The error handling for the Go command execution is inadequate. If the Go script fails, the justfile will continue execution without indication of failure. Consider adding error handling or using a shell operator to propagate failures.

Suggested change

	@go run ${FABRICATOR_PATH:-../../fabricator}/hack/generate_viewer.go --dirs "env-ci-1.l/diagrams" --output-dir . --output-file diagram-viewer.html
	@go run ${FABRICATOR_PATH:-../../fabricator}/hack/generate_viewer.go --dirs "env-ci-1.l/diagrams" --output-dir . --output-file diagram-viewer.html || exit 1

The error message provides a generic installation URL but doesn't specify the minimum Go version required. This could lead to compatibility issues if an older Go version is installed.

Suggested change

	@command -v go >/dev/null 2>&1 || (echo "Go not installed. Install from https://golang.org" && exit 1)
	@command -v go >/dev/null 2>&1 || (echo "Go not installed or version too old. Please install Go >= 1.18 from https://golang.org/dl/" && exit 1)
