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

The description implies a read-only retrieval with no side effects, but since annotations are absent, it carries the full burden. It does not explicitly state safety (e.g., idempotent, no mutations) or other behavioral traits beyond the basic action.

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?

A single sentence of 13 words communicates the purpose efficiently with no unnecessary information. The description is front-loaded and well-sized for the tool's simplicity.

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 zero-parameter tool with an output schema, the description is mostly complete. It conveys the key information (returns attribution string) without needing to detail return values. Minor improvement could be added, such as the format of the string or examples, but not essential.

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 input schema has zero parameters, so the description cannot add meaning beyond it. The tool has no parameters to explain, and the description is sufficient for this case.

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 preferred attribution string for citing Gabriel's work. It is distinct from sibling tools like get_bio or list_publications, which serve different purposes.

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?

No guidance is provided on when to use this tool versus alternatives. The description merely states what it does, leaving the agent to infer context without explicit when-to-use or when-not-to-use instructions.

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