In general, we'll take all well-written completion scripts for a command that is publically available.
This means no private tools or personal scripts, and we do reserve the right to reject for other reasons.
Before you try to contribute them to fish, consider if the authors of the tool you are completing want to maintain the script instead.
Often that makes more sense, specifically because they can add new options to the script immediately once they add them,
and don't have to maintain one completion script for multiple versions. If the authors no longer wish to maintain the script,
they can of course always contact the fish maintainers to hand it over, preferably by opening a PR.
This isn't a requirement - if the authors don't want to maintain it, or you simply don't want to contact them,

6. Try not to use minor convenience features right after they are available in fish - we do try to keep completion scripts backportable.
If something has a real impact on the correctness or performance, feel free to use it,
but if it is just a shortcut, please leave it.

Put your completion script into share/completions/name-of-command.fish. If you have multiple commands, you need multiple files.
If you want to add tests, you probably want to add a littlecheck test. See below for details.
