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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only mentions that accessories come with codes and images, but does not clarify that results are filtered by productId, the response structure, pagination, or any potential limitations. This is minimal at best.

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 an example, no filler words, and the core concept is front-loaded. It earns its place and is appropriately concise for a simple get tool.

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 tool with one parameter and no output schema, the description is somewhat complete but leaves out the crucial connection that the returned accessories are tied to the provided productId. It also does not mention the output format, but for a straightforward read tool it is minimally viable.

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?

The schema description for productId is 100% covered (states numeric ID, product title, or slug), so the baseline is 3. The description does not add any meaning about how productId affects the results; the relationship is implied by the tool name but not explicitly stated.

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 the resource (accessories) and gives concrete examples (antistatic kits, lances, brushes), which makes it clear the tool returns accessory information. The verb 'get' is present in the tool name, and the description distinguishes it from sibling tools by focusing specifically on accessories, though it does not explicitly state 'returns' or 'lists'.

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 alternatives such as getProductData or getFilterCleaningSystems. No prerequisites, exclusions, or scenarios are mentioned, leaving the agent to infer usage purely from the name and description.

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