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

Annotations declare readOnlyHint=false and openWorldHint=true; the description adds no behavioral context at all — no cost, rate limit, latency, auth requirement, or what the translation does to the payload. For a zero-content description, the full disclosure burden is unmet.

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 it is a single redundant sentence that duplicates the title rather than conveying information. Brevity here reflects under-specification, not efficiency.

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?

Four parameters, no output schema, and no explanation of what a 'claim data translated' response contains (claim text per language? structure? per-patent mapping?). The definition is far too thin for an agent to invoke it confidently.

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 lang, patentId, patentNumber and replaceByRelated are all fully documented in the schema (including precedence of patentId over patentNumber). The description contributes nothing extra, which is the baseline 3 case when the schema does the heavy lifting.

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/name ('Patent Intelligence ZY: claim Data Translated API') with no verb or statement of what the tool actually does. It weakly implies retrieving translated claim data, but an agent learns nothing about scope, source, or output beyond the label.

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 guidance on when to use this versus the obvious siblings nexscope_data_zy_claim_data (untranslated claims) or nexscope_patent_claims_translation. No prerequisites, no exclusions, no alternative routing.

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