# Go Linting
## Core Principle
More important than any "blessed" set of linters: **lint consistently across a codebase**.
Consistent linting helps catch common issues and establishes a high bar for code quality without being unnecessarily prescriptive.
## Resource Routing
- `scripts/setup-lint.sh` - Run when generating a `.golangci.yml`, validating the first lint pass, or producing JSON metadata. - `assets/golangci.yml` - Use as the v2 golangci-lint baseline for established projects.
## Setup Procedure
1. Create `.golangci.yml` with `scripts/setup-lint.sh` or copy `assets/golangci.yml` 2. Run `golangci-lint run ./...` 3. If errors appear, fix them category by category (formatting first, then vet, then style) 4. Re-run until clean
After generating `.golangci.yml`, run `golangci-lint config verify --config .golangci.yml` to verify the configuration schema before relying on lint results.
---
## Minimum Recommended Linters
These linters catch the most common issues while maintaining a high quality bar:
| Linter | Purpose | |--------|---------| | [errcheck](https://github.com/kisielk/errcheck) | Ensure errors are handled | | [goimports](https://pkg.go.dev/golang.org/x/tools/cmd/goimports) | Format code and manage imports | | [revive](https://github.com/mgechev/revive) | Common style mistakes (modern replacement for golint) | | [govet](https://pkg.go.dev/cmd/vet) | Analyze code for common mistakes | | [staticcheck](https://staticcheck.dev) | Various static analysis checks |
> **Note**: `revive` is the modern, faster successor to the now-deprecated `golint`.
---
## Lint Runner: golangci-lint
Use [golangci-lint](https://github.com/golangci/golangci-lint) as your lint runner. See the [example .golangci.yml](https://github.com/uber-go/guide/blob/master/.golangci.yml) from uber-go/guide.
---
## Example Configuration
Use `assets/golangci.yml` as the maintained example. It targets golangci-lint v2 (verified with 2.10.1 on 2026-06-19), keeps `goimports` under `formatters`, and enables the core linters plus common production additions.
### Running
```bash # Install the version this skill's config is verified against go install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.10.1
# Run all linters golangci-lint run
# Run on specific paths golangci-lint run ./pkg/... ```
---
## Additional Recommended Linters
Beyond the minimum set, consider these for production projects:
| Linter | Purpose | When to enable | |--------|---------|----------------| | [gosec](https://github.com/securego/gosec) | Security vulnerability detection | Always for services handling user input | | [ineffassign](https://github.com/gordonklaus/ineffassign) | Detect ineffectual assignments | Always — catches dead code | | [misspell](https://github.com/client9/misspell) | Correct common misspellings in comments/strings | Always | | [gocyclo](https://github.com/fzipp/gocyclo) | Cyclomatic complexity threshold | When functions exceed ~15 complexity | | [exhaustive](https://github.com/nishanths/exhaustive) | Ensure switch covers all enum values | When using iota enums | | [bodyclose](https://github.com/timakin/bodyclose) | Detect unclosed HTTP response bodies | Always for HTTP client code |
---
## Nolint Directives
When suppressing a lint finding, always explain why:
```go //nolint:errcheck // fire-and-forget logging; error is not actionable _ = logger.Sync() ```
Rules: - Use `//nolint:lintername` — never bare `//nolint` - Place the comment on the same line as the finding - Include a justification after `//`
---
## CI/CD Integration
Run `golangci-lint run ./...` in CI after tests. Pin the golangci-lint version used by CI so local and release behavior do not drift.
### Pre-commit Hook
```bash #!/bin/sh # .git/hooks/pre-commit golangci-lint run --new-from-rev=HEAD~1 ```
Use `--new-from-rev` to lint only changed code, keeping the feedback loop fast.
---
## Quick Reference
| Task | Command/Action | |------|----------------| | Install golangci-lint | `go install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.10.1` | | Run linters | `golangci-lint run` | | Run on path | `golangci-lint run ./pkg/...` | | Config file | `.golangci.yml` in project root | | CI integration | Run `golangci-lint run` in pipeline | | Nolint directives | `//nolint:name // reason` — never bare `//nolint` | | CI integration | Use `golangci/golangci-lint-action` for GitHub Actions | | Pre-commit | `golangci-lint run --new-from-rev=HEAD~1` |
### Linter Selection Guidelines
| When you need... | Use | |------------------|-----| | Error handling coverage | errcheck | | Import formatting | goimports | | Style consistency | revive | | Bug detection | govet, staticcheck | | All of the above | golangci-lint with config |
