Is your feature request related to a problem? Please describe.
need to make skills marketable, rentable, usable by users other than the skill creator.

Describe the solution you'd like

1. a set of "public" skills, free of charge, any one can view it, download it, modify it.
2. an skill creator can "publish"/"unpublish" skill he/she creates, once published, the skill be searched and viewed by others.
3. an skill creator can make a published skill free or non-free, if for free, others can view/download the skill source. if not for free, others can pay for the use (in such a case, it's source code is no longer viewable), and the skill can only be a cloud skill or hybrid cloud skill.

Describe alternatives you've considered
None

Additional context

1. the code is already here, just need to be verified (or modified).
2. what is a skill: 1 zipped set of text files (the core is a flowgram json describing a workflow, along with its associated data mapping file, prompt files (or pointer to prompt files), tools, hot-path code etc.)
