 ## Command executions
 
 Your command will get a JSON object passed through `stdin` you can parse to gain details about the message. It is expected to yield an array of actions on `stdout` and exit with status `0`. If it does not the action will be marked failed. In case you need to output debug output you can use `stderr` which is directly piped to the bots `stderr`.
