A3.8/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds behavioral context by mentioning 'shared transport reuse' and 'optional cross-host concurrency,' which are not present in the schema. It does not disclose failure behavior or response shape, but those are not required by the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one dense sentence with no filler, front-loaded with the core action and batch scope. Every clause contributes either resource identification or behavioral context.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool accepting up to 50 queries with no output schema, the description leaves out return format, per-item failure semantics, and any distinction from batch siblings. It is adequate for understanding the basic operation but not fully complete for invoking it safely at scale.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

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 by explaining that queries can be DOIs, URLs, or titles and that concurrency is optional and cross-host. However, it omits the array-size limits and the concurrency range (1–8), leaving the schema to fill those gaps.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb ('Resolve') and a clear resource ('multiple DOI, URL, or title queries'), and explicitly signals batch scope with 'multiple' and 'cross-host concurrency.' This distinguishes it from single-resolution siblings like resolve_paper.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The word 'multiple' implies the tool is for batch resolution, but the description never states when to prefer it over sibling tools such as resolve_paper or batch_fetch, nor does it provide any exclusions or when-not-to-use guidance. Usage is implied rather than explicit.

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