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

Annotations declare readOnlyHint=false and openWorldHint=true, so the open-world nature is covered. The description adds nothing: no mention of quota/cost for an external patent API, no note that readOnlyHint=false despite a query-style operation (likely billing), and no pagination or result-size behavior for a 20,000-record window.

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 one sentence is not verbose, but it is under-specified rather than concise. There is nothing front-loaded beyond a label the agent already sees in the tool name.

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 9-parameter, no-output-schema, open-world search API, the description supplies nothing an agent could use to decide between it and the many patent/database search siblings. The rich schema covers parameters but not purpose or selection context.

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 9 parameters, including sort fields, deduplication modes, and queryText syntax, are documented in the schema itself. The description adds no meaning beyond that, which lands at the baseline of 3.

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 the title restated: 'Patent Intelligence ZY: query Search Patent API.' It conveys only that a patent search happens, with no statement of scope, data source, or coverage. It gives an agent no basis to distinguish it from siblings such as nexscope_patent_search, nexscope_data_patents_search, or nexscope_google_patent_search.

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 when-to-use, when-not-to-use, or alternative-selection guidance anywhere in the description. With dozens of patent-related siblings, the absence of routing information leaves the agent to guess.

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