Taskfile.yml:

---
version: "3"

vars:
  PATH: /tmp/{{ .NAME }}/.tmp

tasks:
  print:
    cmds:
      - echo {{ .NAME }}
      - echo {{ .PATH }}

the result of the task:

[]$ task print NAME="test"
task: [print] echo test
test
task: [print] echo /tmp//.tmp
/tmp//.tmp

I didn't find any reference to it in the documentation, but it looks like Taskfile does not expand the environmental variable properly, variable NAME is expanded in the task section, but when it's assigned to another var in global section (PATH: /tmp/{{ .NAME }}/.tmp it's just empty string instead
