smartscout_brand_coverage

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

No annotations are provided, so the description must carry the full behavioral burden. 'Get' implies a read operation, but the description does not disclose permissions, pagination, rate limits, return format, or what 'coverage' actually represents, leaving significant ambiguity for a data-retrieval tool.

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 short sentence with no wasted words and is front-loaded. However, for a tool with four parameters and a non-obvious domain concept, it is too terse to be considered well-structured guidance.

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 four parameters, no annotations, no output schema, and no required parameters, the description is not complete enough. It does not explain what the response contains, how seller coverage is defined, or how the optional filters interact.

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 the schema already documents brand, limit, sellerId, and minRevenue. The description adds no parameter semantics beyond what the schema provides, which establishes the baseline of 3.

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 gives a verb ('Get') and a resource area ('seller coverage information for brands'), so the general purpose is identifiable. However, 'coverage information' is vague and the description does not distinguish this tool from sibling brand tools like smartscout_brand_details, smartscout_brand_growth, or smartscout_brand_search.

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, when not to use it, or which sibling tool to choose instead. The agent is left to infer from the name alone that this tool relates to brand-level seller coverage.

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