repository-class-conventions

repository-class-conventions is a cursor rule for Cursor from toptalentcoder/Cursor-AwesomeRules. It costs 149 tokens per session, scanned A, a copy of repository-class-conventions, CC0-1.0.

A set of rules for Java Spring Data repository interfaces, which provide an application’s database access methods. It standardizes JpaRepository usage, JPQL queries, related-data loading, and DTOs for multi-table results.

In plain words
What is it for?
Use it when defining repositories, writing JPQL queries, loading related entities, or returning data from several joined tables.
Why use it?
It helps keep database access consistent and avoids the N+1 problem, where one query unexpectedly causes many extra queries.

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 3d 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.

Origin

This is a copy

100% identical to repository-class-conventions — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

  • Must annotate repository classes with @Repository.
  • Repository classes must be of type interface.
  • Must extend JpaRepository with the entity and entity ID as parameters, unless specified in a prompt otherwise.
  • Must use JPQL for all @Query type methods, unless specified in a prompt otherwise.
  • Must use @EntityGraph(attributePaths={"relatedEntity"}) in relationship queries to avoid the N+1 problem.
  • Must use a DTO as The data container for multi-join queries with @Query.

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.
