Hi! I'm trying to add commands to devShell, like this:

          commands = [
            {
              name = "run-client";
              command = "nixGLIntel client -v --host c71ee55ef19fb0c4b934610d-1024-game-server.challenge.master.camp.allesctf.net -p 31337 --ssl --username 'justCatTheFish!1' --password password123";
            }
          ];

But I get this error:

[...]
          162|
          163|                  commands = [
             |      ^
          164|                      {

       error: cannot coerce a set to a string

What's the correct syntax?

So, I have my main flake that I use for all my configs, and then I can add inputs at the top level, and import module configurations for all of my setup. Is there and idiomatic way for one of those modules included by modules to also be able to add their own flakes, or do you need to bring them in at the top level input and pass them down to the module using the various ways?
