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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered by structured data. The description adds nothing beyond that — no mention of remote patent-database queries, latency, credit cost, or what the 'design patent' search actually compares.

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 brevity here is under-specification rather than conciseness — a single fragment that duplicates the title and leaves the substantive behavior unstated. Nothing is front-loaded because there is nothing informative to front-load.

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 10-parameter, open-world, image-based patent search with no output schema, the description is completely inadequate. It never explains what a design-patent image search returns (candidate patents, similarity scores, radar infringement assessment) or how queryMode/patentStatus affect results.

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 ten parameters (topLoc, regions, imageUrl, queryMode, topNumber, enableRadar, patentStatus, etc.) are already documented in the schema. The description contributes no additional parameter meaning, making the baseline 3 appropriate.

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 essentially a restatement of the tool name and title ('IP Risk Detection RG: detection Patent Design API'), with no actual verb or resource explained. An agent learns only that the tool relates to patent design in some IP-risk context, not what it does with the image or what it returns.

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 tool versus alternatives. Sibling tools such as nexscope_data_rg_utility_patent_detection, nexscope_design_similarity_search, or nexscope_data_zy_patent_image_search are plausibly competing choices, and the description does nothing to distinguish them.

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