entity

A set of Java entity-development rules based on an example entity class. Java entities are classes whose fields are stored as database records through JPA.

In plain words
What is it for?
Guiding entity inheritance, class and field naming, database-table mapping, enum annotations, relationship annotations, and restrictions such as not using `@Builder` on entities.
Why use it?
Inconsistent entity names, inherited fields, annotations, or enum storage can create database and maintenance problems. These rules define the project’s expected conventions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 458 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

entity scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Entity Development Guidelines

For an example of an Entity class, refer to the Reop entity (src/main/java/com/mzfuture/entire/gitrepo/entity/Reop.java).

1. Basic Requirements

All Entity classes must inherit from BaseEntity. The BaseEntity already defines several common fields: id, createdAt, and updatedAt.

2. Naming Conventions

2.1. Class Name and Table Name

  • Entity class names must be singular business nouns, such as Reop.
  • In most cases, @Table is not required. The default JPA naming strategy will automatically map the class name to a lowercase table name separated by underscores. For example, the class name PushReviewLog will be automatically mapped to push_review_log.

2.2. Field Names

  • Field names must follow Java naming conventions (lowerCamelCase).
  • Normally, the @Column annotation should not be used. Let JPA automatically map the field names according to the naming strategy.

3. Annotation Guidelines

  • The @Builder annotation is not allowed in Entity classes.
  • For enum types, the annotation @Enumerated(EnumType.STRING) must be used. Using ORDINAL is strictly prohibited.
  • JPA relationship annotations such as @ManyToOne, @OneToMany, @OneToOne, and @ManyToMany are not allowed.
  • Avoid using @Table and @Column annotations unless absolutely necessary.

4. Commenting Guidelines

  • Both class names and field names must include comments.

5. Behavioral Guidelines

  • Simple domain behaviors are allowed, such as isActive() and getFullName().
  • The following behaviors are prohibited:
    • Business process logic
    • Calling Repository, Service, or other external components

6. Migration Guidelines

  • When creating or modifying an Entity class, a corresponding Migration script must also be created.
  • Migration scripts must follow the Migration Script Guidelines.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

entity is a cursor rule published in the GitHub repository sunmh207/entire-dashboard (24 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 458 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
