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

No annotations provided; description only mentions return structure. Does not disclose authentication, rate limits, or other behavioral traits. For a simple data lookup tool, this is minimal.

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?

Extremely concise: two sentences, first stating purpose, second showing return structure. No wasted words.

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?

Despite no parameters and simple output, description could elaborate on the fields within the returned objects (e.g., legalAge, license.name). Only demonstrates countries, but mentions others. Incomplete for thorough understanding.

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?

No parameters exist, so parameter semantics are not needed. Description adds sample return but schema coverage is 100% via empty schema. Baseline 4.

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?

Clearly states it returns reference enums (countries, currencies, occupations) with sample return structure. Distinguishes from sibling tools like pinnacle_matchup which handle sports data.

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?

Description implies it is for looking up valid enum values, but does not explicitly state when to use or when not to use. No mention of alternatives or context.

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