Title and preview directly address both subClaims: 'Stablecoins as the unit of account for agents' is the article's focus, and the preview explicitly mentions 'Dollar-denominated stablecoins give agents a stable budget unit,' which speaks to USDC's role.

Re-evaluate

Sub-claim "What is the concept or context described as "Stablecoins as …": 90% covered by S1 — S1 directly answers this sub-claim: it describes autonomous agents needing a stable unit of account to reason about budgets, and that volatile tokens make price stability meaningless. This explains the context and concept. The abstract from S1 is sufficient; no additional context is required.

Re-evaluate

Sub-claim "According to that context, what specific characteristics, ro…": 70% covered by S1 — S1 explicitly states that dollar stablecoins like USDC allow an agent to price expected value against cost in stable terms, which is a precondition for rational spending decisions. This assigns USDC the role of providing a stable unit of account for agents' budgeting and rational decision-making. S2 does not mention USDC. The coverage is direct but could be slightly more detailed about USDC-specific characteristics (e.g., if the article had more on USDC's features). The gap is minor.

Re-evaluate

Both sub-claims are covered adequately by the existing sources, especially S1 which directly addresses the concept and the role of USDC. The first sub-claim has near-full coverage, and the second has a direct answer with only a small potential gap in additional detail. No additional sources from the skipped list appear relevant to these specific claims (e.g., they focus on payment rails, legal issues, or unrelated topics). The remaining budget is low, and buying more would not improve coverage on these specific claims.

Final check — "According to that context, what specific characteristics, ro…": 90% assessed by S1

Sufficiency

Final coverage assessment — The gathered sources provide a direct answer to the first sub-claim, explaining the concept and context. For the second sub-claim, the sources explicitly describe a specific role and implication for USDC, but they do not list multiple characteristics. The second source does not mention USDC or stablecoins in its excerpt, so it does not contribute to this claim. Coverage is assessed based solely on the supplied passages.
