Solutions

Pass the file to edit: `wsh editor <file-or-url>`
Check that your script's file path variable is not empty
Run `wsh editor --help` for usage

Example fix

// before
wsh editor
// after
wsh editor ~/config/settings.json

Defensive patterns

Strategy: validation

Validate before calling

args := os.Args[2:] // after subcommand parsing
if len(args) == 0 {
    return errors.New("wsh editor needs one file or URL argument")
}

Prevention

Always pass a file/URL to `wsh editor`
Guard scripts: `[ -n "$file" ] || exit 1` before invoking
Read `wsh editor --help` for accepted arguments

When it happens

Trigger: Running bare `wsh editor` with no file or URL argument.

Common situations: Typing `wsh editor` expecting it to open a picker; a script variable holding the filename was empty.
