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

With no annotations, the description carries the full behavioral burden and meets it well. It discloses the payment amount and target, the exact HTTP 402 behavior when unpaid, that a valid X-PAYMENT makes the URL return JSON, and how chunking works.

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 compact and front-loads the endpoint and pricing before moving through query modes. The run-on style and the 'Not a new SKU' phrase make it slightly less polished, but every sentence carries operational information.

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 no output schema, the description provides the essential contract: URL, payment requirement, 402 behavior, JSON after X-PAYMENT, and chunk semantics. It does not describe the JSON shape, but the schema already covers page, since, before, and x_payment behavior.

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 coverage is 100%, so the baseline is 3; the description adds cross-parameter context such as price per mode, plain GET being the newest chunk, and before/since acting as offsets from that chunk. This extra layering justifies a 4.

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 clearly identifies the endpoint and the resource (Copyright Claims Board Final Determination text) and distinguishes official text via id from chunked reads. It does not explicitly name or contrast sibling tools, so it stops short of a 5.

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 explicit routing guidance: plain GET for the newest chunk, ?id for one official text, ?before for older chunks, and ?since for entries newer than a watermark. It does not name alternative tools or say when not to use this tool, so it is clear but not maximal.

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