dynadot_get_listing_item

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

No annotations are provided, and the description only indicates a read operation ('Get details') without disclosing any behavioral traits such as side effects, authentication requirements, or rate limits.

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 conveys the essential purpose without any unnecessary words or repetition.

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 retrieval tool, the description is mostly complete, but it could mention what the return value contains (e.g., listing details) since there is no output schema. However, given the simplicity, it is adequate.

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 input schema already describes 'listingId' as 'Listing ID from get_listings' with 100% coverage, so the description's addition of 'by listing ID, not domain name' reinforces but does not add new semantic meaning 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?

The description clearly states the tool's function: 'Get details for a single marketplace listing.' It also distinguishes by specifying 'by listing ID, not domain name,' differentiating it from sibling tools that might use domain names.

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 the tool is for fetching a single listing using a listing ID, but it does not explicitly state when to use this tool versus alternatives like dynadot_get_listings or dynadot_download_all_listings, nor does it provide any exclusions.

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