Summary

One way to express dependencies and guards: the Condition field on Meta.

condition.Shell("pgrep nginx")                                    // exit 0 = met
condition.Shell("cat /etc/hostname").Match("web01")               // output match
condition.Shell("Get-Feature ...").In("pwsh").Match("Enabled")    // explicit shell
condition.Resource("package:nginx")                               // DAG dependency
condition.All(condition.Resource("pkg:nginx"), condition.FileExists("/etc/nginx"))
condition.Not(condition.Shell("pgrep legacy"))

Test plan

• go build ./... passes (Linux, macOS, Windows)
• go test -race ./... passes
• go vet ./... clean
