dynadot_domain_appraisal

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 behavioral disclosure. It only mentions the use of the v2 endpoint but does not reveal other important traits such as authentication requirements, rate limits, return format, or whether the operation is read-only. This is insufficient for an agent to fully understand the tool's behavior.

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 consists of only two sentences, each conveying essential information. It is front-loaded with the core purpose and efficiently includes a technical detail about the API version. No unnecessary words or redundancy.

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 covers the basic purpose. However, it does not describe the return value or provide any usage considerations (e.g., domain validation), leaving gaps that an agent would need to infer or handle with uncertainty.

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 has 0% description coverage for the only parameter 'domainName'. The description merely implies it is a domain name but adds no specifics about format (e.g., with or without TLD), constraints, or validation rules. It fails to compensate for the lack of schema documentation.

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 explicitly states the action 'Get an estimated value' and the resource 'a domain', making the purpose clear. It also differentiates from siblings by noting the API version distinction (v2 vs v3), which is helpful for agents familiar with Dynadot's API. No other sibling tool performs appraisal, so it stands alone.

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 should be used when a domain appraisal is needed. It provides clear context about when to use it, but does not explicitly state when not to use it or provide alternatives. However, since no alternative appraisal tool exists among siblings, the guidance is adequate.

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