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

Annotations mark this as non-read-only and open-world, which is unusual for a search endpoint, and the description supplies nothing to clarify cost, rate limits, result shape, or consequence. The agent learns nothing about behavior beyond the annotation flags.

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 only because it is under-specified rather than efficient; the single sentence conveys no verb-target-scope information an agent can act on.

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 17 parameters, no output schema, and an ambiguous annotation profile, the description should explain scope and result behavior. It does none of that, leaving the agent to infer everything from parameter names.

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%, and every one of the 17 parameters carries its own description (advanced query syntax, date format, pagination, dedup). The description adds no parameter meaning, but the baseline applies because the schema does the work.

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 merely restates the title ('Google Research Tools: search API') and never says what is being searched or that this queries Google Patents. Only the tool name and schema parameters reveal the resource, so the description itself is tautological.

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 indication of when to use this tool versus the many patent siblings (nexscope_google_patent_search, nexscope_patent_search, nexscope_data_zy_query_search_patent). No prerequisites, query expectations, or exclusions are stated.

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