A set of rules for Spring Data repositories, which are interfaces that access application data. It specifies JpaRepository, JPQL queries, DTOs, and EntityGraph settings for related records.

In plain words
What is it for?
Use it when creating repository interfaces, writing JPQL joins, loading related entities, or returning data from multi-table queries.
Why use it?

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

repository-class-conventions 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 9d 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

  • 必须使用 @Repository 注解仓库类。
  • 仓库类必须是接口类型。
  • 必须继承 JpaRepository,并将实体和实体 ID 作为参数,除非在提示中另有说明。
  • 所有 @Query 类型的方法必须使用 JPQL,除非在提示中另有说明。
  • 在关系查询中必须使用 @EntityGraph(attributePaths={"relatedEntity"}) 以避免 N+1 问题。
  • 对于使用 @Query 的多表连接查询,必须使用 DTO 作为数据容器。

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.
