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

With no annotations provided, the description carries the full burden and does disclose important behavior: unpaid requests return HTTP 402, a valid X-PAYMENT is required, and the endpoint returns JSON after payment. It does not describe response shape, but it is transparent about the payment gate and error condition.

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 short and front-loads the URL, but it reads as a dense run-on with repeated pricing details and the cryptic phrase 'Not a new SKU.' It could be clearer if split into purpose, payment, and behavior sections.

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, paginated read endpoint with no output schema, the description covers the essential context: URL, cost, payment requirement, single-text vs chunk retrieval, watermark behavior, and the 402 failure case. The input schema fills in the remaining parameter semantics, and the response type is stated as JSON.

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 100%, so the input schema already documents all five parameters. The description repeats the id/before/since semantics and adds pricing, but it does not meaningfully expand on what the parameter descriptions already tell the agent.

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 identifies a specific resource, CFTC enforcement-order/settlement text, and a clear retrieval operation via GET, including single-text and chunked retrieval modes. However, it does not explicitly differentiate this tool from the many sibling regulatory-order tools, and the payment details clutter the core purpose statement.

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 guidance on when to choose cftc-orders versus alternatives like cfpb-orders, fdic-orders, or frb-orders. The description only explains query-mode variations and payment behavior, not tool-selection context.

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