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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds genuinely useful behavioral context by disclosing a per-call charge and the x402 payment mechanism, but it never explains what x402 entails or what happens on payment failure, so the disclosure is a fragment rather than full guidance.

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?

Two short sentences, front-loaded with the purpose and then the cost. Nothing is padded, though 'Paid ($0.002, x402)' is compressed to the point of being cryptic rather than purely economical.

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?

With no output schema, the description must convey the return shape, and 'parsed reference list' is only a partial answer — no indication of fields, ordering, or whether references are limited/paginated. For a paid tool whose result is unstructured to the agent, this leaves real gaps.

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 the single 'id' parameter is already documented with its source tools and an example. The description adds nothing about the parameter, so the baseline 3 for schema-covered parameters applies.

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?

Names a specific resource ('reference list of one resource') and the modifier 'Parsed' signals the output is structured extraction rather than raw text, distinguishing it from get_fulltext or get_document. It stops short of explicitly contrasting itself with those siblings, so a 4 rather than 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?

There is no when-to-use guidance, no prerequisite (e.g. that the id comes from search_archive/get_catalog_page, which only appears in the schema), and no mention of alternatives such as get_fulltext for the body text. The only operational note is that the call costs money.

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