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.
npx agentmods add rules/wangqiqi/cursor-ai-rules/cpp-basicsgit clone --depth 1 https://github.com/wangqiqi/cursor-ai-rulesWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.01862 |
| Opus 5 | $0.00000 | $0.00931 |
| Sonnet 5 | $0.00000 | $0.00372 |
| Haiku 4.5 | $0.00000 | $0.00186 |
Grade A, and why
cpp-basics 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.
How it starts
The opening of the file, as written. The whole thing — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.

📝 编码规范
现代C++特性使用 (C++11/14)
#include <iostream>
#include <memory>
#include <vector>
#include <string>
#include <functional>
// ✅ 推荐:使用智能指针和RAII
class FileHandler {
private:
std::unique_ptr<std::FILE, std::function<void(std::FILE*)>> file_;
public:
explicit FileHandler(const std::string& path)
: file_(std::fopen(path.c_str(), "r"),
[](std::FILE* f) { if (f) std::fclose(f); }) {
if (!file_) {
throw std::runtime_error("Failed to open file");
}
}
// 使用const std::string&避免字符串拷贝
void processLine(const std::string& line) {
std::cout << "Processing: " << line << std::endl;
}
};
// ✅ 推荐:使用auto和范围for
boost::optional<std::string> findUser(const std::vector<User>& users,
const std::string& name) {
for (const auto& user : users) {
if (user.name == name) {
return user.email;
}
}
return boost::none;
}
// ✅ 推荐:使用constexpr进行编译时计算
constexpr int fibonacci(int n) {
return (n <= 1) ? n : fibonacci(n - 1) + fibonacci(n - 2);
}
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.

cpp-basics is a cursor rule published in the GitHub repository wangqiqi/cursor-ai-rules (15 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,862 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
