get_interest_by_region

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only states that data is 'retrieved', implying a read operation, but does not mention how results are structured, whether rankings are returned, or any caveats about geographic resolution or data availability.

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 a single, front-loaded sentence with no fluff or repetition. The phrase 'and other parameters' is somewhat vague and unnecessary, but it does not significantly harm conciseness.

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?

Given the 100% schema coverage and presence of an output schema, the description plus schema provides a minimally viable level of detail for invoking the tool. However, it lacks guidance for choosing among 15 siblings and gives no behavioral context beyond a basic retrieval statement, so it is adequate but not complete.

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 description coverage is 100%, so every parameter already has a meaningful description. The tool description adds no additional parameter semantics beyond 'keywords and other parameters', which is generic and unhelpful; the baseline of 3 applies because the schema handles parameter explanation.

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 identifies a specific verb ('Retrieves'), a resource ('geographical interest data'), and the core input ('keywords'), so an agent can understand what the tool does. It does not explicitly differentiate from siblings like get_growth or get_trends, but the geographic focus is reasonably distinct.

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 siblings such as get_ranked_trends, get_growth, or get_news_by_location. No exclusions, prerequisites, or alternative routing is provided, leaving the agent to infer usage from the name and schema.

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