What it does

Jpa Patterns is an agent skill from affaan-m/ECC. Patrones JPA/Hibernate para diseño de entidades, relaciones, optimización de consultas, transacciones, auditoría, indexación, paginación y pooling en Spring Boot.

Its SKILL.md is about 1.2k 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 Databases, covering ORMs and data access and Backend development. It works with Spring Boot. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

Example prompts

“Use the jpa-patterns skill to patrone JPA/Hibernate para diseño de entidades, relaciones, optimización de consultas, transacciones, auditoría…”
“/jpa-patterns”

What it can do on your machine

Read from SKILL.md and the folder at commit 4eb71d9. 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

Jpa Patterns loads about 1.2k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 302 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~44
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

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: Patrones JPA/Hibernate para diseño de entidades, relaciones, optimización de consultas, transacciones, auditoría, indexación, paginación y pooling en Spring Boot.
origin: ECC

Patrones JPA/Hibernate

Usar para modelado de datos, repositorios y ajuste de rendimiento en Spring Boot.

Cuándo Activar

Diseñar entidades JPA y mapeos de tablas
Definir relaciones (@OneToMany, @ManyToOne, @ManyToMany)
Optimizar consultas (prevención de N+1, estrategias de fetch, proyecciones)
Configurar transacciones, auditoría o soft deletes
Configurar paginación, ordenamiento o métodos de repositorio personalizados
Ajustar el connection pool (HikariCP) o caché de segundo nivel

Diseño de Entidades

java

@Entity
@Table(name = "markets", indexes = {
  @Index(name = "idx_markets_slug", columnList = "slug", unique = true)
})
@EntityListeners(AuditingEntityListener.class)
public class MarketEntity {
  @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long id;

  @Column(nullable = false, length = 200)
  private String name;

  @Column(nullable = false, unique = true, length = 120)
  private String slug;

  @Enumerated(EnumType.STRING)
  private MarketStatus status = MarketStatus.ACTIVE;

  @CreatedDate private Instant createdAt;
  @LastModifiedDate private Instant updatedAt;
}

Habilitar auditoría:

java

@Configuration
@EnableJpaAuditing
class JpaConfig {}

Relaciones y Prevención de N+1

java

@OneToMany(mappedBy = "market", cascade = CascadeType.ALL, orphanRemoval = true)
private List<PositionEntity> positions = new ArrayList<>();

Usar lazy loading por defecto; usar JOIN FETCH en consultas cuando sea necesario
Evitar EAGER en colecciones; usar proyecciones DTO para rutas de lectura

java

@Query("select m from MarketEntity m left join fetch m.positions where m.id = :id")
Optional<MarketEntity> findWithPositions(@Param("id") Long id);

Patrones de Repositorio

java

public interface MarketRepository extends JpaRepository<MarketEntity, Long> {
  Optional<MarketEntity> findBySlug(String slug);

  @Query("select m from MarketEntity m where m.status = :status")
  Page<MarketEntity> findByStatus(@Param("status") MarketStatus status, Pageable pageable);
}

Usar proyecciones para consultas ligeras:

java

public interface MarketSummary {
  Long getId();
  String getName();
  MarketStatus getStatus();
}
Page<MarketSummary> findAllBy(Pageable pageable);

Transacciones

Anotar métodos de servicio con @Transactional
Usar @Transactional(readOnly = true) para rutas de lectura y optimizar
Elegir la propagación cuidadosamente; evitar transacciones de larga duración

java

@Transactional
public Market updateStatus(Long id, MarketStatus status) {
  MarketEntity entity = repo.findById(id)
      .orElseThrow(() -> new EntityNotFoundException("Market"));
  entity.setStatus(status);
  return Market.from(entity);
}

Paginación

java

PageRequest page = PageRequest.of(pageNumber, pageSize, Sort.by("createdAt").descending());
Page<MarketEntity> markets = repo.findByStatus(MarketStatus.ACTIVE, page);

Para paginación tipo cursor, incluir id > :lastId en JPQL con ordenamiento.

Indexación y Rendimiento

Agregar índices para filtros comunes (status, slug, claves foráneas)
Usar índices compuestos que coincidan con patrones de consulta (status, created_at)
Evitar select *; proyectar solo las columnas necesarias
Escrituras en lote con saveAll y hibernate.jdbc.batch_size

Connection Pooling (HikariCP)

Propiedades recomendadas:

spring.datasource.hikari.maximum-pool-size=20
spring.datasource.hikari.minimum-idle=5
spring.datasource.hikari.connection-timeout=30000
spring.datasource.hikari.validation-timeout=5000

Para el manejo de LOB en PostgreSQL, agregar:

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

Caché

La caché de primer nivel es por EntityManager; evitar mantener entidades entre transacciones
Para entidades con muchas lecturas, considerar la caché de segundo nivel con cautela; validar la estrategia de evicción

Migraciones

Usar Flyway o Liquibase; nunca depender de auto DDL de Hibernate en producción
Mantener las migraciones idempotentes y aditivas; evitar eliminar columnas sin un plan

Pruebas de Acceso a Datos

Preferir @DataJpaTest con Testcontainers para replicar producción
Verificar la eficiencia SQL con logs: establecer logging.level.org.hibernate.SQL=DEBUG y logging.level.org.hibernate.orm.jdbc.bind=TRACE para valores de parámetros

Recuerda: Mantener las entidades ligeras, las consultas intencionales y las transacciones cortas. Prevenir N+1 con estrategias de fetch y proyecciones, e indexar para tus rutas de lectura/escritura.

Patrones JPA/Hibernate para diseño de entidades, relaciones, optimización de consultas, transacciones, auditoría, indexación, paginación y pooling en Spring Boot.

When should I use Jpa Patterns?

Jpa Patterns fits situations like: tasks that involve ORMs and data access; tasks that involve Backend development.

How do I install Jpa Patterns in Claude Code?

Run `npx skills add affaan-m/ECC --skill jpa-patterns -a claude-code`. Or copy the skill folder (docs/es/skills/jpa-patterns in affaan-m/ECC) into .claude/skills/jpa-patterns in your project. Claude Code loads it when a task matches its description.

How do I install Jpa Patterns in Codex?

Run `npx skills add affaan-m/ECC --skill jpa-patterns -a codex`. Or copy the skill folder (docs/es/skills/jpa-patterns in affaan-m/ECC) into .agents/skills/jpa-patterns in your project. Codex loads it when a task matches its description.

Can I use Jpa Patterns in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add affaan-m/ECC --skill jpa-patterns -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/jpa-patterns, .gemini/skills/jpa-patterns, .github/skills/jpa-patterns and .opencode/skills/jpa-patterns in your project.

What does Jpa Patterns need to run?

SKILL.md names no scripts, command-line tools or credentials: Jpa Patterns is instructions for the agent only.

Does Jpa Patterns access the network?

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.

Is Jpa Patterns safe to install?

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.

What licence does Jpa Patterns use?

Jpa Patterns is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Jpa Patterns use?

About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Jpa Patterns?

Skills that share tags, products or a category with Jpa Patterns: Hibernate Upgrade (benchflow-ai/skillsbench, 1.8k stars), Jpa Patterns (xu-xiang/everything-claude-code-zh, 2k stars), Java Patterns (softspark/ai-toolkit, 179 stars) and Jpa Patterns (xu-xiang/everything-claude-code-zh, 2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Jpa Patterns?

affaan-m (a GitHub user) maintains it in affaan-m/ECC, which has 276,111 GitHub stars. The repository holds 683 skills in this directory. The repository was last updated on October 10, 2026.
