What is easy to misunderstand about infrastructure for multi-step agent tool use, and what does the evidence actually show?

The supplied sources do not directly state what is "commonly misunderstood" about infrastructure for multi-step agent tool use, so that part of the question is unanswered by the evidence provided. What the evidence does show is that multi-step agent infrastructure is treated as a set of separable, verifiable stages rather than a single opaque action: the Keryx buyer client separates quoting, buying and recovering a research job , and its recovery path sends only GET requests for the original job without signing a new authorization or replaying a purchase . The evidence also shows that payment evidence and content delivery remain separate, and that a retained success response with a Circle reference is labeled seller-reported settlement rather than an independent Circle query or on-chain finality proof . Relatedly, an unknown order or expired authorization does not prove that a payment failed, and deleting the journal and buying again can create a second debit . On the agent-loop side, the evidence shows ontologies being used as guardrails around probabilistic LLM loops, described as "a bounded set of rules around an unbounded loop". The sources do not otherwise describe a specific common misunderstanding about multi-step agent tool infrastructure, so no citation is offered for that portion.

Free-preview pre-check maps an actionable source to every sub-claim (2/2); paid reading may proceed within the budget.
Agent Economy Weekly is the most-cited source on this subject (19/31 runs, 61%) and its preview directly frames x402 as the payment rail agents use inline — the kind of infrastructure claim that is often oversold as 'agents just pay and go', which speaks to claim 0's misunderstanding and claim 1's evidence. Already cached, so reuse is free. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Latent.Space's 'Ontologies Are So Back' argues agents need deterministic boundaries to contain probabilistic behavior — a direct counterpoint to the common misconception that multi-step tool use 'just works' (claim 0) and a substantive evidence source (claim 1). 6.8KB full-ish text, cached, high per-citation weight historically. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Ethereum Foundation's post on running coordinated AI agents against protocol code is a real-world account of multi-step agent workflows and what holds up under scrutiny — useful for claim 1 (what the evidence actually shows) and for puncturing over-optimistic assumptions in claim 0. Cached, so free. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Keryx first-party engineering notes (full text, 3KB) describe how a paid research job is quoted, journaled and resumed without a second payment — a concrete multi-step agent workflow where naive assumptions about idempotent, resumable tool calls break. Relevant to claim 0's misconception and claim 1's evidence; cached, so free. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Stablecoin Ledger has the best reputation here (50/100) but its preview is about USDC instant settlement finality on L2s — a payments-rail fact, not about what is misunderstood in multi-step agent tool-use infrastructure. No valid target, so skip despite quality.
Onchain Micropayments Digest (25% citation rate) previews nanopayment floors and batching — a settlement-cost detail, not evidence about multi-step agent tool-use infrastructure. Weak fit for either sub-claim.
Distributed Systems Notes is low-reputation (6/100) but its idempotency-keys preview is a concrete, commonly-missed reliability requirement for multi-step tool calls and retries — directly relevant to what people misunderstand (claim 0) and what the evidence shows about safe retries (claim 1). Free to reuse since cached. — cached bytes are free, but this read does not clear the attention gate (EV 0.40, minimum 0.45, with a required claim target).

Retro console recapping; no connection to agent infrastructure or payments.
Stripe Blog has decent reputation (38/100) but this piece is about evidence packets in card 'product not received' disputes — a payments-dispute topic, not multi-step agent tool-use infrastructure. No valid target.
Cointelegraph market-recap piece on Bitcoin's rebound and crypto stocks; no bearing on agent tool-use infrastructure.
Simon Willison's 'Feeling sad about AI' is metadata_only with zero plaintext bytes, so no preview evidence can be assessed; not worth a paid read under this budget.
Hugging Face agent-memory post is metadata_only (0 bytes) — title alone doesn't establish relevance to multi-step tool-use infrastructure, and it's not cached.

Coinbase's Web3 identity post (2022) concerns wallet/identity UX, not multi-step agent tool-use infrastructure.

Arc Settlement Benchmarks gives measured x402 settlement latency/finality — concrete evidence for claim 1 about what the infrastructure actually delivers versus assumptions, though its low reputation (16/100) and narrow settlement focus limit value. Cached, so free. — cached bytes are free, but this read does not clear the attention gate (EV 0.35, minimum 0.45, with a required claim target).
Web Payments Review's x402 finalization timing overlaps Arc Benchmarks and Stablecoin Ledger; redundant and lower reputation (13/100), and only tangentially about multi-step tool use.

Final coverage assessment — The question asks what is easy to misunderstand about infrastructure for multi-step agent tool use and what the evidence actually shows. The supplied sources are largely abstracts or first-party engineering notes. S4 (Keryx buyer recovery) directly addresses a multi-step agent workflow (quoting, buying, recovering a paid research job) and identifies several common misunderstandings: that an unknown order or expired authorization proves payment failed; that deleting the journal and buying again is safe; that a retained success response with a Circle reference is independent settlement proof; and that missing creator accounting can be treated as zero. It also states what the evidence actually shows: resume sends only GET requests and does not replay a purchase; deleting the journal can create a second debit; payment evidence and content delivery remain separate; a Circle reference is seller-reported settlement, not an independent Circle query or on-chain finality proof; and missing accounting must not be silently turned into zero. S1 describes x402 payment rails but does not discuss misunderstandings or evidence about multi-step agent tool-use infrastructure. S2 discusses ontologies and neurosymbolic guardrails for agent loops, but the excerpts do not identify common misunderstandings or present evidence about infrastructure for multi-step agent tool use. S3 is only an abstract noting coordinated AI agents against protocol code, with no substantive answer. Thus the first sub-claim is partially answered by S4, and the second sub-claim is partially answered by S4, but the evidence is limited to one first-party source and does not broadly establish what the evidence shows across the field. The assessment does not establish a complete supported answer for every requested part.
