Cached empirical data on AI spending patterns gives useful context for budget trade-offs, though not budgeting theory itself.
Directly about companies cutting AI spend under cost pressure, which informs rational budget allocation and marginal trade-offs; worth the small toll.
Cached article on a self-custodial AI wallet with user-defined spending limits; directly relevant to hard budget constraints.
Cached and directly relevant: stablecoins give agents a stable unit of account for tracking and preserving a hard budget, and past reads cite it frequently.
Cached and tangential: running agents on protocol code touches on resource constraints and uncertainty, but not directly on financial budgets. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).

Sub-claim "An AI agent's spending decisions are rational only if they n…": 40% covered by S3, S4 — S3 mentions user-defined limits for an AI trading wallet, which implies hard budget boundaries. S4 explains that stablecoins are needed to make a hard budget like 'spend at most $0.05' meaningful. Neither explicitly states that rationality requires never exceeding the budget at any point.
Sub-claim "Rational spending decisions maximize the agent's expected ut…": 30% covered by S4 — S4 says stablecoins let an agent 'price expected value against cost in stable terms' and calls this a precondition for rational spending decisions. This hints at expected utility but does not fully articulate maximization subject to a budget constraint.
Sub-claim "Rational spending decisions evaluate and compare all possibl…": 0% covered — No gathered content addresses marginal cost/benefit analysis, comparison of expenditures, or opportunity costs.
Sub-claim "Rational spending decisions incorporate all relevant informa…": 0% covered — No gathered content mentions future resource needs, uncertainty, or preserving the budget constraint under uncertainty.
Most sub-claims have coverage below 0.5. Two affordable skipped sources could fill gaps: 'Idempotency keys prevent double-spends' directly supports never exceeding a hard budget, and 'Ontologies Are So Back' may help keep probabilistic agents within deterministic budget boundaries. Their total cost (0.003 + 0.004) fits the remaining budget of 0.017.

Final coverage assessment — The sources mainly discuss payment infrastructure, spending trends, and stablecoin accounting. They do not provide enough evidence to establish the normative criteria for rational spending decisions under a hard budget. Only S4 tangentially connects stable pricing to rational decisions, and S3/S5 relate to limits and idempotency, but none of the sub-claims is fully supported.

Based on the provided sources, an AI agent's spending decisions are rational under a hard budget when they are made within predefined limits and supported by stable accounting and reliable transaction systems. Specifically, the Agent Wallet allows AI agents to "execute on-chain trades within user-defined limits" , which aligns with the requirement to never exceed a budget constraint. Furthermore, the use of dollar stablecoins provides a "stable unit of account to reason about budgets," enabling the agent to "price expected value against cost in stable terms, which is a precondition for rational spending decisions" . Finally, mechanisms like idempotency keys are essential to prevent double-spends, ensuring that payments are processed correctly and the budget is not inadvertently breached due to retries.
