Writing (in-ns \'dbx) to a file and loading it isn\'t changing the default namespace of the repl (using cygwin/console). The namespace is still user=><
Using tools.deps one way would be to define an alias and execute some forms in it:
:aliases
{:cursive {:main-opts ["-e" "(load \"de/sveri/getless/user\")"
"-e" "(de.sveri.getless.user/reset)"]}
This will load the de.sveri.getless.user namespace and execute the de.sveri.getless.user.reset function afterwards.
