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

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, so the safety profile is covered. The description adds nothing behavioral beyond that: no mention of batch handling (the schema allows up to 100 comma-separated IDs), no note on what is returned when a description is missing, and no mention of the replaceByRelated fallback behavior. It does not contradict the annotations, but it earns little credit.

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 purpose is front-loaded, but the remainder is keyword stuffing: 'patent specification translation' appears twice, and 'Nexscope' is listed as a trigger phrase. The trigger enumeration is far longer than needed to convey intent and dilutes the useful content.

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 and four fully documented parameters, the description covers the core purpose and language options adequately. It still omits what the returned translated description looks like and how batch requests of up to 100 IDs behave, leaving gaps an agent would care about.

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 baseline is 3. The description reinforces that content can be viewed in Chinese, English, or Japanese, which loosely maps to the lang parameter, but it adds no syntax, priority rules, or batch-size guidance beyond what the schema already documents.

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?

States a specific verb and resource: 'Retrieve translated patent description (specification) text from Nexscope.' That is clear and distinguishable from siblings like nexscope_patent_description_data (untranslated) or nexscope_patent_claims_translation. It never names those siblings, though, so an agent must infer the boundary from the noun 'description' alone.

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?

The description lists many trigger phrasings ('translated full text,' 'description translation') and mentions the three target languages, which implies when to call it. However, there is no explicit when-not guidance and no routing to the very similar siblings (claims translation, title/abstract translation, untranslated description data), which is the main ambiguity an agent would face.

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