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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds meaningful behavioral context beyond those annotations: it recognizes synonyms, accepts Italian or English terms, and returns definition, URL, related terms, and in-depth articles. No contradiction with annotations was found.

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 front-loaded and structured, starting with the core action and scope. However, the final English sentence essentially repeats the opening Italian sentence, adding redundancy without new semantic content. The additional details about synonyms and returned fields earn their place, but the duplication prevents a higher score.

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 low-complexity read-only lookup with only two parameters and no output schema, the description is reasonably complete. It names the resource, subject coverage, language handling, and the types of data returned. It does not explain behavior on missing terms or how results are ordered, but these are minor gaps given the simplicity and annotation coverage.

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 fully documents both 'term' and 'limit'. The description reinforces that the term can be in Italian or English and mentions synonyms, but it does not add meaning beyond what the schema already provides. Baseline 3 is appropriate here.

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 a specific verb and resource: 'Cerca un termine nel glossario odontoiatrico di bonebenders.com' and specifies the domain and categories. It is easy to understand this is a glossary lookup tool. However, it does not explicitly differentiate itself from the sibling tools bonebenders_read and bonebenders_search, so it stops short of a 5.

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: look up a dental term in Italian or English, and mentions synonym recognition and related articles. This gives useful context about when the tool is appropriate. However, it provides no explicit guidance about when to prefer this tool over bonebenders_read or bonebenders_search, and no exclusions are stated.

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