Sub-claim "Rational spending decisions under a hard budget involve maxi…": 40% covered by S5 — S5 mentions that an agent under a hard budget must choose which sources are worth paying for and that every purchase is a reasoned trade-off, but it does not explicitly discuss utility maximization or the formal budget constraint. Coverage is partial.
Sub-claim "Rationality requires evaluating each potential expenditure b…": 30% covered by S5, S10 — S5 notes trade-offs in purchasing decisions and that the budget produces emergent frugality. S10 discusses paying sources in proportion to contribution, which hints at benefit-cost evaluation. However, neither source explicitly mentions marginal benefit or prioritization based on benefit per cost. Coverage is limited.
Sub-claim "Rational decisions account for opportunity costs, meaning sp…": 20% covered by S5 — S5 mentions choosing which sources to pay for, implying some trade-offs, but it does not explicitly discuss opportunity costs or the foregone benefits of alternative spending. Coverage is minimal.
Sub-claim "Under a hard budget, rational agents must adjust their spend…": 10% covered — No gathered source directly addresses dynamic reallocation of resources in response to changing costs or benefits under a budget constraint. Coverage is negligible.
All sub-claims have coverage below 0.5, indicating significant gaps. The skipped sources are inexpensive (prices from 0.002 to 0.004) and fit within the remaining budget of 0.02. However, none of the skipped sources appear to directly address the theoretical aspects of rational spending under a hard budget (e.g., utility maximization, marginal benefit, opportunity cost, dynamic reallocation). They focus on unrelated topics like Bitcoin price movements, AI marketing agents, AI tutor behavior, sanctions, DeFi, gardening, retro gaming, and spiritual journeys. Therefore, purchasing any of them would not improve coverage for these claims. No recommended purchases.

Final coverage assessment — The sources provide only partial, indirect support for the subclaims. S5 discusses reasoned trade-offs under a hard budget and S1 mentions the precondition of a stable unit of account, but no source explicitly covers utility maximization, marginal benefit/cost prioritization, opportunity costs, or dynamic reallocation under changing costs/benefits. Most gathered articles are unrelated to AI agent budget rationality.

Under a hard budget, an AI agent's spending decisions are rational when the budget forces explicit prioritization: it must choose which sources are worth paying for, when a cheaper source suffices, and when it has read enough to stop . Every purchase is then a reasoned trade-off, and the budget produces emergent frugality . A stable unit of account supports this reasoning by letting the agent price expected value against cost in stable terms, which is a precondition for rational spending decisions . The sources do not explicitly formalize maximizing total expected utility subject to the budget (Subclaim 1) or dynamic reallocation when costs/benefits change (Subclaim 4); the strongest supported elements are constrained choice, cheaper-source substitution, and stopping once additional reading is no longer worth paying for .
Evidence ledger — quotes verified before rewards
Rational spending decisions under a hard budget involve maximizing total expected utility subject to the constraint that total spending does not exceed the budget.
20%“Dollar stablecoins like USDC let an agent price expected value against cost in stable terms, which is a precondition for rational spending decisions.” [S1] Stablecoins as the unit of account for agents
Rationality requires evaluating each potential expenditure by its marginal benefit relative to its cost, prioritizing those with the highest benefit per unit of cost.
45%“An agent under a hard budget must choose: which sources are worth paying for, when a cheaper source suffices, and when it has read enough to stop.” [S5] Budgets make agents decide, not just automate
Rational decisions account for opportunity costs, meaning spending on one item foregoes the benefits of alternative uses of the same funds.
50%“every purchase is a reasoned trade-off, and the budget produces emergent frugality.” [S5] Budgets make agents decide, not just automate
Under a hard budget, rational agents must adjust their spending when costs or benefits change, reallocating resources to maintain optimal utility while staying within the budget.
