Looks interesting, how would you use skills with that? Would I need to migrate them into prompts? Which I think is not the same.

E.g. how to use official, vendor provided skills with zerostack? https://github.com/elestio/elestio-skill

Technically, a skill is equivalent to adding

'"The skill description": if this applies, read /path/to/skill/definition.md'

To your agents.md

At least currently skills don't let you set the model (to my knowledge), so that's not a distinction either here (it would be with agent definitions)
