Spending controls for AI agents
Spending controls define the conditions under which an agent may propose or initiate a financial action. A limit is meaningful only when its scope, enforcement point, data source and failure behaviour are clear.
Choose limits that match the risk
A single maximum amount rarely captures every risk. Depending on the use case, a policy may need a per-action ceiling, a period budget, an allowed category or counterparty, and an approval threshold. Define what resets each limit and which clock or currency is used.
- State whether values are requested, authorized, reserved or settled.
- Specify how pending actions count against a budget.
- Define treatment of fees, currency conversion and partial completion.
- Make a denied or ambiguous request visible rather than silently retrying.
Do not confuse a displayed balance with enforcement
A user interface can show a budget without preventing an external system from exceeding it. Verify which component checks the rule, whether it does so atomically and how concurrent requests are handled.
Budget calculations also need a trusted source of transaction status. A proposal, an authorization and a completed movement must not be counted as if they were the same event.
