restcontroller-conventions

restcontroller-conventions is a cursor rule for coding agents from holtwood/awesome-cursorrules-zh. It costs 206 tokens per session, scanned A, original, MIT.

A set of rules for building REST controllers in Spring Boot. REST controllers expose web API endpoints, and the rules cover routes, HTTP methods, dependency injection, responses, and errors.

In plain words
What is it for?
Use it when adding or reviewing GET, POST, PUT, and DELETE endpoints for resources such as users or orders.
Why use it?
It removes uncertainty about how API endpoints should be named, structured, and returned. It also standardizes how failures are caught and handled.

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.

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

restcontroller-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 4d 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 @RestController 注解控制器类。
  • 必须使用 @RequestMapping 指定类级别的 API 路由,例如 ("/api/user")。
  • 使用 @GetMapping 获取,@PostMapping 创建,@PutMapping 更新,@DeleteMapping 删除。保持路径基于资源(例如 '/users/{id}'),避免使用动词。
  • 类方法中的所有依赖必须使用 @Autowired(无构造函数),除非另有说明。
  • 方法的返回对象必须是 ApiResponse 类型的 ResponseEntity。
  • 所有类方法的逻辑必须在 try..catch 块中实现。
  • catch 块中捕获的错误必须由自定义的 GlobalExceptionHandler 类处理。

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.
