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

With no annotations, the description carries the full behavioral burden and does disclose meaningful traits: a paywall with a specific price, HTTP 402 for unpaid requests, JSON returned only after a valid X-PAYMENT header, and 304/recordCount 0 for empty result sets. It omits rate limits and response shape, but the payment/auth and status-code behavior is unusually well covered.

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?

It is short, but dense and cryptic, packing a raw URL, wallet address, and repeated price tags into run-on fragments. The wallet address is legitimately needed, yet phrases like 'Not a new SKU' and duplicated '$0.05' clauses add noise rather than 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, no-annotation, no-output-schema GET endpoint, the description is fairly complete: it covers pricing, payment/auth mechanism, mode selection, and error behavior. The main gap is that it never describes the JSON payload beyond 'returns 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 schema already documents all five parameters, making 3 the baseline. The description adds per-parameter pricing and notes that 'page' is ignored when since/before is set, but mostly it restates the schema's own parameter semantics, so no lift above baseline.

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The description states a specific resource: MSPB nonprecedential and precedential decision text, retrieved via GET. That distinguishes it from the many sibling agency-decision tools (nlrb-decisions, flra-decisions, etc.). However, the actual verb is buried inside the raw URL string rather than stated cleanly, and the sentence is padded with payment mechanics, so it is clear but not crisp.

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 parameter-level routing (plain GET = newest chunk, ?before = older chunk, ?since = newer-than-watermark, ?id = one official text), which tells an agent how to pick a mode. But it offers no tool-level guidance about when to use this versus sibling tools such as search or get-page, so usage is only implied at the selection level.

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