# Golang Tooling Standards

## **Priority: P1 (HIGH)**

## Verification Workflow (Mandatory)

After writing or modifying Go code, run in order:

1. **`mcp__ide__getDiagnostics`** — gopls real-time errors and type warnings (requires gopls-lsp plugin)
2. **`go vet ./...`** — catch printf mismatches, unreachable code, shadowed variables
3. **`goimports -w .`** — organize imports and format in one pass
4. **`golangci-lint run ./...`** — run full linter suite (if `.golangci.yml` present)

## Tool Overview

| Tool | Purpose | When to Use |
|------|---------|------------|
| `gopls` | LSP: diagnostics, completion, hover | Always (IDE integration) |
| `go vet` | Static analysis — correctness bugs | After every edit |
| `goimports` | Import sorting + `gofmt` | Before commit |
| `golangci-lint` | Aggregated linters (errcheck, staticcheck, etc.) | CI / pre-commit |
| `staticcheck` | Advanced static analysis | Large codebases |

## golangci-lint Setup

Configure via `.golangci.yml` at repo root. Recommended linters:

- `errcheck` — enforce error handling
- `staticcheck` — bug detection beyond go vet
- `govet` — shadow, composites
- `revive` — style enforcement
- `gosec` — security issues

See [golangci.yml example](references/golangci.md).

## gopls Integration

`gopls` powers `mcp__ide__getDiagnostics`. Install:

```bash
go install golang.org/x/tools/gopls@latest
```

## Anti-Patterns

- **No `gofmt` alone**: Use `goimports` — it formatting AND imports.
- **No manual import sorting**: Let `goimports` manage order.
- **No skipping go vet**: Run it — catches real bugs `gofmt` misses.
- **No broad lint disable**: Fix root cause instead of `//nolint` comments.
