protocol-buffer-definitions-rule

protocol-buffer-definitions-rule is a cursor rule for coding agents from holtwood/awesome-cursorrules-zh. It costs 74 tokens per session, scanned A, original, MIT.

Rules for editing Protocol Buffer definition files, which describe structured messages and services used between programs.

In plain words
What is it for?
Creating or changing .proto files with clear definitions, correct naming, and a suitable Go package setting.
Why use it?
They keep message design, data types, naming, and generated Go code settings consistent.

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

protocol-buffer-definitions-rule 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

在处理 .proto 文件时:

  • 定义清晰简洁的消息和服务。
  • 使用正确的数据类型和命名约定。
  • 确保为 Go 代码生成正确设置 go_package 选项。

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.
