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

With no annotations provided, the description carries the full burden of behavioral disclosure and does so thoroughly. It reveals that unpaid requests return HTTP 402, that a valid X-PAYMENT is required, that the same URL then returns JSON, and that pagination works via chunk markers (newest/older/since). It also discloses pricing per call and the payment destination. This is substantial transparency beyond a simple 'retrieve document' statement.

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 front-loaded with the URL and price, and each of the six sentences conveys a distinct fact (payment, scope, pagination, error behavior). It is relatively compact given the amount of information. However, the phrase 'Not a new SKU.' adds jargon and is somewhat redundant with the schema's 'same door, not a new SKU', slightly undermining clarity.

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?

The description covers payment, error codes, pagination modes, and the fact that a successful response is JSON. However, there is no output schema, and the description only says 'returns JSON' without describing the JSON structure or fields. An agent would not know how to parse the response to extract the actual decision text, which is a meaningful gap for a document-retrieval tool. More detail about the return shape would be needed for full completeness.

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% and each parameter already has a detailed description including pricing and pagination semantics (e.g., id is $0.02, before is 'another $0.05'). The tool description adds little beyond reinforcing the ?id= and ?since/?before patterns already in the schema. Since the schema does the heavy lifting, the baseline 3 is appropriate.

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 explicitly identifies the resource as 'DOL OALJ / BALCA / ARB Decision and Order text' and the action as a GET that can retrieve a specific official text via ?id=. This clearly distinguishes it from the many sibling agency-decision tools (e.g., epa-alj, fmshrc-orders) by naming the exact collection it serves. The core purpose is stated with a specific verb (GET) and a specific resource.

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 provides clear context for when to use this tool: it is for DOL OALJ / BALCA / ARB decisions, which is implicit guidance for selecting among siblings. It also details several usage modes (plain GET for newest chunk, ?before for older, ?since for newer than a watermark, ?id for a single text) and the payment requirement. However, it does not explicitly name alternatives or state when NOT to use it, so it falls short of a 5.

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