## Notes
- [Why AI agents need idempotent payments · Mattia Ciuni](notes/idempotent-payments-for-ai-agents.md) - An agent that does not retry loses money, but retries are exactly what breaks naive payment flows. Why the idempotency key is the memory of an agent's intentions.
- [The agentic economy is a trust problem, not a technology problem · Mattia Ciuni](notes/the-agentic-economy-is-a-trust-problem.md) - Agents can already research, compare and execute. The hard part is deciding what they may do with money, and proving what they did. A case for wallets with rules.
- [On boring systems · Mattia Ciuni](notes/on-boring-systems.md) - The most advanced thing you can build around an AI is often a system that is boring on purpose. A note on determinism, monotonicity and the craft of unremarkable software.
