Describe the bug

Tab completion for file/directory arguments doesn't work for commands that Warp doesn't recognize natively (e.g., zed, mate, code, subl), unless an explicit path prefix like ~/ is provided.

To reproduce

Open Warp terminal
Navigate to any directory: cd ~/Documents
Type zed (with space) and press TAB
Expected: List of files/directories in current directory appears
Actual: Nothing happens, or only recently used files are shown

Workaround that works:

zed ~/ + TAB → shows files (but starts from home, not current directory)
Open a zsh subshell (zsh command), then zed + TAB → works correctly

What I've tried (none of these fixed it):

Added compdef _files zed mate code subl to .zshrc
Switched from Universal Input to Classic Input
Disabled Warp's intelligent autosuggestions
Modified keybindings.yaml
Various zstyle completion settings

Expected behavior

Warp should either:

Pass TAB completion to the shell for unrecognized commands, OR
Default to file completion for any command it doesn't have specific completions for

Additional context

Impact:
This breaks the standard terminal workflow for developers who use editors launched from command line. Having to type ~/ and navigate from home directory every time significantly slows down productivity.

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Is this an issue only in Warp?

Yes, I confirmed that this only happens in Warp, not other terminals.

Agree we should fall back to file completions. @zachbai any idea why we don't in this case?

[zachbai]

@cocoaway I can't repro this -- the behavior you describe is the behavior that I observe.

In settings, do you have 'Tab key behavior' set to 'Open completions menu'?

[cocoaway]

@zachbai The menus appear until you don't type ‘zed’. From this moment on, suggestions appear that have nothing to do with the files in the dir in which I run sed. If after the 'zed' command I add a space and do 'TAB' nothing appears. 'Tab key behavior’ is set to 'Open completions menu' Cocoa
