verify_paper

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

No annotations are provided, so the description must convey behavioral traits. It indicates a read-only verification operation, but does not disclose what happens if no match is found (e.g., error vs. false return), authentication needs, or rate limits. The output schema exists but is not referenced.

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 a single, clear sentence with no wasted words. However, it could be structured to better separate identifier options and add brief usage context without significant expansion.

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 5 parameters, no annotations, and an output schema, the description is too minimal. It fails to explain what 'verify' returns (boolean? paper details?), how to combine identifiers, or any prerequisites. The output schema existence does not compensate for missing behavioral and semantic 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 0%, so the description must explain parameters. It mentions DOI, arXiv ID, and fuzzy title match, covering 3 of 5 parameters, but omits 'authors' and 'year'. The description does not clarify how multiple parameters interact (OR vs AND) or which are sufficient.

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's purpose: verify a paper's existence via specific identifiers (DOI, arXiv ID, or title). It distinguishes from sibling tools like add_paper, remove_paper, and search_papers by focusing on existence verification.

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 implies usage for checking if a paper exists, but does not explicitly state when to use this tool versus alternatives (e.g., search_papers) or provide conditions for use (e.g., when you need to confirm existence before acting). No exclusions or when-not guidance.

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