Behavior1/5

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

No annotations are provided, so the description must fully disclose behavioral traits. 'Get domain details' implies a read-only operation but does not specify authentication needs, rate limits, error handling, or response format. It lacks essential context for safe and effective use.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with a single phrase 'Get domain details', which is front-loaded and wastes no words. However, this brevity comes at the cost of completeness, as it under-specifies the tool's functionality.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (1 parameter with no schema descriptions, no annotations, no output schema, and many siblings), the description is incomplete. It does not address parameter meaning, behavioral traits, or differentiation from alternatives, making it inadequate for effective tool selection and invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 1 parameter with 0% description coverage, and the description does not explain the 'name' parameter's purpose, format, or constraints. It fails to compensate for the schema's lack of documentation, leaving the parameter's semantics unclear.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get domain details' restates the tool name 'get--v4-domains-name' with minimal elaboration, making it tautological. It specifies the verb 'Get' and resource 'domain details' but lacks specificity about what details are retrieved or how it differs from sibling tools like 'get--v4-domains' or 'get--v3-domain-tag'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. With many sibling tools (e.g., 'get--v4-domains', 'get--v3-domain-tag'), the description offers no context, prerequisites, or distinctions, leaving the agent without usage direction.

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