I recently started exploring Agent Skills. While I find the concept genuinely useful, there are three questions immideately coming up my mind:

1) How to avoid bloating of .agents/skills with "may be useful one day" files?

The nature of skills would tempt me to make a large collection relevant to project tech stack. But each skill can be accompanied by tens if not hundreds of associated resources and additional files.

How to decide what can be really useful and what is not?

2) How to keep downloaded skill files up-to-date?
