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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: it does not explain the batch ceiling (100 IDs), what happens when claims are unavailable, or how replaceByRelated fallback surfaces in results, all of which are behavioral traits an agent would want.

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 opening sentence is clean, but the body degenerates into a keyword salad that repeats 'claim translation', 'patent claim translation', 'patent translation' and 'Nexscope' redundantly. The trigger phrase list bloats the definition without adding selection signal.

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 read-only retrieval tool with full schema coverage and annotations, the definition is adequate to get an agent to call it. It still leaves gaps: no indication of what the response contains (per-patent claim text blocks?) or how missing translations are reported, though the absence of an output schema makes some of that unavoidable.

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 fully documented in the schema. The description only echoes the supported languages (Chinese, English, Japanese) and adds no precedence or fallback nuance beyond what the schema already states.

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: retrieves translated patent claims from the Nexscope patent database. The word 'translated' distinguishes it from the plain nexscope_patent_claims sibling, but no sibling is named explicitly and the remaining workspaces of translation tools are not distinguished.

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 trigger list describes contexts of use (asking about claims, viewing claims in Chinese/English/Japanese, querying by patent ID or publication number) and even says to trigger without explicit mention of translation. However, it names no alternative tool and gives no exclusions, e.g. when to use nexscope_patent_claims or nexscope_patent_description_data_translation instead.

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