smartscout_brand_growth

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

With no annotations at all, the description carries full behavioral burden and discloses none of it: no statement of sort order, read-only nature, pagination, or whether growth is absolute or percentage based. A single phrase cannot cover the behavioral profile of an unannotated 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?

A single front-loaded phrase with zero filler, which is efficient. It is arguably too terse rather than wasteful, so it does not reach the top score.

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 simple filtered read tool with all three parameters documented in the schema and no output schema to explain, the definition covers the essentials. It still omits return-shape and ranking semantics, which an agent would need to interpret results.

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 limit, period, and minRevenue are already documented in the schema, establishing a baseline of 3. The description adds no extra syntax or units (e.g., what revenue is measured in, how growth is computed per period) beyond the schema.

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?

States a specific verb ('Find') and resource with a ranking qualifier ('fastest growing brands'), which is more informative than a tautology. It does not distinguish itself from sibling brand tools such as smartscout_brand_search or smartscout_brand_details, so an agent must still infer the difference.

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?

No indication of when to pick this tool over the ~8 sibling brand/keyword tools, and no prerequisites or exclusions are given. The only implicit guidance is the growth-ranking frame.

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