B3.3/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that the tool displays rates, which implies a read-only operation, but it does not describe the output format, any coverage limitations, or clarify the ambiguous parenthetical. This is a basic but not richly transparent description.

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

Conciseness4/5

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

The description is a single, front-loaded sentence that efficiently states the tool's purpose. The parenthetical addition adds some ambiguity, which slightly detracts from the otherwise concise structure.

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

Completeness3/5

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

The tool is simple with no parameters and no output schema, so the description is mostly sufficient. However, the meaning of 'major trading partners' is unclear, and the description does not describe the output format or explicitly confirm that it returns a complete reference table. These gaps lower the completeness score.

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

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters, and the schema is empty, so no parameter information is needed. The description adds no parameter semantics, but with no parameters, the baseline score is 4.

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

Purpose4/5

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

The description uses a specific verb 'Display' and identifies the resource 'withholding tax rates for all countries' in Canada's tax treaty network, which clearly distinguishes it from the sibling 'treaty_rate_lookup'. However, the parenthetical '(major trading partners)' creates ambiguity about whether the table covers all treaty countries or only a subset, slightly reducing clarity.

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

Usage Guidelines2/5

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

The description provides no explicit guidance on when to use this tool versus alternatives like 'treaty_rate_lookup'. While the scope 'all countries' implies an overview use case, there is no stated when-to-use/when-not-to-use or mention of alternatives.

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