repository-class-conventions is a cursor rule for Cursor from paulpham157/paul-s-cursor-rules. It costs 0 tokens per session (149 once invoked), scanned A, original, MIT.

Java repository rules for Spring Data JPA classes, which provide the code used to read and write database records. They specify JpaRepository, JPQL queries, data-transfer objects, and EntityGraphs for related data.

In plain words
What is it for?
Use them when creating repository interfaces, writing database queries, or loading records with related data in a Spring application.
Why use it?
They keep database access consistent and help avoid the N+1 problem, where one request causes many unnecessary database 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 5d 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


description: Governs the structure and functionality of repository classes, emphasizing the use of JpaRepository, JPQL queries, and EntityGraphs to prevent N+1 problems. globs: **/src/main/java/com/example/repositories/*.java

  • 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.
