Hello @nicholasoxford,
thank you very much for creating a Pull Request!
Here is a small checklist to get this PR merged as quickly as possible:

• Do all subcommands / options which take arguments have the arg property (arg: {})?
• Are all options modular? E.g. a -u -x instead of -aux
• Have all other checks passed?

Please add a 👍 as a reaction to this comment to show that you read this.

you should be able to get this same information faster & more accurately via bun getcompletes s. I need to add support for returning the contents of the script rather than just the script name, but I'm happy to do that.

bun c shorthand exists for bun create - should be ["c", "create"]
