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

The description discloses no behavioral traits. Annotations are empty, so the description carries the full burden, and it fails to mention whether this is a read-only lookup, whether it returns a list or a single object, or any side effects. There is no contradiction with annotations, but there is also zero added value.

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 extremely short, but this is under-specification rather than conciseness. A single vague phrase 'Get the science' does not earn its place because it adds no information beyond the tool name.

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?

With no annotations, no output schema, and no parameter details, the description is completely inadequate. An agent cannot determine what this tool returns, what input it needs (even though there are 0 params, the meaning of the output is unknown), or how it relates to the sibling tools.

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 tool has 0 parameters, so the schema has nothing to document. The baseline for 0 params is 4, and the description does not need to add parameter meaning. It could have clarified what 'science' refers to, but parameter semantics are not a gap 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 is a tautology: 'Get the science' restates the tool name 'get_science' without any specific verb-resource detail. It does not distinguish this tool from siblings like get_canonical_sources or get_epi_definition, and provides no information about what 'science' means in this context.

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?

There is no guidance on when to use this tool versus alternatives. The sibling tools cover related scientific/epi concepts, but the description gives no context, exclusions, or selection criteria.

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