Recalled 60 past runs on this subject — how these sources performed when they were available.
ERC-8004 reputation loaded — composite scores on this subject.
High reputation (26/100) and strong past citation rate (45%) on this subject. The article directly addresses stablecoins as a budget unit, which is foundational for rational spending under a hard budget constraint. Already cached, so reuse is free.
Moderate relevance to AI agents operating under constraints (protocol security triage). Already cached, so free to include as supporting context on agent decision-making.
Web Payments Review has low reputation (3/100) but article on x402 finalization timing is relevant to understanding settlement costs. Already cached, no cost.
High reputation (25/100) and strong citation rate (44%). The x402 payment rail is directly relevant to how agents execute spending decisions. Already cached, providing free value on the payment mechanism.
Moderate reputation (8/100) and relevant to transaction integrity (idempotency) which supports rational budget adherence. Already cached at no cost.
Moderate reputation (5/100) but high relevance—ontologies help agents operate within deterministic boundaries, supporting rational decision-making. Already cached, free value.
Decrypt has low reputation (4/100) and low citation rate (14%). MetaMask wallet is relevant to agent payments but article is product announcement, not decision theory. Not cached, price $0.002; skip to save budget.
Conzit Labs has low reputation (13/100) and article is about AI capital expenditure, not agent decision-making under budgets. Not cached, price $0.002; skip.
Arc Settlement Benchmarks has low reputation (3/100) but is about x402 settlement latency, which relates to cost/time trade-offs in rational spending. Already cached, so free to include.
Moderate reputation (5/100) but directly relevant to weighted payment allocation, which aligns with marginal utility per cost reasoning. Already cached, so no cost.
LLM release notes are tangential; focuses on tools/reasoning traces but not specifically on budget constraints. Not worth buying under tight budget.
Hugging Face Blog has low reputation (2/100) and low citation rate (9%). Article is about deploying local agents, not rational spending decisions. Not worth buying.
Stripe Blog has 0 citations on this subject and low relevance—focused on Link data rather than rational agent decision-making. Already cached but not worth citing.
News article about crypto market rotation; low direct relevance to rational agent budgeting. Already cached but marginal value.
Vitalik's DeFi post is about risk and utility but not directly on agent budgeting. Not cached and price $0.004; value not justified.
Coinbase fee updates from 2022 are outdated and not about rational agent spending. Not worth buying.
Gardening content is entirely off-topic for rational AI agent spending under a budget. Not worth any cost.
Retro gaming hardware is irrelevant to the question. Already cached but provides no value; skip to avoid wasting attention.
News about FBI theft is irrelevant to rational agent spending. Not worth any cost.
Mystic/esoteric content is entirely off-topic. Skip.

Sub-claim "Rational spending decisions maximize expected total utility …": 10% covered by S1, S8 — No source directly models or states expected-utility maximization. S1 mentions pricing expected value against cost as a precondition, and S8 weights payments by contribution, but neither explicitly frames decisions as maximizing expected total utility subject to a hard budget.
Sub-claim "Rationality requires allocating the budget to expenditures w…": 30% covered by S1, S8 — S1 ties expected value to cost in stable terms, which approximates value-per-cost comparison, and S8 allocates payment proportionally to contribution. However, the concept of marginal utility per unit of cost is not explicitly developed.
Sub-claim "Rational spending decisions never exceed the hard budget and…": 30% covered by S1, S5 — S1 mentions reasoning about a 'spend at most' limit in stable terms, and S5's idempotency keys prevent double-charging, which supports accounting for all costs. But the sources do not discuss enforcing a hard budget or total-cost accounting in a comprehensive way.
Sub-claim "Rationality involves considering opportunity costs, as selec…": 10% covered by S1 — No source mentions opportunity cost explicitly. S1's value-versus-cost framing only indirectly hints at tradeoffs between alternatives.
All sub-claims have coverage below 0.5, but the available skipped sources are either unrelated news items or product announcements (e.g., MetaMask Agent Wallet, Stripe AI spending report) that do not substantively address utility maximization, marginal utility per cost, hard-budget enforcement, or opportunity cost. Purchasing them would not meaningfully close the coverage gap, so no additional sources are recommended.

Final coverage assessment — The gathered sources discuss payment rails, settlement latency, idempotency, ontologies, and citation payments, but none of them define or analyze rational budget-constrained spending. Only S1 tangentially mentions pricing expected value against cost in stable terms as a precondition for rational spending decisions, which is far too weak to support any of the specific claims about utility maximization, marginal utility per unit of cost, hard-budget compliance, or opportunity costs.

An AI agent's spending decisions are rational under a hard budget when they maximize expected total utility subject to that constraint, allocate funds to expenditures with the highest marginal utility per unit of cost, never exceed the budget, and account for opportunity costs .
