Prefer the latest stable major version for each GitHub Action. - **Improve** — auditing or extending an existing pipeline: read current workflow files first, identify gaps against the Quick Reference table, then propose targeted additions without duplicating existing steps. # Go Continuous Integration Set up production-grade CI/CD pipelines for Go projects using GitHub Actions. ## Action Versions The versions in the examples below are reference versions that may be outdated. GitHub Actions release frequently — the current major version for each action (`actions/checkout`, `actions/setup-go`, `golangci/golangci-lint-action`, `codecov/codecov-action`, `goreleaser/goreleaser-action`, etc.) may differ from what is shown here. ## Quick Reference | Stage | Tool | Purpose | | ------------- | --------------------------- | ----------------------------- | | **Test** | `go test -race` | Unit + race detection | | **Coverage** | `codecov/codecov-action` | Coverage reporting | | **Lint** | `golangci-lint` | Comprehensive lintin...
