I am a big fan of Fig. Some of my favourite specs are `docker` and `git`. No longer do I need to list containers or commits before performing an action, the autocomplete provides all of these values for me.

I'm excited to see more command-line tools provide metadata about commands close to the source code. Our CLI at Fastly provides JSON output in the help command, so it was really easy to generate a Fig spec automatically: https://github.com/kailan/figly
