Signed settlement-receipt verdict for a tx hash (PAID $0.01)

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare it is not read-only, is open-world and non-idempotent. The description adds genuinely useful context beyond that: the call is paid (0.01 USD via x402 on eip155:8453) and routed to POST /v1/settlement/receipt, so the agent knows a charge is incurred. However it never explains what side effect makes readOnlyHint false (e.g. minting/persisting a receipt) or what authorization is needed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short and front-loads the purpose, but the first line duplicates the title verbatim at zero informational gain, and the route/pricing detail is expressed in dense shorthand without explaining what a caller must do to satisfy the payment.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described, but for a paid, non-idempotent, open-world tool with six undocumented parameters the description leaves the agent unable to construct a correct call or understand what the verdict attests.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All six parameters have zero schema description coverage, and the description only illuminates txHash implicitly via the phrase 'for a tx hash'. The meaning and format of payee, payer, receipt, minConfirmations, and expectedAmountAtomic (especially atomic units) remain entirely undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description says it returns a signed settlement-receipt verdict for a tx hash, which is a concrete verb+resource, but the sentence is a verbatim restatement of the title and offers no differentiation from close siblings such as v1_receipts_mint, v1_bureau_receipt_check, or v1_settlement_conditional.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no statement of when to call this versus the many sibling receipt/settlement/verification tools, and no prerequisites or exclusions are given. The only context is the payment mechanism, which is not usage guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
