What version of Codex is running?

0.1.2504172351

Which model were you using?

not applicable

What platform is your computer?

What steps can reproduce the bug?

in fish shell:

codex completion fish

produces:

# fish completion for codex
complete -c codex -a '(_fish_complete_path)' -d 'file path'

Activate completion via:

codex completion fish > ~/.config/fish/completions/codex.fish && exec fish
# (the only ways I know how to install/activate completions in fish)

What is the expected behavior?

press tab after typing "codex " in prompt --> completions of the codex command

What do you see instead?

codex fish: Unknown command: _fish_complete_path                                                                                       home 04:17
