The fundle completions rely on your fish-completion-helpers (https://github.com/tuvistavie/fish-completion-helpers) for both __fish_prog_needs_command and __fish_prog_using_command however they're not mentioned in the readme. Perhaps there should be a section in the readme for the completions mentioning the requirement on fish-completion-helpers?
I personally solved this by just installing fish-completion-helpers with fundle.
