Skill library

The skills a user has added to their assistant, grouped by who made them: their own, their team's, and the ones that ship with the product. Every row has a switch, and says whether the assistant reaches for the skill on its own or only on request. A row opens in place to its full description, that choice, and update and remove. A second side holds Discover, and a first-run banner points there. Lists automatic skills for AI SDK instructions.
