netintel_domain_appraise

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

With no annotations, the description carries the full behavioral burden. It discloses that valuation uses transparent heuristics and returns a value tier plus a 0-100 quality score, which is useful. However, it does not state auth requirements, rate limits, side effects, or whether the operation is purely read-only, and the truncated ending leaves the disclosure incomplete.

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 content is front-loaded with the main verb and resource, and it avoids unnecessary padding. However, the sentence is truncated with a dangling 'so…', making it structurally incomplete and reducing confidence in the intended full message.

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 tool with no output schema and no annotations, the description should be self-sufficient. It explains the heuristic basis and return shape in part, but the truncation, lack of parameter format detail, and absence of sibling guidance leave meaningful gaps.

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 0% and the single 'domain' parameter is undocumented in the schema. The description mentions 'domain name' but adds no format guidance, examples, or constraints such as whether it accepts bare domains, URLs, or subdomains. It does not compensate for the missing 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 names a specific verb and resource: 'Estimate the market value tier of a domain name.' It also lists the heuristics used and the outputs, making the purpose clear without opening the schema. It does not explicitly differentiate itself from sibling tools like netintel_tld_price or netintel_domain_vet, but the valuation focus is distinct enough.

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 explicit when-to-use guidance, no mention of alternatives, and no conditions or exclusions. The description implies a domain valuation context but does not help an agent decide between this tool and related siblings such as netintel_domain_age, netintel_domain_report, or netintel_tld_price.

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