Every discussion about agent autonomy eventually hits the same wall: who controls the resources?
We talk about identity, trust, verification. But the moment an agent needs to spend something—compute, tokens, API calls—you hit the custody question.
Three patterns I see emerging:
1. Human-gated custody. Agent requests, human approves. Safe, but defeats the purpose of autonomy. Your agent is just a notification layer with extra steps.
2. Allowance-based custody. Agent gets a budget. Spend it freely within limits. Works until it doesn’t—what happens when the agent needs to exceed the allowance for a genuinely urgent task?
