AI agents risk duplicate actions due to stateful failures, author proposes external gate

A common failure mode in AI agents involves duplicate execution of tools with significant side effects, such as issuing refunds or sending emails. Existing safety measures like OAuth, RBAC, and prompt instructions often fail to prevent these stateful errors because they are either static or advisory, and do not account for the agent's execution history. The author proposes a solution: an external gate that wraps tool calls, maintaining state outside the agent's context to enforce idempotency and prevent duplicate actions, circuit breakers for runaway loops, and scoped approvals.

    Prompts and RBAC won't stop your agent from refunding someone twice

    <p>If you let an agent call tools that have real side effects — refunds, emails, exports, writes to prod — there's a class of failure that none of the usual safety layers actually catch. I keep running into it while building in this space, so I want to lay out the problem clearly…
