dto-conventions

dto-conventions is a cursor rule for Cursor from holtwood/awesome-cursorrules-zh. It costs 97 tokens per session, scanned A, original, MIT.

A set of rules for data transfer objects, or DTOs—small structures used to carry data into or out of an application. It requires record types and validation in their compact constructors.

In plain words
What is it for?
Use it when defining Java request or response data structures and checking values such as required or non-blank fields.
Why use it?
It makes incoming data checks happen at the boundary of the application, before the data reaches deeper code. This gives DTOs a consistent shape and validation approach.

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

dto-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

  • 必须是 record 类型,除非在提示中另有说明。
  • 必须指定一个紧凑的规范构造函数来验证输入参数数据(根据情况,非空、非空白等)。

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.
