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

With no annotations, the description carries the full burden and does well: it specifies payment amount and recipient, HTTP 402 for unpaid requests, JSON response after valid X-PAYMENT, and the newest-vs-older chunk pagination behavior. This gives an agent concrete expectations beyond the schema.

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 packs many facts (payment location, resource, pricing, HTTP status, pagination) into a dense paragraph with mixed sentence fragments. It is not front-loaded by purpose and contains the crypto address that is likely irrelevant for agent invocation. A structured breakdown would be easier to parse.

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?

For a paid tool with 4 optional params and no output schema, the description covers the essential operational quirks: payment requirement, 402 failure mode, JSON success mode, pagination, and the official-text use case. It omits specifics of the JSON body, but there is no output schema, so an agent would only know it returns JSON. That's likely sufficient.

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 descriptions already provide 100% coverage with clear explanations for id, page, before, and x_payment. The description adds cost semantics (id costs $0.02, page/before cost $0.05) and clarifies the 'same URL' behavior, which enriches but does not contradict the schema.

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?

States a specific verb and resource: GET USDA APHIS AWA inspection-report observation text. Also clarifies the paid chunks and official text retrieval. However, it never contrasts with sibling tools like ticks or get-one, so an agent cannot tell when to pick this one based on the description alone.

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?

No when-to-use guidance exists. The description gives endpoint behavior and pricing but does not say when this tool is the right choice versus sibling tools, nor does it mention any alternatives or exclusions. The 'Not a new SKU' hint is cryptic and does not constitute usage direction.

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