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.

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 5.1 | $0.00041 | $0.00389 |
| Opus 5 | $0.00020 | $0.00195 |
| Sonnet 5 | $0.00008 | $0.00078 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
golang-idiomatic-patterns 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 12d 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 (Golang) 官方原生工程化规范
1. 错误包装与解构铁律
- 必须使用
%w包装上下文：fmt.Errorf("find user id=%d: %w", id, err)。 - 判断特定哨兵错误：必须使用
errors.Is(err, sql.ErrNoRows)，严禁err == sql.ErrNoRows。 - 类型断言自定义错误：必须使用
errors.As(err, &customErr)。
2. Context 传递与生命周期
- 函数的第一个参数始终为
ctx context.Context。 - 绝不在结构体内部存储 Context，必须随方法调用链传递。
- 所有的外部网络调用、DB 查询必须接收并响应
ctx.Done()。
3. 并发安全与 Goroutine 泄漏防护
- 启动 Goroutine 前必须明确其退出机制（通过 Context 取消或 Channel 关闭信号）。
- Channel 必须由发送方（Producer）关闭，严禁接收方关闭。
func ProcessItems(ctx context.Context, items []Item) error {
g, ctx := errgroup.WithContext(ctx)
g.SetLimit(10) // 严格限制最大并发工作协程数
for _, item := range items {
item := item // 防止闭包变量逃逸共享
g.Go(func() error {
return doWork(ctx, item)
})
}
return g.Wait()
}
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

golang-idiomatic-patterns is a skill published in the GitHub repository 2428424081cn/Skill-mcp (1 stars, last pushed 18d ago), licensed MIT. It adds 41 tokens to every session and 389 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-31.
