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 | $0.00042 | $0.00414 |
| Opus 5 | $0.00021 | $0.00207 |
| Sonnet 5 | $0.00008 | $0.00083 |
| Haiku 4.5 | $0.00004 | $0.00041 |
Grade A, and why
Go开发模式 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 5d 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.
This is a copy
100% identical to Go开发模式 — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Go 开发模式
适用场景
使用 Go 语言开发后端服务、CLI 工具、微服务时。
核心原则
- 显式优于隐式——Go 不鼓励魔法，代码应该直白可读
- 错误是值——每个可能出错的地方都显式处理错误，不要忽略
- 接口小而精——接口只定义必需的方法，一个方法的接口最好
- 组合优于继承——用结构体嵌入和接口组合，不要模拟类继承
- 并发用 goroutine + channel——但不要过度并发，简单任务用同步就好
项目结构
Go 项目推荐按功能/领域组织，而非按层级：
- cmd/ 放入口文件
- internal/ 放不对外暴露的逻辑
- pkg/ 放可复用的公共包
- 每个包职责单一，包名就是它做什么
错误处理
- 返回 error 而非 panic
- 用 fmt.Errorf 包装错误添加上下文
- 在调用方处理错误，不在被调用方静默吞掉
- 对外 API 返回统一的错误结构
并发模式
- 用 context 控制 goroutine 生命周期
- 用 sync.WaitGroup 等待多个 goroutine 完成
- channel 用于通信，mutex 用于保护共享状态
- 总是处理 channel 的关闭和超时
测试
- 表驱动测试（Table-Driven Tests）是标准模式
- 用 testify 做断言
- 测试文件和被测文件同目录，以 _test.go 结尾
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开发模式 is a skill published in the GitHub repository nongjun/awesome-harness-engineering (2 stars, last pushed 5mo ago), licensed MIT. It adds 42 tokens to every session and 414 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to Go开发模式, differing in 0 lines, and is treated as a copy.
