across controller, DTO, validation, service, transaction, and repository boundaries. Identify specific improvements.
```

### Improve Data and Tests

```
Assess my persistence and test strategy for [workflow]. Recommend repositories, queries, projections, unit tests, test slices, and integration tests.
```

### Audit Application Architecture

```
Audit this Spring Boot architecture for maintainability and security: [architecture summary]. Prioritize findings and explain practical remediation steps.
```

## Limitations

- Provides guidance only and does not create, modify, build, or run project files.
- Does not select compatible framework, plugin, or dependency versions for a specific project.
- Does not cover deployment platforms, production observability, or detailed performance tuning.
- Recommendations require adaptation to each application domain, team standard, and security policy.

## Best Practices

- Provide the application purpose, current structure, and relevant constraints.
- Share one feature or architectural concern at a time for focused guidance.
- Validate recommendations against project versions, organizational standards, and threat models.

## Anti Patterns

- Do not request generic advice without describing the service or current design.
- Do not expose secrets, credentials, personal data, or production configuration in prompts.
- Do not apply every recommendation without checking domain and compatibility requirements.

## Security Audit

- Audited at: 2026-07-23T18:04:15.96\+00:00
- Summary: All 18 static findings are false positives caused by Markdown inline-code backticks around Spring Boot names and Java examples. SKILL.md contains guidance only, with no shell execution, prompt injection, data exfiltration, or other semantic security concern.
