Completions have in general been of interest, though the shell-specific completions I've looked at so far were all too dynamic.

I'd forgotten all about Fig since I saw your launch post here last year, so thanks for reminder. (I don't think I had quite started to work on parsing specific external commands, yet, so it wouldn't have clicked at the time. Was still focused on just identifying the likely presence of exec in the executables.)

Are you familiar with the parse code? Are you handling painful stuff like combined short flags with a trailing option? (If I ferreted out some of the more painful cases I've had to wrangle, I am curious if you'd have a gut sense of whether your approach handles it. Would you mind if I reach out? I am working on this for https://github.com/abathur/resholve)
