Before your AI agent pays for you: four questions about authorization and billing

Context: Amazon cut off the MUSE agent from using the Amazon app, sparking debate over whether tools will charge agents to recoup lost ad revenue. The author argues personal agents are unstoppable, but "being able to buy" doesn't mean "the ledger is yours."
The real risks are billing and authorization ambiguity: whether a call is bound to "read" or "pay" permissions; whether the agent explicitly opts out when a tool raises prices or silently switches vendors; and whether payment paths you've vetoed resurface in later sessions.
Four tests for a real Personal AI:
- Charges can be traced back to a specific authorization
- Permissions are layered (read / order / pay), not all-or-nothing
- Explicit opt-out when tools refuse or raise prices
- Vetoed payment paths persist across sessions
Bottom line: agents completing orders isn't enough — every charge must trace to your explicit nod.
