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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is known. The description adds useful behavioral context by listing returned fields (titles, authors, publication info, citation counts, PDF links) and clarifying the cites/cluster modes, which goes beyond the annotations without contradicting them.

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?

Three succinct sentences with no filler. The core purpose comes first, return content is stated next, and the cites/cluster/case-law guidance is packed into the final sentence efficiently.

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 search tool with 100% schema coverage and open-world annotations, the description is largely complete. It names the output fields and points to the correct alternative for case law; the only minor gap is that it does not describe pagination behavior, but num/page are already fully documented in the schema.

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 the schema already documents all 7 parameters. The description mentions cites and cluster at a high level, but doesn't add meaningful parameter semantics beyond the schema descriptions; this is the expected baseline 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?

Description specifies a clear action (Search Google Scholar), a precise resource (academic papers, citations, scholarly articles), and differentiates from the sibling google_scholar_cases. It also distinguishes this tool's scholarly focus from patent and news-oriented siblings.

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?

Provides explicit guidance for special modes: 'Use cites parameter to find papers citing a specific work, or cluster to find all versions of a paper.' It also names an alternative tool for court opinions and case law, telling the agent exactly when not to use this tool.

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