# Go Modern Version Modern Go is a **version surface**: the module's Go version determines which language and standard-library forms are available. Read the affected module's `go.mod`. When version availability affects the planned choice or modernization is requested, query the pinned JetBrains inventory from the repository root against that module's Go file or `go.mod`: ```bash go tool -modfile=tools/go.mod go-modern-guidelines list --file-path <path> ``` Reuse the inventory for the same resolved version. Read and explain only guidelines that may affect the diff. Text-only edits or edits with no version-dependent choice need no inventory. For a modernization spanning multiple files, record applicable guideline IDs and a disposition per affected file; a single local choice needs only its rationale and focused proof. The wrong default is copying nearby legacy syntax after the target version supports a clearer form. Apply the modern form unless it changes behavior, error identity, nil or empty meaning, aliasing, ordering, performance contracts, or source ownership; those semantic owners take precedence. Complete when the chosen forms are available at the module's version and the affected behavior is preserved with focused proof. A modernization sweep also accounts for each affected file as applied, not applicable, or blocked with an exact reason. Use the active workflow's validation plan.
