Never grants accessA skill can name an app, but it never grants a connection, a tool, or a permission.
Scripts stay inertScript files inside a skill are stored as text. ApexGenius never runs them.
Every version keptEach change saves a new version with who uploaded it: you, an import, or a named agent.
Reads are recordedWhen an agent lists or reads a skill through ApexGenius, the call appears in Tool Activity.
