What it does

Go Coding Standards is an agent skill from ZhangShenao/harness9. Use when writing or reviewing Go code — explains harness9 project coding conventions and patterns

Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code quality. The repository describes itself as: Local-First · 轻量级 · 功能完备 · 生产可用的通用 Agent 框架. The licence is MIT.

When your agent uses it

Tasks that involve Code quality

Example prompts

“/go-coding-standards”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

在 internal/tools/ 下创建 xxx.go，实现 BaseTool 接口
使用 safePath() 校验所有文件路径参数
在 internal/tools/xxx_test.go 中添加表驱动测试
在 cmd/harness9/main.go 中注册工具

What it can do on your machine

Read from SKILL.md and the folder at commit f73d0f1. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- go
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Go Coding Standards loads about 719 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 77 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~29
When it runs · the whole SKILL.md, loaded when a task matches: ~719

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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	`engine`、`provider`、`schema`
导出类型/函数	PascalCase	`AgentEngine`、`NewRegistry`
未导出类型/函数	camelCase	`mainLoop`、`runLoop`
接口名	以 `-er` 后缀为惯例	`Provider`、`Registry`、`BaseTool`
常量	PascalCase（导出）或 camelCase（未导出），不使用全大写	`RoleSystem`、`maxLogOutputLen`
配置选项函数	`With` 前缀	`WithMaxTurns`、`WithToolTimeout`

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

在 internal/tools/ 下创建 xxx.go，实现 BaseTool 接口
使用 safePath() 校验所有文件路径参数
在 internal/tools/xxx_test.go 中添加表驱动测试
在 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) { /* ... */ }

测试规范

使用标准库 testing 包，不引入第三方断言库
表驱动测试优先
运行：go test ./...

func TestXxx(t *testing.T) {
    cases := []struct {
        name  string
        input string
        want  string
    }{
        {"normal", "foo", "bar"},
        {"empty", "", ""},
    }
    for _, tc := range cases {
        t.Run(tc.name, func(t *testing.T) {
            got := Xxx(tc.input)
            if got != tc.want {
                t.Errorf("got %q, want %q", got, tc.want)
            }
        })
    }
}

代码检查

提交前必须通过：

bash

gofmt -l .        # 无输出表示格式正确
go vet ./...      # 无 warning
go test ./...     # 全部通过
