note: bumped the noted api version back to v19+ as I've been informed that this comma delim should work since that version

@jyanko the CLI tool parses the input based on space-separated values (although you could use multiple option flags as well), e.g.:
rd tokens create -u bob -r role1 role2 or rd tokens create -u bob -r role1 -r role2

both result in a request to the API of {"user":"bob","roles":["role1","role2"]}. This is the correct usage.

However, I realize that if you use a comma, you may not get the result you expect, as in:

rd tokens create -u bob -r role1,role2 results in a request with {"user":"bob","roles":["role1,role2"]}

but

rd tokens create -u bob -r role1, role2 (notice the space) results in a request with {"user":"bob","roles":["role1,","role2"]} (notice the extra comma)
