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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the description is not burdened with disclosing safety. It adds some behavioral context by listing return fields (title, authors, venue, citation count, abstract preview, full-text link) and noting conditional availability ('if available'). However, it does not mention rate limits, pagination, or potential result variability, leaving the behavior only partially transparent.

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 description is three sentences, each with a distinct purpose: stating the action, detailing the return fields, and advising on usage. It is front-loaded with the primary purpose and contains no redundant information.

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?

Given the tool's simplicity (two parameters), the description covers the essential return values and usage context. It lacks details on pagination, rate limits, or how max_results affects results, but these are not critical for a straightforward search tool, and the annotations handle safety and open-world semantics.

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?

The input schema already provides 100% coverage for both parameters (query and max_results) with clear descriptions. The tool description does not add any additional meaning about parameters beyond what the schema states, so the baseline score of 3 is 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 clearly states the tool queries Google Scholar for academic papers, citations, and research articles, with a specific verb ('Query') and resource ('Google Scholar'). It distinguishes itself from the sibling tool search_arxiv by covering all disciplines rather than just arXiv, and specifies the type of results returned.

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 provides clear usage context ('Use for comprehensive literature searches, citation tracking, or finding highly-cited works'), which implies appropriate scenarios. However, it does not explicitly mention alternatives or when not to use this tool, though the sibling tool search_arxiv is an obvious alternative for arXiv-specific searches.

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