go-coding-standards

go-coding-standards is a skill for Claude Code, Codex from ZhangShenao/harness9. It costs 23 tokens per session (1,028 once invoked), scanned A, original, MIT.

A set of coding rules and examples for writing or reviewing Go code in the harness9 project.

In plain words
What is it for?
Use it while creating or checking Go packages, exported and private functions, error handling, interfaces, configuration options, and concurrent tool execution.
Why use it?
It gives contributors consistent rules for names, errors, interfaces, constructors, and concurrent code, reducing avoidable review and maintenance problems.

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-coding-standards 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 7d 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.

harness9 Go 编码规范

命名规范

类别 规范 示例
包名 小写、单单词、无下划线 engineproviderschema
导出类型/函数 PascalCase AgentEngineNewRegistry
未导出类型/函数 camelCase mainLooprunLoop
接口名 -er 后缀为惯例 ProviderRegistryBaseTool
常量 PascalCase(导出)或 camelCase(未导出),不使用全大写 RoleSystemmaxLogOutputLen
配置选项函数 With 前缀 WithMaxTurnsWithToolTimeout

错误处理

  • 显式检查所有 error 返回值,禁止 _ 忽略
  • 错误消息不以大写字母开头、不以句号结尾
  • 使用 fmt.Errorf("context: %w", err) 包装错误,保留错误链
// ✅ 正确
result, err := doSomething()
if err != nil {
    return fmt.Errorf("do something: %w", err)
}

// ❌ 错误
result, _ := doSomething()

构造函数

命名规范:New + 类型名

func NewReadFileTool(workDir string) *ReadFileTool {
    return &ReadFileTool{workDir: filepath.Clean(workDir)}
}

接口定义原则

接口定义在使用者侧,而非实现者侧。

// ✅ 正确:Registry 接口定义在 tools 包(使用者侧)
// internal/tools/registry.go
type Registry interface {
    Register(tool BaseTool) error
    GetAvailableTools() []schema.ToolDefinition
    Execute(ctx context.Context, call schema.ToolCall) schema.ToolResult
}

// ❌ 错误:不要在实现所在的包中定义接口

并发模式

并发工具执行使用预分配切片 + 索引写入,确保结果顺序:

// Go 1.22+ 中 for range 每次迭代已自动创建新绑定,无需手动传参捕获。
// 本项目使用 Go 1.25,以下写法是正确的:
results := make([]schema.ToolResult, len(toolCalls))
var wg sync.WaitGroup
for i, tc := range toolCalls {
    wg.Add(1)
    go func() {
        defer wg.Done()
        toolCtx, cancel := context.WithTimeout(ctx, e.toolTimeout)
        defer cancel()
        results[i] = e.registry.Execute(toolCtx, tc)
    }()
}
wg.Wait()

添加新工具的步骤

  1. internal/tools/ 下创建 xxx.go,实现 BaseTool 接口
  2. 使用 safePath() 校验所有文件路径参数
  3. internal/tools/xxx_test.go 中添加表驱动测试
  4. cmd/harness9/main.go 中注册工具
type MyTool struct {
    workDir string
}

func (t *MyTool) Name() string { return "my_tool" }
func (t *MyTool) Definition() schema.ToolDefinition { /* JSON Schema */ }
func (t *MyTool) Execute(ctx context.Context, args json.RawMessage) (string, error) { /* ... */ }

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-coding-standards is a skill published in the GitHub repository ZhangShenao/harness9 (138 stars, last pushed today), licensed MIT. It adds 23 tokens to every session and 1,028 once invoked, about $0.0001 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 2026-08-30.
