The 2026 development
Anthropic's Project Deal assigned agents to buy, sell and negotiate in an internal marketplace.
The governance gap
Two agents negotiating can collude, misrepresent or converge on a price that neither principal authorised. The principals' mandates, not the agents' preferences, have to bound the deal.
Where CAIN-42 fits: Moat 2 — Security-Context Continuity
Core question: Does authority survive every boundary? Identity, scope and delegation are carried across tools, agents, memories and systems.
Put both sides' mandates into the settlement check: price ceiling, quantity, counterparty and expiry. A deal that exceeds either mandate is refused even if both agents agree.
How the wiring works
- Record each principal's mandate before negotiation.
- Evaluate the proposed deal against both mandates.
- Detect collusion and self-dealing across the agent graph.
- Settle only when both sides are within authority.
