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

With no annotations provided, the description carries the full behavioral burden and it does well by disclosing payment requirements, HTTP 402 for unpaid requests, and the fact that the same URL returns JSON after a valid X-PAYMENT. It also communicates chunking behavior and empty-result behavior in the schema context, which is useful beyond a bare GET.

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 information-dense but somewhat run-on, mixing pricing, endpoint mechanics, payment behavior, and an odd 'Not a new SKU' phrase. It is front-loaded with the most important URL and cost information, but the phrasing is cryptic and could be cleaner.

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 GET tool with five parameters and no output schema, the description covers the critical operational context: payment flow, HTTP 402, parameter-specific costs, watermark behavior, and JSON response after payment. It leaves the JSON response shape undescribed, but enough is present for an agent to invoke the tool correctly.

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 baseline is a 3; the description adds extra meaning by attaching costs to each query mode and clarifying that these are not separate SKUs. It reinforces and extends the parameter semantics rather than merely repeating 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?

The description names a specific resource (FTC ALJ Decision / Commission Decision and Order text) and a concrete action (GET on a specific URL), so an agent can tell what the tool accesses. It does not explicitly contrast this tool with siblings like ftc-wl or cftc-orders, so it falls short of full differentiation.

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 gives clear operational guidance: plain GET returns the newest chunk, ?id returns one official text, ?before returns an older chunk, and ?since returns items newer than a watermark. It does not state when to choose a sibling tool, so it does not reach the full when-to-use-versus-alternatives standard.

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