Go安全规范

A set of Go programming rules written in Chinese that covers secret handling, security scanning, and timeout control with contexts.

In plain words
What is it for?
Use it when writing or reviewing Go code that handles credentials, needs static security checks with gosec, or performs time-limited operations.
Why use it?
It helps keep API keys out of source code, find common security issues, and prevent operations from running without time limits.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 170 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

Go安全规范 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 3d 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

Go 安全

本文件以 Go 特定内容扩展通用安全规则。

密钥管理

apiKey := os.Getenv("OPENAI_API_KEY")
if apiKey == "" {
    log.Fatal("OPENAI_API_KEY 未配置")
}

安全扫描

  • 使用 gosec 进行静态安全分析:
    gosec ./...
    

Context 与超时

始终使用 context.Context 进行超时控制:

ctx, cancel := context.WithTimeout(ctx, 5*time.Second)
defer cancel()
Changes

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.

Go安全规范 is a cursor rule published in the GitHub repository nongjun/feishu-cursor-claw (14 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 170 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.
