restcontroller-conventions

restcontroller-conventions is a cursor rule for Cursor from toptalentcoder/Cursor-AwesomeRules. It costs 169 tokens per session, scanned A, a copy of restcontroller-conventions, CC0-1.0.

A set of rules for Java Spring REST controllers, which receive HTTP requests and return API responses. It defines route mapping, dependency injection, and error handling.

In plain words
What is it for?
Use it when creating or reviewing Spring REST endpoints, including routes, HTTP methods, injected dependencies, response objects, and exception handling.
Why use it?
It keeps controller code consistent and makes API errors follow the project's shared response format. It also reduces repeated decisions about annotations and request handling.

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 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.

Origin

This is a copy

100% identical to restcontroller-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 controller classes with @RestController.
  • Must specify class-level API routes with @RequestMapping, e.g. ("/api/user").
  • Class methods must use best practice HTTP method annotations, e.g, create = @postMapping("/create"), etc.
  • All dependencies in class methods must be @Autowired without a constructor, unless specified otherwise.
  • Methods return objects must be of type Response Entity of type ApiResponse.
  • All class method logic must be implemented in a try..catch block(s).
  • Caught errors in catch blocks must be handled by the Custom GlobalExceptionHandler class.

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.
