gold402_verdict

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false. The description adds meaningful behavioral context beyond those: the $0.001 USDC payment, the two-call settlement flow, and the fact that the server never holds a wallet. No contradiction with annotations.

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 dense but efficient: it front-loads the paid nature, defines the output, distinguishes the tool from a sibling, and explains the two-call flow in four short sentences. Minor redundancy with schema text on payment_signature costs it a point.

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?

Given the output schema exists and the main behavioral complexity is the payment handshake, the description is largely sufficient. It explains what the verdict contains, how to pay, and what makes it different from the free check. It does not mention the markdown response_format option, but that is visible in the schema.

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?

The description adds useful meaning about the payment_signature workflow and the resource scope, but the schema already documents resource and payment_signature semantics. The claim that output is 'as JSON' is potentially confusing because response_format defaults to markdown and allows json, and response_format is not discussed in the description.

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 names a specific, differentiated purpose: 'the 24K Labs editorial verdict for one x402 resource, plus aggregated independent rater grades.' It also explicitly contrasts with gold402_check_endpoint, making the tool's role clear among its siblings.

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?

It gives concrete usage guidance: call once without payment_signature to receive payment terms, then call again with the signature to settle. It explicitly distinguishes from the free gold402_check_endpoint, though it does not address when to choose this over gold402_search, list_sections, or get_entry.

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