Since I try to stick to Apple solutions and free software* I prefer using Spotlight instead of all the smart launchers that we have for macOS.
What I do is that I call my script names that are easy to call first in Spotlight. A few screenshots speak louder than words so here we are:
The series that start with ">" usually is scripts that I use to open something.
See how just typing ">" suggests ">BB". That ">BB" is what I use to open the files selected in Finder with BBEdit.
The one below is ">Tedit", short for "TextEdit" and opens selected files in TextEdit, etc.
If I type "c" after ">", I get the following list of choices. ">command" is to launch an arbitrary command in Terminal, ">Capture" is to use org capture in Emacs (see here and here for more information) and ">cd" just opens a Terminal tab on the front Finder window, or selected Finder folder.
When I use "<" to initiate the search, I get a different list. That series is for scripts that usually act by themselves. "<text file" creates a text file in the front Finder window and proposes to open it in BBEdit for editing, "<facturation" is an invoicing script for the job selected in Finder, "<job" is a job managing script that creates a job hierarchy in Finder based on a mail, along with an event in calendar, and then "<xls2tmx" is a TMX converter for multicolumn Excel reference data (I'll publish it when it's more polished, but creating XML data with AppleScript is documented here).
I have a few more scripts (a dozen) that I routinely call with Spotlight, which I find totally sufficient for my needs.
As you know, hitting Command+Enter when you have a selection in Spotlight is a way to reveal that selection in the Finder if it is available. So when I want to edit a script, I start by calling it in Spotlight, I hit Command+Enter when it is selected and then I call ">SEditor" (Script Editor) or ">debugger" (Script Debugger) on the selection, to open it with the appropriate application...
* Ok, I do have BBEdit, Microsoft Office and Illustrator... And maybe a few others...
