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

Annotations already indicate this is a safe, read-only, idempotent operation, so the description does not need to repeat those safety traits. It adds useful behavioral context by noting that the abstract is present for only ~51% of references, which is a data-quality caveat. It also explains the scope of the record, giving the agent an idea of what to expect without describing error handling or rate limits.

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 sentence that opens with the key purpose ('Full bibliographic record for one academic reference (by id)') and then efficiently lists the included components. Every word adds value, with no redundant phrases or filler. It is well-structured and easy to parse quickly.

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 tool with a single parameter and no output schema, the description sufficiently covers what the tool returns by enumerating the record components and the abstract availability caveat. It does not mention the response format or error cases, but these are not critical for such a simple read operation. The description is appropriately complete given the tool's complexity.

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?

The schema has one parameter, reference_id, with type integer and bounds, but has 0% schema description coverage. The description compensates minimally by saying 'by id', clarifying that the parameter is the reference's identifier. However, it does not explain how to obtain a valid id or any other nuances. Given the parameter's self-explanatory name and the 'by id' hint, the description provides baseline but not rich semantic value.

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 returns a full bibliographic record for one academic reference by id, explicitly listing included fields such as abstract, subjects, DOI/URL, and host-work details. This distinguishes it from sibling tools like get_article or get_document, which target different resource types. The scope is specific and 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 used when a complete record for a single reference is needed, especially when the reference_id is known. However, it does not explicitly state when to prefer this over alternatives like get_article or get_document, nor does it mention any exclusions or prerequisites. The usage context is inferred rather than directly explained.

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