take a example if i wanna learning a topic related medical，so i have to setup own references and resources in order to teach me right?

Yes, I would give it some curated references rather than leaving it to general memory alone.

For a focused topic like medical, the skill becomes much more useful when you provide a small set of trusted sources, examples, and terms it should stay grounded in.

So the answer is basically: yes, you want to set up references, but it does not need to be huge. A narrow, well-chosen source set is usually enough.

To add to what starkmarkus said — the /teach skill has a specific structure worth knowing here.
It maintains a RESOURCES.md file in your workspace to track trusted sources, and a ./reference/ folder for compressed learnings like glossaries and cheat sheets. For a domain like medicine, you'd want to populate RESOURCES.md with your trusted links (e.g. PubMed, specific textbooks, official clinical guidelines) before starting lessons.
The good news: it doesn't have to be a big list. Even 2–3 high-quality, authoritative sources are enough — the skill is designed to stay grounded in them and cite them in lessons rather than drift into general memory. The narrower and more trusted the source set, the more reliable the teaching will be.
So yes — set up your references first, then run /teach. That's the intended workflow.
