+### Go environment outputs
+
+Once Go is on the `PATH`, the action exposes the most commonly needed `go env` variables as outputs, so workflows don't have to query them in duplicated `bash`/`pwsh` steps — one expression works on Linux, macOS, and Windows. The values are a snapshot from setup time: anything a later step changes, such as setting `GOOS`/`GOARCH` to cross-compile, is not reflected.
+
+| Output | `go env` variable | Notes |
+| --- | --- | --- |
+| `go-path` | `GOPATH` | Go workspace root; `bin` and `pkg/mod` live under it |
+| `go-bin` | `GOBIN` | Go 1.27+ reports an implicit `$GOPATH/bin` default; earlier releases are empty unless `GOBIN` is set |
+| `go-bin-path` | `GOBIN` or `$GOPATH/bin` | The base Go binary directory, using the first `GOPATH` entry. Cross-compiled binaries go one level deeper, in `$GOPATH/bin/$GOOS_$GOARCH` |
+| `go-root` | `GOROOT` | Installation directory of the Go toolchain in use |
+| `go-cache` | `GOCACHE` | Build cache directory |
+| `go-mod-cache` | `GOMODCACHE` | Module cache directory |
+| `go-os` | `GOOS` | Go notation (`linux`, `darwin`, `windows`), unlike `runner.os` |
+| `go-arch` | `GOARCH` | Go notation (`amd64`, `arm64`), unlike `runner.arch` or the `x64` in the action's cache key |
+| `go-tool-dir` | `GOTOOLDIR` | Holds `compile`, `link`, `vet` and the other toolchain binaries |

+
+Quote `go-bin-path` in shell commands, since it may contain spaces. Variables without a dedicated output are not exposed; run `go env <NAME>` in a step when you need one.
+
+> [!NOTE]
+> These outputs need Go 1.9 or newer (`go env -json`); on older releases the action logs a message, leaves them unset and does not fail. `go-cache` needs Go 1.10 and `go-mod-cache` needs Go 1.15.
