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

With no annotations, the description carries the full behavioral disclosure burden. It clearly states the payment requirement ($0.05/$0.02 USDC on Base to a specific address), the unpaid HTTP 402 response, and that a valid X-PAYMENT makes the same URL return JSON. It does not mention rate limits or detailed response structure, but the critical paid-access behavior is transparent.

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 dense and mostly information-dense, but it is a single paragraph with semicolon-separated pricing rules and unexplained jargon like 'chunk', 'watermark', and 'SKU'. It is not bloated, but structure and plainer wording would improve 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?

For a paid 5-parameter endpoint with no output schema and no annotations, the description covers payment, modes, and error behavior but does not explain the JSON response structure beyond saying it returns JSON. The schema provides hints like recordCount, but the missing return-shape detail is a noticeable gap.

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?

The input schema already provides rich descriptions for all 5 parameters, so the baseline is 3. The description adds the base URL, wallet address, and default pricing for a plain GET, but the semantic meanings of id, page, since, before, and x_payment are already well covered in 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 identifies the resource as FLRA Authority Decision text and the operation as a paid GET, with distinct modes for a single official text (?id), newest chunk, older chunk (?before), and newer-than-watermark (?since). It is clear about the subject matter but does not explicitly differentiate this tool from the many agency-specific sibling tools.

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 usage rules for each mode: plain GET for the newest chunk, ?id for one official text, ?before for older chunks, and ?since for newer texts, with per-mode pricing. It does not discuss when to prefer a sibling tool, but the parameter-level guidance is concrete and actionable.

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