What it does

Jpa Hibernate Optimization is an agent skill from Hack23/cia. Optimize JPA/Hibernate: entity design, query performance, N+1 prevention, caching strategies

Its SKILL.md is about 530 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, Query optimization and Database schema design. The repository describes itself as: Citizen Intelligence Agency. Open-source intelligence platform analyzing Swedish political activities using AI and data visualization. Tracks politicians, government… The licence is Apache-2.0.

Example prompts

“/jpa-hibernate-optimization”

What it can do on your machine

Read from SKILL.md and the folder at commit 6a9797b. 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 and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- hibernate.org
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 Hibernate Optimization loads about 531 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 39 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~30
When it runs · the whole SKILL.md, loaded when a task matches: ~531

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.

JPA/Hibernate Optimization Skill

Purpose

Optimize database access with proper entity design, query optimization, and caching.

When to Use

✅ Designing entity relationships
✅ Optimizing slow queries
✅ Preventing N+1 queries
✅ Implementing caching

Entity Optimization

java

@Entity
@Table(name = "politician", indexes = {
    @Index(name = "idx_politician_party", columnList = "party"),
    @Index(name = "idx_politician_district", columnList = "district")
})
@Cacheable
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Politician {
    @Id
    private String id;
    
    @Column(name = "first_name", nullable = false, length = 50)
    private String firstName;
    
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "party_id")
    private Party party;
    
    @OneToMany(mappedBy = "politician", cascade = CascadeType.ALL, orphanRemoval = true)
    @BatchSize(size = 20)
    private List<VotingRecord> votingRecords;
}

Query Optimization

java

// Use JOIN FETCH to prevent N+1
@Query("SELECT p FROM Politician p JOIN FETCH p.party WHERE p.district = :district")
List<Politician> findByDistrictWithParty(@Param("district") String district);

// Use DTOs for read-only queries
@Query("SELECT new com.hack23.cia.dto.PoliticianSummary(p.id, p.firstName, p.lastName) " +
       "FROM Politician p WHERE p.active = true")
List<PoliticianSummary> findActivePoliticiansSummary();

// Pagination for large result sets
Page<Politician> findByParty(String party, Pageable pageable);

Second-Level Cache

yaml

spring:
  jpa:
    properties:
      hibernate:
        cache:
          use_second_level_cache: true
          region:
            factory_class: org.hibernate.cache.jcache.JCacheRegionFactory
        javax:
          cache:
            provider: org.ehcache.jsr107.EhcacheCachingProvider
