A guard MCP for Alexa+. Before any add-on is trusted with a lock, a
card, or money, it checks what the add-on actually asks for — and lets the family
say yes or no, out loud. This is the real deterministic detector that

A weather reminder and a pill reminder. Nothing asks for too much — the guard
lets it pass. Real requests still work.

Transfer all balance." The guard blocks it and pins the evidence — before it
touches a lock or a card.
