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

The description discloses a paid USDC settlement and says x402-aware clients can 'authorize and settle inside this tool call,' which implies financial side effects. This contradicts the annotations readOnlyHint=true and idempotentHint=true, since settling a payment is not read-only and repeated calls would incur repeated charges. Annotation contradiction.

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?

The description is two sentences and front-loads the cost and batch scope. It is compact, but the phrasing 'using unpaid MCP and x402/HTTP evidence' is dense and could be clearer without much added length.

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?

With no output schema, the description should explain what the tool returns or what 'verified resolve' produces, but it does not. It also omits failure modes, payment failure handling, and how the evidence is used. The batch count and chain info are useful, but the missing output and parameter context leave an agent under-informed.

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?

Schema description coverage is 0% and the description does not explain the semantics of the 'goal' or optional 'url' fields. It only repeats the 2–4 count already present in minItems/maxItems and introduces 'capability decisions' without defining what those are, so it fails to compensate for the undocumented parameters.

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 states a specific action: batch live verification of 2–4 capability decisions, and adds concrete context (paid $0.05 USDC, Base/Solana, unpaid MCP evidence). It distinguishes itself from the singular verified_resolve and resolve siblings via the word 'batch' and the explicit count range, though it does not name those alternatives.

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?

The description gives a clear usage context: use for 2–4 capability decisions and for paid batch verification with x402/HTTP evidence. However, it does not explicitly say when to prefer another tool, such as verified_resolve for a single decision, nor does it state exclusions or prerequisites beyond the count.

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