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

No annotations are provided, so the description carries the full burden. It clearly states the operation is a read ('Liest'), implying it is non-destructive. However, it does not disclose any further behavioral context such as authentication requirements, rate limits, or error conditions, which are relevant given the surrounding auth tools.

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 concise sentence that is front-loaded with the action and resource. Every word earns its place, and there is no redundant or vague filler.

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?

This is a simple one-parameter lookup tool with no output schema. The description adequately conveys the tool's purpose and input, making it sufficient for basic use. It does not explain the return structure, but the simplicity of the operation lowers the need for that detail.

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% with the parameter 'listing_id' already described as 'Numerische Etsy Listing-ID.' The tool description repeats this by saying 'anhand seiner numerischen Listing-ID,' which adds no new semantic detail. The baseline of 3 applies because the schema fully documents the parameter.

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 uses the specific verb 'Liest' (reads) and identifies the resource as 'Detaildaten eines einzelnen Listings' (detail data of a single listing). It clearly differentiates from sibling tools like etsy_list_listings by specifying a single listing, and the method (by numeric listing ID) is stated.

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?

The description implies when to use the tool (when you need details of one listing rather than a list), but it provides no explicit alternative guidance or exclusions. Sibling tools such as etsy_get_listing_inventory and etsy_get_listing_images are not mentioned, leaving the agent to infer the distinction.

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