SkillEntry

type SkillEntry =
  | SkillLike
  | SkillStoreLike
  | string
  | readonly PackagedSkill[]
  | SkillResolver;

One way to supply skills. A string is a filesystem root scanned for <dir>/SKILL.md, resolved against the agent’s workspace filesystem. A SkillResolver function resolves per-session/per-tenant skills; it is the only callable member of this union (see isSkillResolver).
