Ive tried to add it like this and just get a whole page of errors.

"Parameters": [""],
"Command": "inventory.giveto {username} Supply Signal 1"
}​

your missing the Parameters is why
It should look like this

{
  "Parameters": [
  "{username}",
  "supply.signal",
  "1"
],
"Command": "inventory.giveto"
}​​
