Before you install any skill

Who publishes it? Prefer the AI vendor or the company that owns the app being connected.
Has it been reviewed? Look for a verified badge, or the security ratings on its skills.sh page.
What accounts does it connect to, and what can it do there? Prefer read-only; check anything that can send, pay or delete.
Does it run commands on your computer? A “Warn” rating often means it does, even for official skills.
Has your IT team approved it? Use the admin-managed catalogue where there is one.
Do you know how to disconnect it and revoke its access?
Finance, legal and HR output still needs review by a qualified person.

This map is a by-product of the work. Keeping track of what each of these actually does, and which ones are worth your time, is part of how I advise founder-led companies on AI. If you want that applied to your business, the first conversation is free.
