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

With no annotations, the description carries the behavioral burden and does well: it discloses the return structure (exact/partial matches with programme, EU reference, and regulation link), the cost per call, and the human-review caveat. It does not cover rate limits or error behavior, but the key operational traits are present.

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 four tight sentences with the core action and scope front-loaded. Every sentence adds either purpose, return information, or usage caveat, with no wasted text.

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 two-parameter screening tool with no output schema and no annotations, the description provides enough context to call it: it explains what is screened, what is returned, and the human-review limitation. The remaining gap is the unexplained `type` parameter.

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 coverage is nominally 100%, but the `type` parameter's schema description is only "type" and is not clarified in the tool description. The description does add meaning for `name` by specifying a person or company and alias screening, but the second parameter remains semantically opaque.

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 states a specific verb and resource: screening a person or company name against the EU consolidated financial sanctions list, including aliases. It clearly identifies the tool's purpose and scope without needing a sibling comparison.

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?

It notes the tool is a screening aid and requires human review, which gives useful usage context. However, it does not explicitly state when to use this tool versus alternatives or when not to rely on it.

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