+description: 逐步修复Go构建错误、go vet警告和linter问题。调用go-build-resolver代理进行最小化、精确的修复。
+---
+
+# Go 构建与修复
+
+此命令调用 **go-build-resolver** 代理，以最小的更改增量修复 Go 构建错误。
+
+## 此命令的作用
+
+1. **运行诊断**：执行 `go build`、`go vet`、`staticcheck`
+2. **解析错误**：按文件分组并按严重性排序
+3. **增量修复**：一次修复一个错误
+4. **验证每次修复**：每次更改后重新运行构建
+5. **报告摘要**：显示已修复的内容和剩余问题
+
+## 何时使用
+
+在以下情况使用 `/go-build`：
+
+* `go build ./...` 因错误而失败
+* `go vet ./...` 报告问题
+* `golangci-lint run` 显示警告
+* 模块依赖关系损坏
+* 拉取更改后导致构建失败
+
+## 运行的诊断命令
+
+```bash
+# Primary build check
+go build ./...
+
+# Static analysis
+go vet ./...
+
+# Extended linting (if available)
+staticcheck ./...
+golangci-lint run
+
+# Module issues
+go mod verify
+go mod tidy -v
+```
+
+## 示例会话
+
+````text
+User: /go-build
+
+Agent:
+# Go Build Resolution
+
+## Initial Diagnostics
+
+```bash
+$ go build ./...
+internal/service/user.go:25:15: undefined: UserRepository
+internal/handler/api.go:42:9: cannot use x (type string) as type int
+internal/handler/api.go:58:2: missing return at end of function
+````
+
+发现错误：3
+
+## 修复 1：未定义的标识符
+
+文件：internal/service/user.go:25
+错误：undefined: UserRepository
+原因：缺少导入
+
+```go
+// Added import
+import "project/internal/repository"
+
+// Changed
+var repo UserRepository
+// To
+var repo repository.UserRepository
+```
+
+```bash
+$ go build ./...
+# 2 errors remaining
+```
+
+## 修复 2：类型不匹配
+
+文件：internal/handler/api.go:42
+错误：cannot use x (type string) as type int
+
+```go
+// Changed
+count := params.Get("count")
+// To
+countStr := params.Get("count")
+count, _ := strconv.Atoi(countStr)
+```
+
+```bash
+$ go build ./...
+# 1 error remaining
+```
+
+## 修复 3：缺少返回
+
+文件：internal/handler/api.go:58
+错误：missing return at end of function
+
+```go
+func GetUser(id string) (*User, error) {
+    if id == "" {
+        return nil, ErrInvalidID
+    }
+    user := findUser(id)
+    // Added missing return
+    return user, nil
+}
+```
+
+```bash
+$ go build ./...
+# Build successful!
+```
+
+## 最终验证
+
+```bash
+$ go vet ./...
+# No issues
+
+$ go test ./...
+ok      project/internal/service   0.015s
+ok      project/internal/handler   0.023s
+```
+
+## 摘要
+
+| 指标 | 数量 |
+|--------|-------|
+| 已修复的构建错误 | 3 |
+| 已修复的 Vet 警告 | 0 |
+| 已修改的文件 | 2 |
+| 剩余问题 | 0 |
+
+构建状态：✅ 成功
+
+```
+
+## Common Errors Fixed
+
+| Error | Typical Fix |
+|-------|-------------|
+| `undefined: X` | Add import or fix typo |
+| `cannot use X as Y` | Type conversion or fix assignment |
+| `missing return` | Add return statement |
+| `X does not implement Y` | Add missing method |
+| `import cycle` | Restructure packages |
+| `declared but not used` | Remove or use variable |
+| `cannot find package` | `go get` or `go mod tidy` |
+
+## Fix Strategy
+
+1. **Build errors first** - Code must compile
+2. **Vet warnings second** - Fix suspicious constructs
+3. **Lint warnings third** - Style and best practices
+4. **One fix at a time** - Verify each change
+5. **Minimal changes** - Don't refactor, just fix
+
+## Stop Conditions
+
+The agent will stop and report if:
+- Same error persists after 3 attempts
+- Fix introduces more errors
+- Requires architectural changes
+- Missing external dependencies
+
+## Related Commands
+
+- `/go-test` - Run tests after build succeeds
+- `/go-review` - Review code quality
+- `/verify` - Full verification loop
