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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is known. The description contributes nothing beyond that — no note on translation latency, language coverage, batch limits, or what happens when a claim is unavailable (even though replaceByRelated exists as a parameter).

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 shortness alone does not earn credit here: the single sentence merely echoes the name and title rather than front-loading any actionable information. Nothing is wasted because nothing is said.

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 carry the burden of explaining what is returned (translated claim text? structured claim tree? language of source?), and it does not. An agent cannot tell how this differs from the non-translated claim tool or from patent_claims_translation, making the definition insufficient for confident selection.

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 all four parameters (lang, patentId, patentNumber, replaceByRelated) are already documented in the schema with defaults and constraints. The description adds no parameter meaning on top, so the baseline 3 applies rather than higher.

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 is a verbatim restatement of the title ('Patent Intelligence ZY: claim Data Translated API') with no adding verb or resource framing. It hints at translated claim text but never states whether it retrieves, translates, or submits claim data, and gives no way to distinguish it from near-identical siblings like nexscope_data_zy_claim_data or nexscope_patent_claims_translation.

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?

No when-to-use, when-not-to-use, or alternative routing is given at all. In a family containing nexscope_data_zy_claim_data (non-translated) and nexscope_patent_claims_translation, the absence of any guidance is a real cost, though the text is not actively misleading.

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