verify_paper

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It only states 'verify', which implies a read operation, but does not detail side effects, return format, or error handling. The presence of an output schema mitigates some lack, but the description itself is insufficient.

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 concise sentence that front-loads the key action and methods. Every word carries weight, with no filler or redundancy.

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 optional parameters and no annotations, the description is too brief. It does not address how parameters interact (e.g., combined usage), what happens on success/failure, or the output schema content. The presence of an output schema helps, but the description alone leaves significant gaps.

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 compensate. It adds meaning for 'doi', 'arxiv_id', and 'title' via 'DOI, arXiv ID, or fuzzy title match', but entirely ignores 'authors' and 'year' parameters. This incomplete coverage reduces clarity.

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 verb 'verify' and the resource 'paper', and specifies the methods (DOI, arXiv ID, or fuzzy title match). It effectively distinguishes from sibling tools like 'search_papers' (full search) and 'add_paper' (creation), making its purpose unambiguous.

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 that the tool is for confirming existence of a paper using identifiers, but it does not explicitly state when to use it versus alternatives (e.g., search_papers). It lacks guidance on when not to use it or prerequisites.

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