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

With no annotations provided, the description carries the burden. It indicates a read-only operation ('Liest') and discloses that the result includes ranking and URLs. However, it does not mention authentication requirements, error handling, or what happens if the listing does not exist. This is adequate for a simple getter but lacks depth.

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 immediately conveys the core function. It is front-loaded with the action 'Liest' and the resource, and every word adds value. No wasted text.

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 one-parameter read tool with no output schema, the description is reasonably complete. It states what is returned (images, rank, URLs) and implies a list structure. However, it could optionally mention that it returns a collection or require authentication, but given the low complexity, this is a minor gap.

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 already covers the single parameter listing_id with a clear description ('Numerische Etsy Listing-ID.'). The tool description adds no extra meaning about the parameter, so the baseline of 3 applies since schema coverage is 100%.

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 'Produktbilder eines Listings' (product images of a listing) with clear additional details about including rank and image URLs. This distinguishes it from sibling tools like etsy_get_listing and etsy_get_listing_inventory, making its purpose unambiguous.

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 provides no guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or reference sibling tools. While the name is self-explanatory, explicit usage guidance is missing.

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