Behavior3/5

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

The description lists what the tool returns (name, parent, children, product count) but provides no additional behavioral context such as read-only nature, rate limits, authentication requirements, or error handling. Since no annotations are provided, the description carries the full burden, and while it is not misleading, it 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that states the purpose and expected output elements without any redundant words or filler. It is front-loaded and scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple lookup tool, the description covers the key output details and the parameter semantics are fully in the schema. However, the lack of an output schema means the description should ideally clarify whether the response is a single object, how missing categories are handled, or whether the hierarchy is full or partial. It is nearly complete but leaves a small gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for both parameters (domain and category). The description adds no extra meaning beyond what the schema already provides, such as the format or constraints of the category ID or how domain affects results. Baseline 3 is appropriate since schema handles parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Look up') and resource ('category details'), with concrete attributes (name, parent, children, product count). This clearly distinguishes it from sibling tools like keepa_get_product or keepa_get_price_history, which serve different purposes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no indication of when to use this tool versus alternatives. It does not mention exclusions or when a different keepa tool would be more appropriate, leaving the agent without guidance for tool selection among many similar lookup tools.

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